Abdomen .—Clad with dark purple-brown scales. Some of the segments 
have dorsal apical white bands the number and size of these bands varies 
but there is always a white band on the fifth segment which extend!! 
laterally to the venter. 
Male. Markedly plumose antennae. Mid ungues unequal the larger 
unguis simple but much curved. In other respects the male resembles the 
female. 
Occurrence .—This mosquito is caught near its breeding places which 
are any swampy bits of open ground. 
Remarks. In many points this mosquito so closely resembles V. 
Pygmcea , Theobald, that I have some doubts about describing it as a 
new species. At the time of Mr. Theobald’s description of Pygmcea there 
were very few Malayan Uranotaenia known and hence points which are 
common to many species are emphasized as distinctive marks of Pygmcea 
and minor points were not brought out. The bluish-white line in front of 
the wings helps one but little as the majority of Malayan Uranotaeniae have 
this. 1 he only points of difference between Campcstris and Pygmcea seem to 
be the absence in Campestris of white scales on the stem of the fifth vein of the 
tlie colour of the head scaling which in Campestris is distinctly bluish- 
white and dark olive-brown changing to dark blue in some lights and not 
black as in Pygmcea. There are other minor differences of colour which 
lead me to the conclusion that Campestris is a distinct species for in any 
other members of the genus which are undoubtedly distinct species the 
differences are often very small in the adults while well marked in the 
larval stage. 
Uranot^nia Argyrotarsis. n. sp. 
Thorax dark umber-brown with bronzy narrow scales, a bluish-white 
line of erect lanceolate scales in front of the wing, another crossing the 
pleura, blue scales on the prothoracic lobes. Head with pale blue scales 
on the vertex and along the orbital margins, rich dark blue scales behind. 
Antennae long, proboscis much longer than the abdomen. Legs brown, 
last three tarsi of the hind legs creamy, dorsum of abdominal segments two 
to four almost entirely scaled with bluish-white scales, remaining segments 
with blackish-brown scales. 
. Female Head .—On the vertex there is a patch of long lanceolate bluish- 
white scales, along the orbital margin on each side a line of bluish-white 
flat scales which is very broad leaving but a small area cn the nape covered 
by dark blue scales and a few rows of almost black upright forked scales; 
two long dark brown vertical bristles and some dark brown orbital! 
Antennae rather long, basal joint dusky, naked, second joint longer than 
succeeding joint, pale at the base, blackish-brown at the apex, remaining 
joints blackish-brown with silky-white hairs and dark brown verticils. 
Clypeus dark brown. Palpi very minute closely applied to the clypeus clad 
with dark brown scales. Proboscis long much longer than the abdomen 
enlarged apically clad with dark brown scales. 
Thorax .—Prothoracic lobes brown, clad with rather large pale bluish- 
white racquet-shaped scales which run obliquely across forming a line with 
the line on the pleura. Mesonotum dark brown with two ill-defined paler 
lines on either side of the middle line clad with narrow-curved scales which
