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 Aptesis. 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. 9 - Dull black; head large, broader than the tho- 

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

 ternal 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 tegulae fulvous. 

 Length 4 mm.
