THE BUTTERFLIES OF MUSS00R1E. 371 



79. Neptis susruta, Moore. 



We have a single specimen taken in Mussoorie on 15th June, 1888. 



80. Neptis yerbtjmi, Butler. 



Very common at Mussoorie and Nag Tiba from March to Juno, 

 and again in September; we have a single specimen from Dehra 

 Dun taken in March. The larva feeds in Mussoorie on Celtis auslralis, 

 L., Natural Order Urticacece. 



81. Neptis mahendra, Moore. 



Rare in Mussoorie at 7,000 feet elevation in April and May; very 

 plentiful at Nag Tiba in May and June. 



82. Neptis columella, Cramer. 



The largest species of Neptis occurring in our area, and found only 

 in the Dun rarely from March to May. This species was originally 

 described from China, and at last de NiceVille has obtained both sexes 

 from thence (Hongkong). They are, in his opinion, identical with 

 Indian specimens, consequently the N. opliiana of Moore, the -N. marta- 

 bana of Moore, the N. ophiana, var. nilgirica of Moore, and Acca 

 columena of Hiibner, fall as synonyms. 



83. Pseudergolis wedah, Kollar. Plate U, Figs, 9a } larva ; 



9b, front view of head of larva ; 9c, 9d, 9e, 9/, pupa. 

 Very common during the summer in and near Mussoorie, where 

 it is probably triple-brooded, but not found in the Dun. The larva 

 feeds on the leaves of Debregeasia bicolor^ Wedd., Natural Order 

 Urticacece, is dark green, with two long diverging branched spines or 

 horns on the head, and two simple upright spines on the subanal 

 segment. Mr. Mackinnon thus describes the larva : — " Found in 

 August on ' Siar,' a very common plant on which the larva of Pareba 

 vesta, Fabricius, also feeds. Length one and three-eights inches, bright 

 dark green, all the segments except the head minutely spotted with 

 white, these spots or tubercles are arranged in transverse rows, each 

 segment having two rows ; a dorsal protuberance on the fifth segment ; 

 two sharp black spines on the eleventh segment; the base of the spines 

 pale greenish-blue ; two divergent horns on the head, five-sixteenth of 

 an inch long, yellowish- green, with six shining black lines on each horn, 

 tips of horns shining black ; the line dividing the dorsal from the 

 Ventral aspect of the body creamy- white. The leaf of D, bicolor is 

 much crinkled, as also is the skin of the larva, it so is ^difficult to be©
