As Gerstaecker does not mention any gold hair on the anterior 
margin of the thorax in azurea, it is presumably absent, but with 
this exception the present species might, allowing for a moderate 
amount of variation, be identical with azurea. 
The genus Acanthina, Wied., although the natne is preoccupied, 
has been recognized for too many years to be supplanted, as some 
authors desire, by Artemita, Walk. 
Evasa ? flavipes, Big. 
A @ in my collection, taken bv me at Darjiling, 22—30-vi-12, 
is almost certainly this species, the only discrepancy from the 
description being that Bigot’s species has the anterior part of the 
wings broadly darkened, whereas in the present specimen they are 
only a little darkened on the distal part of the wing beyond the 
very black distinct stigma, the proximal half and the costal cell 
being quite clear. ‘The only other described species with all yel- 
low legs is bipars, Walk., which has the dise of the abdomen, 
hind border of the scutellum and a line on each side of the thorax 
yellow. In the present specimen a narrow rather pale ridge runs 
from the wing base nearly to the shoulders. 
Negritomyia maculipennis, Macq. 
(Redescription. ) 
9... Ceylon. Long. II mm. 
Head.—Black, with a little short whitish pubescence. Eyes 
black, shortly pubescent. Antennae blackish, inner side of 3rd 
joint pale, style closely pubescent. Frons at vertex about one- 
fifth the width of the head, widening at level of antennae to nearly 
one-third. An indistinct whitish mark above each antenna. Palpi 
black, with short yellow pubescence. Back of head black; pos- 
terior orbit of eyes with narrow silvery white pubescence. 
Thorax.-Black, moderately shining, with very short black 
hairs; covered with microscopic grey hairs except along a broad 
median line, and on two large spaces towards each side of the dor- 
sum, 1.e., one behind the shoulder and one above each wing. Sides 
of thorax shining black, with microscopic grey pubescence below 
shoulders and some short snow-white hairs above the fore coxae. 
There is also a rather wide, perpendicular side stripe of similar 
pubescence above the middle coxae, joining the dorsal pubes- 
cence in front of the wing. Side spines short, strong, black. 
Scutellum black, with short black hairs and concolorous grey 
pubescence and two broadly separated strong, short, black spines 
on hind margin. 
Abdomen.—Black, with grey pubescence forming a broad 
dorsal line on hinder half and a sub-triangular spot towards each 
side of each segment. Belly shining black, practically bare. 
Legs.—Black, with very minute whitish pubescence. Basal 
fifth of anterior femora and basal fourth of hind pair, also major 
portion (from the base) of all the tarsi pale yellowish white.
