Papilio machaon; varieties of Zygena jilipendule, including 
several of the yellow form; the series having been taken in Kent. 
Also varieties of Lycena bellargus, among which were a number 
of light female forms and two black males. Mr. Sabine stated 
that, with the exception of the latter, the whole number had been 
taken either in the spring or autumn of the present year, and he 
was of opinion that they were hybrids between bellargus and 
icarus, he having on one occasion, at the same locality, taken a 
male of the former im cop. with a female of the latter species. 
Mr. Weir remarked that the light varieties of the female were 
undoubtedly hybrids between the two species mentioned by 
Mr. Sabine, but the curious part of the matter was, that they 
should have been taken both in the spring and autumn. With 
regard to the black forms of the male, he had neither seen nor 
heard of anything of the kind before. Mr. W. West (Greenwich) 
exhibited two species of Coleoptera from Shirley Heath, viz., 
Balaninus rubidus and Hrirrhinus pictoralis. Mr. T. R. Billups, 
a species of Hydradephaga: Colmybetes fuscus, from which had 
emerged a lepidopteron, probably Hndrosis fenestrella, the empty 
pupa-case being partly visible, and remaining firmly attached to 
the body of the beetle. 
October 21st, 1886.—-The President in the chair. Mr. T. R. 
Billups exhibited the following species of Ichneumonide :— 
Trogus lutorws and its rare ally T'rogus alboguttatus, bred by 
Mr. R. Adkin from Cherocampa porcellus ; also a fine series of 
Apanteles jucundus, both sexes being represented, and the cluster 
of cocoons from which they emerged. Mr. Billups stated these 
little Microgasterides were bred from the larvee of Pieris brassice 
from Ireland, and which were handed to him by Mr. South. 
This was the first time the insect had been recorded as having 
been reared; and the Rev. T. A. Marshall, in describing this new 
species last year in his ‘Monograph of the British Braconide,’ 
had but one specimen to work from, a female taken by sweeping 
in Northamptonshire. Mr. Levett and Mr. Watson exhibited 
specimens of Acherontia atropos. Mr. Helps, Lastocampa 
quercifolia. Mr. West (Streatham), two yellow varieties of Bryo- 
phila perla from Margate. Mr. W. G. Sheldon, Plusia chryson, 
P. festuce and P. pulchrina. Mr. Ficklin, a long series of 
Pedisca sordidana. Mr. Jager, Sphina convolvuli taken at 
Starcross, Devon. Mr. Gibb and Mr. Tugwell both exhibited
