BY THE REV. T. BLACKBURN. 141 



Section III. — Labrum turned upward and overtopping the plane 

 of the clypeus. (By far the largest Section, — subdivided as 

 follows) : — 



Group 1. — Antennae 8-jointed. 



Subgroup 1.— Claws bifid. {Ic. p. 1359). 



Subgroup 2. — Claws appendiculate. (The subject of the 

 present memoir.) 



Group 2. — Antenna3 9-jointed. (To be dealt with in next 

 memoir ) 



Tabulation of the species dealt with in the present memoir : — 



A. Hind coxse at their longest not (or 

 scarcely^) shorter than the suture 

 between the metasternum and its 

 episterna. 

 B. Elytra furnished with fine short ad- 

 pressed pubescence. 

 C. Elytra not granuliferous. 



D. Puncturation of hind coxae 

 rather close on external half 



of the surface (size large) normalis, Blackb. 



DD. Puncturation of hind coxae at 

 its closest only very sparing 



(size very small) brevicornis, Blackb. 



CC. Elytra granuliferous granulifer, Blackb. 



BB. Elytra bearing only long isolated 

 more or less erect hairs (as in H. 

 fulvohirtus, Blackb.) nasutus, Blackb. 



*I have added this saving clause, — but I find that in the 4 species actually 

 included under this heading the metasternum is in no case noticeably longer 

 than the hind coxae, although measurement in two of them proves that it is 

 very slightly so.
