The series of this species, which presents a combina- 

 tion of characters forbidding its collocation in any de- 

 scribed genus, consists, unfortunately, of females only. 

 The only genus it seems to resemble is Axesti)i>(s (Lee), 

 which, however, has 12-jointed antenna3 and other points 

 of difference.

The species for which the institution of this genus is 

 necessary does not lit into any of the numerous 

 " Groupes " instituted by Lacordaire for the Ccramhij- 

 cidce. Its fades is very nearly that of Ilemilissa of the 

 " Piezocerides" group, but it is deficient in the essential 

 structural characters of that form. The eyes are not 

 very unlike those of Asemum, but they are still narrower 

 and more convex, and they are reniform, though the 

 lower lobe is not wider than the upper, and is situated
