B. Hatschek gives anatomical details on the feggs of J3omhyx cliry- 
sorrhcBa^ adding observations, on the nervous system of insects, and its 
homologies with that of other Arthropoda. Jen. Z. Nat. xi. pp. 115-148, 
pis. vii.-ix. 
The extensible tubercles of the under surface of the first thoracic seg- 
ment in most butterfly larvae are probably analogous to the retractile 
osmatoria of swallow-tail larvae ; S. H. Scudder, Psyche, i. p. 168. 
On embryonic characters in larvae, with special reference to the Lepido- 
ptera ; A. Giard, OR. Ass. F. Sci. vi. pp. 660 & 661. 
On protective mimicry in caterpillars ; T. D. G. Carmichael, P. Phys. 
Soc. Edinb. iv. pp. 169-163. 
General observations on broods of Lepidoptera, colours of larvae, &c. ; 
the only important point noticed is that Weismann’s interpretation of the 
colouring of Sphinx larva is disputed. W. von Reichenau, Ent. Nachr. iv. 
pp. 241-243. 
Harrach, Nahruiigswechsel bei den Raupen in verschiedenen Zeitrau- 
men, Einfluss der Futterpflanze ; Ent. Nachr. iv. p. T86. 
The colours of British caterpillars are tabulated, with reference to 
their protective character, by J. Lubbock, Tr. E. Soc. 1878, pp. 239-258. 
Discussion on the colours of larvae, with reference to Sir J. Lubbock’s 
paper ; P. E. Soc. 1878, pp. iv.-vii. Cf. also H. H. Crewe, Ent. xi. p. 118. 
On the variation in colour and habits of the larvae of Catocala nupta 
and Biston hirtaria, as modified by surrounding circumstances ; H. M. 
Golding-Bird, Ent. xi. pp. 108-111. 
Notes on various larvae ; T. Goossens, Pet. Nouv. ii. pp. 210 & 211. 
It is said that cabbages may be protected from caterpillars by growing 
dill with them, and gooseberry bushes by growing broad beans near them ; 
Nature, xviii. p. 318. 
Mimicry in cocoons ; H. Dewitz, Arch. f. Nat. xliv. 1, p. 20, Kosmos, ii. 
pp. 84-88. 
The interior of a cocoon is always of the same temperature as the sur- 
rounding atmosphere ; it is therefore no protection against cold, but 
exhibits mimicry in many instances ; J. de Bellesme, Bull. So. Nord (2) i. 
p. 270. 
On the emergence of Lepidoptera from their cocoons ; Westwood & 
Weir, P. E. Soc. 1878, p. xxxix. 
W. Breitenbach describes the structure of the proboscis in various 
Lepidoptera, which gradually increases iti complexity from the simplest 
form to the highly developed organ which we find in Ophideres. The 
processes on the proboscis consist of modified hairs. It is mentioned, on 
the authority of R. Trimen and others, that Achcea chamceleon is very 
destructive to ripening peaches in South Africa, whereas JSgyholis vaiU 
lantina appears only to attack fallen fruit, rotting on the ground. Arch, 
mikr. Anat. xiv. pp. 308-317, pi. xxi., xv. pp. 8-29, pi. ii. 
H. Dewitz discusses the development of the wings of Lepidoptera ; Z. 
wiss. Zool. XXX. Suppl. pp. 90 & 91 (see also Hymenoptera). 
F. Muller publishes some highly important observations on the neura- 
tion of the wings of Lepidoptera in the early stages of the pupa. The 
neuration is much more complicated than in the fully developed insect.
