On experiments made at the Boiadu Boulogne in 1866-1868 on sericiculture, 
see Pinion, Bull. Soc. Imp. d’Acclim. 2® s^rie, vi. pp. 20-30. 
^ A translation of a paper hy P. L. Simnionds on Sericiculture in India is re- 
printed in the same Journal, pp. 633-643, 694-606, from the Revue des Cours 
Scientifiques. 
Tomiigs-OAiCEDO states (Bull. Soc. Imp. d’Acclim. 2® s^rie, vi. pp. 467- 
469) that the larvae of Bomhyx spmdice and allied species cut the thread of 
their cocoons before they are completed — and that if the larvm are hilled 24 
or 27 hours after they begin to spin, the cocoons can be wound off in a con- 
tinuous thread without breaking. 
Guerin-Meneville publishes (Rev. et Mag. de Zool. 1869) a series of 
articles entitled “ Sericiculture Compar^e ” of more special than general in- 
terest. The epidemic is decreasing, he reviews its progress, and disputes 
Pasteur’s conclusions, attributing it to disease in the mulberi’y ; he records 
Baron de Bretton’s success in rearing B. yama-mai, remarks on the failure of 
Japanese eggs of this species, quotes a letter of Bretton’s saying that only 
the leaves of well-grown and acorn-bearing oaks should be given to the 
worms after their third moult, states that eggs of this species hatch sooner 
if they have travelled ; he records the experience of various sericiculturists in 
rearing B. won, states that it has been reared successfully on the Madura^ 
recommends that silkworms should be reared with great care and in small 
quantities to obtain healthy eggs, and generally reviews the progress of 
sericiculture during tlio current year I860. 
Various remarks and papers on sericiculture, which it is unnecessary to 
refer to in detail, will be found scattered through the ^ Journal d’Agiiculture 
Pratique ’ for 1869, under the headings of Chronique agricole;” “Compte 
rendu des stances du congres de Lyon,” “ Revue etrangere,” Sericiculture,” 
“ La Campagne sericole,” " Bulletin de I’lndustrie sericole,” &c. On serici- 
culture in Italy see Personnat, Journ. d’Agric. pratique, 1869, i. pp. 49-52 ; 
in Corsica, with reference to Pasteur’s remedy for the silkworm-disease, see 
Maillet, .Comptes rendus, Ixix. pp. 361-363 ; in England, &c., with special 
reference to rearing S. mori for the sake of the eggs, see Wallace, Entom. 
Annual, 1870, pp. 146-166. 
Aitacm cynthia. On rearing this insect in France in 1868 and on its para- 
sites see Girard, Ann. Soc. Entom. Fr. S»5ances, pp. 97-99. 
De I’Orza states (L^pid. Japon. p. 43) that it is almost naturalized in France, 
where plantations of Ailanthus exist. 
„ On rearing A. cynthia in Ireland, see Kirby, Journ. Roy. Dubl. Soc. vol. v. 
pp. 366-370. 
Anthertxa yama-mai. Dr. Wallace has published a report on the success 
obtained by himself and various correspondents in rearing this insect in Great 
Britain in 1867, 1868 : 65 of his correspondents out of 180 were successful 
in obtaining cocoons. He classifies the varying success of his correspondents, 
and, in summing up, enumerates the various forms of disease that affect this 
silkworm, discusses the question of contagion or infection, describes the mode 
of emergence from the cocoon, the habits of the perfect insect, &c., adds 
some directions for the treatment of the worms, and quotes a letter from a 
correspondent in Japan respecting the habits and treatment of the worm in 
that country. 
Dr. Wallace also publishes notes on the cultivation of this silkworm in 
Scotland and Ireland. Ent. M. Mag. v. pp. 252, 253.
