Btidde-Lund suggests that this species may be identical with

Inasmuch as the specific name 8pedo9U8 is applied by Dana to another

 name California*. 



Bod}' ovate, very convex, smooth and shining. Second antenna?

 cle straight, cylindrical, very long; flagellum with tho articles unequal

 segments of the thorax with the posterior margin slightly sinuate on 

 both sides, the three last segments very slightly sinuate. The epirnera

 posterior angles of the first segment straight, roundly rectangular, 

 with the margin sulcate; those of the second, third, fourth, and fifth 

 segments gradually less widely rounded; those of the sixth and seventh
