anterior ocellus to between the antennae. Antennae about as 

 long as abdomen. Thorax finely and closely punctured, anterior 

 margin of pronotum straight and strongly raised; scutellum with 

 a depressed, transverse row of punctures at base. Median 

 segment rugulose. Abdomen elongate-fusiform, shining, with a 

 faintly impressed transverse line near base of segments 2-6. 

 Epipygium with curved striae at apex; hypopygium elongate- 

 triangular, with a short apical spine, basal angles prominent. 

 The legs in some specimens are almost entirely black and the 

 wings tinged with yellow. 



9. Head half as broad again as long, convex, rounded at 

 posterior angles, shining and sparsely punctured, with a longi- 

 tudinal sulcus between antennae. Thorax and median segment 

 very finely and rather closely punctured, pronotum almost 

 rectangular, much broader than long, the anterior margin straight, 

 with a few large setigerous punctures. Mesonotum small; median 

 segment obliquely truncate from mesonotum. Abdomen shining, 

 very sparsely punctured, third segment broadest; first segment 

 rather long and narrow at base, the apical margin raised and 

 three or four irregular transverse striae before it; second segment 

 with about twelve transverse carinae, including the raised apical 

 margin, those near apex the strongest and most regular. Pygi- 

 dium almost vertically truncate, fairly broad, sides almost 

 parallel, incised near apex leaving a spine on each side continuous 

 with lateral margin; surface of truncation longitudinally striated. 

 Fifth ventral segment coarsely longitudinally rugose. Black; 

 head and second abdominal segment fusco-ferruginous; antennae, 

 mandibles and legs ferruginous; a transverse band on first 

 abdominal segment near base, a spot on each side of second, a 

 narrowly interrupted transverse band on middle of third and 

 fourth, and two spots on each side of fifth segment yellow. 

 Length 11 mm.
