 above, and appears ajrain on tlie onter face, bnt diflnsed. snbconthient, 

 and. crossed by the pallid angulate incisures: inferior face red; <i:enicii- 

 lar an- black on both sides; hind tibiae red. with a siibbasal, narrow, 

 fuscous annulus. the spines black to their base, twelve in number in the 

 outer series. Kxtreuiity of the male abdomen roundly clavate and 

 upturned, the sui)raanal plate trian<jular and tolerably tlat, but with a 

 deep basal median sulcus reaching:: more than half way to the tip with 

 pretty hij^h and sharj) boundinj^' ridj^cs. fading* rvv-ally : furcula wholly 

 wanting; cerci stout, heavy, and incurved, narrowing considerably 

 toward the middle, then very rapi<lly expanding and furcate, the upi)er 

 lobe longer than the lower and more e«|Ual, well rounded ai)ically, 

 directed sharply upward, the lower triangular, bluntly pointed, and 

 turned but little downward, the apical nnirgin of the whole deeply and 

 angularly excised, .^^carcely surpassing the supraanal plate; infraeercal 

 plates just longer than the sui)raanal plate: subgenital plate moder- 

 ately narrow, the ' /: :^' it le and angularly elevated, scarcely i)ro-

This group is nearly related to the robustus series; the male prozona 

 is more or less distinctly longitudinal, and tlie interspace between the 

 mesosternal h>bt - of the same sex nearly or UKue than twice as long as 

 broad; the eyes are rather widely separated, and the frontal costa 

 broad and e<iual. The prosternal si)ine is i ather long and general'y 

 slightly retrorse. The tegmina are fully developed, at least as long as 

 the hind femora, without spots or, rarely, very feebly marmorate, but 

 sometimes with a light stri[>e dividing the dorsal and lateral faces and 

 extending acrc;;s the pronotum. The hind femora are longitudinally 

 striped on the outer %ce or iv marked, the hind tibiae usually red, 

 rarely purplish, with ten to thii'teen spines in the outer series. 



The srpraanal i)late is much as in the robustus series: the furcula is 

 present as small but coarse lobes, and the eerci are much as in the 

 robustus series, but less extravagantly developed; the subgenital plate 

 is longer than broad, generally morierjitely narrow, somewhat elevated 

 and sometimes tliickened ai)ically, hardly prolonged, and ^'' .»'ays entire. 



It comprises insects of a large or a very large size, with heavy bodies 

 and poor in flight. Five species are known, and among them they cover 

 our entne territo v, from Atlantic to Prc'tic and from Central Mexico 

 to the Saskatchewan and Hudson Bay. It comprises two of our com- 

 monest species.
