 interval. The rostrum is strictly typical of the genus.

This species is easy of recognition. The head is somewhat 

 scooped out at the base of the i-ostrum. The thorax is covei-ed 

 with large rugose tubercles. The elytra are rather rugose and 

 have a " costa " on each side near the suture — -continuous near 

 the base, but becoming tubercular near the apex : on each side of 

 the " costa " there is a line of two or three distant glossy tuber- 

 cles. The elytra are also slightly mucronate.

 irregulariter foveatis.

This insect is of a deep black, The rostrum is much like 

 that of a Psalidura. The forehead is wrinkled. The thorax, 

 which is broadly lobed in front, is very little wider than the 

 head, and is covered with flattish hemispherical tubercles with a 

 bai'c spot about the middle. The elytra are not wider than the 

 thorax, and are rather convex and flat-sided. Their sculpture 

 consists of rows of irregular fovese (each with a double row of 

 coarse punctures), separated by slightly elevated irregular ridges,
