Il8 CATALOGUE OF BURMESE BUTTERFLIES 



262. P. DESCOMBESI, Boisduval. 



Very common from March till December. On one occasion 

 I came across this insect in great profusion at its breeding 

 place at the beginning of May in a forest near Kaukareet on 

 the Yonzaleen River. I found larvae, pupae and imagines, 

 the latter in the act of laying eggs, at the same time in the 

 same place. 



263. Prioneris thestvlis, Doubleday. 



Three specimens of the wet season form were taken by me 

 in March and April on the Lampha Choung, near Taoo ; and 

 two specimens considerably smaller, and with fewer dark 

 markings, were taken in February at Tounggya Sekkan, also 

 in Tenasserim. These are the dry season form which was 

 described by Hewitson under the name of Watsont. 



264. P. clemanthe, Doubleday. 



Male taken in Moulmain and Tenasserin districts, but not 

 commonly, in February and March. I have not taken a 

 female. 



265. Appias hippoides, Moore. 



Both males and females are exceedingly common. There 

 are two distinct forms of females which, however, are con- 

 nected by intermediate forms. In one form the under side of 

 the hind-wing of the female is similar to that of the male; 

 while in the extreme of the other form it is dusky-white, 

 gradually darkening towards the posterior margin and with 

 all the nervules fuscous. In a large series the gradations of 

 the two forms can be clearly traced, and they are probably 

 seasonal or climatic. 



266. A. zelmira, Cramer. 



I have a very large series of this species, both males and 

 females. The form Zelmira appears in the rainy season and 

 changes imperceptibly, as the cold and dry seasons follow 

 each other, into the form formerly known as A. irvinii. In 

 my series of many males and females, although I have 

 extreme forms of each variety, yet, it is quite impossible to 

 divide the two when a large number are seen together. I
