Baccha dispar, Walk. 
A @ specimen in the Indian Museum, without data, identi- 
fied by Bigot, is certainly this species. 
Baccha robusta, mihi. 
Three (@ 2) have been seen by me from Dehra Dun, sent by 
Dr. Imms; one @ in the Indian Museum from the base of the 
Dawna Hills, 4-iii-o8 [Annandale]; and four (¢” ¢) from Sikkim, 
v-IQI2. 
Baccha flavopunctata, mihi. 
The specimens referred to in my description of this species, 
with the exception of the type, appear to be a different species, 
which is here described as elegans. 
Of true flavopunctata further specimens have been acquired 
from Sibpur, Bengal, 4-iv-13 [Gravely]; Cherrapunji, Assam, 4400 
ft., 2—-8-x-14 [Kempj; with an additional apparently immature 
one from the same locality. All are females. 
It is possible that this species is synonymous with fedicillata, 
Dol., though that author’s species is described as blackish brown 
with two semilunar pale bands; and mine as yellowish with black 
bands on the 3rd and 4th segments. Two specimens in the Indian 
Museum from Sibpur, Bengal, have the ground colour brown and 
the black bands a little larger and more extended at the sides of 
the abdomen, thus making a very close approximation to Doles- 
chall’s figure. 
His description agrees exactly, except that he does not men- 
tion the conspicuous perpendicular yellow stripe on the meso- 
pleura, with the adjoining spot on the sternopleura. His ‘‘ meta- 
thorax luteo cincto’’ may refer to the conspicuous elongate yellow 
spot on the metapleura. 
The specimens of this species with conspicuous yellow abdo- 
mens must bear some resemblance to vespaeformis, Dol. Flavo- 
punctata differs from Doleschall’s species by the presence of the 
metapleural and sternopleural yellow spots; by the black band 
at the base of the 3rd abdominal segment ; the black rings on the 
hind legs and the blackish subcostal cell. Doleschall says the 
wings are clear except for a brownish red fore-border. There is 
little doubt the two forms are distinct. In the four examples pre- 
sent of flavopunctata, two (including the type) have the ground 
colour of the abdomen yellow, in the other two it is brownish, 
and in these the shape of the abdomen is also slightly different, 
the breadth of the 3rd, 4th and 5th segments being greater, and the
