4* Indian Museum Notes. [Vol, VI. 



rufous pubescence, very short and sparse, denser near the anterior 

 edge of the pronotum and, in the 6% on the apical declivity of the 

 elytra, which often appears as if covered with a sort of yellowish 

 pulverescence. The pubescence on the scutellum dense, often 

 appearing as a well-marked light coloured blotch. Ventral pubescence 

 less short and more abundant than that of the upper part of the 

 body. Head large. Forehead more or less punctuate, or rasp-like. 

 Epistome densely pubescent, especially in the ? , with a fine longitu- 

 dinal keel in the middle. Labrum pubescent above. Sculpture of 

 the posterior surface of the pronotum fairly large, rasp-like, consisting 

 of scaloidal tubercles more prominent in the $ , Posterior angles 

 of the prothorax generally straight, pointed, rarely rounded at times 

 slightly lobed in the ? . Dorsal punctuation of the elytra well 

 marked and dense and arranged in regular series. 



c? . Apical declivity is usually less strongly and less densely 

 punctuate than the back" of the elytra and has, on each side, a marginal 

 subcylindrical apophysis, fairly thick, and obliquely truncate at the 

 top and pointed on the inside. The lower border of the declivity 

 plain, shining and detached laterally from the edge of the elytra. 

 Joints 2-4 of the anterior tarsi furnished with long hairs beneath. 



? . Eyes larger, apical declivity as strongly or more strongly 

 punctuate than the dorsal region, the punctuation being very closely 

 serried; marginal processes replaced each by a callosity; the lower 

 border not laterally distinct from the edge of the elytra. Anterior 

 tarsus without long hairs beneath. 



This species is fairly variable as far as the sculpture and dorsal 

 pubescence are concerned, also with regard to the form of the 

 anterior indentation and the posterior angles of the prothorax and 

 above all as to the shape of the elytral apophyses of the <? , whose 

 position with reference to the suture also varies to a certain extent. 



H . hamatipennis forms the transitional form between the 

 present genus and the next one, the Bostrichopsis. The S has in 

 fact many of the characters of the heteromorphous Bostrichopsis $ : 

 cephalic profile, frontal-clypeal suture, clypeal pubescence, prothoracic 

 horns, and the visibility of the pleurites of the last apparent segment 

 of the abdomen.
