beginning of the apical one-third of the elytra. This blotch is 

 deeply bi-emarginate on its lateral margins and also emarginate 

 on its hindmargin. The emargination of the hindmargin is in 

 some specimens not deeper than those of the lateral margins, but 

 in other examples is very much deeper (in one even becoming a 

 long cleft extending two-thirds of the distance up the middle of 

 the blotch towards its front margin). This species differs from 

 C. upsilon as follows : form evidently more elongate and parallel ; 

 elytral markings quite different; clypeus and basal part of 

 antennae densely pilose ; prothorax much more pilose and with 

 less straight sides ; head considerably more convex between the 

 eyes ; elytra much less distinctly punctured ; labrum of female 

 tri-dentate in front. The female examples before me have the 

 apex of the suture distinctly spiniform, but in the unique male 

 there is no trace of a spine ; perhaps this is an abnormal speci- 

 men.

 This species is distinguishable among its allies by the abso- 

 lutely flat interstices of its elytra (the puncturation of which is 

 very fine and runs partly in two, partly in three, longitudinal 

 rows) and the strong uniform transverse wrinkling of the disc of 

 its pronotum. Compared with G. longipenne, Germ., of same 

 sex, it is of somewhat similar, but a little wider form ; its 

 labrum is much more obtuse at the apex ; its head does not differ 

 much except in the upper surface being conspicuously strigate 

 transversely ; its ligula is of entirely different form ; its pro- 

 thorax does not differ much in outline except in the middle part 

 of the front margin being more prominent ; the marginal flatten- 

 ing of the pronotum is much wider and better defined (even more
