COLEOPTEROLOGICAL NOTES ^FOR THE YEAR 1886. Cychrusstenostomus was found several times under _fungi where, ^I _suppose, ^it hadstationed itselfinorderto feed upon^theinsectsinhabiting the fungus.

Amara

impuncticollis ^is found on Lepidtum virginicum during ^the warmer _parts of the day ⁱⁿ

May;

^{whether or not it feeds on} the plant I

am

not certain.

Lebia_ptilckellawas found understoneson

May

¹⁸and October8.

Cercyonprcetextatum and Silpha americana were foundin fungi.

The _following Coccinellidce are found on Asclepias cornuti^: Hippo- damia _glacialis,convergens, parenthesis, Coccinella noi'emnotata,Adalia bipunctata,Brachyacantha ^ursina.

Dermestescaninusin avacated bird's nest.

Cryptorhopalum^triste,

common

on Taraxacumdens-leonis, inMay.

Cryptarcha strigata, infungiwhere Pocadius^helvolusiscommon, ^also onbruised_{pears, in}September.

Tenebrioidescorticalisand Adeloceradiscoidea

common

underthebark ofdead Pitch pines (Pinus rigida}, where, on February 10, I secured a single specimen ^ofDicercapunctulata.

Acmceoderaculta

common

on TaraxacuminMay.

Oxyomusporcatus

common

in dried horsemanurein April.

The_species of Troxflyinthe hotsunshineinApril (T.monachus and unistriatus), are attractedbylight^at night (T.terrestrtsa.r\d unistriatus), andarefoundin filth(T. terrestris, orallied species).

Macrodactylussubspinosuswas _unusually

Molorchusbimaculatus,

common

on Viburnumprunifolium during ^the

latterpart ofMay.

Colaspisbrunnea abundant on Ambrosiaartemisicefolia.

Mr. Smith

called attention to a peculiarity observed

by him

in the

antenna

of Cressonia juglandis.

They

^{have in the male}

two

branchesto each side of each_{joint, precisely}^{as inthe Satur-}

niidaj. This feature isunique^intheSphingidae^of

North America

;

nor did he

know

ofitsoccurrence ⁱⁿ exotic genera.

He _empha-

sized the relation of the Smerinthidsto the

Bombycids,

^even

80 ENTOMOLOGICAL ^SOCIETY

thoughthe venation of the

wings

^{and the larvae are} essentially sphingiform.*

Mr. Smith

also stated thathe

had

foundthat

among

^{the insects}

usually

named _Euerysthia phasma, ^two

species

were embraced which

differeddecidedly, not onlyⁱⁿ markings, but ⁱⁿ structure. f

Mr. Smith

also offered

some

remarks

on

the

North American

species of Callimorpha. ^Inarranging^{the material of the}

U.

S.

National

Museum

he had

come

to the conclusion, from _{a study} of theseries of

Callimorpha

^inthe collection, thatmost of those forms

now marked

as varieties

were

_really

good

species.

He

said that, ^at

some

future time, he

would

_{present a} careful study of the forms._|

Mr. Schwarz

presented the following ^listof Scolytids found

by him on Pinus

_inops, ⁱⁿ the _vicinity of

Washington

^:

Gnatho-

trichusmateriarius, asperulus, Pityophthorus sparsus,pullus, hirticeps, puberulus,

Hypothenemus

dissimilis,

Xyloterus

bivittatus (probably imported from ^{farther north),} Xyleboriis pubescens, ccelatus, Dryoccetes affaber,

Tomicus

calligraphus, cacographus, pint,

Carphoborus

bifurcus,

Dendroctonus

tere- brans, Hylastes porculus, ^tenuis*

Hylurgops

pinifex.

The mode

of

work

^of

many

^{of these still remains}

^unknown. Among

the less

common

_species ^is

Pityophthorus

pullus, the galleries of

which were

exhibited and _explained.

The

female beetle (or both sexes _?) constructsunderthe bark of thetrunka rather_large, roundor ovalcentral chamber, from

which

from threetofivelong and _slightly undulating gallerieslead off invariousdirections, but usually

more

orless

upwards

^or

downwards. The

larval galleries donot presentanyparticularfeatures, butare rathershorter than

in allied species. Allthese _galleries are

more

within the bark than in the outermost_{layer of}

wood.
