except in the absence of a tail. The occurrence likewise 
of the tailless form of Nacaduba ardates in those districts 
is worthy of remark.”

Spalgis epius, Moore, Lep. Cey., p. 71, t. 34, figs. 1, 1a, b. 
Found in the lower valleys, but not common, between 
the months of May and October. 
241. Cyaniris puspa. 
Polyommatus puspa, Horsf., Cat. Lep. E. I. C., p. 67 
(1828). 
This species is variable on both surfaces, but, as 
restricted by de Nicéville and Moore, is perhaps the 
commonest at low elevations, and distinguished by the 
darker, more numerous and irregular markings of the 
under side. Moller notes it as found from 1 up to 
10,000 ft. It has a wide range in India. 
Mr. Moller writes, in May, 1886 :—‘“‘I have, during 
the month of March last, received specimens of the 
above species of this group, viz., C. alboceruleus, trans- 
pectus, marginata, placida, dilectus, jynteana, and puspa, 
and am perfectly satisfied that they are all good and 
distinct species. C. transpectus, marginata, and puspa 
vary a good deal according to season, the broods occur- 
ring during the rainy season having a broader dark 
margin to both the wings, and all the spots on the under 
side better developed, whilst specimens taken in spring 
and autumn are characterised by a paler coloration and 
diffused patches of white on both wings.” 
242. Cyaniris marginata. 
Cyaniris marginata, de Nicé., J. A.S.B., March 6th, 
1883, p. 70, t. 1., fig. 9, ¢; Moore, P. Z.8., April 
1st, 1883, p. 523, t. 48, fig.6; Doherty, J. A S.B., 
1886, p. 134, 2. 
I was inclined to unite this form also with C. puspa, 
as the broad dark margin, which is supposed to dis- 
tinguish it, is a variable character. Doherty, however,
