This species is very close to H. capillatus, Macl., and is 

 difficult to distinguish from it by characters suitable for 

 tabulation. The four specimens of it before me are notably 

 lighter in colour (perhaps variable), with the frons more 

 coarsely rugulose, the punctures of the pronotum larger and 

 less close (in capillatus there are about 22 in the length of the 

 segment), the pronotum less convex viewed from the side, the 

 hind coxae less closely punctulate, the hind femora consider- 

 ably more dilated.

 antice late nonnihil emarginato ; labro clypei planum

An extremely isolated species of unusually narrow and 

 elongate form. The hind coxae, though not very much shorter 

 than the metasternum, leave a wide strip of the 1st ventral 

 segment exposed.

H. submetallicus, Blackb. When I described this species 



I expressed some doubt as to its being really distinct from 



H. Lindi, Blackb. Since that time I have seen several more 



specimens of both forms, and find that the colour distinctions
