asal bands on the hind leg are much broader in Trilineata than in 
u^raensis. Finally the larvae are very markedly different. _ The name 
'rilineata is an unfortunate one as there are really seven distinct lines on 
l Trilineata whereas in H. Jugraensis there are only three, but the names 
mst stand as H. Trilineata was named before the discovery of H. 
ugraensis. 
Hulecoeteomyia Fluviatilis. n. sp. 
A large triangular patch of golden narrow-curved scales on the upper 
,urfa*ce of the head the apex of the triangle reaching to the vertex, a narrow 
nargin of similar scales along the upper half of the orbit the rest of t e 
ipper surface clad with dark brown almost black spatulate scales, 
vhile laterally there is a patch of creamy-white spatulate scales ; dark umber- 
)rown upright forked scales are inserted as far forward as the orbital 
nargins. Mesonotum with seven lines of golden scales and dark bronze- 
Drown scales between. Metatarsi and first two tarsal joints of all legs 
□anded with creamy scales. Proboscis and palpi scaled dark brown with a 
few white scales on the tips of the palps in some specimens. 
Female, Head. —Purple-black ; upper part clad with narrow curved scales 
of different colours arranged as follows a narrow line along the upper halt 
of the orbital margin of each side deep gold in colour, a broad central 
line running backwards to the occipital foramen composed of scales which 
in some lights are almost white in others pale golden but m a fresh speci¬ 
men are distinctly golden numerous golden scales loosely scattered over the 
nape and dark brown spatulate scales forming an eye-like spot on each side 
behind the golden scales of the orbital margin, and beyond these there is a 
large patch of creamy small spatulate scales. Numerous dark brown up¬ 
right forked scales are inserted on the occiput and as far forwards as the 
orbital margins. A tuft of pale golden vertical bristles project t> etvve e n the 
eves; orbital bristles dark brown. Basal joint of antenna light brown 
darker brown on the inner face which is clad with small dark brown scales, 
base of second joint light brown upper half dark brown with blackish-brown 
scales, remaining joints dark brown with silvery short hairs and dark 
brown verticillate hairs. Clypeus purple-brown. Palps dark brown with 
dark blackish-brown scales and some white scales at the tips, m length 
rather less than one-third the length of the proboscis. Proboscis scaled as 
the palpi. 
Thorax .—Prothoracic lobes dark purple with a band of creamy flat 
scales running obliquely from the upper part in front downwards and back¬ 
wards ; part of the lobe is bare. Mesonotum chestnut-brown clad with 
dark brown narrow-curved scales and ornamented with seven lines of golden 
narrow-curved scales, a central line down the.whole length forking m front 
of the scutellum, a lateral line on either side in front ending a little in front 
of a line joining the wing bases, and a similar line on each side placed just 
external to this which runs backwards to base of lateral lobe of scutellum 
and a line over the roots of the wings, while round the margin in front is a 
band of golden scales. Mesonotal bristles dark brown. Scutellum light 
brown ; Sn the middle lobe is a central line of golden narrow-curved scales 
flanked on either side by dark blackish-brown spatulate scales, the lateral
