324 ENTOMOLOGICAL NEWS. [July, '17 



width of one eye; about 8 setae on each side of the front; four or five 

 incurved setae below vibrissae, setae on the lower part of the buccae 

 long and fine, though sparse. Face concave in profile, oral margin 

 distinct; antennae black, third segment nearly twice as long as the 

 second, not reaching the oral margin by a distance of over half the 

 length of this segment; arista noticeably thickened at the base, short 

 pubescent to the tip. Frontal stripe dull black, at the narrowest point 

 but little broader than the diameter of the anterior ocellus; orbits gray 

 pruinose, each at the narrowest point over half as wide as the frontal 

 stripe in the same section ; proboscis and palpi fuscous. 



Thorax black, brownish gray pruinose, with three black vittae, the 

 laterals on line with the dorso-central setae. Inner d. c. (acrostichals) 

 small, in two rows; d. c. 2+3: st. 1+2, long; "pra" fine, about a 

 third as long as the following seta. Scutellum with a pair of strong 

 basals, strong subapicals, small apicals, slender discals, besides some 

 finer discal hairs; pubescence of the lower surface restricted to a few 

 fine pale hairs. 



Abdomen gray pruinose, each segment more fuscous at the base and 

 with a median fuscous line narrowing at the posterior margin. The 

 abdomen is more or less cylindrical, wedge-shaped posteriorly, each 

 segment with long slender setulae both dorsally and ventrally, dorsal 

 marginal setae distinctly stronger than the discal setulae; fifth sternite 

 with a wide and deep triangular notch similar to that figured by 

 Schnabl and Dziedzicki for H. janowskii (PI. 26, fig. 691). The hypo- 

 pygium closely resembles that of H. unilineata as figured by these 

 authors on plate 5, figs. 79, 80. 



Legs black, gray pruinose; femora with long fine setae, strongest 

 on the lateral surfaces of the hind pair; fore tibiae each with two 

 outer lateral extensor setae; middle tibiae each with five, one of which 

 is on the basal third on the posterior extensor side, the others, nearly 

 on a level beyond the middle, one anterior, one posterior, one outer, 

 and one inner seta; hind tibiae each with two or more outer lateral 

 flexor, four large outer extensor, three large posterior extensor, and 

 five or more fine inner flexor, setae. Tarsal claws long, setulose at the 

 base, about as long as the pulvilli. 



Wings brownish gray hyaline, veins brown; costal spines small but 

 distinct; veins R 4+5 and M 1+2 parallel or very slightly converging 

 at the tip; extreme tip of R 4+5 slightly reflexed ; Ri ends opposite 

 the r-m crossvein; m-cu crossvein slightly sinuous, perpendicular to 

 Cui; penultimate section of M 1+2 is about two-thirds as long as 

 the ultimate section. Squamae yellow-tinged, upper one covers the 

 lower; halteres dark yellowish. 



9 . — Like the male, except that the antennae are a little shorter ; 

 the lower posterior sterno-pleural seta is much shorter than the upper; 

 "pra" about half as long as the following seta. Setulae of the abdomen
