PACIFIC SCIENCE, VoL VII, July, 1953 
as figured. Mesosome with an incompletely 
sclerotized ventral bridge in addition to dor- 
sal bridge; an apical and a median spine on 
each plate, apical spine projecting laterad, 
median mesad, spines subequal. Paramere 
with a weakly sclerotized median expansion

PUPA (Exuviae of holotype, 504-44).— Ab- 
domen: 1.83 mm. Trumpet: 0.32 mm. Pad- 
dle: 0.50 mm, 
Cephalothorax: Uniformly moderately pig- 
mented, slightly darker on leg cases and 
metanotum. Trumpet uniformly darkly pig- 
mented; length 5.30 of median width; gradu- 
ally widened to apex; inner wall indistinct; 
tracheoid extending about 0.5 on lateral sur- 
face, very poorly developed on mesal surface 
except at extreme base; reticulate with im- 
brications ending each in one sharp spicule, 
more distinct on mesal surface and extending 
basad through the tracheoid portion; pinna 
about 0.23; distinct mesal slit in meatus ex- 
tending about 0.18 of trumpet length. Hairs 
moderately pigmented and simple; relative 
position, length, and degree of development 
as figured; larger branched hairs with slender 
base slightly expanded apically where branch- 
es arise. Hairs: l(5b), 2(5, 6b), 3(5b), 4(4, 
6b), 5(6, 7b), 6(1), 7(4f, base simple), 8(7b), 
9(6b, base simple), 10(4b), ll(2b), 12(5, 6b). 
Abdomen: Moderately pigmented, somewhat 
darker basally, ventral intersegmental sclero- 
tizations darker; tergites III-VII each with a 
posteromedian patch of distinct small spi- 
cules; tergite II with larger patch extending 
cephalad; tergite VIII with smaller median 
patch; tergal integumentary reticulations in- 
distinct; sternites III-VII each with extensive 
median patch of small spicules; sternite II 
with narrow caudal transverse band of spi- 
cules arising from faint arcuate imbrications; 
sternite VIII with smaller anteromedian patch 
of spicules. All hairs moderately pigmented; 
relative position, length, and degree of de- 
velopment as figured; larger branched hairs 
with inconspicuous short basal part only 
slightly enlarged apically where branches 
arise. Segment I: hair 1(14, 16 primary branch- 
es, dense brush-like secondary branching at
