the pair, and forming the lower stroke of the Y of which they are the upper arms. Thus, 
L. coruscans appears to be a form of Z, e/fis in which the tint of the upper surface is decidedly 
deep azure-blue, and which is, moreover, of a smaller size. I possess a male specimen 
of this species from Ceylon, one from the Chittagong Hill Tracts, two from Teressa (one 
of the Nicobar Isles), and one from Singapore. It may be that these specimens represent a 
form not really specifically distinct from Z. e/pis, but the species may be retained as such at 
present, pending the results of further local research and experience. 
In Ceylon Z. coruscans is “ Plentiful in the Kottawa forest, Galle. Easy to capture” 
(Wade). “ Western and Southern Provinces. Plains, in forest land ; during S.-W. mon- 
soon, fluttering about bushes in open glades of the forest ; not common ” (Hutchison). 
In the Phayre Museum, Rangoon, is asingle male from Palone, in Burma, taken in January, 
which measures a good deal more than the above-noted specimens ; it also differs in its still 
darker tone of colour on the upperside, and the black margin is considerably diffused 
over the apex and outer margin of the wing. 
Mr.- Distant records Z. hamtkena, Felder, from the Malay peninsula and Borneo, and 
places the Cupido cerulea of Druce as a synonym of that species. The original descrip- 
tion of the latter species is so inadequate and the figure is so obviously incorrect that without 
reference to the type specimen it is impossible to exactly determine the species. It appears 
probable, however, that it is very near to or perhaps synonymous with Z. coruscans, Moore 3; 
in the latter case Z. c@rulea would have priority. But Mr. Distant must be mistaken in 
saying that Z. kankena and L. c@rulea are one species, and that the former occurs in the Malay 
peninsula, as Dr, Felder describes Z. kankena as ‘‘ Male. Upperside pale silvery-blue,” 
z.é., of the @lianus group Mr. Distant decribes it as ‘‘ Male. Upperside dark, shining, 
azure-blue, ” z. e., of the e/f7s group, and apparently of the exact shade of Z. coruscans. 
There can be hardly any doubt that Mr. Distant. has wrongly identified this species, more 
especially as he does not record the true Z. coruscans from the Malay Peninsula, where it 
undoubtedly occurs. Mr. Butler records Z. cerulea from Ceylon, no doubt quite correctly. I 
give below Mr, Distant’s description of it with its synonomy as set down by him, and also 
Mr. Druce’s description of Z. cerz/ea.*

1 have hardly any doubt in my own mind that the ceru/ea of Druce, the coruscans of Moore, and the 
kankena of Distant (but not of Felder} represent but one species, which should be known by the first mentioned 
name, but until someone makes an actual comparison between the type specimens of all these species, the matter 
must remain in doubt.
