together about an hour, after which S. ocellatus started laying, and in 
five days laid 56 eges. These eges are different in colour and shape 
from those laid by S. popwi, bemg a light pale green tinged with 
pinkish and more elongated. On June 14th some of the ova were slightly 
depressed. (3) On May 29th I bred a male Smerinthus ocellatus ; it 
began to fly about (as if in search for a mate) so I placed a female S. 
tiliae (bred the same afternoon) with it and both flew about the cage 
furiously, but the S. ocellatus darted at once on the S. tiliae and they were 
paired for half an hour when S. tiliae began struggling and they parted. 
I left them in the cage for five days, but still the @ S. tiliae laid no 
egos, I then killed the S. ocellatus, and later, on the same evening, 
the @ S. tiliae laid one egg. From June 8rd till June 14th eight 
egos were laid, all on the underside of lime leaves. I hope these will 
hatch, especially as | have never heard of these two species pairing 
before. { will report later as to the results.—C. P. Pickerr, The

Hasits oF CERTAIN HREBrAS.—We haye already described (Proc. Sth. 
Lond. Hint. Soc., 1898, pp. 64-5) the great difference that exists in the 
habits of the sexes of Hrebia nerine. This would appear to be pretty 
general amone many Hrebiid species. On August 3rd, 1899, a walk 
up the road from Simplon to the first refuge showed a number of 
males of Hrebia mnestra settling on the bare road, and with them 
swarms of Hrebia goante, I. pitho and FE. tyndarus. Not a single 
female F’. mnestra came to the road that we could discover, and the 
females of the three commoner species named, also insisted on keeping 
to the flowers of the slopes and roadsides, and rarely followed the 
habits of the other sex. The males will often sit three or four (or 
more) in a little heap, heads together, reminding one much of the 
eregarious habits of those of £’. nerine on the rocks of the Mendelstrasse. 
Dr. Chapman observed a pairing between the sexes of /. yoante. The 
male was seen to walk up to the female two or three times, without 
appearing to make much progress, when suddenly and without any 
apparent further courtship the insects suddenly paired. If 1. qoante 
be disturbed when paired, the male always appears most anxious to 
get away, and hurries off as rapidly as possible, carrying the female.—

Morus ATTRACTED BY, AND DROWNED IN, THE DRAININGS FROM A 
MANURE HEAP.—On August 2nd, 1899, Dr. Chapman and myself took 
a walk to the pastures stretching to the right hand, about a mile or 
two from the village cf Simplon, goime towards the summit of the 
pass. These slopes form a remarkably good collecting ground, and on 
this particular day we saw Colias phicomone and C.h yale haunting the 
same ground. ‘The abundance of Syrichthus alveus here is slonestt 
incredible, the @s distinctly sprinkled with yellow, and the males 
flying early i in search of the newly emerged 9° s, which hide among 
the grass, whilst Polyommatus corydonis nearly as abundant. Brenthis 
pales is common, this species extending quite down to the village. The 
common Hrebias are melampus, tyndarus, pitho and goante, whilst FP. 
euryale is comparatively rare. I may here note that of three females 
of this latter species captured, not one was like the others, and one of them, 
although evidently a female, presentsnone of the characters of the under- 
side that distinguish the latter sex, but is exactly similar in this
