" 3. C pubescens, EecUenbacher. This is the smallest of the three species : it is 

 disliuguished by the upper parts being densely clothed with pale ashy pubescence 

 (hence the insect has a somewhat dull appearance) ; the colour is black, but the apex 

 of the elytra and the abdomen are more or less pitchy ; the pale colour on the sides of 

 the thorax is more extended than in the preceding species, and the legs are entirely of 

 a very pale testaceous colour ; the antennag are also pale, with the exception of the 

 club, which is somewhat tinted with brown. 



"The form of the head likewise differs in these insects; and with regard to the 

 last-mentioned species, I would call attention to the larger size of the eye, when com- 

 pared wilh the preceding : here it occupies nearly the whole of the lateral lobe of the 

 head, which is marked off by the antennal notch."
