to be in reality when inspected from the side ; the base is scarcely 

 bisinuate but is rather decidedly lobed hind ward ; the punctiir- 

 ation is spaced so tliat scarcely 20 punctures of average distance 

 could be placed in a line down the middle. The elytra are 

 punctured not very differently from the prothorax but squamosely 

 aiid a trifle more coarsely, whence the puncturation appears a 

 little closer ; they bear scarcely a trace of striation except the 

 sutural stride ; the transverse wrinkling is somewhat conspicuous 

 from some points of view and their lateral fringe is normal ; the 

 apical membrane is verv strongly developed projecting hindward 

 from the apex of the elytra in a wide riband-like band which is 

 widest at the suture where it projects almost as far as the length 

 of one of the hind claws. The hind coxae are decidedly (but not 

 much) shorter than the metasternum, both being punctured some- 

 what coarsely, rather closely at the sides and much more sparingly 

 towards the middle, the former having a small well-defined \sevi- 

 gate antero-internal space. The puncturation of the ventral seg- 

 ments is lightly impressed and sparse, but fairly even ; the ventral 

 series consist of fine hairs and are very inconspicuous. The hind 

 femora are not much wider than the intermediate, their inner 

 apical angle being feeble. The teeth of the anterior tibiae are 

 robust and sharp, the uppermost less than half as large as the 

 second. The inner apex of the basal piece of the hind claws is 

 scarcely produced in a tooth. 



The exceptional development of the apical membrane of the 

 elytra is quite invariable in the moderately numerous series 

 before me.
