2IO NORTH AMERICAN BLATTIDAE 



broadly rounding to caudal margin, which is straight, transverse, 

 with latero-caudal angles rather sharply rounded, surface micro- 

 scopically pilose. Mesonotum and metanotum of female with 

 latero-caudal angles weakly acute-angulate produced, with apices 

 broadly rounded; entire dorsal surface microscopically pilose. 

 Tegmlna and wings fully developed in male, absent in female. 

 Tegmina pilose, with marginal and scapular fields very narrow, 

 veins and diagonal channel distinct, discoldal sectors oblique. 

 Cerci of male elongate, with distinct joints, tapering to the apical 

 joint, which is aciculate; of female short, submonolithiform, taper- 

 ing to the acute apex. Subgenital plate of female valvular, with 

 bases of valves straight, convergent from the distal margin of the 

 plate to their acute-angulate juncture. Limbs very slender in 

 male, somewhat heavier in female. Femora unarmed, except for 

 a delicate genicular spine on median and caudal femora. The 

 caudal margin of the cephalic femora not supplied. In the male, 

 with an exceedingly heavy, mesal, projecting tooth, followed by 

 other smaller teeth, as characteristic for that sex in Latindia s. s. 

 Tarsi elongate and slender, without pulvilli. Arolia minute, 

 vestigial or absent.

This species shows close relationship to C. mexicanus (Saus- 

 sure),^" differing from that Insect in the smaller size, proportion- 

 ately less ample tegmina and wings and the once forked or un- 

 branched median vein of the wings. 



Characters of Male. — (Brownsville, Texas.) Size small, intermediate between 

 that of the smaller C. delicatulus and the larger C. mexicanus. Head with inter-

There is little doubt but that tolteca is an absolute synonym of this species, as admitted 

 possible, by the original authors. Their hypothesis, as to the sex of the type, clearly 

 amounts to no more than a wild guess.
