certain lights. The rows of minute dorso-central bristly hairs 
diverge until they meet two strong bristles, one placed towards 
each posterior corner of the dorsum. Three bristles on each side 
below the dorsum. Scutellum with the inner pair of bristles much 
longer than the outer pair. 
Abdomen wholly rich dark reddish brown, unmarked, almost 
bare; stiff hairs along the sides, and no apical bristles. The 3rd 
and 4th joints of the hind tarsi are light brown, instead of 
wholly yellow as in argyrogyna, and the 2nd joint is more cut 
away at the base on the underside than in Meijere’s species. 
Stigmatic cell very pale yellow, but that is also the case to 
some extent in argyrogyna. 
Described froma single @ in the Indian Museum from Sadiya. 
Platypeza obscura, mihi, sp. nov. 
@. Darjiling District. Long. 2+—3 mm. 
Also considerably resembling argyrogyna. ‘The eyes have the 
upper facets large and bright cherry red, the lower ones very much 
smaller, chocolate brown. Posterior margins of eyes with a dis- 
tinct fringe of black hairs. Antennae bright yellow, arista dis- 
tinctly thickened for some distance from base, bright yellow, the 
bristle black, mouth and palpi bright yellow. 
Thorax.—Dorsum blackish grey in both sexes; without sign of 
any white shimmer. In addition to two or three bristles of differ- 
ent lengths close together, towards each side near hinder margin 
of dorsum there are three similar ones on the sides of the thorax, 
below the posterior calli. There are two on each humeral callus, 
and three stronger ones a little below them. Scutellar spines 
equal in size. 
Abdomen blackish grey, without bands, and with seven or 
eight bristles at the tip. Legs rather paler than in argyrogyna; 
hind tarsi dull yellow, without the bright golden yellow pubescence 
of that species, posterior margins of segments with the black 
bristles more distinct, and continued further over the lateral edges. 
The first four hind tarsal segments more nearly equal in length 
than in the other species. 
Described froma @ from Kurseong, 4—6-vii-08 [Annandale]. 
Notes on Platypeza. 
Walker’s glaucescens, # 2 was the first oriental species 
described (Proc. Linn. Soc. Lond., iv, 117), and this although very 
briefly diagnosed should be a good one. According to that author 
itis piceous black, with the disk of the thorax of a bluish cinereous 
tinge, the remainder of the thorax being presumably black as 
are also (presumably) the antennae. 
The only other two species recorded are P. wulpt, Kert. 
(Termes. Fuzet., xxii, 179) and P. argyrogyna, Meij. (Tijd. Ent., 1, 
257,07 2, pl. vi, 23, wing).
