46 LEPIDOPTERA INDIGA. 



the ground, no other markings whatever, altogether a very plain-looking creature. 

 The constrictions at the segments shallow, the spiracles black, but inconspicuous, the 

 usual extensile organs on the twelfth segment very short. The larva feeds on the 

 yellow pea-like flowers and on the pods of Crotalaria striata, D.C., in Calcutta. 

 Dr. A. Forel, of Geneva, has identified the three species of ants which I have found 

 attending this larva in Calcutta as Camponotus ruhripes, Drury [sylvaticus, Fabricius), 

 sub-species CO mjtjressM.s;, Fabricius ; Ta.pinoma melanocejjhalum , Fabricius, and Prenolepis 

 obscura, Mayr. (var. clandestina, Mayr). 



Pupa. — Pale yellowish-gi'een, the posterior end very blunt and rounded, the 

 abdominal segments larger than the anterior, the head small, a dark dorsal line, a 

 double sub-dorsal series of small black spots, the thorax slightly humped on the back, 

 the pupa smooth throughout (de Niceville). 



Lang's description of the larva in Europe is somewhat different, and so also is 

 Trimen's description of it in South Africa, they are both given in detail by de Niceville, 

 at p. 205 of his work ; he says, " I have given these various descriptions of the trans- 

 formations of P. hoeticus, as from them it would appear that the insect is much more 

 variable in the earlier portions of its history than it is later on as a butterfly. I 

 think this will be found true of very many of the larvae of the Lycsenidse, which, as 

 far as my experience goes, vary in coloration and markings in the most extraordinary 

 and puzzling manner." 



Habitat. — All India, Burmah, Ceylon, the Malayan sub-region to Australia, also 

 in parts of Europe, Asia and Africa a very common insect.
