120 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



Hormetica and allied genera, showing a Blaberine fades, and 

 lastly that in which belongs Para?iauphoeta, showing striking 

 approach toward the Panesthinae. 



Still other divisions are represented in the present subfamily, 

 but at present insufficient material is before us to assign these 

 properly. 



COLAPTEROBLATTA-'- new genus 



The simple type of pronotum in the present genus is remarkable 

 in the present group, the majority of the forms of which have the 

 lateral wings of the pronotum deflexed and variously specialized.'** 



Nearest relationship is found in Porohlatta, also an American 

 genus, described on page 123, where these genera are compared. 



Genotype. — Colapteroblatta compsa new species. 



Description of Genus. — Form dissimilar in the sexes: male 

 elongate, rather broad, with dorsal surface of abdomen feebly 

 convex between the moderately raised lateral margins; female 

 less elongate, broad, with dorsal surface of abdomen evenly con- 

 vex. Head of male with interocular space broad and ocelli large 

 and sharply defined, of female with interocular space extremely 

 broad and ocelli small but distinct. Pronotum of male moder- 

 ately punctulate, with surface very weakly convex except above 

 the head, where the convexity is more decided, and laterad where 

 the lateral wings are subdeplanate and feebly declivent, caudal 

 margin feebly convex with a median angvilation subobsolete; of 

 female moderately punctulate, with surface moderately convex, 

 the greatest convexity above the head (less than in male) and 

 declivent, unspecialized lateral wings (more strongly declivent 

 than in male), leaving the evenness of the general convexity little 

 disturbed. Tegmina of male delicate, very elongate and narrow, 

 extending much beyond apex of abdomen; of female heavily 

 chitinous, abbreviate. Wings of male fully developed; of female 

 minute, atrophied pads. Supra-anal plate of male bilobate, very 

 delicate; of female with distal margin convex but showing traces 

 of bilobation, heavily chitinous. Subgenital plate of male of 

 characteristic Blaberine type (variously developed also in the 

 Epilamprhiae and Panchlorinae) ; of female simple, ample, convex 

 and fitting closely all of ventral portion of abdomen l)eyond fifth
