Aedes of the Philippines — Knight and Hull 
double; 20 with 1-3. Mentum with 7-10 
lateral teeth. Thorax: Some of the meso- and 
metathoracic hairs stellate-type. Prothoracic 
hair 0 with about 7—10 branches, small, stel- 
late; hair 1 with 2-4 branches; 2 single; 3 
with 5-7. Mesothoracic hair 9 with 6-7 
branches, very long, stout; 10 and 12 single, 
long, stout; 11 with 1-3 minute branches. 
Metathoracic hair 9 with 5-7 branches; 10 
and 11 as on mesothorax; 12 single, greatly 
reduced in size. Abdomen: Some of the dorsal 
and ventral hairs stellate-type. Dorso-lateral 
hairs of I and II with 3-4 branches. Lateral 
hairs of I-VI double, rarely triple. Pentad 
hair 1 with 3— 6 branches; 3 with 9~10; 5 with 
4-6. Comb with about 28 to 35 scales in a 
patch, scales apically broadened and com-

pletely fringed. Siphon brownish, detached 
acus present, index 2. 4-3. 3; 18-29 pecten 
teeth, each with a strong ventral denticle 
near middle and a fine fringe from denticle to 
base; siphon hair tuft inserted beyond middle 
and shortly before the end of the line of 
pecten teeth, with 5-9 plumose branches; 
dorso-lateral valve hair approximately as long 
as siphon diameter at apex; the two ventro- 
lateral valve hairs shorter than the valve in 
length. Anal plate narrowly incomplete, 
posterior margin heavily spined both above 
and below lh\ Ih with 1-2 branches; he with 
4-6; ventral brush of 10 tufts, all but the 
basal 1-3 tufts arising from a heavily sclero- 
tized, connected barred area, each tuft with 
4-8 branches. Anal gills tapered from base, 
dorsal pair slightly longer than ventral pair 
and 1.25-1.5 times longer than the anal plate. 
Four larvae from Tacloban, Leyte, differed 
from the above series in having the anal gills 
almost bud-like and the abdominal hairs 
much less developed. The specimen from 
Palawan and two of those from Tacloban 
had a curious medial lateral bulge on the pre- 
clypeal spine. 
BIONOMICS: The adults were not encoun- 
tered in nature. All the larval material of this 
species was taken from various types of tree 
holes, except for the collection from Busu- 
anga, which was found in a water-holding 
enameled refrigerator. 
DISTRIBUTION: Specimens examined. R. K. L. 
(10 males, 19 females, 23 sets assoc, skins, 1 
larva). Luzon: Olongapo, Subic Bay, Zam- 
bales Prov. (Rozeboom). Palawan: Balsahan 
River (Johnson, Laffoon). Culion: Pilapil 
(Laffoon, Fitzgerald). Busuanga: Coron (Fitz- 
gerald). A.N.S.P. Leyte: Tacloban (Roberts). 
C.A.S. Mindoro: San Jose (Ross). 
Literature records. Palawan: Puerto Princesa 
(Bohart, 1945: 57). 
Unknown outside the Philippines. 
DISCUSSION: This species, which is the sole 
representative of Group B in the Philippines, 
is closely related to plumiferus King and 
Hoogstraal from New Guinea.
