Fig. 19. A. (Stegomyia) hamhusicolus. Larva (Mindoro). 
a, Head; b, terminal segments. 
DISTRIBUTION: Specimens examined. U.S: 
N.M. Mindanao: San Ramon, Zamboanga 
Prov.; Maasin Village, City of Zamboanga 
Prov.; 2 sets assoc, skins, Sitio Taglawig, 
Tagum, Davao Prov. (Hoogstraal) ; 1 set 
assoc, skins, Lanao, nr. Lanao-Cotabato 
boundary along Parang-Malabang hwy. (En- 
ke, Hoogstraal); 1 set assoc, skins, Matanao, 
Santa Cruz, Davao Prov. (Enke, Corcega). 
Unknown outside the Philippines. 
DISCUSSION: An examination of the type 
male and allotype female of pseudalbolineatus 
Brug in the British Museum showed it to be 
very similar to laffooni. The only differences of 
any importance at all were in the markings of 
the hind tarsi of the female. In pseudalbolinea- 
tus female, the basal band on hind tarsal III 
occupies seven eighths of the segment, and 
only one pale basal scale occurred on IV. It 
seems extremely likely that when more ma- 
terial is available from the Netherlands East 
Indies, from the Philippines, and from the 
intervening regions, these two will be found 
to be either synonyms or at the most only 
subspecies. As pointed out previously, this 
species is closely similar to arboricolus.

DISCUSSION: While examining types in the 
British Museum, the senior author discovered 
that the female type specimen of Culex im- 
patibilis Walker, which Edwards (1932: 162) 
had made a synonym of aegypti, is in actuality 
a member of the albolineatus complex. This 
specimen was identified as the type by E. A. 
Waterhouse and since Walker’s description 
mentions only the male, there is some ques- 
tion as to the validity of this type specimen. 
This specimen, which is from Makassar, 
Celebes (Wallace), has the scutum badly 
rubbed, the legs entirely missing except the 
femur, tibia, and first tarsal segment of one 
hind leg, and all but the first two segments of 
the abdomen missing. However, sufficient 
scaling remains to key the specimen to hoog-
