In 1911 the 3 & of wmbratus began to appear, and at present 
the yellow and black ants are in about equal numbers, and 
live together in complete amity. 
Mr. DonisTHORPE commented on the interest of Mr. Crawley’s 
experience, remarking that while it had formerly been supposed 
that parthenogenetically laid ova produced only g g, Mr. 
Crawley had shown, and proved by dissection, that 9 9 were 
capable of parthenogenetically producing § 9. 
The Prestpent observed that parthenogenesis was not 
unusual in sawflies, and mentioned that in one species, Croesus 
varus, Vill., which bad been founded on a ¢ specimen, the 
original specimen was the only ¢ ever recorded, though the 
2 wasa well-known insect, and had been reared through several 
generations in captivity, no ¢ ever making its appearance. 
Dr. M. Burr remarked that the common “ stick insect,” 
Bacillus rossi, is largely parthenogenetic, and has been bred 
parthenogenetically for more than twelve consecutive genera- 
tions. Mr. C. O. Warernouse and others joined in the 
discussion. 
Meanic Lirnosia.—Mr. E. A. Cockayne exhibited a 
melanic specimen of Lithosia deplana, g, taken in Surrey last 
July. 
SiciniAn Ruopatocera.—Mr. J. Prarr Barrer exhibited 
some species of Sicilian butterflies taken this year, in contrast 
with corresponding British species, which he described as 
cases of “ painting the lily.” The species contrasted were 
Buchloé cardamines and EL. damone, Gonepteryx rhamni and 
G. cleopatra, Hipparchia semele and var. algirica. Small 
southern forms were also exhibited of Z. cardamines and 
Leptosia sinapis. 
AxpinE Lycarntps.—Dr. Cuapman exhibited living larvae 
of Albulina pheretes, and a living imago of Latiorina orbitulus, 
and read the following notes :— 
“In my. paper on Latiorina orbitulus, I suggested the 
probability that <Albulina (Lycaena) pheretes had a larva 
without a honey gland, and that on this ground it was possibly 
related to L. orbitulus (Trans. 1911, p. 153). I have, during 
the past summer, succeeded in testing the truth of this 
hypothesis, by obtaining the hitherto unknown of larva of
