1136 JOURNAL, BOMBAY NATURAL HIST. SOCIETY, Vol. XXI. 



A very common insect, found almost everywhere and a fast, strong flier ; 

 somewhat variable according to season and locality. 

 Larva normal, green ; pnpa of the Anaphcsis type. Foodplant Capers. 



Genus Ixias. 



A. Upperside : ground-colour clear gamboge-yellow. 



Size : l"-70 to 2"- 50 pyrene. (PI. J. 



figs. 65 S , 65a 



B. Upperside : ground-colour white. 



a. Forewing upperside : preapical orange patch ex- 



tended into apex of cell. Size : 2"-l to 2"*6 . . marianne. (PL 



J. fig. 62.) 



b. Forewing upperside : preapical orange patch not 



extended into cell. Size : 2"- to 2'''2 . . . . nola. 



These are "Orange-tips." Nola is probably only a variety or local 

 race of marianne as the character of extension of the orange patch is not a 

 good one ; it is only found at Mahablesbwar on the Western Ghats. The 

 ground-colour of pyrene female may be almost white, though never pure 

 white, and may have no orange patch though the black border defining 

 that patch is always present. 



Larva green ; pupa of the Anaphmh type. Foodplant Capers. 



Genus Appias. 



This is an extremely difiicult group to disentangle as the individuals 

 vary so much with the season and locality in the amount of markings on 

 the wings ; some specimens, indeed, of one species which is normally white 

 may be suffused strongly on the underside with yellow or orange. The 

 forewing of the male is nearly always rather narrow and pointed. 



A. Forewing : veins 5 and 7 approximate at bases and, 



therefore, the top discocellular vein missing ; the 

 upper discocellular (veinlet uniting veins 6 and 6) 

 less than half the length of the lower discocellular 

 veinlet (uniting veins 4 and 5). 

 a. Male forewing underside : discal black band narrow; 

 hindwing not richly coloured underneath in wet- 

 season form. Size : 2" to 3" . . . . . . indra. 



h. Male underside forewing : discal black band broad ; 

 hindwing underneath richly coloured in wet- 

 season form. Size : 2"-3 to 2"-75 . . . . narendra. 



B. Forewing : veins 5 and 7 approximate at bases ; top 



discocellular more than half length of lower dis- 

 cocellular. 

 a. Upperside forewing : outer black margin or area not 

 produced inwardly in interspace 3.
