46 L. de Niceville — List of the Butterflies of Calcutta. [No. 1, 



56. Megisba THWAiTESi, Moore. 



A single specimen taken in February. It probably is often over- 

 looked owing to its close general resemblance to the species of the genus 

 Neopithecops, which often actually swarm amongst bushes in shade. 



57. JSTeopithecops gaura, Moore. 



58. Neopithecops zalmora, Butler. 



This species has never been properly characterized, and I am unable 

 to say in what particulars it is supposed to differ from N. gaura. At any 

 rate the species of Neopithecops occurring in Calcutta are exceedingly 

 variable, some specimens are entirely black on the upperside, others 

 have the costal and outer margins of the fore and hindwings black, all 

 the rest of the surface white, and there is every gradation between these 

 extremes. 



Mr. Moore writes to me — " N. gaura can be distinguished by its 

 broad white discal area in both wings of both sexes. iV^. zalmora has a 

 small discal white patch in the forewing only. I have both from the 

 Calcutta district." 



59. Curetis thetys, Drury. 



Not uncommon amongst trees and high bushes, it generally settles 

 ■with closed wings on the underside of a leaf out of reach. The female is 

 dimorphic, one form having the discs of the wings above white, the other 

 having them ochre ous. 



60. Chilades varunana, Moore. 

 Not common. 



61. Chilades laius, Cramer. 



Not common. It is synonymous with the G. kandura of Moore. 



62. ZlZERA KARSANDRA, Moore. 



Not common. 



63. ZiZERA DiLUTA, Felder. 

 Common everywhere amongst grass. 



64. ZiZERA SANGRA, Moore. 



Swarms amongst the grass at certain seasons. 



65. ZiZERA PYGM^A, Snellen. 

 Somewhat rare. 



66. Tarucus theophrastus, Fabricius. 

 Rare. 



67. Tarucus plinius, Fabricius. 

 Somewhat common. Very pugnacious. 



68. Castalius rosimon, Fabricius.
