shorter and narrower than those that follow, the last shortly ovate, 

 scarcely longer than the preceding ; the thorax much narrower 

 than the elytra, a little broader than long, with the sides lightly 

 rounded, behind subsinuate, veiy densely punctulated, clothed 

 with a dense yellow silky pubescence ; elytra oblong ovate, very 

 closely i)unctate, but evidently impressed with a sutural stria ; 

 thighs pitchy black. 



" Very rare in the Alps. (At the Gemmi near the Dau- 

 bensee*.") 



The above description can I think be referred to nothing but 

 tristis ; the greater relative length of the thorax, which M. Heer 

 specifies as the chief distinction, being doubtless either the result 

 of variation in the length of the elytra, or one of the variations to 

 which this species is subject. The next variety, which I refer to 

 the same species, shows a much greater variation in the relative 

 dimensions and proportions of the thorax. 



Neither ]M. Ki-aatz nor myself have seen authentic examples of 

 the above species, but ^I. lloscnhauer speaks of it {supra) as if he 

 was familiar with it, and says that but for the colour of the last 

 segments of the abdomen in his abduminalis, he would have 

 referred that species to montivagus. M. Kraatz having ascer- 

 tained aliunde that abdominalis was an immature specimen of 

 tristis, differing only in the colour of these segments, it follows 

 that montivagus is what the description would lead us to suppose, 

 viz. a variety or synonym of tristis.

Somewhat of the form of the C, nigrita, but 

 larger, and especially broader. Black-brown. 

 The antennee are not quite so long as the head 

 and thorax, gradually slightly thickened, to- 

 wards the point reddish brown, the last joint blackish. The 

 head and thorax are densely punctured and granulated exactly 

 as in C. tristis, clothed with close-lying yellow hairs. The latter 

 is considerably broader than the elytra, more than one-half
