proximad, darker middorsally and in inter- 
segmental areas, distad very lightly pig- 
mented; integumentary sculpturing moder- 
ately distinct on more heavily pigmented por- 
tions, indistinct elsewhere; tergites II-IV 
without submedian spots (female character). 
Small hairs weakly or moderately pigmented, 
larger hairs darker. Chaetotaxy as figured by 
Knight and Chamberlain (1948, Fig. 6). 
larva (K-759). —Head: 0.96 mm. Siphon: 
1.24 mm. Anal saddle: 0.33 mm. Chaetotaxy 
as in Figure 4. 
Head: Width about 0.96 of length; uniformly 
pigmented a light reddish brown; no sculp- 
turing visible; mental plate small, with about 
15 teeth. Hairs of head capsule moderately 
pigmented. Antenna about 0.3 of head, width 
at middle about 0.17 of length; mesal surface 
slightly and uniformly convex, lateral surface 
concave at base, convex beyond middle, pro- 
ducing swelling at about 0.6 from base; uni- 
formly pigmented as head capsule; smooth, 
no sculpturing visible. Antennal hairs moder- 
ately pigmented, except apex of 5 -A. 
Thorax: Stellate hairs with branches of uneven 
lengths and usually ending in a blunt or 
minutely two-spined apex, shaft of branches 
weakly and sparsely feathered; larger simple 
hairs with short elongate spicules; metatho- 
racic spine (7-T) densely covered with minute 
spicules; all hairs well pigmented, brown, 
darker than head capsule. 
Abdomen: Hairs as on thorax. Comb scales 
well pigmented, sharply pointed apically and 
without distinct fringe at 400 X . Siphon index 
about 6.0 (length to median width); moder- 
ately pigmented and with a dark ring at base; 
sculpturing apparently not developed; pecten 
teeth well pigmented. Anal saddle well pig- 
mented, darker at base middorsally; sculp- 
turing not distinct; median width about 0.8 
of length; apicolateral spines well pigmented, 
sharply pointed.
