PUPA (Exuviae of holotype, 624-24).— Ab- 
domen: 1.65 mm. Trumpet: 0.60 mm. Pad- 
dle: 0.40 mm. 
Cephalothorax: Dark pigmentation of apical 
portions of wing cases and mid-ventral line, 
including all of leg cases, contrasting very 
sharply with the light pigmentation of the 
remainder. Trumpet dark on tracheoid and 
apex of pinna, light in between and at base; 
length 13.0 median width; parallel-sided to 
about 0.6, then gradually slightly flared; in- 
ner wall indistinct except at apex; tracheoid 
extending to 0.55, absent from basal 0.1; reti- 
culations absent, replaced by minute, sparse 
spicules; pinna about 0.05, opening almost 
circular; a distinct slit in meatus extending 
about one-half distance of reticulate. All hairs 
lightly pigmented and simple; relative posi- 
tion, length, and degree of development as 
figured; larger branched hairs, except 8-C, 
with base elongate proximally and moderate- 
ly expanded distally where branches arise.

5(13, I4b), 6(1), 7(5, 7b, branches as distinct 
as in other hairs), 8(5, 6b, central stem long 
and heavy, basal branches short and slender), 
9(6, 8b, branches as distinct as in other hairs, 
outer shorter), 10 (6b, outer branches shorter), 
11 (5b), 12(8, lib, outer branches shorter). 
Abdomen: Lightly pigmented on I and II, pro- 
gressively darker distad, except for caudolat- 
eral lighter areas on V-VII; tergites III-VII 
with a small posteromedian patch of short, 
heavy spicules; tergite II with a larger, more 
anterior patch; tergite VIII with large an- 
teromedian patch of arcuately transverse lines 
of spicules; reticulations not visible; sternites 
II-VIII with extensive median patch of small- 
er spicules, arranged in transverse arcuate lines 
on more proximal segments. Hairs lightly 
pigmented on basal segments, darker caudal- 
ly; relative position, length, and degree of 
development as figured; larger branched hairs 
with elongate basal stems which are not ex-
