PIERINuE. 191 



Laeva. — " Colour dull blue-green. Head and all the segments closely dotted 

 with minute blue tubercles, those on the head and sides black tipt ; dorsal surface 

 pubescent; a lateral fringe of soft white hair below the spiracles. Feeds on 

 Gapparis." 



Pupa. — " Bright green. Sharply pointed at the head ; with two strong lateral 

 points and keeled on dorsal surface of thoracic segments ; an interrupted yellow 

 lateral line, and a short curved crimson line on each side just below thoracic 

 segments bordering a small white irregular black speckled spot " (E. B. Green, MS. 

 Note, July, 1886). 



Habitat. — Ceylon ; S. India, 



Distribution. — In Ceylon, Mr. F. M. Mackwood says this species occurs in the 

 " Hills from 2,000 to 6,000 feet elevation, and is compai'atively scarce " (Lep. 

 Ceylon, i. 141). Mr. L. de Niceville records it as "fairly common in Ceylon at 

 moderate elevations. Dr. N". Manders has taken it in Punduloya in January, and 

 has noted its occurrence, amongst other places, at Haputale, 5,000 feet, Koslande, 

 2,500 feet, Behilul, 2,200 feet, and Wellaway, 500 feet. It is a splendid mimic in both 

 sexes of the highly protected Delias EucJiaris, Drury, but its more rapid and some- 

 what darting flight makes it easily distinguishable when on the wing ; the acutely- 

 pointed apex of the forewiug is also a noticeable feature even in flight. The female 

 is very rare " (Journ. As. Soc. Bengal, 1899, 210.) In the British Museum 

 Collection is a male from Kandy taken in July by Col. J. W. Yerbury. 



Of its occurrence in the Kauara District, South India, Messrs. Davidson, Bell, 

 and Aitken write, " It cannot be distinguished from Delias Eucharis on the wing, 

 unless a very close and clear view is obtained ; so doubtless we have seen more than 

 we know, but we have only caught seven specimens in all. Of these, two were 

 caught at the Gairsoppa Falls, or on the way to them, but we know that it occurs as 

 far north as Karwar" (I.e. 1896, 570). Mr. T. R. Bell "has seen a female laying 

 eggs on a plant which is probably Capjxiris tenera. The eggs hatched out, but the 

 larva failed to reach matui'ity " (J. As. Soc. Beng. 1900, 270). A male labelled 

 "Nilgiris" is in Mr. P. Crowley's Collection. 



Mimicry. — " This butterfly is a splendid mimic of the highly protected Piccarda 

 Eucharis, but its more rapid and somewhat darting flight makes it easily distinguish- 

 able when on the wing " (L. de Niceville, J. As. Soc. Beng. 1899, 210).
