308 [Ai>ril 



with a central longitudinal carina, tolerably well defined; second and 

 third segments with a more or less blue reflection, the latter rather 

 broadly margined at tip, deeply emarginate in the middle and slightly 

 sinuate on the sides, before the apex a transverse row of twelve deep 

 punctures; venter concave, strongly tinged with blue. Length 4 — b\ 

 lines; expanse of wings 62 — 82 lines. 



Four specimens. Readily distinguished by the dull green color and
