taken together shorter than the one preceding, in the male long 
haired; antennae 15 jointed, the basai joint disklike, the follow- 
ing ones small, in the male long haired, in the female short and ~ 
sparsely haired; eyes somewhat reniform, the ocelli wanting; 
the inesothorax rather long and somewhat pointed in front, and 
without transverse suture; scutellum narrow, the metathorax 
rather prominent; abdomen long and slender, eight jointed, the 
genitalia small and inconspicuous; legs long and slender, nearly 
bare; wings with the veins and the margin thickly haired, the 
venation as in the figure. 
The females may be easily distinguished from Culex by the 
presence of palpi about as long as the proboscis; the male may 
be distinguished by the following characters. In Anopheles the 
last two palpal joints are much thicker than the first and second, 
and spatulate in form, while in Culex they are the same in diam- 
eter, the last one more or less pointed; further, in all the species 
which I have examined, a stump of a vein extends back into the 
basal cell from the base of the radial sector and another from 
base of R,+,; this venation seems to be rare in Culex; in our 
species also the fourth tarsal joint of the fore leg in Anopheles 
is more than twice as long as wide, while in Culex it is no longer 
than wide.

Male. Brown, covered with cinereous hair; head, antennae 
including the long hairs, palpi and proboscis uniform brown; 
thorax dark brown with three longitudinal cinereous stripes, 
the middle one divided by a fine brown line covered with sparse 
yellow hairs; pleura and scutellum, cinereous brown; metano- 
tum and abdomen dark brown, the latter with the basal two 
thirds and the extreme posterior edge of each segment with a cin- 
ereous bloom, and covered with brown erect hairs; genitalia of 
moderate size, consisting of two, two jointed appendages, the 
joints of about equal length, the second one slender, curved and — 
pointed. On the ventral aspect is a sharp caudad projecting 
spur [fig.10]. Legs uniformly brown except the knees and the 
extreme tips of the tibiae, which are yellow. The fore tarsal 
claws have each a long toothed claw and a very short simple 
one. The feet of the middle and hind legs each have two simple
