32 ENTOMOLOGICAL NEWS. [January, 



not properly expanded when the insect issued from the pupa case, 

 but a closer examination showed both to be untrue. They prove 

 to be naturally well formed, what there is of them, and are but 

 dwarfed, abortive and useless. 



Upon investigation I find the species is undescribed and be- 

 longs to the genus Ap/esi's. In our fauna there is only one other 

 species known of these subwinged Ichneumonids, and that seems 

 to be rare. While they probably are not as common as the en- 

 tirely wingless species, they no doubt are made more rare by col- 

 lectors discarding them with the injured and imperfect material 

 as a part of it. The wingless forms are so distinctly different 

 that they are seldom overlooked, but the partially winged ones 

 are liable to deceive a person, and collectors should be on the 

 watch for such forms. 



I append the following description: 



Aptesis major n. sp. Q. — Dull black; head large, broader than the tho- 

 rax, finely punctured; ocelli distinct, glassy; mandibles black, with ex- 

 tenicrt dull ferruginous spot; labial palpi black, maxillary palpi long, light 

 brown; antennae long filiform, the first three joints of the flagellum form- 

 ing fully one-third of the length, scape and first two joints of flagellum 

 rufous, remainder dark brown, except joints 4-8, which are white, except 

 a narrow stripe beneath; pro- and mesothorax shining, slightly punctured; 

 parapsidal grooves distinct; metathorax broad, quadrate, flat and gener- 

 ally sloping behind; smooth, except that it is densely and rather coarsely 

 punctured; scutellum and blunt tubercles on metathorax dull rufous; most 

 of femora and tibiae on posterior legs dusky; remainder of legs rufous, 

 except trochanters, which are much lighter; abdomen elliptical, finely 

 punctured; petiole smooth and flat above, margined, greatly expanded 

 near the tip; last half of third, the following segments and ovipositor 

 black, remaining segments rufous; ovipositor exserted nearly the length 

 of the abdomen; winglets reach nearly to the tip of the metathorax, ner- 

 vures developed to the stigma; base of nervures and tegulcC fulvous. 

 Length 4 mm.
