222 Records of the Indian Museum. [Vox.. XI, 
femora and a broad apical band on tibiae, neither of the rings 
very definite, tarsi wholly yellow. 
Wings clear; subcostal cell wholly blackish brown, and beyond 
tip of cell the colour spreads into an apical wing spot, contiguous 
to front margin and limited posteriorly by the 3rd longitudinal 
vein. Halteres brownish yellow. 
Described from a single ¢@ from Bhowali, 5700 ft., vii-og 
[Zimms], the specimen presented by him to the Indian Museum. 
This might easily be taken for the 2 of elegans, but a good 
structural difference exists. In apicenotata the antennae are seen 
to be set on a rather conspicuous prominence, and the facial bump 
is also distinct, but in elegans there is no obvious antennal promi- 
nence and the facial bump is barely noticeable. Other differences 
consist of the absence of the yellow stripe on the metapleura, 
the wholly blue scutellum, the wholly yellow hind metatarsus and 
the more conspicuous wing-tip spot. 
There are two further examples in the Museum collection 
which are apparently additional 9 @ of the present species. The 
differences in the first are: (1) the frons is a little broader, (2) the 
abdomen enlarges very suddenly at the base of the 3rd segment 
and reaches its greatest width at the tip of that segment. The 
abdomen is black, except for the Ist segment, the extreme base 
of the 2nd and (indistinctly) the basal half of the 3rd. The black 
streak on the costa reaches the tip of the 3rd vein, but only weakly, 
and shows no sign of enlargement into an apical spot as in 
apicenotata. ‘The specimen is from ‘‘ Jungle at base of Dawna 
Hills’’, r-iii-o8 [Annandale]. 
The second specimen is an obviously immature one from 
Cherrapunji, Assam, 4400 ft., 2—8-x-14 [Kemp], and differs only 
in the wholly clear wings. 
Baccha plumbicincta, mihi, sp. nov. 
Q Assam. Long. 84 mm. 
Head.-——Frons broad, distinctly but not greatly broader above 
antennal prominence, where it is nearly one-fourth the width of the 
head ; bluish black, the colour sharply demarcated behind vertex; 
a little whitish tomentum about the middle of inner orbit of eyes. 
Face, down to a little above mouth opening, bluish black, slightly 
grey-dusted, with a central conspicuous black bump. Remainder 
of lower part of head, including buccal region, uniformly bright 
yellow. Antennae black, 3rd joint broad, arista black. Occiput

Thorax.—Dotrsum and scutellum almost lead colour, shining, 
with slight coloured reflections when viewed from different angles ; 
minute yellow pubescence; remainder of thorax bright yellow. 
Abdomen.—Only slightly contracted on 2nd segment, remain- 
der of segments barely wider, the abdomen at no point quite so 
wide as thorax, shining bluish black with very short inconspicuous
