tarsal proportions, to a much less degree in form of pronotum, due 

 to the more hooded type developed in this sex of Coldpteroblatta, 

 while in Litopeltis the tegmina are suhquadrate. 



Genotype: Litopeltis bispinosa [Calolampra bispi)iosa] (Saus- 

 sure). 



Generic Description. — Size rather small for the group; form dis- 

 similar in the sexes, male elongate, rather broad with dorsal surface 

 of abdomen showing scarcely any convexit}', female less elongate, 

 broad, with dorsal surface of abdomen evenly convex. Surface of 

 head and pronotum polished, microscopically and not thickly 

 impresso-punctate. Interocular space of male broad, of female 

 broader, in neither sex equal to width between antennal sockets. 

 Ocelli represented by large, poorly defined spots in male; sim- 

 ilar but smaller in female. 



Pronotum with disk moderately convex, lateral wings strongly 

 dcclivent, unspecialized; cephalic margin of pronotum showing 

 weak truncation and caudal margin weakly obtuse-angulatc 

 produced with apex broadly rounded. Tegmina of male elongate, 

 extending well beyond apex of abdomen; of female hea\ily 

 chitinous, subquadrate, with sutural margins overlapping. Wings 

 of male fully developed, of female small oval atrophied pads. 

 Supra-anal plate of male very delicate, showing only a trace of 

 bilobation; of female hea\ily chitinous with distal margin convex. 



Limbs moderately heavy in male, very slightly more so in 

 female. \>ntro-cephalic margin of cephalic femora supplied with 

 a fringe of chaetiform hairs, terminating distad in a single heavy, 

 much reduced spine; \entro-caudal margin armed distad with 

 (one^^* and one distal) heavy spines. Ventro-cephalic margin of 

 median and caudal femora armed with (one or two and one distal) 

 heavy, reduced spines. \'entro-caudal margin of median femora 

 armed with (three or four, usually four, and one distal) heavy 

 spines, of caudal femora with (three or four, usually three, and no 

 distal) heavy spines. I'our proximal tarsal joints with \entral 

 surfaces unarmed, occupied by large pulvilli which are bluntly 

 angulate produced distad, that of metatarsus linear in proximal 

 portion. Moderate arolia present between the delicate tarsal 

 claws. 



'"^ Yen- rarely this spine is absent.
