^{erects seven}

new

genera, describingthevenation

and

genitalic characters of each.

The

venational characters

seem

to

be

of

an

indefinite nature,

and we _might

as well frankly ^re- gard the genera ^as

founded on

the genitalia alone.

These

cer- tainly

show

well

marked and

distinctive characters. I

have

received

from

Dr. Felt

photographs

^of

many

^{of his slides}

^and

have had

others prepared

by

the kindness of Mr.

H.

S. Barber.

It is of especial interest that the _genitalic groups

run

_largely

parallel tothosedefined

larval characters, ⁱⁿ

firming^{larval affinities}

where

it

had been

heretofore

supposed

that these

were

contradicted

by

^{the adults.}

A

case inpoint^is that of

Janthinosoma musicum,

Culex jamaicensis

and

Taznio- rhynchussignipennis.

These

larvaeare

very

peculiar

and

essen- tially alike.

The

adults

have been

considered unrelated;

but

the _'genitalia are in

some

_respects

_very

similar

and

_place

these

forms

close together. Thisleads

me

toconclude that the genitalic groupings,

where

reinforced

by

^the larval ones,

show

natural _divisions,

and

I

am,

therefore, in accord with Dr. Felt

inusing

them

asthebasis for genera. ^{It is}truethatingeneral practiceother characters

than

these are preferable,

owing

^tothe necessity of preparing the specimens

and

to the fact that the charactersare

shown by ^one

^sexonly,

and

that the

one

_{not gen-} erally ^{collected. I} believe, however, that ^since the groups^are natural ones it is probable that other recognition characters will

be

found. If they should not be, ^it

might be

^{better to} reduce the _genitalic genera ^to subgeneric rank, ^for practical reasons,

without

_thereby losing sight of their value. ^It

seems

inevitable that the

genus

^{Culex shall}

be

_divided,

and

the _geni- talicdivisions are

more

natural

than

those _recently

founded on

scales

and

_papal structure.

As

to the latter it is necessary ^to

remove and mount

the _palpi,

which

is as practically objection- able a process ^as

any

connected with the

study

^{of the cT} geni- talia.

The

sketch herewith of

Grabhamia

cantator Coq.,

shows

the

names

_applied to the different _parts.

They vary much

ⁱⁿ

amount

of

development

^{as well as in}

shape

^{in the different}

species. Anopheles

shows

the simplest arrangement, scarcely distinguishable

from

the Corethrinae. This is in accord with the larval characters, since Anopheles ^{larvae are}

very

^{close to}

some

Corethrid _{forms, as} Eucorethra

and

Dixa.

The

Culicinae

have

a small articulated _tip to the terminal

segment

^{of the}

clasper,

which

_appears to

be

_lackingin the_Aedinae, althoughⁱⁿ UranotcEnia sapphirina ^{there is} a small _spine

much

_resembling

it

and _probably

representing ^its rudiment.

The

_species of Culex

show

the

most

differentiation, especially inthetrueCulex or pipiens

group and

these arethe

most

specialized^larvae.

We

have

thus a

concordance

in general as well as special characters

between

_genitalic

and

larval structure

I

have thrown

the

forms known

to

me

into a synoptic ^table of genera,

which

follows.

A few new names

aresupplied^{to fill} gaps ^{left in Dr. Felt's} groupings or as corrections.

Genus ANOPHELES Meigen.

Type:

^{bifurcatus Linn.}

The

_{genitalic type has}

been

_figured

by Theobald and

Felt.

Nine

species are recorded

from North

America, ^viz: maculipennis Meig.,

plumbeus

^Hal., bifurcatus Linn., punctipennis Say, pseudopunctipennis Theob., francisca-

nus

McC., ^barberiCoq., crucians Wied., ^eiseni Coq.

Genus CELLIA Theobald.

Type:

pulcherrima

Theob. The

_genitaliawill

probably

prove similar to those of Anopheles. ^I

have

not seen

them

of either of the _species recorded

from North

_America, viz: argyrotarsis Desv., albipes

Theob.

Genus CYCLOLEPPTERON Theobald.

Type:

grabhamii Theob., the only species recorded

from

our region.

The

genitalia are

unknown

tome.

Genus ARRIBALZAGIA Theobald.

Type:

maculipes

Theob.

This _species is recorded

from

Trinidad

and

^willdoubtless

be found

in thesouthern portion ^of

our

_region.

The

_genitalia

have

not

been examined.

Genus PSOROPHORA _Desvoidy.

Type:

^{ciliata Fab.}

We

are credited with three _species, viz:

ciliata Fab., howardii _Coq., scintillans

Walk. The

genitalia of ciliata

have been

_figured

by

^{Dr. Felt.}

Genus MEGARHINUS _Desvoidy.

Type:

hczmorrhoidalis Fab.

We

^are credited

with

seven species, viz: rutilus Coq., portoricensis

Von

_{Rod., ferox Wied.,}

grandiosus Will., h&morrhoidalis Fab., longipes Theob., separa- tus Arrib. Mr.

Barber

has

made me

a nice

mount

of the _geni- talia of portoricensis,

from which

the characters given ⁱⁿ the table

were

taken.

Genus STEGOMYIA Theobald.

Type:

fasciata Fab. Besides this species, sexlineata

Theob.

may

^occur

^with

^us.

^The

genitalia of fasciata are distinctive as

may ^be

^inferred

^from

the preceding^table.

Genus PNEUMACULEX, ^new

genus.

