gregarious. The larvae spin a joint feeble web, and lie together in 

 communities of ten or more. They feed at night only. Colour when 

 full-grown dirty brown, head black, Each segment with a dorsal longi- 

 tudinal dark brown stripe ; the larva is thinly covered with weak 

 white hairs. Just before pupation the colour turns to a light green, 

 with the head and stripes as before." 



234, Aporia agathon, G-. R. Gray. 



In de Niceville's collection is a single quite typical male example 

 of this species taken at Mussoorie in May. It is a noteworthy fact 

 that three such closely-allied species of the genus should all fly 

 together in the station of Mussoorie. It is the darkest coloured of the 

 three. 



235. Pieris canidia, Sparrman. Plate V, Fig. 21, pupa. 



Common both at Mussoorie and in the Dun almost all the year round. 



236. Pieris brassic^e, Linneeus. 



Very common both in Mussoorie and less so in the Dun in March, 

 but not found in any great numbers later in the year, although an 

 occasional specimen may be seen in almost every month. In gardens 

 in Mussoorie in the spring the larva does great damage to cabbages 

 (Brassica campestrisj L., var., Natural Order Cruciferce), so much so 

 that boys have to be continually employed in picking them off. 



237. Pieris melete, Menetries. 



Occurs sparingly in Mussoorie in May and June, and a few ragged 

 specimens have been brought in by collectors from the Nila and 

 Bhilung Valleys in July and August. 



238. Parapieris callidice, Esper. 



Found in our area at high elevations only far in the interior near 

 the snows, in tho Nila and Baspa Valleys, and from the Nilung 

 village, all at about 12,000 feet elevation, in the months of July and 

 August. 



239. Belenois mesentina, Cramer. 



Rare in Mussoorie in May, taken on Nag Tiba at 10,000 feet eleva- 

 tion in November, very common throughout the warmer months and 

 the autumn in Dehra Dun. 



240. Huphina nerissa, Fabricius. 



More generally known in India as H. phryne, Fabricius, and so 

 recorded from " Landoor " by Butler. Rare in Mussoorie ; very com-
