W. Doliorty — No/es on Assam Butlerflies. 



[No. 1, 



A single female, near Margberita. It is very large — about three and 

 a half inches in expanse. The hind wing has almost no outer angle, the 

 forewiug has the outer uargin straight (rounded in verma, etc.) and the low- 

 er angle not cut away (as in hjrania). The last bifurcation of the median 

 vein of the hindwing takes place a little before the end of the cell. The 

 species has no near allies. Lethe margaritw, Elwes {Neorina* margaritm, 

 Marshall and de Niceville), which it apparently connects with the other 

 Leihes, obviously difEers in the white band of the hindwing below, and the 

 white scales diffused over the under surface. As in margaritce, the white 

 band of the forewiug is probably absent in the male.

 Dtctis pealii, Wood-Mason, PI. X, Fig. 3, 9 . Sadiya and Mar- 

 gherita. The female differs greatly from the male in this handsome 

 species. The tails are much longer than in the male — longer even than 

 in Ehjmnias caudata. Above, the wings are tinted with blue instead 

 of violet. Foreiving with the subcostal band very obscure, the coll dark, 

 the disc pale. Rindwing with a conspicuous rufous-orange anal spot 

 occupying the entire breadth of the submedian space, the violet submar- 

 ginal band of the male replaced by a short bluish fascia thenco to tho 

 large discal and apical pale area. Below, the entire forewing, except tho 

 cell and the outer margin, is clouded with large violet-white strire, and 

 so is the apical and part of the discal area of the hindwing. 



Family Moephid^. 

 ^MONA AMATHUSIA, Hew. {peaVii, W.-M,). ^. ^^eaZw appears to be 

 the wet-season form of amathusia, differing only in the less acute and 

 falcate forewing, the more distinct ocelli, and brighter colouring bolow, 

 the usual differences between seasonal forms in India. I took two 

 specimens of pealii near Sadiya in September. The outer margin of 

 tho forewing was convex throughout, but tho apex was slightly more 

 acute than in the type. On the first of December, I caught a single 

 ragged specimen of amathusia near Margherita, apparently quite 

 typical. 



* That species is of oonrsG a LetUe. Tho true NeoHnas aro siiijvnlar iusocta, and 

 can only be rotainod in the Sati/ridiv on account of tho difiicalty of putting tUum 

 anywhere else. I have often observed N. lawii in Borneo, tho Malay Peninsula, and 

 Eastern Java (where, however, the local repreaentatiTO may bo distinct). It is 

 continually changing its perch, flitting round and round the passers-by, and alight- 

 ing with the wings partly or wholly open. When flying, it has the strongest possi- 

 ble resemblance to Papilio helenus, and it may possibly bo advantageous for a 

 scarce, rather weak-flying insect of morphid or satyrid affinities to resemble a com- 

 mon Papilio of powerfnl and irregular flight.
