‘“‘ (2) Three specimens of Pinacopteryx pigea, Boisd. 
“These three males are the specimens referred to by Mr. 
Marshall (oc. cit., pp. 206-208) as d of the first series, and 
g, & 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 ]ess conspicuous in the present group 
of males than in the females just referred to. 
(3) A male specimen of Zeracolus anne, 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 pup 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 (/oc. 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 Zeracolus 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 (doc. cit.), shows a still 
closer approach to the fullest @uxo condition, which is known 
to be characteristic of the wet or summer season. The two 
specimens now referred to are of great value as having afforded 
the actual synepigonic proof of the specific identity of the two 
phases 7’. awxo and 7’. topha. This identity had been suspected 
so long ago as 1877 by Mansel Weale, who placed some of his 
specimens of these forms in the Hope Collection. But, as the 
writer has elsewhere stated, Mr. Marshall’s experiments, the 
results of which are now at Oxford, remove the subject of the 
specific identity of these two forms from the region of probable. 
conjecture to that of actual proof.”
