Body much elongated and slender. Head slightly longer than broad, 

 broadest at the posterior margin of the eyes, behind which the head is 

 somewhat strongly contracted ; eyes pretty large, not very prominent. 

 Antennae a little more than half as long as the body, very slender ; surface 

 of head not very coarsely but very considerably granulate, with a tend- 

 ency toward a transverse disposition of the granules. Thorax subquad- 

 rate, scarcely narrower apically than basally, at the apex as broad as the 

 head, including the eyes; the lateral angles of the front somewhat rounded ; 

 surface like that of the head granulate, equally fine throughout, with no 

 distinction between the anterior and posterior portions. Hind femora very 

 long, gradually enlarging from base to apex, but scarcely stouter at the 

 broadest than the middle femora, almost as long as the antennas. Head 

 and thorax piceous, legs dusky fuliginous.

 half as long as the body, or a little more than that, moderately slender, the 

 second and third joints a little larger apically than at the base, the last joint 

 gently incrassated and fusiform. Thorax subquadrate, a little broader than 

 long, like the head granulate equally throughout, with no distinction 

 between the anterior and posterior portions. All the femora subequal, the 

 hind femora very much shorter than the antennae. Head and thorax pice-
