SPHENOSTETHUS, Mud. 
This genus is also represented by a single species, a shining black 
insect which by its tapering form suggests the family L/azerid@. The head 
is small, prothorax large, trapezoidal, smooth, somewhat convex, very 
obtusely toothed near base; elytra also black, tapering, dehiscent, punct- 
ured, tip finely serrate, margin and suture obtusely spinose. ‘The an- 
tennze are less than 2 the length of body, slender, slightly compressed 
and serrate.

ELATEROPSIS, “hv. 
This genus closely allied to preceding is again represented by a 
single species which like the preceding is a shining black insect but 
with a greenish tinge. It resembles .S. Zas/ec in most points and is 
distinguished therefrom by the sides of thorax being crenulate and acute- 
ly toothed near the middle. The tip of the elytra is crenulate and they 
are not dehiscent. Antenne 2 length of body slender and compressed.

SUB FAMILY CERAMBYCIN 4. 
This subfamily is defined by the following characters, viz: prothorax 
not margined, labrum separate from the front, front tibie not obliquely 
sulcate, palpi never acute at tip, antennze always pubescent.
