brown narrow-curved scales and ornamented as follows—a central line of 
golden scales which runs on to a well marked bare space in front of the 
middle lobe of the scutellum but does not run to the end of it and this line 
never forks; on either side on the posterior half of mesonotum is another 
well marked line of golden scales and there is a short line over the roots of 
the wings and scattered golden scales along the anterior margin and on the 
shoulders. In some specimens there is a hint of the anterior lateral 
golden line seen in H. Trilineata but it consists as a rule of a scattered 
golden scale here and there and never a continuous line. Scutellum 
brown. Central lobe with a line of golden narrow-curved scales in the 
centre and small black spatulate scales on either side of this, lateral lobes 
with black narrow-curved scales. Bristles of central lobe pale golden 
in the centre and dark brown on either side. Pleurae dark brown 
with patches of silvery racquet-shaped scales. Wings with dark brown 
scales the lateral scales broadly linear though towards the apex of 
the wing they are slightly clavate; fork cells long, first longer than 
second, its base nearer wing base, its stem not half the length of the cell; 
posterior cross-vein but little more than its own length from the median! 
Coxae creamy-white ; femora clad with black scales a small patch of creamy 
scales on the upper surface of apex of fore femora and an oval silvery patch 
on the posterior surface of hind femora near its middle; metatarsi and first 
tarsal joints of fore and mid legs with narrow creamy basal bands, a broad 
creamy band at the base of metatarsus of hind legs and a broad white band 
at the base of the first and the. second tarsal joints; fore and mid ungues 
equal and uni-serrate. 
Abdomen. Clad with black scales with pearly lateral spots and creamy 
basal white bands on the venter. 
Male. —Antennae plumose with coal-black plumes. Proboscis long and 
with a ridge about its middle suggesting a joint. Palpi not more than three- i 
quarters the length of the proboscis, slender clad with black scales with a white 
patch on the under surface of the base of the ultimate joint and golden 
spines at its apex. Rows of golden spines on all the femora. Fore and 
mid ungues very large unequal and each unguis bears a tooth. Lateral j 
abdominal spots extend more on to the dorsum than in the female and 
nearly form complete bands. 
Occurrence .—Described from a series bred from larvae taken from water 
collected in fallen leaves in the jungle at Jugra. 
Remarks .—Though closely resembling H. Trilineata a careful com- 
parision shows sufficient differences to warrant the separation of the two. 
The central golden line on the mesonotum in H. Trilineata invariably i 
forks and the two arms of the fork enclose the bare space in front of 
scutellum ; in this mosquito it never forks but runs over part of the bare ! 
space. The two anterior lateral lines conspicuous in H. Trilineata 
are either entirely absent in this species or represented by merely a scattered 
scale or two. The specimens are very perfect so that this is not due to 
denudation. The proboscis in Trilineata is always more or less banded 
and the palpi with well marked snowy tips, in Jugraensis the proboscis is 
never banded and the palpi shew but one or two pale scales at the tips. The
