126 CATALOGUE OF BURMESE BUTTERFLIES 



merely by the white rings surrounding the spot. Irrespective 

 of the season the colour of the upper side varies much, and 

 cannot be relied on in determining the species. I have one 

 specimen in vi^hich the discal row of spots on the under side 

 are elongated internally parallel to the veins. There was not 

 a day throughout the year when I was not able to find this 

 species in my garden. 



310. Z. LYSiMON, Hiibner, or karsandra, Moore. 



Very common at all seasons in Upper Burmah. Some 

 females are entirely brown on the upper side and some are 

 dusted with violet blue near the base. On the under side this 

 species varies in a similar manner to, though in a less degree 

 than Z. ?naha, Kollar, according to the season. 



311. Z. OTIS, Fabricius. 



This insect is excessively common all the year round in 

 Upper Burmah, and I have taken it plentifully in every month. 

 It also varies on the under side in a similar manner as Z. maha, 

 Kollar, and Z. lyswwfi, Hiibner. Sometimes during the dry 

 season the under side assumes a darker grey ground colour 

 and the spots can hardly be traced. The colouring of the 

 upper side in this species appears to be constant except as 

 regards the breadth of the dark margin, 



312. Z. GAiKA, Trimen. 



This insect in its habits more nearly resembles Fithecops 

 hylax, Fabricius, than the three preceding species. It is less 

 common, and appears to be subject to less variation than they 

 are. I have taken it at all seasons of the year near Sagaing. 

 It is most plentiful at the end of the rains. 



Note. — I do not believe that in Burmah there are more than the four 

 species of Zizera I have enumerated above. I have carefully noticed them 

 and caught them day by day in great numbers, and I am convinced that 

 the colouring of the upper wings varies at all seasons of the year. I have 

 also noticed that it is seldom that more than one species is very plentiful at 

 a given spot. 



313. AzANus gamra, Lederer. 



A very local insect in the Central Zone, though when met 

 with not uncommon. I have caught it in one locality near
