ing conditions, which were presented by Mr. Marshall to the 

 Hope Collection in 1897. The statements made (loc. cit., 

 p. 209) with regard to the original seven are confirmed by the 

 new accessions, with the exception that the upper surface of the 

 male kept in normal surroundings is perhaps somewhat lighter 

 than that of the dry-heat male already in the Collection. The 

 under surface, however, of this male, and the general aspect of 

 all the females support the conclusion before arrived at that 

 the intermediate or early dry-season form of this butterfly can 

 be at least slightly influenced in the direction of the dry- or 

 wet-season phase respectively by artificial conditions of dry 

 heat and moisture. 



" (2) Three specimens of Pinacopleryx pigea, Boisd. 



" These three males are the specimens referred to by Mr. 

 Marshall (loc. cit., pp. 206-208) as d of the first series, and 

 g, k of the second series. Like the previous examples result- 

 ing from the same experiment, which are nine in number and 

 all females, they tend to show that under conditions of moisture 

 a certain approach is made towards the wet-season form of this 

 species ; this, however, is less conspicuous in the present group 

 of males than in the females just referred to. 



" (3) A male specimen of Teracolus anna', Wallgrn. 



" This specimen is spoken of by Mr. Marshall (loc. cit., 

 p. 201) as the one example which emerged out of two that 

 were kept as pupa? for nine days in a damp jar. The present 

 specimen shows a nearer approach to the full wet-season form 

 than the example in the Hope Collection which was left under 

 moist conditions for seven days instead of nine. It is, however, 

 less ' wet ' than another male bred at nearly the same time 

 under normal conditions (loc. cit., p. 202). In the case of this 

 species the numbers experimented with are probably too small 

 to warrant a definite conclusion as to its susceptibility. 

 "(4) A male specimen of Teracolus auxo, Luc. 



" This very interesting butterfly is the last of the three 

 individuals mentioned by Mr. Marshall (loc. cit., p. 201) as 

 having been bred from eggs laid by Teracolus topha, Wallgrn. 

 The example previously presented to the Hope Collection is 

 quite of the auxo form, though not extreme ; but the present 

 specimen, as noted by Mr. Marshall (loc. cit), shows a still
