THREE INTERESTING ORTHOPTERA FROM THE VICINITY OF WASHINGTON,

^{D. C.}

BY

A. N. CAUDELL, BureauofEntomology.

To

our local faunathree species of Orthoptera^{are to}be added.

One, Cryptocercus punctulatus Scudder,

was

taken on _Cupid's

Bower

_{Island, Md.,} a smallisland inthe

Potomac

River

some

dis- tance below Great Falls. Three _specimens of this interesting roach have been _taken,

two by

^{H. S. Barber on}

May

^{23 of the}

present year

and

one

by

^{R. C.}

Shannon

on

May

^{31. These}

roacheswere takenindecayed pinelogs. This_speciesseemstobe very ^{local in occurrence} but _{enjoys a} wide distribution, ranging from the Atlantic to the Pacific

and

from

Canada

on the _north, south to about the 34th _parallel, the furthest southern _record,

I believe, being

Rome,

Georgia.

Another insect not at all

common

ⁱⁿ the _regions surrounding Washington ^is Melanoplus ^{collinus Scudder.}

Numbers

of both sexes of this grasshopper were taken at Great _{Falls, Virginia,} on September12, 1912. It occurredin

some numbers

inthe open

woods

_just below the _picnic grounds ^{at the Falls.}

Melanoplus punctulatus Scudder occursin pine

woods and

has been taken but once

by me

in the _District, a _single male near the upper ^{reservoir north of} Georgetown.

A

male

was

collected on Plummer's _Island, Md.,

by

Douglas

demons

on August

11, 1905

and

the _specieshas alsobeen takenat FallsChurch, ^Va.

Museum

of Comparative ^Zool- ogy has kindly examined _specimens of the

Myriopod

^{from Huin-}

was

receivedafterthe

number had

_goneto_press.

He

writ <>

that the specimens ^are

immature and

cannot be _positively de- termined _{but belong} to the leptodesmid genus Chonaphe

and

are

probably ^C. armata _(Harger.)
