COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 1145 



swollen about segments 3, 4 with a spiracular line of irridescent tubercles : 

 Sebomoia. 



Larva normally cylindrical all along, green or yellowish green, a white 

 spiracular band and transverse rows of black tubercles to each segment, 

 those immediately above the spiracular band generally more or less strong- 

 ly developed forming a black supraspiracular band : Catopdlia. 



The larva again of Leiitoda might be separated off from Terias-Colotis 

 by the fact that it is smaller and slighter than them ; but such classifica- 

 tion is useless. 



The second group having angulated chrysalides may be subdivided to a 

 .certain extent as follows : 



Larva not green : Anaphceis, Delias. And again these may be known : 



Larva light brown : Delias. 



Larva ochreous and purplish brown in longitudinal bands : Anaphoeis. 



Larva green of some shade : Piioneris, A^ipias, Huphina, Colias, Pieris 

 'These being insufficiently known it is impossible to further distinguish 

 them at present. 



The food-plants of the members of the family are various though all 

 {leaving out Pieris, Colias, Synchloe) belong to the Leguminoscs, Capparidece, 

 ■Salvadoracece : Loranthacece, Eupliorhiacem, as follows : 



Leguminosece : I'erias, Catopsilia. 



Capparidece : Leptosia,'' Pareronia, Prioneris, Lvias, Anapliceis, Huphina, 

 <Colotis, Appias (except Appias loardi). 



Loranthacece ; Delias. 



Euphorbiaceoe : Appias ivardi. 



Salvadoracece -. Coloti--^. 



Most of the larv« that feed upon Capers will feed upon any Caper ; 

 Terias will also feed upon nearly any leguminous plant ; Catopsilia is 

 nearly confined to the genus Cassia but will feed upon most of the species 

 of that genus. 



87. Leptosia xiphia, — Upperside : white ; base of wings very slightly 

 powdered with minute black scales. Forewing : costa speckled obscurely 

 with black, apex black, the inner margin of this inwardly angulate ; a very 

 large, somewhat pear-shaped, postdiscal spot also black. Hindwing: white, 

 uniform ; in most specimens an obscure, extremely slender, terminal black 

 line. Underside : white, costal margin ; and apex of forewing broadly, and 

 the whole surface of the hindwing irrorated with transverse, very slender, 

 igreenish strigoe and minute dots ; these on the hindwing have a tendency 

 to form subbasal, medial and discal, obliquely transverse, obscure bands ; 

 forewing : the postdiscal black spot as on the upperside ; terminal margins 

 of both fore and hindwings with minute, black, short, transverse, slender 

 lines at the apices of the veins, that have a tendency to coalesce and form 

 .a terminal continuous line as on the upperside. Antennae dark brown
