 the preceding, to which it appears to be most nearly allied. The great convexity oF the

Long. 



One specimen, San Diego, California. The antennae are longer than the head and tho- 

 rax, and strongly serrate : the hairs on the thorax are so disposed as to produce a Faint 

 longitudinal dark line From the basal depression on each side: the dorsal channel i- distinct 

 both at base and apex: the tibiae and tarsi are paler than the Femora. The general Form 

 is that of the male oF L. cylindriFormis.
