This Braconid genus belongs to Wesmael's Polymorphes, and the species described below to Haliday's subgenus Meteorus, which is distinguished from the other genera or subgenera with Petiolated abdomen, by the anterior wing having three contiguous cubital cells.

1. Perilitus Niveitarsis. N. sp.––♂ ♀.––Ferruginous, shining; cheeks, sides of thorax and apex of abdomen thinly clothed with a short, whitish, somewhat pruinose pubescence; face and mouth pale ferruginous; palpi whitish; occiput and space enclosed by ocelli, blackish; antennae entirely dark fuscous; prothorax and sutures of mesothorax blackish; metathorax rounded, reticulated and with a trarsverse arcuate carina before the middle; tegulae Pale yellow; wings hyaline, iridescent.

when the descriptions of these species were prepared, I had forgotten that species had previously been described in Europe as G. juglandiella and H. evonymella. I have not seen these European species nor even any description of them, and possibly my species may prove to be the same. At any rate the names are so nearly the same as to necessitate a change of those, my species, and I therefore name them respectively G. juglandisnigrella and H. orbimaculella.

This species in most respects is so like C. M. proteus, that I had set it by as another variety; but upon further consideration I am induced to give it as a distinct, sincc it differs not only in colour but in the form and sculpture of the prothorax and other parts.
