4S [July, is:.-.. 



This species agrees with none of the four genera of the group 

 Anopl oderviides, according to Lacordaire's definitions ; it partakes of 

 the characters of all of them, with some specialities of its own ; and, as 

 it is probable all four will eventually be combined into one, I prefer 

 referring the insect to the typical genus to creating a new one. The 

 eyes are rather finely granulated, widely distant and sharply emargi- 

 nated. The forehead is concave, narrowed to the epistome, which is 

 vertical and even concave on its front face. The large tooth near the 

 base of the left mandible exists in both sexes, though much longer in 

 the ^ . The palpi have oval terminal joints. The hind part of the 

 head is thick and convex. The thorax is twice the width of the 

 head ; transverse-quadrate, but with regularly rounded sides ; the 

 somewhat explanated lateral margin terminates in a rectangle iiear the 

 base, where the thorax is suddenly constricted ; the surface in both 

 sexes is covered with circular punctures, which coalesce in irregular 

 patches, leaving irregular and almost impunctate spaces. The elytra are 

 uniformly and coarsely sub-confluent punctate. The tibife are covered 

 with sharp tubercles and denticulations, and the external side of their 

 dilated apices is prolonged into a long tooth ; the tai'si are linear, 

 about as long as the tibifp, densely bristly beneath, with the fourth 

 joint well developed and of the same shape as the others, though smaller. 

 The hind trochanters of the male are prolonged as sharp spines, half 

 as long as the femora. 



The antennae of the ^ are four-fifths the length of the body ; 

 joints 1 to 3 are glabi'ous and shining, the rest are densely and mi- 

 nutely porous and opaque ; the 3rd joint is of about the same length 

 as the 4th, but is clavate and simple, whilst the 4th is greatly prolonged 

 at its outer apex like the 5th to 10th. In the ? the antenna" are ex- 

 tremely short, with shining moniliform joints, the 3rd and 1 Ith the 

 longest and nearly equal.
