626 MR. H. J. ELWES ON BUTTEKFLIES FROM [DcC. 6, 



Nacaduba aberrans, n. sp. (Plate XLIV. 6g. 6, cJ •) 



A single male specimen was sent from East Pegu, with the 

 following note by Mr. Doherty : " Nacaduba sp., in appearance a 

 Catockri/sops. Petichaung low country." 



It may be described as follows : — 



Size, shape, and colour above of a small specimen of N. atrata, 

 Horsf. Below paler, the two inner bands of the fore wing short, 

 the outer bands more lunulate, the anal ocellus nearly as large as 

 the one above it and showing plainly on the upper surface ; tails as 

 in atrata. It is unlike any other species known to me or mentioned 

 in the ' Butterflies of India.' I have also four males, all taken by 

 Doherty in Car-Nicobar Island some years ago, which agree with the 

 type exactly, though the blue of the upperside is somewhat faded. 



Jamides bochus.

 Sent from the Naga and Karen Hills and Perak.

Lampides Tcankena, Butt. Ind. iii. p. 1/4. 



Specimens from Perak agree with those from tbe Andamans 

 which pass under this name, and are hardly separable, as far as I 

 can see, from L. elpis, though usually much smaller and having the 

 black border of the fore wing in the male very narrow. 



Lampides coruscans. 



Lampides coruscans, Moore, Ann. N. H. (4) xx. p. 341 (1877); 

 Butt. Ind. iii. p. 163. 



Specimens from Perak, 7 males and 3 females, are constant in their 

 deep blue colour, and seem to be quite easy to separate from all 

 forms of L. elpis, though the markings of the underside agree.
