hexagonal median area. Abdomen as long as the thorax, the ventral 

 valve very large, plowshare-shaped, and projecting considerably beyond 

 the tip of the abdomen, the ovipositor long; plate of first segment about 

 twice as long as wide, with the sides parallel, the apical corners slightly 

 rounded, shagreened, and with a longitudinal median sulcus towards 

 apex; second and third segments nearly smooth, at the most feebty 

 shagreened, the second very short, about half the length of the third, 

 with oblique grooved lines at basal lateral margins, but so widely sepa 

 rated and so close to the lateral margins as to be easily overlooked ; fourth 

 segment a little shorter than the third, the fifth a little longer than the 

 fourth, the following very short. Wings hyaline, the costa and stigma 

 dark brown or fuscous, the internal veins hyaline, the areolet open be 

 hind, the inner margin of same being about half the length of the first 

 branch of the radius, while the submedian cell is one-half the length of 

 the discoidal cell longer than the median cell. 



The male agrees very well with the female, except in the usual sexual 

 differences, and in having the antennae much longer than the body, the 

 hind tibiae is yellow only at base, and the tarsi entirely black, while the 

 costas and stigma, except outer margin, and the postmarginal, are white, 

 the membranous lateral margins of the first segment being piceous.

In my forthcoming monograph of the North American Bra- 

 conidae, I have divided the genus Apanteles into five principal 

 sections, based upon characters derived from the metathorax, and 

 these again are separated into divisions based upon the shape of 

 the plate or shield on the first segment, and the length and sculp 

 ture of the following segments important characters entirely 

 overlooked by previous writers on the group, although offering 

 excellent characters for the separation and the ready identification 

 of species. 



The present species belongs to my Section I, and comes nearest 

 to A. carpatus Say and A. edwardsii Riley, but is quite dis 

 tinct from both, in color of legs, and in sculpture and relative 

 length of the abdominal segments.
