New Species of Aedes — Knight and Hull 
199 
sasi were directly compared with the type. 
It seems likely that when more material is 
available, kabaenensis and haisasi will prove to 
be members (subspecies) of a single poly- 
typic species. 
As pointed out above, haisasi and kabae- 
nensis differ markedly from the other known 
Geoskusea species in having the male palpi 
approximately two-thirds as long as the pro- 
boscis. Also, conspicuous differences occur 
in the male genitalia. 
This species is dedicated to Mr. F. E. 
Baisas, Malaria Control Section, Department 
of Health, Manila, Republic of the Philip- 
pines, who has contributed so materially to 
our knowledge of Philippine mosquitoes.

1929- A. {Aed.) lowisi Theo. Edwards, Not. 
Ent. 9:5. 
1934. Aedes {Aedimorphus) sp. Edwards, foot- 
note, in Barraud, Fauna Brit. Ind., Dipt. 
5:250. Called attention to the fact that 
material named as lowisi by Edwards 
(1929:5) in actuality represents another 
species. 
Adult: 
MALE. Head: Proboscis coloration obliter- 
ated. Palpi longer than the proboscis by 
slightly more than the length of the apical 
segment; dark; segments IV-V down- tilted, 
numerous long hairs arising apically and all 
along IV and V. Vertex with a narrow area of 
narrow pale scales along the dorsal portion of 
the eye margins; remainder of vertex with 
broad yellowish-white scales; brown upright- 
forked scales over the whole dorsum. Thorax: 
Scutal integument brown; badly rubbed, with 
some small narrow brown scales, marked on 
either side with at least two small clusters of 
yellow scales, one on the anterior margin and 
the other on a line with the first and on a level 
with the scutal angle. Scutellar lobes covered 
with broad silvery- white scales. Apn with a 
few broad silvery scales ; ppn bare. Propleuron, 
upper sternopleuron, lower posterior sterno- 
pleuron, and upper mesepimeron each with a 
small patch of broad silvery- white scales; a 
few narrow yellowish scales on the subspira- 
cular area. Legs: Femora and tibiae each with an 
apical patch of silvery-white scales anteriorly. 
Fore and mid tarsi dark, hind tarsal segments 
II-V missing but a narrow area of apical pale 
scales on I. Wings: Dark-scaled. A spot of 
silvery-white scales at the base of the costal 
vein. Halter knob with dusky scales. Abdo- 
men: Tergite I with a lateral band of silvery- 
white scales ; III-VI with basal bands of white 
scales, VII-VIII removed with genitalia and 
scale coloration lost. Sternites with brownish- 
yellow scales basally, brown scales apically. 
Genitalia: Basistyle without lobes; tergal sur- 
face with numerous very small setae, these 
extending laterad to the large lateral setae; 
sternal surface with a regular longitudinal 
row of stout long hairs near to mesal margin. 
Dististyle distinctively shaped as figured. 
Ninth tergite slightly concave medially. 
FEMALE. Differs from the male mainly as 
follows: Proboscis pale beneath from near 
base to shortly beyond middle. Vertex with 
Fig. 2. A. {Aedimorphus) mindoroensis. Tergal aspect 
of male genitalia.
