Lingua (PI. IX.. fig. t>, 1> moderate, subcorneal, truncate and quadridentate at 



the apex. 

 Pronotum moderate, transverse, and rounded at the sides. 

 Elytra short, abruptly truncate, with the epipleura distinct and broad. 

 Wings not examined. 

 Abdon en elongate, with either four or five segments exposed and equal in length, 



apical segment entire and pointed. 

 Prothorax (PI. IX., tig. 2, a) with the prosternum rather large ; episterna minute; 



epimera large, enclosing the coxa] cavities behind ; coxal cavities rounded, and 



nearly contingent. 

 Meso8ternum (PI. IX., fig. 2, d) large, not carinated ; episterna large, suboblong; 



epimera rery large, extending broadlj to the coxal cavities ; coxal cavities rather 



lar;_:e, transversely oval, nearly contingent. 

 Metasternum (PI. IX., tig. 2, gi rather large, transversely oblong, extending to the 



sides of the body, with the posterior margin between the coxa; straight ; 



episterna entirely covered by the elytra : epimera minutely and triangularly 



intlexed beyond the metasternum. 

 Venter comj)osed of seven segments, of which the basal is rather the longest, and 



the apical entire and rather pointed, 

 Legs anterior slender, trochanters small, trigonal ; femora simple ; tibia? long and 



slender; tarsi three-jointed ; 1 moderate; 2 much smaller than the first; 3 



very long and slender ; claws feeble, slightly curved. 

 intermediate like the anterior, but with the tibiae slightly dilated towards the apex. 

 posterior (PI. IX., fig. 8) rather longer than the preceding, trochanters moderate, 



claviform ; femora simple, rather robust ; tibiae slightly dilated towards the apex 



with the inner margin remotely serrated ; tarsi like the anterior. 

 Coxa- anterior rounded, nearly contingent. 

 intermediate oval, nearly contingent. 

 posterior small, prominent, not laminated, and widely distant. 



In the shortness of its elytra and length of its abdomen this genus resembles 

 Ptinella, but in other respects is totally different. Its principal diagnostic charac- 

 ters consist in the hardness of its integument, seven ventral segments, and the 

 absence of laminae on the posterior coxa?. 



Championella nubigena.
