(my 
Forman, one of the Assistant Secretaries of the Post Office, 
to the effect that the Postal Union had decided to make a 
rule not to admit natural history specimens by sample post, 
which was intended for the transmission of bona fide trade 
patterns or samples of merchandise, and consequently that 
the forwarding of such specimens at the sample rate would in 
future be irregular. 
Lord Walsingham stated that he had had a long corre- 
spondence with the Post Office authorities on the subject, and 
that the late Mr. Raikes, when Postmaster-General, promised 
him in 1891 that such specimens should, so far as the British 
Post Office was concerned, be transmitted at the sample rates ; 
and a letter to the same effect, from the late Sir Arthur 
Blackwood, when Secretary to the Post Office, was published 
in the Proceedings of the Society for 1891. 
Mr. C. G. Barrett exhibited for Mr. A. J. Hodges a speci- 
men of Hydrilla palustris, from Wicken Fen ; also specimens 
of Caradrina ambigua, from the Isle of Wight. He remarked 
that of the latter one specimen had the hind margin of right 
forewing indented, and the wing broadened as though from 
an injury to the pupa. In this wing the margins of the large 
orbicular and reniform stigmata had become so joined that 
the dividing. lines had disappeared, and the stigmata were 
fused into one irregularly formed blotch. The left wing of the 
specimen is normal. The effect of the injury seems to have 
been as though the two stigmata had been in a semi-fluid 
condition and had run together. 
Mr. McLachlan exhibited, on behalf of Mr. G. F. Wilson, 
I'.R.8., of Weybridge, a ‘‘ grease band ” which had been tied 
round trees to prevent the females of Cheimatcbia brumata 
from ascending the trunks for the purposes of oviposition ; 
the band was thickly covered with the bodies of the females, 
together with a few males. 
Surgeon - Captain Manders exhibited a pair of Chelura 
bifasciata, from the Shan States, and called attention to the 
‘Cagssembling’”’ habits of the male, some hundreds of which 
were attracted by the numerous females which emerged from 
the cocoons at sunset. 
Mr. B. A. Bower exhibited a beautiful variety of Zygana
