New Species of Aedes — Knight and Hull 
Aedes (?) platyleptdus n. sp. 
Adult: 
MALE. Unknown, 
FEMALE. Wing length 2. 5-3.0 mm. Head: 
Proboscis dark, approximately equal to fore 
femur in length, apical portion may be some- 
what laterally compressed. Palpus one-hfth 
as long as proboscis, dark. Torus with broad 
silvery scales medially. Vertex broad-scaled, 
dorsum black, an anteromedian patch of 
silvery scales that extends laterally as a line 
along the eye margins, extreme margin of 
lateral aspect with an area of palish translucent 
scales, a clump of short black upright-forked 
scales on the nape. Thorax: Scutal integument 
dark brown, covered with overlapping broad 
plate-like scales, these scales blackish-brown 
and possessing a metallic luster, only a very 
small central portion of the prescutellar space 
free of scales; a few bristles on the anterior 
margin and a clump over the wing base, but 
no prescutellar, dorsocentral, or acrostichal 
bristles. Scutellum completely covered with 
the same type of broad dark scale that is 
found on the scutum, the line between the 
scutum and scutellum completely hidden by 
the overlapping of the scutal scaling. Post- 
notum bare. Apn (not particularly approx- 
imated dorsally) covered with overlapping 
broad black scales; ppn bare of scales, about 
3 posterior bristles. Pleural integument dark; 
paratergite very broad; postspiracular area 
with only 2-3 small hairs, 1 propleural bristle, 
only about 1 sternopleural bristle (located 
posteromedially) , only a few dorsal mesepi- 
meral hairs (nearly covered by scale patch; 
was not possible to be completely sure that 
no lower mesepimeral bristle occurs). Follow- 
ing areas each with a patch of broad over- 
lapping silvery scales: propleuron, the an- 
terior area between the fore coxae (proster- 
num), all of the sternopleuron except a small 
anteroventral area, and all of the mesepimeron 
except along the posterior margin. Base of 
meron slightly above base of hind coxa. 
Legs: Coxae anteriorly covered with over- 
lapping broad silvery scales, some dark scales 
on mid coxa. Fore and mid femora anteriorly 
dark except for a small pale basal area and 
narrow white apical spots (may be absent on 
fore femur), posteriorly dark except for a 
basal pale area; hind femur white, apical one- 
third black except for a narrow white apical 
ring. Tibiae black. Fore and mid tarsi black 
except for a small dorsobasal white spot on 
I ; hind tarsal segment I with a white band on 
slightly less than basal one-fourth (incom- 
plete mesally), II all dark (a few basal white 
scales present), III dorsally all white except 
for a narrow apical area, (extending onto 
lateral surfaces), IV-V all dark. Tarsal claws 
equal, simple. Wings: Dark-scaled. Dorsally 
the convex veins with small broad scales, the 
concave veins with narrow scales. Squama 
fringed. Bases of anterior and posterior fork 
cells approximately even. Vein 6 reaching 
distinctly beyond base of fork of vein 5. 
Halter pale, knob dark-scaled. On a wing of 
one specimen a hair was observed near base 
of vein 1. Abdomen: Tergites black-scaled, 
lateral margin of I with a silvery-scaled band, 
II-VI with basolateral silvery-white spots and 
narrow dorsobasal silvery bands (connected 
to the spots) on III-VI. Sternites with white 
basal bands. Eighth segment completely 
withdrawn into the seventh. 
Larva: 
Unknown. 
Types: 
Holotype. Female (810.8), Puerto Princesa, 
Palawan Island, Philippines, May 24, 1945 
(J. L. Laffoon and D. R. Johnson), reared 
from a tree hole larval collection. Paratypes. 
One female (1608.2), Cape Melville, Balabac 
Island, Philippines, June 23, 1945 (D. R. 
Johnson), reared from a larva collected in a 
fallen coconut spathe. One female (1620.1), 
Cape Melville, Balabac, June 23, 1945 (J. L. 
Laffoon), reared from a larval collection from 
a log depression in a mangrove area. 
The holotype and one paratype are de- 
posited in the U. S. National Museum. The
