The species of <I>Diludia</I>

OF WASHINGTON. 103

Mr. Smith

said that,

on

the occasion of a recentvisittoPhila- delphia, he

had

an opportunity ^of looking ^over carefully the Sphingidag ^{of the collection of the}

Am.

Ent. Soc.

Many

^{of these}

aredetermined

by Mr.

^Grote,

and

the types of^hispapers

on Cuban

Sphingidas ^{arethere. In the} genus

Diludia* Mr.

Grotehas three species,

jasminearum,

^{brontes and} leucophceata.

The

_species

are notat all congeneric.

Brontes

is the type of thegenus and has a_large,prominent^head,

armed

fore tarsi

and

_producedthorax.

He

pointed out ^{the difference}

between

the species^{referred to}here, and claims that neither brontes nor leucophceata are properly

members

ofour_fauna, but

must

be

dropped from

^ourlists. _Jas-

minearum

^is entirely differentgenetically from the others.*

Mr. Howard

_spokeat

some

_{length of}arecent

trip^to

Cambridge,

Ithaca, and Philadelphia.

He

_praised the extensive biological collection ofinsects in theAgassiz

Museum, ^and

exhibited a case of a Caddis

Worm {Aspatherium

picicorne}^, given

him by

^Dr.

Hagen. and which had

^{been infested}

by

^an

Ichneumon

_id,

Agrio-

typus

armatus. The same

_parasite is

known

to infest Spathi- dopteryx {Phryganeidce}.

He

mentioned thefact that the col- lection of Braconidce, _presented

by

^{Dr. Foerstertothe}

Peabody Academy,

^is

now

intheAgassiz

Museum,

^andprior^toitsremoval

it had

become

_badly

damaged, and

^that

now

less thanhalf of the species areⁱⁿ condition for comparison.

He

then described the systematic ^collection

which

Prof.

Comstock

has broughttogether atthe Cornell University, Ithaca,

N. Y.

This is already a

most

excellentreference collection.

The

Lepidoptera have been^deter-

mined by

Grote,Morrison,

and

Mrs. Fernald; the

Hemiptera by

Uhler_; theDiptera

by

^{Williston; the}Orthoptera

by Scudder and

Pierce,

and

the

Hymenoptera by

^Cresson.

He

also described several ingenious contrivances invented

by

^Prof.

Comstock, and

in usein his laboratory.

Among ^them

^the block-system ^{for the} arrangement ^{of a}

permanent

collection, his darkened _glass tubes forthe observation of pith-inhabiting

Hymenoptera,

^hisautomatic apparatus ^{for the inflationof several larvae at once, his cabinet} with insulated drawersfor colonies of _ants,

and

his cartridge^belt for collecting purposes.

He

did not dwell

upon

^{the collectionof}
