all the veins of both fore and hind wings are blackened for a 
short distance from the margins, and there are traces of an 
additional black spot towards the middle of the hind 
wings. 
‘“‘In the spring females the dark tips of the fore-wings are 
smaller and greyish, and the black spots are also smaller. 
The fore-wings, however, are much more suffused with grey 
at the base than in the summer specimens; and usually all 
the veins of both fore and hind wings are strongly marked 
with grey, giving the insect a radiated appearance. This 
grey veining often almost takes the place of the dark tips of 
the fore-wings, and in one instance the dark tip is com- 
pletely broken up in this way. 
‘“The green veining of the under surface of the hind wings 
is much stronger in the spring insects than in the summer 
ones, and in the former the under surface of the fore-wings 
is also strongly marked with grey, especially in the females. 
It is noticeable that in the females of the summer brood the 
green veinings are weakest, while the males of the spring 
brood are more strongly marked than any others; thus the 
insects with the strongest marked upper surfaces have the 
weakest veinings on the under sides, and vice versa.” 
Mr. Montgomery also exhibited a uniformly xanthic speci- 
men of Epinephele tithonus, and a good variation of Abraxas 
grossulariata, in which the discoidal spot of the hind wings 
was extended into an additional well-defined band. 
Mr. McArthur exhibited a specimen of Arctia cata, having 
both fore and hind wing on one side perforated, and a per- 
fectly fringed indentation in the hind margin of the fore- 
wing. He stated that the larva had been several times 
disturbed while forming its cocoon, and finally turned to a 
pupa on the bottom of the cage. The holes were caused 
by a particle of sand piercing the wing-case of the pupa 
whilst in a soft condition. This was considered an im- 
portant observation, as throwing light on similar malforma- 
tions. It was considered that “the indentation of the fore- 
wing had no doubt been caused by a similar obstruction. 
Mr. T. D. A. Cockerell communicated the following note 
on a curious case of protective coloration : 
‘At Mesilla, N. M., on August 15th, 1897, I sat down to 
rest while on a collecting excursion, and my eye fell on a 
clump of the whitish-green Batleya multivadiata, with its 
splendid orange composite flowers. In the middle of the 
clump wasa Vanessid pupa, while resting on one of the stems, 
about to cast its skin, was a Sphingid larva. These objects
