SOME NEW GENERA IN THE CYN1POIDEA.

By ^{WILLIAM H.} ASHMEAD.

Family FIGITID^.

Subfamily

Kiefferiella, ^{n. n.}

(=

Kiejferia

Ashm.,

preoc. ⁱⁿ Diptera).

This genus

comes

next to Figites Latreille, but is quite ^dis tinct in having ^thehead

and

thorax _coarsely rugosely punctate,

by

^{the antennae} being filiform, the _joints cylindrical, the third shorter than the fourth,

and by

^the

abdomen

being compressed, the second

segment

being ^aslong ^as3

and

₄ united.

Type: K. rugosa Ashm.,

^{taken in the Santa}

Cruz

_Mts., California.

The

_genus is dedicated to

Abbe

_{J. J. Kieffer,} Professorat Bitche,Deutsch-Lothringen,

who

has so ably

monographed

^the

European

Cynipidae.

Subfamily EUC OILING.

Zamischus Ashmead.

The

_type of this genus,

Z.

brasiliensis,

was

taken

by Mr.

Herbert

H. Smith

in Brazil,

and

is the

most

_striking

form

_yet discoveredin this group, being unique

and

quite unlike any^other

known

Eucoiline.

The

metathorax is

produced

posteriorly ^into a long neck, the length of the hind _coxae, while the

abdomen

is

attached to this

by

^an abnormally long, slender

and smooth

petiolethe length of the

body

^{; the antennae}

and

the venation of thefront

wings

^{are also} peculiar, the former being very long, gradually thickened towards apex, while^thecostal and marginal

cellsare confluent, the marginal ^cell being onlypartiallyformed, entirely

open

^all along ^{the front} margin,

much

as in

Onychia

Haliday. ^It

shows some

_affinitywith the Liopterinae.

Type: ^Z.

brasiliensis

Ashm. _(Chapada,

_Brazil.)

Tropideucoila Ashmead.

This genus ^{isallied to}

Disorygma

^{Forster,butis}easily separ atedby having 5 longitudinal ^carinae

on

the

mesonotum, and by

the scutellum being ^bidentate.

The

antennae are

i3-jointed, filiform.

Type:

^T. rufipes

Ashm.

_{(Chapada, Brazil.)}

Promiomera Ashmead.

Alliedto

Miomera

Forsterbut_{easilyseparated}

by

the antennae, which, ^{in the} $, are n-jointed, filiform, tapering^offat apex; ⁱⁿ

3%

long, i3-jointed, the third joint very

much

shorter than the fourth.

Type:

^P. filicornis

Ashm. _(Chapada,

_Brazil.)

222 ENTOMOLOGICAL SOCIETY Odonteucoila Ashmead.

This genus ^is easilyrecognized

by

^{the scutellum}

which

endsin a tooth or _spine,

and by

^{the antennas}

which

are long, ^filiform, withthe third joint

much

shorter than thefourth.

Type:

^O. chapadce

Ashm. _(Chapada,

_Brazil.)

Trissodontaspis Ashmead.

The

scutellum in this genus ^is unique^{in the} group, ^the

cup

being ^{modifiedintoacarina}

which

isgradually^dilated posteriorly

and

ends in a tooth-like projection, whilethe scutellum proper has a tooth each side posteriorly,the scutellum thusappearing^as

iftridentate,

when viewed from

above.

The

antennas are

un

usually long, the _joints being long

and

cylindrical, the third joint slightlycurved ; the

pronotum

^{iselevated into a} sharpridge

and

_{deeply emarginate medially,} while the

mesonotum

is longer than wide.

Type:

T. rufipes

Ashm.

_{(Chapada, Brazil.)}

Dieucoila Ashmead.

This genus^differsfrom all others

by

having^thehead

and

thorax finely,opaquely sculptured,

by

^{the scutellum,}

which

has

two

large, oblong shallow ^{foveaa at}base,

and by

peculiarities of the antennae,

which

are long, the joints cylindrical, long, but grad ually thickened, the third joint a ^little shorterthan the fourth.

Type: D. _subopaca Ashm. _(Chapada,

_Brazil.)

Zaeucoila Ashmead.

This genus ^is easily

known _by

its short, robust form,

by

^the short closedmarginal ^cell,

which

is hardly longerthan wide,^the second abscissa of the radius being rather strongly curved out wardly

and

_by the short

mesonotum which

hasa delicate carina

down

the _center, the

cup

^{of the scutellum} being large, almost round.

Type: Z.

unicarinata

Ashm.

_{(Rio de Janeiro.)}

Pseudeucoila Ashmead.

This genus^isproposed^fora

number

of species placed^atpresent in thegenus

Eucoila

DallaTorre

and

Kieffer.butnot

Westwood.

The

type of Eticoila

Westwood

is

E.

crassinervis

Westw.,and

Psilodora Forster^is a

synonym

^{of it. In} Pseudoeucoila the

wings

^arepubescent

and

the marginal ^{cell is closed.}

Type: Eucoila

(Cothonaspis} trichopsila Hartig.

The

_paper

was

discussed

by

^{Drs. Gill}

and Howard. _Speaking

of gall-wasps,

Mr. Ashmead

stated that the so-called

"potato

gall

"

(Tribal/a

batatorum

_Walsh),

which was

in reality a root- gall on

Rubus

or Rosa,

was

described

and named

_by

Walsh

from specimens given

him by

^{a farmer}

who

_reported thatthey

were
