120 THE CANADIAN ENTOMOLOGIST. 



Subgenus Hesperocorixa, nov. subgen. 



This has the characters of Arctocorixa. Wallengr. (sens, lat.), but 

 differs by the non-roslrate pronotum and tegmina and the non-lineate 

 pronotum. From Agraptocorixa, Kirk., it differs by the total absence 

 of black hairs, the surface being polished. From Corixa^ Geoffr., it differs 

 by the o asymmetry being on the other side, and by the absence of 

 lineations. It may prove a good genus. 



3. H. Brimleyi, sp. nov. — Head, fore legs, middle femora and claws, 

 hind coxa?, etc., pale yellow. Eyes gray-brown. Pronotum and tegmina 

 pale ferruginous, sometimes suffused with sanguineous, base of clavus and 

 a large spot near apex of corium blackish-brown. Sterna, meso- and 

 metanotum and abdomen black or blackish, pleurites and apical segment 

 of abdomen yellowish, partly suffused with red. Middle tibiae and hind 

 femora and tibi?e sanguineous, the fringe on the latter golden-brown. 



Pronotum short, very transverse, polished, very faintly rostrate, if at 

 all, obsolescently keeled percurrently. Tegmina smooth and polished, 

 obsolescently punctured, non-lineate, membrane angularly rounded at the 

 apex. Middle cibiae one-eighth longer than the tarsi, which are equal to 

 the mutually equally long ciaws. 



^ . — Face slightly flattened in the middle, scarcely excavated. Pala 

 cultrate, with a closely-set row of about 28 pegs. Strigil rather large, 

 oblong, oval, with five subeven rows. < 



$ . — Pala elongate cultrate. 



Length, 9 mill. Hab.: Raleigh, N. C. (Brimley). 



This is very distinct from any other American species known to me.
