dle: 0.58. 
Cephalothorax: Moderately pigmented; ap-

Trumpet brilliant brown; length 2.8 median 
width; gradually widened from base to about 
0.5, then almost parallel-sided; inner wall dis- 
tinctly separated throughout, distinctly con- 
stricted at 0.5 and then flared out, apical 
portion with conspicuous elongate imbrica- 
tions; tracheoid very poorly developed, re- 
stricted to basal 0.25 of anterior face; reticulate 
with indistinct small shallow imbrications, 
without spicules; pinna 0.2; no slit in meatus. 
Hairs moderately to strongly pigmented; rel- 
ative position, length, and degree of develop- 
ment as figured; branched hairs with simple 
base, barbs absent except as noted. Hairs:

spicuous apical and subapical brush of barbs), 
11(1, minutely barbed), 12(1), extra hair on 
left side caudad of 12, probably homolog of 
larval hair 4-T. 
Abdomen: Strongly pigmented on proximal 
segments with lighter areas around bases of 
hairs; distal segments moderately pigmented; 
tergites II-VIII with imbrications more dis- 
tinct on proximal segments and bearing small 
apical spicules which are larger toward mid- 
line and form extensive patches; tergite I with 
patch of small spicules on median bridge 
cephalad of float hairs; sternites II-VIII with 
entire surface ornamented with small spicules 
arising from faint imbrications. Large hairs 
very darkly pigmented, smaller moderately; 
relative position, length, and degree of de- 
velopment as figured; branched hairs with