Type:

signifer Coq. This _species is peculiar in

many ways and

deserves adistinct generic appellation.

The

larvahas be- sides the peculiar dorsal plate

an enlargement

^{of the tracheal} tubesinto a sort of bladderinthe_thorax, suggesting ^Corethra.

In

the cT genitaliatheside pieces are conic,

without

apical lobe^; basal lobe small

but

_bearing

two

stout setae; terminal _clasp slender, enlarged a ^little

outwardly

with a multiple articulated tip.

Harpes

^{short,chitinous,} concave, with^trifid

apex

^; harpa- gones small, slender, chitinous, acute; another _{pair of} appen- dages

more

basally placed, shorter

than

the harpagones, with a terminal

hook;

a median, divided, double-tipped

membrane

(unci?).

WASHINGTON. 47 Genus TJENIORHYNCHUS

Arribalzaga.

Type:

^titillans

Walk. Theobald

takes fasciolatus Arrib. as the type^of T&niorhynchus,

but

thefirstspecies^is t&niorhynchus Arrib. (nee

Walker) =

titallansWalk.,

and

should

be

the_type.

This_speciesis also the type^of

Mansonia

Blanchard,

which

^will

become

a

synonym

^of Tceniorhynchus.

The

_species has

been

recorded

from

Trinidad

and

will doubtless

be found

in the

southernmost

_part of our _territory. I

do

not

know

the _geni-

talia.

Genus COQUILLETTIDIA, new

genus-

Type:

perturbans

Walk. Theobald

_places this species in Tceniorhynchus ^Arrib.,

but

not _correctly, I believe.

The

_geni-

taliaare peculiar. Dr. Felthas prepared

them from

a

specimen which

^I senthim,

but

the _figure is not r.

produced

^{in his bulle-}

tin.

The

characters

may ^be

gathered

from

the table.

Four

species are referred here, ^viz: richardii _Fie., perturbans Walk., confinis Arrib.,nigricansCoq.

Genus FELTIDIA, ^new

genus.

Type:

jamaicensis

Theob.

^{Dr. Felt} has

taken

jamaicensis as the type ^of

Grabhamia, but Theobald mentions

^{first dorsalis} Meig.

Of

jamaicensis,

Theobald

_gives a

rough

figure

and

Felt a

good

photograph.

We ^have

three species at present^referable here, jamaicensis Theob., cyanescensCoq./signipennis Coq.

Genus JANTHINOSOMA

Arribalzaga.

Type:

^discrucians

Walk. We have

five species, viz: musi-

cum

_{Say, posticatum Wied.,} lutzii Theob., discrucians Walk., varipes Coq. ^{Dr. Felt} has prepared the _genitalia of

musicum and

lutzii

which

are

much

^alike.

He

has _figured the former.

Genus JOBLOTIA Blanchard.

Type:

ni-veipes

Theob. The name

is a substitute for

Theo-

bald's Trichosporon (nee Trichosporus Macq.)

The

_{single spe-}

cies is recorded

from

Trinidad,

but probably

occurs with us.

I

have

not seen the _genitalia.

Genus ECCULEX

Felt.

Type:

syhestris Theob., the only species. It has

most

re-

markably

distinct genitalia

and

is apparently not^{atallallied to}

Grabhamia

as

one would have

_supposed. ^{Dr. Felt has}

pub-

lished a photograph.

Genus PSEUDOCULEX, ^new

genus.

Genus CULICELSA

Felt.

Type:

t<zniorhynchus Wied., the only species properly ^re- ferred here. Dr. Pelt

adds

aurifer Coq.,

but

I consider this to represent a ^distinct generic type. ^I

am

doubtful, moreover,

whether

the

hook on

_{the harpes} is to be considered a _generic character. Ifnot, Culiselsa^fallsin with the_following.

Genus GRABHAMIA Theobald.

Type:

^dorsalis Meig.

Synonym,

^Culicada Felt, type cana- densis

Theob.

I

have

not seen the _genitalia of dorsalis,

but Theobald

_figures the larva of it

and

the genitalia of a _closely allied species. This is our _{largest genus.} Sixteen species are referred here with _certainty, viz: canadensis Theob., dupreei Coq., sollicitans Walk., cantans Meig., atropalpus Coq., cantator Coq., uaripalpus Coq., ^curriei Coq., impiger Walk.,-'lazarensis F.

Genus PROTOCULEX

Felt.

Type:

Dr. Felt has _briefly described the _genitalia,

though he

^{has not} figured

them.

I

Genus CULEX

Linnaeus.

Type:

pipiens Linn.

As now

restricted, the

genus

^{is a small} one.

But

five species are certainly referred to it, viz: pipiens Linn., ^tarsalis Coq., restuansTheob., fatigans Wied., ^salinarius Coq.^{; to}

which

should

probably be added

^secutor

Theob.

Genus MELANOCONION Theobald.

Type:

^atratus

Theob. Though

belonging near Culex the

male

_genitalia

show

a distinct type.

A

second _{species, spis-} sipes Theob., ^is recorded

from

Trinidad.

Genus DEINOCERITES Theobald.

Type:

^cancer

Theob. The

_genitalia

have been

_figured

by Theobald and

are very peculiar.

The same may ^be

^{said of}

most

ofthe Aedinae.

Genus AEDES _Meigen.

Type:

^cinereus

Wied. Two

species are credited toour_fauna, viz: fuscus O.-S.

and

_perturbans Will.

The

by

^{Dr. Felt.}

Genus HOWARDINA Theobald.

Type:
