long and very distinct clad with a double row ol small median scales and 
on the upper edge of the apical fourth with clavate lateral scales; branches 
of first fork cell with numerous rather large clavate lateral scales, a few 
lateral scales on the apical half of third vein, and a few on the branches of 
second fork cell; stem of first fork cell with double row of median scales, 
all the remaining veins posterior to it with a single row of median; fork 
cells of about equal breadth and with their bases level, the first longer than 
the second, being a trifle longer than its stem. Median and posterior cros^ 
veins of about equal length, posterior distant from median rather more than 
its own length. Coxae muddy-yellow with white scales on all, and some 
dark ones on the fore coxae and a row of hairs; fore femora almost entirely 
dark brown scaled, with a row of large golden-brown spines and a ring of 
spines round the apex; tibiae with dark brown scales and short spines, 
tarsus with fawny-brown scales, only seen in certain lights, in some 
lights the scales look as dark as those on the tibia. Mid and hind femora 
dark brown above with silvery scales beneath; some pale scales at the apex , 
tibiae with dark brown scales and a ring of pale ones at the apices; short 
spines on the mid tibiae much longer ones on the hind tibiae; metatarsi and 
tarsi with dark brown scales presenting the same difference ot shade with 
change of lights as those on the fore tarsi. All the brown scales in some 
lights show metallic-bronzy reflections. Fore and mid ungues large and 
unequal; the large unguis uni-serrate; hind simple and equal. 
Abdomen .—With dark purple-brown scales above and quadrilateral 
pearly-white basal spots to each segment. The segment bearing the 
genitalia is much enlarged. The tergite is of a pyramidal shape with 
deep notch in the apex. It is purple scaled at the base, of a greyish colour 
on the margins and at the apex the grey surrounds, a small tawny 
unsealed area. The margin bears numerous golden hairs. The basal 
piece of each clasper of unusual size and round in shape clad with nume¬ 
rous long pale golden hairs. At the apex a pair of claspers are inserted 
the larger being of great length and two pronged and being inserted on the 
posterior of ventral margin of the basal piece while the other smallet 
clasper is inserted more anteriorly and consists of a thick dark brown 
chitinous spine with a blunt tooth on one edge. At rest they look back¬ 
wards and inwards. The internal pair of claspers can be made out with 
difficulty owing to the direction the fly has set in. The large external 
claspers first bends upwards (dorsal-wards) and then sharply inwards and 
at rest the prongs of the opposite claspers interlock. I know of no mosquito 
with genitalia in any way comparable to this mosquito.

Lumpur at evening. It is a distinct Aioretomyia with a tew narrow-cur\ ed 
scales on the vertex and nape flat scales elsew T here short palpi and curiously 
complex genitalia.
