BoMBYCIDiE. 
ScuDDER (Harris Correspondence) publishes Harris’s descriptions of the 
larvse of Clisiocampa sylvatica, Gastropacha amei'icana, p. 292, G, velleda, 
Attacm Inna (pi. 4. fig. 14), p. 293, A. polyphenm^ (pi. 4. fig. 17), A. cecropiay 
p. 294, Saturnia io, p. 295, Ceratocampa regalis, p. 297, Dryocampa senatoria 
(pi. 2. fig. '9, pi. 4. fig. 12), D. stigma (pi. 2. fig. 12), D. pellucida, p. 298. 
lie also (1. c. pp. 130-134) publishes notes by Harris and Doubleday on 
various Bomhyces, mostly undetermined, and their larvse, and copies Harris’s 
remarks on the classification of the group (pp. 135-140, 144, 152-166). 
He also {1. c. pp. 3G4-36G) reprints various notes on American Bomhycidm 
from the first edition of Harris’s “Insects injurious to Vegetation,” which 
had been inadvertently omitted in the third edition. 
The editors of Ent. M. Mag. (v. p. 230) quote a paragraph from an Aus- 
tralian paper containing an account of a railway-train being stopped by a 
swarm of hairy caterpillars, which they suppose to have been those of one of 
the Bomhyces. The engine could not grip the rails in consequence of the 
quantities which were crushed beneath the wheels. 
Lasiocampa quercus. A gynandromorphous specimen of this insect (left 
side cf, right side $) has boon bred by John Wilson. The abdomen was 
thicker than in the male, and not tufted. Proc. Ent. Soc. Lond. 1868, p. 38. 
G. R. Porritt states that the larva of this species will eat heather. Ent. 
M. Mag. vi. p. 117. 
An Alpine variety of this species is described, and its habits, in all its 
stages, recorded by .7. Fallou, Ann. Soc. Entom. Fr. 1869, pp. 61, 52. 
On varieties obtained by breeding, see M. Kershaw, Entomologist, iv. 
p. 351. 
Milliere (Ann. Soc. Linn. Lyon, xvii.) describes and figures varieties of 
Bombyx rnhi (p. 13, pi. 94. f. 7), and of Lasiocampa potatm'ia (p. 13, pi. 94. 
f. 8), bred by Lederer at Vienna. 
E. Holdsworth states (Proc. Ent. Soc. Lond. 1869, pp. 21, 22) that he 
has bred (Eona punctata, Lasiocampa remota, and Leheda hehes ? of Walker 
from the same larvae, at Shanghai. 
E. II. Todd records his having had a brood of larvae of Eriogaster lanestris 
in the summer of 1866, about 100 of which went to pupa. In 1867 the first 
moth appeared on Feb. 2nd, in 1868 on Feb. 20th, and in 1869 on April Gth, 
and some still remain in pupa. Ent. M. Mag. vi. p. 16. 
Clisiocampa castrensis. Life-history published by E. Newman, Entomo- 
logist, iv. p. 189. 
C. Miller and A. H. Jones publish notes on rearing this insect. Ent. 
M. Mag. vi. p. 114. 
C. americana, Harr., is noticed and figured by Packard, Guide to Study of 
Insects, p. 301, fig. 232. 
Sin'iciculturc. Girard reports the failure of the public experiments near 
Paris in 1869, tried with various species of silkworms. Ann. Soc. Ent. Fr. 
1869, pp. 489-492. He also (/. c. Stances, pp. 74, 76) publishes notes on 
double cocoons of various silkworms. These are generally, but not always, 
of different sexes. Suida has discovered that the power of absorbing humi- 
dity exists in the fibre of silk, and not in its gloss. Cosmos, 3e s^r. v. 
pp. 46, 47.
