270 Chronicles of Science. | April, 
M. Ganine, of Karkow, has since, however, denied this statement, 
and describes the reproductive organs as two little sacs placed in 
the eleventh segment of the body, and in which the germs, or 
pseudo-ova, are developed. This account has been substantially 
confirmed by Dr. Leuckhart and M. Pagenstecher. 
Dr. Asa Fitch, in his ‘ Reports,’ &c., states that a new’enemy to 
the bee has appeared in the Nebraska territory, and so great has 
been the destruction caused by it, that no swarm had been thrown 
off during the season, or at least up to the time of the Report. The 
insect in question—Trypanea apivora—is a fly belonging to the 
family of Asilidze, some of which are known in Europe to attack 
bees, wasps, and even insects so formidable and apparently so well 
protected as the tiger-beetles (Cicindelz). 
A work by M. A. Edouard Pictet, entitled ‘Synopsis des Néu- 
ropteres d’Espagne,’ has just been published at Paris and Geneva. 
It is, we believe, the first production of one who has hereditary 
claims to our attention had he no others, which, however, is far 
from being the case. The plates—fourteen in number—by the 
well-known artist Nicolet, are printed in tinted ink suitable to each 
insect figured, and coloured by hand. Only in this way could the 
delicate gauze-like wings of these marvellously exquisite creatures 
be portrayed, and this has been done with a success that may 
be almost pronounced perfect. The Libellulide are retained among 
the Neuroptera.

At the December meeting, the Secretary exhibited a general 
collection of insects made by Lieut. Bevan at Moulmein, and in the 
valley of the Solween. It was mostly composed of Indian and not 
Malay types. Mr. F. Smith exhibited numerous specimens of a 
moth used for food by the natives of New South Wales, and named 
by them “ Bugong” (Agrotis spini, Guén.). It is found in large 
numbers in November and December, when their bodies are in a 
very oleaginous state. A beautiful series of engravings of the 
insects of the United States, together with their transformations, as 
far as they are known, made by Mr. Glover, of Washington, was 
exhibited by Mr. Moore. The Rev. Joseph Greene exhibited a 
series of Acidalia subsericeata and A. mancuniata, some of which 
appeared to throw a doubt on the claims of the latter to the specific 
distinction which it has been quite recently supposed to possess. 
Professor Westwood read descriptions of new species of Cantharoc- — 
nemis, including two new genera or sub-genera ? Mr, MacLachlan 
read a paper on varieties of Stervha sacraria, with notes on the 
variation of species in the Lepidoptera. Mr. Semper (of Altona) 
sent drawings and a description of a remarkably fine new species of 
Papilio from the Samoa Islands.
