1915. | E. BRUNETTI: Notes on Oriental Syrphidae. 237 
Described from one @ in the Indian Museum from Onari, 
Garhwal Distr., 11,000 ft., W. Himalayas, 27-vi-14 (Tyiler). 
In connection with this species may be noted an interesting 
case of mimicry. C. imitator itself, in the pale pubescence on 
the anterior part of the thorax and on the scutellum, in the colo- 
ration of the abdomen, the black legs and grey wings, distinctly 
resembles the bee Bombus trifasciatus, Smith; but the protective 
resemblance accorded to a large Echinomyia-like Tachinid fly 
(though not belonging to that genus), 20 mm. long, by the simi- 
larity of its appearance to that of the bee, is even more striking. 
The pubescence of the fly is tolerably dense, black, except for 
a broad yellowish grey band on the anterior margin of the thorax, 
and on the scutellum. The apical third of the abdomen bears 
rather bright red pubescence. No strong bristles are present any- 
where, the eyes are bare, the antennae short, the 3rd joint much 
broadened vertically, notched at the truncate apex. Five speci- 
mens are present, taken in company with the Syrphid and one 
specimen of the bee. 
Lycastris cornutus, Enderl.

Type in Stettin Zoological Museum. 
SY RIT TA, ‘St; Fare: 
In my previous paper on Syrphidae my impression that there 
were only three Indian species of this genus was noted, and the 
further examination of a good number of specimens increases that 
impression. One of these is the common S. pipiens, L,., of Europe 
and North America which occurs commonly in the Himalayas and 
also more rarely in the Indian plains. One specimen is in the 
Indian Museum from Mergui. 
Of ortentatis, Macq.' and rufifacies, Big., I prefer to speak at 
present, as forms only, for two reasons. Firstly because there is 
primarily S. indica, Wied., to be disposed of as the earliest des- 
cribed oriental species; but as his description is so meagre, it is 
unidentifiable. Still he says ‘‘ very like pipiens, L.’’ from which 
_ it may be inferred that the hind femora are practically wholly 
black. Now in pzfiens there is normally a pale transverse streak 
in the middle, on the underside, which is often of considerable 
width and length, but which also is sometimes barely traceable, 
so that specimens may quite possibly occur which are practically 
wholly black. Wiedemann’s type, moreover, may have not been 
in the best condition so that the presence or absence of such a 
pale streak may not have been easily ascertained, nor, inciden- 
tally, considered of much consequence in those days. Therefore,
