-J. Clypeus produced anteriorly, rather narrowly truncate at 

 the apex, with a longitudinal carina from the base to the apex, 

 punctured. Head rather large, strongly punctured, the antenna? 

 very short, a raised carina above the base of the antennae on each 

 side, the front between the antennae narrowly truncate. Pro- 

 thorax long and broad, as broad as the head, the sides parallel, 

 the anterior margin raised. The thorax finel}^ and densely punc- 

 tured, most finely on the prothorax; the scutellum triangular, 

 more sparsely punctured, with a very delicate longitudinal carina 

 from the base to the apex. Median segment smooth at the base, 

 very finely reticulate on the apical portion, rather short and 

 obliquely depressed to the apex. Abdomen shining, with close, 

 shallow punctures, the apical margins of the segments smooth. 

 Segments 2-4: with a faint depressed transverse line near the base 

 and a faint raised mark on each side near the apical margin. 

 Pygidium smooth and rounded at the apex. The first segment 

 beneath with an elevated longitudinal carina from the base, 

 ending in a tubercle at the base of the oblique, triangular, apical 

 truncation of the segment. Light chestnut-brown; the clypeus, 

 anterior margin of the piothorax and postscutellum yellowish; 

 antennae, except the scape, and the three apicaJ abdominal seg- 

 ments black. Wings hyaline, faintly iridescent, nervures fuscous,

(J. Clypeus very narrowly produced, usually with a median 



carina; antennae of moderate length, usually longer than the 



head and thorax without the median segment. Head rounded, 



the sides with rather long pubescence, not much lengthened and
