 Long. 2\ lin. 



A long thin species. The head dark, the parts of the mouth 

 and the antennae ferruginous ; the latter about the length of the 

 elytra, the eighth joint a little smaller than the ninth, the last 

 joint long and acuminate. The thorax is variable in form, 

 sometimes widest at the middle, as in fig. 1, sometimes widest a 

 little before the middle, as in fig. 2, and sometimes widest at the 

 ver^ front, as in fig. 3, but never widest behind-, sometimes a little

broader than long, and sometimes about equal in length and 

 breadth. The sides are rounded. In some e:^amples they are 

 semitransparent or paler than the centre (and are then known as 

 the var. angustatus). In others the edges are firm and con- 

 colorous (the variety castaneus). The posterior angles are nearly 

 right-angled, more or less obtuse. The upper side is very 

 densely and finely punctate in the males, less so in the females, 

 and in both covered with a thin pubescence. The elytra are 

 feebly striated, finely and densely punctate, with a fine pubes- 

 cence, sometimes rounded, sometimes acuminate at the apex, 

 sometimes wholly ferruginous, sometimes dark chestnut, paler 

 round the borders. The under side is brown, the edges of the 

 abdominal segments and sometimes the apex of the abdomen 

 reddish. The legs ferruginous. 



The trochanters and thighs of the hind legs are liable to con- 

 siderable variation in form in the males. The following varieties 

 are met with. 



1. The trochanters are simple, and the thighs have a fine 

 tooth below. 



2. The tl\ighs are simple, and the trochanters are armed with 

 a sharp spike. J dji* *f;::*a'jkj <
