GENERAL NOTES. 375 
Keferstein replies to some of Maassen’s criticisms on his paper, S. E. Z. 
1870, pp. 353,364. 
Speyer (S. E. Z. 1870, pp. 202-224) compares the structure 
and metamorphoses of the Lepidoptera and Trichoptera in full 
detail^ in order to discover what relation exists between the 
orders. He considers that the two groups are very nearly allied, 
the Trichoptera having been first developed, but that no very 
obvious links now exist between them. Acentropus he considers 
to be a true Lcpidopteron, hut a very old form. The most highly 
developed forms of the Lepidoptera are the butterflies ; then fol- 
low tlic Sphinges, Noctu(n, and Geometrm, while the Bomhyces 
form a transition to the Microlepidoptera. 
Hagen suggests that an examination of the genital segments 
would he of the greatest use in the determination of species in 
the most difficult groups of Lepidoptera, such as Argynnis, Hes- 
peria, the Noctuidee, Acentropus, &c. S. E. Z. 1870, p. 316, 
note. 
J. W. Douglas quotes from Hagen’s paper, and adds some remarks of his 
own. Ent. M. M. vii. pp. 43, 44. 
Zeller (S. E. Z. 1870, pp. 81-89) publishes a critical analysis 
of Snellen^s work on Dutch Macrolepidoptera. He argues 
that misprints and slips of the pen in the spelling of scientific 
names ought to be corrected, and that our scientific nomenclature 
ought to commence with the last edition of Linnoeus^s * Systema 
Naturae.^ He entirely disapproves of the names there used being 
supplanted by those employed by Linnaeus in earlier works, or 
by obsolete names employed by Clerck, Pod a, Scopoli, &c. 
Boisdu val protests against any of Hiibner’s generic names being retained, 
whether characterized by subsequent authors or not, leaving it to be inferred 
that his own manuscript names are preferable. Pet. Nouv. E. no. 19. 
T. .1. Bold publishes notes on a few British Lepidoptera. Tr. North. 
Durh. iii. pp. 170-172, 
F. Brauer has published the usual report on the literature of Lepidoptera 
in 18G9. Arch. f. Nat. 1870, ii. pp. 101-188. The part of the report re- 
lating to general entomology also contains much relating to Lepidoptera. 
The concluding portion of the report on Lepidoptera is not yet to hand. 
W. M. Crowfoot (Tr. Norw. Soc. 1809-70, pp. 29-30) remarks on the 
breeding, variation, and localities of British Lepidoptera, the difference in 
the Indian and European butterfly faunae, and the resemblance in the Sphinx 
fauna3. He classifies the Lepidoptera of Norfolk by their localities, as fol- 
lows : — marsh, heath, coast, and foreign species, and those frequenting cul- 
tivated ground. 
J. W. Dunning remarks on a small collection of insects sent from Kiii- 
sembo in Congo, by H. Ansell. Lists of the fifty-nine species of Rhopalocera 
and the twenty-three species of Heterocera contained in the collection are 
appended by Messrs. Butler and Moore. Tr. E. Soc. 1870, pp. 522-528.
