17. Papilio demoleus, Linn. (o07 Bing.). Exceedingly common for the 

 greater part of the year. It becomes scarce only for a few weeks during 

 the very hot and tho very cold months. 



18. Papilio p<i/i/tex, Linn. {—P. jmmmon, Linn.). (522 Bing.). Males 

 appear about the time the first monsoon rains fall in July and gradually 

 become common. Females are usually much later, seldom being in 

 evidence before late August. The brood seems to die out by the end of 

 October, though a few ragged specimens may sometimes be seen as late as 

 the third or even fourth week of November. 



PlERID.E. 



A familj^ more strongly represented than any other in this part of the 

 Punjab. The species are fairly numerous and individuals of most are 

 common, so that a large proportion of tho insects to be seen at any time 

 are always of this family. It is only during the blazing hot and hazy 

 weather of late May and June, when hardly a butterfly is to be seen, that 

 these whites are scarce. 



19. Delias euc/iaris, Drury. (571 Bing.). I took a very battered speci- 

 men in August 1916 — ^the only one seen during the four years. The species 

 is common to the south-eastward and may yet extend more freely into the 

 district in years to come. 



20. Anaphms mesentina, Cramer. (581 Bing,). One of the most abun- 

 dant butterflies seen in and around Lahore during the cold weather. 

 It appears about November and is common everywhere till February or 

 March, may be seen in thousands in the scrub bushes alongside the 

 Railway. 



21. Pieris brassicce, Linn. (590 Bing.). Another cold weather insect. 

 Appears in November and is common during the few weeks following. 

 Partially disappears in the very cold weather, to come ovit again for a short 

 time in January and February. 



22. Huphina phnjne, Fabr. (604 Bing.). This dry tract form of H. 

 nerissa, Fabr., is occasionally taken, but is rarer than might be expected. 

 It is probably overlooked by reason of its general resemblance, when 

 flying, to the more common A. mesentina. 



23. I.iias marianne, Cramer. (608 Bing.). Very rarely in the monsoon 

 months, July to September. There seems to be no reason why it should 

 not be more plentiful. 



24. Appias libijthea, Fabr. (610 Bing.). A few may be seen, usually 

 in the period between the end of the rains and the setting in of the cold 

 weather. Never common, but it is possible that a superficial likeness to 

 othwr Pierids results in their being overlooked. 



25. Catopsiliacrocale,G-s:&T[nev. (622 Bing.). Both this and the variety C. 

 catilla, Cramer, are common throughout the monsoon and autumn months 

 when it swarms round the flowers of the Duranta. A few may be seen 

 during the winter and early spring, but it is never common after October. 



26. C'atopsilia pyyanthe,'L\iin. (623 Bing.). 



27. Catopsiliajlorella, Linn. (624 Bing.). 



Both of these are common, appearing about the same time as C. crocale, 

 but in special abundance just after the rains. 



28. Colias fieldi, Menetries. (638 Bing.). Not uncommon in the early 

 cold weather months. Is also to be seen in February and March. 



29. Tei-ias libythea, Fabr. (640 Bing.). A few may generally be taken 

 in October-November. The species was unusually abundant for a short 

 period in the autumn of 1914. 



30. Terias Upta, Boisduval. (641 Bing.). Only one or two have actually 

 been taken, in October after the rains, but the species is probably more
