is too inaccessible even for deer, which abound in the lower 

 altitudes where the formation is not limestone. 



Climate. — The rainfall is heavy, but not nearly so heavy as 

 in New Guinea, though there is great humidity. The tem- 

 perature was never noticed above 72° or below 58° Fahr. 

 In New Guinea at the same altitude we have had it down 

 to 49° Fahr. A lot depends on the wind. The North-West 

 Monsoon has now set in. This season, though rainy, is per- 

 haps the warmer season in the mountains, but it would be 

 necessary to stay a full year to obtain reliable results on this 

 question. We do not think that in New Guinea and Ceram 

 there is any marked butterfly season, though some things 

 are unquestionably rarer during some months than during 

 others. It will be clear, however, that it would require 

 permanent residence in one place to decide this point, as 

 nearly all things are to a certain extent local, and may be 

 common on one side of a bay and rare on another. It is 

 the same in the mountains, certain ridges having their common 

 and rare species. We have noticed no difference in species 

 on the various sides of the mountains as is so marked in 

 S. America. 



From May till September the South-East Monsoon blows, 

 and this is the " dry " season. That is to say, there is less 

 rain than during the North-West, which blows from October 

 till April. 



Hahils of Delias. — Around about our camp we have felled 

 the jungle in large areas, and men are placed in the trees on 

 the edges of the clearings. Generally speaking the Delias 

 males are only found in this way, and this will explain the 

 apparent comparative rarity of this sex in some species. The 

 females are generally taken either in sunny spots in the jungle 

 or flying over the ridges within reach. When the males come 

 over that way they are nearly always out of reach. One 

 magnificent species, undoubtedly new, does not seem to go 

 below 5000 ft. Curiously enough most of the females of this 

 species were taken at 6000 ft., and most of the males at 5000 ft. 

 We think it is a high species. On the wing the female is 

 remarkably like the South American pereute. This is due to 

 the black upper surface with a beautiful red or orange band
