LKPTOSIA. DELIAS. 



139 



continuous line as on the upperside. Antennae dark brown spotted 

 with white, head slightly brownish, thorax and abdomen white.- 

 $ . Similar, the black markings on the upperside o the tore wing 

 on the whole slightly broader, but not invariably so. 



Exp. cf $ 25-53 mm. (1 -00-2-10"). 



Hob. The lower ranges of the Himalayas from Mussoorie to 

 Sikhim ; Central, Western, and Southern India, but not in the 

 desert-tracts ; Ceylon ; Assam ; Burma and Teuasserim ; extending 

 to China and the Malayan Subregion. 



Larva. " Green, with a pale glaucous tinge about the bases of 

 the legs and slightly hairy. Feeds on capers." 



Pupa. " Sometimes green, but oftener of a delicate pink shade* 

 Both the larva and pupa are very like those of Terias hecabe, but 

 more delicately formed." (Davidson, Bell $ Aiiken.) 



Mr. Moore has separated the Nicobar specimens under the 

 name nicobarica, but in a long series from nearly all parts of its 

 range I have found the characters relied upon for distinction 

 eminently variable.
