166 REVISION OF THE GENUS HETERONTX^ 



more than half as wide ns the lateral ones, rather longer than these, 

 and very strongly convex ; clypeal suture gently arched ; clypeus 

 unusually convex, — or sub-gibbous, very distinct from hinder part 

 of head. Prothorax about f again as wide as long ; widest close to 

 the base ; its base nearly ^ again as wide as its front which is 

 moderately emarginate with the angles fairly sharp and produced ; 

 its sides gently arched, and forming (viewed from above) feebly 

 defined angles with the base which is moderately bisinuate and lobed 

 hindward in the middle. Elytra with more or less feeble indica- 

 tions of striation (most examples showing at least traces of a sutural 

 stria) ; their transverse wrinkling very strongly (at least in some 

 lights) defined; lateral fringe normal ; membranous apex moderate. 

 The punctu ration of the upper surface is about as close in all 

 parts as (except the head where it is closer than) in H. gracilij)es, 

 but is a little finer, more squamose, and less strongly impressed. 

 The hind coxae are as nearly as possible the same length as the 

 external margin of the 2nd ventral segment, and are very much 

 shorter than the metasternum ; like it they are rather coarsely 

 punctulate, — sparsely in the middle, more closely at the sides- 

 The puncturation of the ventral segments does not differ much 

 from that of the metasternum except in being a little finer and 

 nearly uniform all across. The ventral series consist of rather 

 stout hairs and are well defined, but very slender and feeble in the 

 middle. The hind femora are not very much wider than the inter- 

 mediate and have their inner apical angle fairly prominent but not 

 sharp; all the teeth of the anterior tibiae are sharp and strong, — 

 the uppermost about half the size of the second.
