59. Zizera maha, Kollar. 



Lycsena maha, Kollar, Hiigel's Kaschmir, vol. iv, pt. 2, p. 422, n. 9 (1844) ; 

 Zizera maha, Walker, Trans. Ent. Soc. Lond., 1895, p. 460, n. 60 ; Lycsena bohemanni,

 Zool. Soc. Lond., p. 888, 1881) ; Plebeius albocseruleus, Rober, Iris, vol. i, p. 59, pi. iv, 

 fig. 7, male (1886). 



Dr. A. G-. Butler in Proc. Zool. Soc. Lond., 1900, p. 107, n. 3, pi. 

 xi, figs. 5, 6, male, gives Lycsena opalina, Poujade, with L. marginata, 

 Poujade, and Plebeius albocseruleus \_sic~], Rober, from Burma, Tibet and 

 China as distinct from Lycsena maha, Kollar, with Folyammatus chandala, 

 Moore, and Zizera ossa, Swinhoe, from Western India, occurring in the 

 Lower Himalayas to Madras [? Bombay] ; he also keeps distinct the 

 Lycsena diluta of Felder, with Lycsena squalida, Butler, from the Eastern 

 Himalayas southwards to Ganjam in the Madras Presidency. The 

 latter species was originally described from Cachar, so the province of 

 Assam must be added to the region of Zizera diluta. I am unable to 

 follow Dr. Butler in his division of the wide-ranging Z. maha into 

 three geographical races. No hard and fast geographical line can be 

 draWn between them, Z. maha occurring from Kashmir at least (and 

 probably still further to the west) on the west to Hongkong on the east. 

 In Calcutta the larva feeds on Oxalis, Natural Order Geraniacese.
