Remark. The species varies considerably, in some specimens the pale 

 borders of the tergites are broad, in. others narrow, and the legs vary in 

 colour from castaneous to testaceous. 



Genus Desmo&osteria HOT. 



Allied to Zonioploca STAL, but the angles of none of the abdominal 

 tergites backwardly produced. Lateral margins of the pronotum incrassated. 

 Tegminal rudiments absent. Dorsal surface punctate or smooth. Supra- 

 anal lamina (S) quadrate, margins entire, (?) trigonal, cucullate. Cerci 

 short, flattened. Posterior metatarsus very short, not spined beneath. 



This genus stands in the same relation to Zonioploca that Anamesia 

 does to Cosmozosteria.
