more conspicuous. It differs completely from G. Mastersi m 

 having the mesosternal process long and prominent, and also is 

 very much less distinctly punctulate than that species (except on 

 the clypeus of the female) ; the clypeus of the male diff"ers as 

 mentioned above ; the lateral edging of the prothorax is continued 

 from the hind angles only a very short distance along the base, and 

 the base is less (in the male before me not at all, in the female 

 scarcely) emarginate in the middle ; in both sexes of 0. Mastersi 

 it is evidently though slightly emarginate ; the elytra of C. Frenchi 

 are not striated but bear some longitudinal scratch-like lines, — 

 more conspicuous in the female than in the male, — the punctura- 

 tion in the former sex being not quite so obsolete as in the latter.

Closely allied to A. calvns, Blackb., from which it diff'ers as 

 follows : the club of the antenme in the male is very much shorter 

 (in A. cnlvus it is about twice as long as all the other joints 

 together) ; the prothorax and scutellura are much less strongly 

 punctured and the former is differently .shaped, its greatest width 

 being scarcely more than half again its length down the middle, 

 the sides being somewhat parallel in the hinder half whence they 

 converge arcuately to the front, and the base being much less 

 strongly bisinuate (so that its middle part appears to be less lobed 

 hindward) and ])eing scarcely or not margined (in calvns the 

 margin is well defined). The bunches or fringes of hairs over the 

 scutellum and pygidium are much less dense (possibly this might
