near]}" a.s deep as long, slightly declivent and considerably sinuate 

 posteriorly; lateral carina? of the female ver}^ dull but nearly persist- 

 ent, converging some^^•hat about the middle of the anterior third, at 

 which point the disk is cut by a distinct but narrow transverse sulcus, 

 in the male the lateral carina^ are scarcely indicated anterior of the 

 posterior half of the pronotum and are almost parallel, the disk in 

 this sex with the transverse sulcus scarcely noticable, forming a mere 

 line; median carina inconspicuously ■ resent only on the posterior 

 third of the pronotum in both sexes; disk almost flat for the entire 

 length in the female, in the male slightl}' flattened on the posterior 

 half or a little less, the anterior portion broadly rounded; anterior 

 and posterior margins subtruncate in both sexes. Legs moderately 

 long, the posterior femora three times, or almost three times, as long 

 as the pronotum, parallel in the apical half, the basal half much and 

 abrupth" ampliate and armed below on both margins with several 

 short, sharp, black spinules; anterior tibia* armed above on the outer

margin only with three spines, rarely with four. Elytra of the male 

 extending beyond the pronotum a distance equal to about one-half the 

 length of the pronotum, uniform in color; in the female the elytra 

 are mere lateral pads scarcel}" extending l)e3"ond the pronotum. Ab- 

 domen moderately plump, subcarinate,. the last dorsal segment in the 

 male broadly and roundly concave and flattened apically as in hermanl! ; 

 cerci of the female a])out four times as long as the basal l)readth, cylin- 

 drical and tapering nearly uniformly to an acute point, of the male 

 cylindrical at the base, somewhat depressed apically and acutely 

 pointed, furnished on the inner side with a triangular tooth as long as 

 the cereal width at that point, the lower margin of the tooth perpen- 

 dicular to the main body of the cercus and situated about the middle 

 of it (fig. 70). Ovipositor considerably longer than the posterior 

 femora and curved slightly downward (fig. 69), apically pointed, the tip 

 graiuilose.
