﻿222 LEPIDOPTERA IN DIG A. 



divergent similar processes on the twelfth segment, also two very short dorsal 

 spiny-tubercles on tlie third and sixth segment. Head cleft and pointed at the 

 vertex. Colour brownish-purple, anal segments dark purple-brown, spotted with 

 green, and bordering an oblique line extending laterally from anal spine to base of 

 spine on fourth segment ; two short oblique subdorsal anteriorly-oblique lateral 

 streaks along middle segments. (Described from Dr. Thwaites drawing in Lep. of 

 Ceylon, which was probably taken from a larva just previous to pupation.) In Mr. 

 E. H. Aitken's Bombay drawing (our figure 1) the colour of the larva is paler, 

 the dorsal area greenish with darker green oblique lateral stripes. 



Chrysalis. — " Suspended vertically ; abdomen slender, thorax much stouter 

 and broader, with sharp angular dorsal ridges ; wing cases expanded laterally ; 

 head-piece with two sharp points. Colour varying from dark brown to dull white, 

 suffused and tipt at points with gold " (Davidson and Aitken, Journ. Bombay Nat. 

 Hist. Soc. 1890, 273). 



Habitat. — Eastern and Southern India ; Ceylon ; Burma ; Tenasserim ; S, 

 Andamans. 



DiSTEiBUTiON. — " It is Very common in Calcutta ; the Indian Museum possesses 

 specimens from Cachar, Rangoon, Upper Tenasserim, Mergui, Orissa, Trevandrum» 

 Ceylon, and South Andamans" (Butt. Ind. ii. 107). We possess specimens of 

 both sexes from Malabar ; Travancore, taken in April ; Cejdon (Trincomali and 

 Kanthalla) ; Rangoon ; Mergui ; S. Andamans. Mr. Wood-Mason records two males 

 taken at " Silcuri, Cachar, in June and July " (J. A. S. Beng. 1886, 357). Mr. 

 G. F. Hampsou found it " not uncommon in the Nilgiris, from 8000 to 5000 feet 

 elevation" (J. A. S. Beng. 1888, 353). Mr. H. S. Ferguson records it as "fairly 

 common in the low country of Travancore, and up to 3000 feet in the Hills " 

 (J. Bombay N. H. Soc. 1891, 8). In Ceylon, Capt. Hutchison says, it is " found in the 

 Western and Central Provinces ; both in the plains and up to 4000 feet elevation, in 

 forest land, at all times, but chiefly during the S.W. Monsoon. Mr. F. Mackwood 

 records it occurring everywhere in Ceylon ; February and March in fair numbers. 

 Joins the np-country flights " (Lep. Ceylon i. 55). Col. J. W. Yerbury obtained 

 it on the Kandy road in October, and at Kanthalla in October, also at Trincomali 

 in October and November. 



In Burma, Col. C. H. E. Adamson records it as " common on the Arakau 

 coast in the cold season " (List 1897, 21). Dr. J. Anderson took it in the Mergui 

 Archipelago, at " Minthantoung, December, and Elphinstone Island in March " 

 (J. Linn. Soc. Zool. 1886, 36). 



Food-Plants of Lakva. — According to the observations of Messrs. J. Davidson 

 and B. H. Aitken, the larva " is a most promiscuous feeder. We found it in the 

 Kanara District, Bombay, on Helicteris hora, Grewia microcos, Zizijphus nujosa.
