yellow shining through; punctate, the punctures as if made 

 from behind, some disposed in striae, of which depressed traces 

 are seen. Under side and legs green, with a faint coppery 

 tinge in certain lights, particularly along the margins of the 

 segments of the abdomen ; pubescence on posterior sides 

 of breast and edges of thighs not so dense as in preceding 

 species ; mesosternal projection and middle of breast with 

 nearly the same markings as last species, but stouter and not 

 punctate. I have only received female specimens with the tarsi 

 perfect. They have the exterior claw in each tarsus bifurcate, 

 as is the character of the claws of the female in this genus.
