220 A Monograph of Culicidae. 
Observations.—Described from a single 9 sent me by Dr. 
Sergent in perfect condition, but full of blood, the abdomen 
being much distended, and, as usual under such circumstances, 
jet black. It is closely related to Culex geniculatus, Olivier, but 
differs in having no white scales on the palpi, in having a much 
longer stem to the second posterior cell, the posterior cross-vein 
being much further distant from the mid than in C. geniculatus, 
and in having the large expanded apical lateral white abdominal 
spots. From the swollen dark state of the insect it is evidently 
a blood-sucker.

The following is Dr. Neveu-Lemaire’s description :— 
Head brown; antennae longer than the proboscisin the 2; maxillary 
palpi very small, much shorter than the third of the proboscis, and formed 
of three joints in the 9. Thorax brown, with a longitudinal yellow line ; 
the wings not extending farther than the abdomen, transparent, with a 
brown costal stripe less defined about the middle. Legs unbanded, 
covered with scales and hairs; ungues of 9? all equal and uniserrated. 
Abdomen brown, the dorsal surface with yellow apical bands; ventral 
surface yellow, with black apical bands, lateral spots pale. 
?. Head brown; the occiput has a tuft of small yellow scales, 
straight and bifurcated at their extremity, a pale line around the eyes. 
The antennae are longer than the proboscis, and measure 2°48 mm.; they 
are fawn coloured, with paler spaces at the articulations. The maxillary 
palps are less than a third of the proboscis, they measure 0°37 mm. ; 
they are formed of three joints, the third is longer than the two others 
and truncated at the end; they are fawn coloured, and clothed densely 
with scales and some hairs. ‘The proboscis measures 2°21 mm.; it is 
brownish, and covered with flat scales. The thorax is brown, with a pale 
median longitudinal band on the dorsal surface, formed of little pale 
yellow narrow-curved scales. On the anterior portion are found two 
parallel dark lines, close together. On the posterior part are two similar 
lines, but longer and further apart than the others; the scutellum and 
the sides of the thorax are similarly coloured brown. The wings are not 
longer than the abdomen and not spotted, but have a dark costal line, 
due to accumulation of scales on the costal area. The first sub-marginal 
cell is longer and narrower than the second posterior, and both are very 
short; the supernumerary transverse is connected with the middle 
transverse and forms a very obtuse angle; the posterior transverse is 
much nearer the base of the wing than the middle transverse. The 
scales are of typical Culex form. ‘The halteres are yellowish-brown. 
Legs unbanded ; coxae yellow; the femora fawn, those of the third
