Fig. 1 . Tripteroides (M.) caledomca (Edwards, 1922). 
Fourth instar larva; terminal abdominal segments, left 
lateral aspect. La Coulee River, New Caledonia, Ne-

Description 
adults. — Very similar to melanesiensis. I 
have seen six females, four pinned, one pre- 
served in alcohol and the other fully developed 
in situ in the pupal skin, and eight males, 
three pinned and five in situ in pupal skins. 
Both sexes may be separated from T. mela- 
nesiensis by the presence of several broad, 
semi-appressed, apically rounded or truncate, 
dark scales among the posterior supraalar 
bristles. The following additional information 
about the types, obtained by Dr. Mattingly 
at my request, may be of interest: whitish 
scales in front of wing root are not broad and 
flat but a trifle broader than elsewhere (as in 
melanesiensis ) ; dorsocentrals seven on each 
side in line plus three or four at posterior 
end and two or more prescutellars (meso- 
notum disfigured in this region in both spec- 
imens) ; posterior pronotum with white scales 
in upper part (as in melanesiensis ); lower ster- 
nopleuron with scales and bristles as in 
melanesiensis; propleurals four. Male.— Leg 1: 
femur 1; tibia 0.96; tarsus 0.61, 0.31, 0.21, 
0.04, 0.08; leg 2: femur 0.90; tibia 0.99; tarsus 
0.75, 0.39, 0.24, 0.06, 0.06; leg 3: femur 0.86; 
tibia 0.84; tarsus 1.08, 0.63, 0.46, 0.29, 0.11. 
Female.— Leg 1: femur 1; tibia 0.99; tarsus 
0.66, 0.36, 0.23, 0.11, 0.08; leg 2: femur 0.93; 
tibia 1.03; tarsus 0.78, 0.43, .0.25, 0.11, 0.07; 
leg 3: femur 0.90; tibia 0.92; tarsus 1.08, 0.64, 
0.47, 0.29, 0.10. 
pupa. — Abdomen: 3.60 mm. Trumpet: 0.45 
mm. Paddle: 0.50 mm. Cephalothorax: Very 
lightly pigmented except middorsally and on 
metanotum. Trumpet very dark brown, lighter 
apically; length about 2.3 median width; 
basal 0.11 parallel sided, width about 0.25 
of median width; distally suddenly expanded; 
smooth convex on posterior margin, with a 
medium bulge on anterior margin; inner wall 
distinctly separated to apex on anterior mar- 
gin; tracheoid on mesal surface of basal stalk 
only; reticulate distinct, without conspicuous 
spicules; pinna about 0.39. Hairs heavily to 
moderately pigmented. Hairs: l(2b from 
base, very long), 2 (2b from near base), 3(1, 
equal to 2, about one-fourth length of 1), 
4(2b, long), 5(1, long), 6(1, short), 7 (4b, 
moderate), 8(1, about half as long as 1), 
9(1, 2b, about one-third as long as 1), 10(2b, 
short), 11(1, medium), 12(1, long). 
Abdomen: Very lightly pigmented except mid- 
dorsally proximad, intersegmental areas very 
dark at base; integumentary sculpturing dis- 
tinct on darker segmental areas; tergites 2-4 
each with a pair of elongate transverse sub- 
median dark spots (male character). All hairs 
moderately to well pigmented. Segment 1: 
hair 1 (about 30 primary branches, arising from 
elongate stem and enlarged base, with sec-
