(as hitherto universally known) of an unicolorous white, varied from dull white to 
_orange-brown and even brownish black, and the majority of them exhibited all the 
markings usually found on the anterior wings of the females; the ground colour of 
the females was in some cases dull orange-brown, in others dull dirty white. Thus 
each sex appeared in the garb of the other. The number of the typical form of the 
insect was a small fraction of the total number captured; and but for the occurrence 
of the few normal specimens, the variety would doubtless have been regarded as a 
completely distinct species. 
Mr. A. R. Wallace exhibited some Longicorn beetles collected by Mr. James 
Lamb at Penang and in the province of Wellesley. Mr. Lamb had collected Cole- 
optera in that locality during the last four years, and amongst bis captures were a 
couple of hundred species of Longicornia, of which upwards of seventy were laid before 
the Meeting, nearly the whole of them being new to Science; many were referrible to 
genera discovered by Mr. Wallace in Borneo and Singapore, whilst others were more 
nearly allied to the forms occurring in Siam. 
The Rev. Hamlet Clark (on behalf of the Rev. O. Pickard-Cambridge, who was 
present as a visitor) exhibited a collection of Lepidoptera (including Micro-Lepi- 
doptera), Hymenoptera and Orthoptera from the banks of the Nile. Mr. Cambridge 
remarked that insect-life was not abundant in Egypt; the specimens exhibited 
included every Micro-Lepidopteron which he saw. He also called attention to the 
seed-pod of a Cassia, from which had emerged a Lycena ; but the pod had not been 
opened, so as to show the pupa. 
The Secretary read the following extract from a letter addressed to him by 
Mr. Roland Trimen, dated Cape Town, November 12, 1864:— 
“T observe in the Report of Proceedings on March 7th, 1864, p. 10, that Professor 
Westwood described as a new species a butterfly from the Zambesi, under the title of 
Charaxes Argynnides. There can be no doubt whatever that this insect is Nymphalis 
Jablusa of my ‘Rhopalocera Afric Australis’ (Part I. p. 177), as I have carefully 
compared Professor Westwood’s description with my own and with specimens of 
N. Jahlusa, and have examined an example of this butterfly brought from the 
Zambesi by a member of the mission party. The resemblance which this Nymphalis, 
in coloration and marking, bears to the species of Argynnis is, as the Professor 
states, very remarkable, and is noticed in my Catalogue (p. 178). It is singular, how- 
ever, that no true Argynnis has been taken in South-Eastern Africa, the only Fritil- 
lary known to inhabit the region being Atella Phalanta, which has no silvery spots on 
the under surface of the wings; so that the silver-studded Jablusa can hardly be held 
to present one of those remarkable cases of mimicry which have been lately shown to 
be not uncommon amongst butterflies. The markings of the upper surface, however, 
correspond very nearly with those exhibited by Atella Phalanta.”’ 
Mr. Dunning mentioned that the Rev. J. Collins, of Shepley Parsonage, near 
Huddersfield, had recently captured in that neighbourhood a considerable number 
(fifty or sixty specimens) of Dasypolia Templi; they were found in quarries, amongst 
loose stones, in the ruins of old houses, or in heaps of stones by the road-side, &c., and 
were generally very snugly ensconced, resting on the under side of the stones. The 
time of capture was the end of November and beginning of December, which, how- 
ever, was too late in the season, for very few males were found, and those were 
generally dead. The specimens varied in colour, some having a yellowish tinge, 
others being brown or nearly black; and it was necessary to leave them for a long
