tinctly lunulated as in Neolycaena lunulata, tengstroemi, or 
sinensis, and in one or two specimens one almost sees the 
cusps running basally for a small distance, especially in the 
first costal spots of the hindwing. One variation is specially 
to he noted, two or three specimens have dark inner margins 
to the lunules, as is usual in C. ruhi hut which I had not seen 
in my captured specimen of C. avis. In one or two specimens 
there may he seen a trace of the silvery eyebrows, so character¬ 
istic of C. ruhi. 
On emergence the dehiscence of the pupa differs in one respect 
from that of C. ruhi. In both species the prothoracic plates 
sometimes separate from the rest of the pupa case, sometimes 
they remain attached to the anterior border of the mesothorax; 
the difference between the two species is, that it is rather the 
rule for them to separate in C. avis, rather the exception in 
C. ruhi. 
The few empty pupa cases also exhibited show this, so far 
as a few can do so; they also display the brown colouring of 
the wing cases in C. ruhi, and their nearly black in C. avis, a 
difference rather more marked when they are alive. 
South African Lycaenidae. —Mr. Hamilton Druce drew 
the attention of Fellows to his recently published book on 
“ Some South-African Lycaenidae'' a copy of which he 
exhibited. 
Canadian Coleoptera. —Mr. G. C. Champion called atten¬ 
tion to a paper of interest to British Coleopterists, published 
in Canada, entitled “ Some Guests at the Banquet of Blossom,” 
by T. J. A. Morris, read at the Annual Meeting of the En¬ 
tomological Society of Ontario, November 4th, 1909, and 
published in the “Canadian Entomologist,” December 1909, 
pp. 409-418. 
Papers. 
Separation of British Species of Hydroecia. —Mr. J. W. 
Tutt delivered a short address on “ The species of the nictitans 
group of Hydroecia." He discussed the several forms of 
Hydroecia occurring in Britain, and illustrated the superficial 
differences where discoverable, and the marked difference in 
the anal appendages of the several species, Hydroecia nictitans,
