Purreea : Tilin, December to February. 



193. Terias sari, Horsfield. 



Pauk to Tilin, November ; Tilin, November to February. 



194. Terias venata, Moore. 



Pauk, November. A single specimen. 



195. Ixias pyrene, Linnaeus. 



I obtained altogether fifty-six specimens, which, though 

 probably all of the same species, were of four distinct 

 forms easily separable by the markings on the underside 

 of the hindwing. 



Variety a : Ten specimens of a large form, with the 

 underside clear yellow moderately striated with brown ; 

 and with three to six brown ocelli on hindwing. This 

 form occurred at Tilin in December, January and March, 

 being commonest in March, 



Variety b : Seventeen specimens of a much smaller form, 

 also with clear yellow underside, with few striations and 

 three or four brown ocelli with white centres. This form 

 occurred at Pokoko in September and October, and at 

 Tilin in April, being commonest in the former months. 

 Variety c : Twelve specimens of a form of the same size 

 as the last, also with a clear yellow underside, but abso- 

 lutely without striations, and with no trace of ocelli. 

 This form occurred at Pokoko in September and October, 

 at Pauk in September, and at Tilin in April and May. 

 Variety d : Seventeen specimens of a form with an orange- 

 yellow underside densely striated, and with a varying 

 number of ocelli. This form occurred at Tilin in January 

 and February only. Varieties a and f/are presumably dry- 

 season forms and b and c rainy-season forms. If that is 

 the case the dry-season forms have the underside of hind- 

 wing more densely striated than the rainy-season ones. 



196. Catophaga Ubythea, Fabricius. 



Tilin, January. Five males which Mr. de Niceville consi- 

 ders may po ' \\ be the dry-season form of this species.
