Maris (1) tarsorum anticorum articulis basalibus 4 sat elongatis, 

 1" 2" fere duplo longiori et latiori, subtus baud sulcato ; 

 tibiis posticis intus pilis aureis seriatim vestitis, elytris 

 sparsim leviter punctulatis, hie illic longitiidinaliter undatim 

 rugatis. 



Feminse {1) tarsorum anticorum articulis basalibus 4 brevibus 

 subsequalibus, tibiis posticis intus baud pilosis, elytris baud 

 punctulatis. 



The length of the prothorax down the middle is 1| lines, while 

 the distance between the apices of the anterior and posterior angles 

 is 2? lines (vix) and the middle of a line joining the apices of the 

 two front angles would be about -^-^ line distant from the middle 

 of the front of the prothorax. The gular sulcus is narrower and 

 less profound than in the preceding two species, the submentum 

 being scarcely different from that of H. loita. The presternum is 

 not prominent in front, its hinder part being more or less flattened 

 down the middle with a strong stria on either side outside which 

 the edge is turned up (more strongly in one example than in the 

 other), — the hinder extremity not bifid. The front and inter- 

 mediate coxae are distinctly punctulate. The row of punctures 

 close to the margin of the elytra is well marked in one of the 

 examples before me and can be traced almost to the apex ; in the 

 other example it is much feebler (more so on one elytron than on 

 the other). The lateral gutter of the prothorax is well defined ; 

 from a certain point of view a flat gutter is apparent much wider 

 than the thickened margin of the prothorax and well limited ; that 

 of the elytra is reduced to a mere stria-like impression within the 

 narrow thickened edge of the elytron but is a trifle wider near 

 the apex. 



I feel scarcely any doubt of the two examples before me being 

 male and female of one species. They were taken under stones 

 close to each other and only differ inter se as specified above.
