60. Rapala okseis, Hewitson. 

 Decidedly rare. Only one female taken in Lucknow, in November. 



61. Rapala melampus, Cramer, 

 Is not common but a few may generally be taken every winter. Is fond of 

 Chrysanthemum flowers on which I have taken nearly all my Lucknow 

 specimens. 



62. ViRACHOLA isocRATES, Fabricius. 



I have one specimen which I doubtfully identify as this species, taken in 



Lucknow in the early spring. It is unfortunately a broken and faded insect, 



but agrees in outline and general colouration with the description given by 



Mr. de Niceville. The epecies should occur in Lucknow but is probably rare.* 



FAMILY— PAPILIONID^. 



Sub-Family — Pierin^. 



This sub-family is represented by sixteen species, most of which are very 

 numerous in individuals. 



63. Delias eucharis, Drury. 



Occurs more or le?s throughout the year, occasional specimens being 

 seen in the early mornings of even the hottest months of the year. It is 

 most common during the autumn and winter when scores may usually be seen 

 on the flowers of the Duranta or among the branches of high trees. 

 64. Catopsilia CROCALE, Cramer. 



May almost be considered the most common Pierid of the district as it occurs 

 in great numbers right through the rains and well on into the cold weather. 

 The females vary greatly but are, as a rule easily distinguishable as one or 

 the other of two types. In the first or ordinary form the ground colour is a 

 distinct yellow, deepening towards the base, and the black mavginal and 

 other markings are clearly defined and comparatively narrow, the underside 

 being like that of the male. The second and somewhat rarer type has a 

 ground colour of creamy white with very broad black apical and marginal 

 markings, the exterior margins of both wings having a series of circular spots 

 somewhat more yellowish in tint than the ground colour, while the bases of the 

 wings are suffused with dusky. The underside has a distinct pearly sheen with 

 hardly any traces of yellow. Both forms occur concurrently in Lucknow. 

 65. Catopsilia catilla, Cramer. 



This, generally considered a dimorphic form of the last, is equally 

 abundant. The variety with the dark purplish blotches on the underside is 

 comparatively rare, but may sometimes be taken when the rains are well over. 

 66. Catopsilia pyrantue, Linnseus. 



Another very common species, occurring everywhere almost throughout the 

 year, but most frequently seen during the rains and cold weather. The female 

 is much more seldom met with than the male. The dry season form, C. gnoma, 

 Fabricius, replaces the monsoon type, the true C. pyranthe about October. 



* Fote.— Since the above was written, I have (July) taken a female F. tsocraies in ex- 

 cellent condition in Luukaow.
