 flagellum; dorsulum not strongly depressed anteriorly in the middle, 

 with exceeding fine and close punctures; scutellum shining, slightly 

 impressed; metanotum very finely granulated and with a tolerably 

 distinct, medial, impressed line extending from base to apex, the pos-

 which are however a little more distinct than in nigripennis; dorsu-

 than in preceding species, and with a distinct, medial, raised line, 

 extending from base to near apex, the posterior face laterally with
