132 ENTOMOLOGICAL SOCIETY A NEW SPECIES OF ROPTRONIA.

132 ENTOMOLOGICAL SOCIETY A NEW SPECIES OF ROPTRONIA.

By WILLIAM ^H. ASHMEAD.

The _following new

_species ⁱⁿ the rare

genus Roptronia

Prov.

was taken by

^Prof.

H. Garman,

^{of the State}

College

^of

Ken

tucky, ^at

Lexington, Ky., and

after

whom

^{I take} _pleasure in

naming

^the species.

The

_genus, as originally described,

was _{placed by} Abbe Pro- vancher

in the

family Braconidce, but was subsequently removed by him

tothe

subfamily Helorince

^{in the}

Proctotrypidcz. From

the

imperfect

figure of the

venation given by Provancher, and

before I

had

seen a

specimen

^for

examination,

^I

was

inclined to

doubt

the correctness of this last

view

ofthe learned

Abbess, and placed

^the

genus

doubtfully

among

^{the aberrant}

group Pachy lommatince

in the Braconidae.

Since

_{that time,}

however,

^I

have

seen three representatives of the

genus, and

a careful

study

^of these

specimens convinces me

that

Provancher was

correct in

removing

^the

genus

^tothe Helorinae.

The venation

is

somewhat

similarto the

genus Monomachus Westw., and ^seems

^{to afford} a

connecting

^link

between

this

genus and

the

genus Proctotrypes

Latr.

Monomachus should

also

be placed with

the Helorinae.
