 of the face below antennce yellow, the lateral face marks and the supraclypeal mark 

 extending half way between the antennne and anterior ocellus ; strongly punctured, 

 the punctures adjoining on the front and vertex, punctures on the yellow lateral face 

 marks not adjoining and not so deep, frontal carina terminating above with the supra-

 grooved ; dorsulum with punctures like those on the head adjoining separated in the

 raetathorax coarsely punctured like the dorsulum, shining, enclosure dull, appearing 

 transversely striate, black, with two yellow spots one on each side; wings, first and 

 second, recurrent nervures entering the second and third submarginal cells respectively 

 a little farther from the first and second transverse cubiti than the length of the petiole 

 of the second submarginal cell, stigma testaceous, nervures brown, marginal cell and 

 apex of the wings infuscated ; legs yellow, basal half of four anterior femora and 

 apical half of posterior femora more or less brown to black, posterior tibire posteriorly 

 and tarsi brownish.

 by a black line and nearly extending to the top of the eye ; supraclypeal mark repre- 

 sented by two yellow spots ; face and clypeus dull the punctures shallow ; head with 

 nearly adjoining well defined shallow punctures ; eyes black and gray ; third joint of
