during the _{past year,} the _following apparently

For one

was found

_necessary to erect a

Hylotrupes juniperi ^n. sp.

Male: Elongate,rather robust,subdepressed,shining black. Antennae three-fourthsaslong^asthebody. Thorax roundedonthe_sides,suddenly narrowedtowardsthe base,w^rhichisslightly tubulate, the sides aredensely andconfluentlypunctured, ^thediscwith threesmooth longitudinal eleva- tions, one median reaching from base to middle, and a crescent shaped one on each side forming ^a somewhat broken circle. Elytra each with twoindistinctlines, surface verydenselypunctured, ^the punctureslarger and less dense on the basal _half, and becoming very ^small towards the apex, sparsely clothed with short black recumbent hairs. Femora not clavate. Fifth ventral segment truncate ^behind. Length²²

with the _{grain of} the

^{half in the}

half

PROCEEDINGS ENTOMOLOGICAL SOCIETY

in the

sapwood,

occasionally

one

in the

sapwood. Larva when

full

grown makes ^burrow

straight intothe

heartwood and

_pupates.

This _species is

very

closely ^allied to Hylotrupes amethystinus Lee.,

but

is distinguished

from

that _species

by having

shining black _elytra without

any

^{trace of the violet color.}

Hylotrupes amethystinus ^Lee. has

somewhat

of a similar habit but as far as

known,

only attacks

dying and

felled Libocedrus

and

_Thuja.

The

larva

works under

the _bark,

making ^broad winding

excavations, eating the inner

bark and

outer

sapwood, sometimes

separating the

bark from

the

wood, then

^{enters the}

wood, sometimes burrowing

^{to the}

heartwood where

the

burrows become

longitudinal,

pupating

^{in either}

bark

or

wood, but

usually in the heartwood.

Paratimia

new

genus.

Eyesmoderatelyfinely granulated, deeply emarginate, partly envelop- ing the base ofthe antennae, but not as deeply emarginate ^{as inAtirnia.}

Head

broad and _short, the front perpendicular.

Labrum

transverse, ciliatedwith long^hairs. Palpiunequal, themaxillary about^twiceaslong as the labial last joint triangular. Antennae slender, shorter than the body^{in both}sexes, 11-jointed;second _joint lessthan half aslong ^{as the} thi d, which i? a little shorter than the fourth, ^fifth joint longest; punc- tured and _pubescent. Front coxa? rounded, narrowly separatedby ^the prosternum, ^cavitiesangulatedexternally,completely^closedbehind;mid- dle coxa; separated by ^the mesosternum about twice the distancewhich separatesthefront_coxa?,cavities slightlyangulatedexternally,completely closedby the sterna. Mesosternum concave betweenthe _coxa?, emargi- natebehind. Metasternum_deeplyemarginate behind. Legsshort,femora slightlyclavate, front^tibisewith _one, middleand_posteriorones withtwo small spurs, hindtarsi with firstjoint equal^tothe twofollowing united.

Type:

Paratimia

conicola n. sp.

This

new _genus

_belongs to

Leconte and Horn's

tribe Atimiini but differs

from

the

genus Atimia by having

^the front coxse nar-

rowly

separated

by

the prosternum, the ^cavities angulated ^exter- nally, eyes not quite as deeply

emarginate and

the last joint of the maxillary palpi beingtriangular. In _general

form

itresembles a

Lamiine

but thefront tibise are without the obliquegrooves.

Paratimia conicola _{n. sp.}

Male: Elongate,slender,subcylindrical. Thoraxsomewhat_cordiform, not widerthan long, front anglesrounded, ^sides rounded _justbefore the middle, then obliquely narrowed towards the base, surface fusco-piceus, coarselyand_{thicklypunctured,}andratherdensely^clothedwith longpros- trated reddish-brown _hairs, those on the _posterior half and underside whitish.

DESCRIPTIONS OF NEW NORTH AMERICAN MICROLEPIDOPTERA.

BY AUGUST

BUSCK.

In

one

of

my

early papers (Journ.

N.

Y. Ent. _{Soc., vol.}VIII, 1900, p. 234), ^I expressed^the ^opinion, that in the then _existing unsatisfactory state ^of our

knowledge

^of

American

_Microlepi- doptera, ^it

was

of little value _(or worse) ^{to describe} promiscu- ously

new

_species

from

collected material; only

when _working up

^a

group

systematically didit

seem

to

me

excusableto describe species of

which

the biology

was

not

known.

This attitudehas influenced

my

production of descriptive

work

during the past years

and

I

have

described

new

_{species only as}

the

demand

for

names from

correspondents necessitated _it,or

when

otherconsiderations

made

itdesirable or obligatory.

There

are for this reason

hundreds

of

Micros

asyet undcscribed ⁱⁿ the collection of the

United

States National

Museum.

I still

have

a disinclination for

new

_{species of}

which we know

nothing

more than

the
