General Notes. 
Presas (Anuario del Liceo de Mantanzas, i. pp. 239-246) publishes a 
general account of* the structure, habits, &c. of the Lepidoptera, especially 
with reference to those of Cuba. 
PniTTwiTZ (Stett. ent. Zeit. 1867, p. 276), in describing a new Callimorpha^ 
makes some remarks on the affinities of the different members of the group 
Nocturni. 
Prittwitz also remarks (/. c. pp. 276-277) upon the fondness displayed by 
certain moths (e. g. Acmtia Solaris and Arctia vilUca) for the vicinity of 
human habitations. 
Frauenfeld (Verb, zool.-bot. Ges. in Wien, xvii. pp. 431-432 & 446- 
440) notices the species of Lepidoptera collected on board the * Novara’ during 
her voyage. The number of species recorded is 42. The most numerously 
represented groups are the Geometridse, Pyralidse, and Tineida?; and the 
author suggests that the predominance of these is due to their possessing less 
power of flight than the Noctuidse and Sphingidoe, the latter having less 
occasion to rest upon the ship, and being able to escape from it more easily, 
on account of their greater power of wing. A large flight of Papilio hectm' 
visited the ^Novara’ at some distance from Ceylon. 
A. S. Packard publishes (Proc. Post. Soc. N. H. xi. pp. 32-63) a list of 
the Lepidoptera collected in Labrador, with remarks on many of the known 
species and descriptions of numerous new ones. He remarks that the Le- 
pidopterous fauna of the coast is of an Arctic character, agreeing 'closely 
with that of Greenland, whilst in the interior of the country, which is 
warmer, the fauna acquires a large intermixture of boreal or Canadian forms. 
A catalogue of Eversmann’s collection of Lepidoptera lately presented to 
the Entomological Society of Russia by the Princess Helena Paulowna is 
published by the Society with the Horse Soc. Ent. Ross. tom. v. 
J. C. SiEVERS, jun., publishes (Horse Soc. Ent. Ross. iv. pp. 49-77) a cata- 
logue of the Lepidoptera of the Government of St. Petersburg aivanged upon 
the model of the general catalogue of Staudinger and Wocke. The total 
number of species cited by him is 1274, namely, of Rhopalocera 97^ of 
Sphinges, Bombyces, and Noctuse 373, of Geometrse 216, and of Microlepido- 
ptera 686. 
SiEVERS adds 30 newly captured species (Bombyces and Noctuse 4, Geo-
