Bomhyx mori and Sericiculture. 
Gu#.rin-Mi5neville publishes (R. Z. 1870, pp. 46-48, 72-80, 214-224) 
his usual series of reports on Sericiculture. He records the continued success 
of Baron de Bretton, Madame Baumann, and M. Chazy in rearing Anthercca 
yama-mai) publishes a report from the French minister in Japan relative to 
the habits of the insect in that country, and the means adopted to rear it. 
(Of the eggs sent to France by this gentleman only 20 per cent, were fertile ; 
and most of these hatched before the oaks were in leaf.) Gubrin-M^neville 
also records an hermaphrodite specimen of Bomhyx mylitta, bred by M. Ilenzi, 
and thinks that the epidemic among B. mori is gradually decreasing. 
M. Renard has sent eggs of a very strong Chinese race to France ; the silk- 
worms were reared by dilFerent experimenters with varying success. Gubrin- 
Meneville attributes the epidemic to unwholesome food ; and, while not 
placing much confidence in M. Pasteur’s views, recommends that the matter 
should be further investigated. 
Delandre (R. Z. 1870, pp. 121-128) reviews the various publications on 
Sericiculture which have recently appeared in England, Holland, Austria, 
Prussia and Sweden. He publishes a letter from O. Zik, giving details of 
recent experiments in Austro-Hungary (pp. 153-168), and publishes (pp. 
189-192) an account of the progress of Sericiculture in Cochin China and 
Cambodia. 
A. Wallace has published (Ent. Ann. 1871, pp. 101-107) some notes on 
Sericiculture, chiefly with reference to the feasibility of rearing Bomhyx 
mori in England and the British colonies. For further remarks see Proc. 
E. Soc. 1870, pp. 10, 11. 
A. B. Farn has published an abstract, with useful additional notes, of a 
valuable official Report (No. 1) by Mr. Adams, secretary to H.M. Legation 
in China, on the “ Central Silk Districts of Japan.” Ent. v. pp. 87-91. 
On the Japanese silk-trade, see Proc. E. Soc. 1870, pp. 21, 22.
