In that excellent periodical, the * Revue et Magazin de ZoologieJ 

 conducted by M. Guerin-Meneville, I find the following memoirs and 

 references to Entomological works which have, more or less, recently 

 issued from the press : — "Essai sur les Coleopteres de la Polynesie ; " 

 — a continuation of a paper commenced in former parts of the 

 ' Revue,' containing descriptions of the Xylophaga, Longicorns, and 

 Chrysomelidee, &c. ; by M. Leon Fairmaire. " De l'appareil circu- 

 latoire et des organes de la Respiration dans les Arachnides ; " by 

 M. E. Blanchard : a paper of which there will be found a translation 

 in the ' Annals of Natural History ' for 1850, No. 31, vol. vi. (second 

 series) p. 67. " Sur la Circulation dans les Insectes ; " by M. Leon 

 Dufour (from a small 8vo work of 40 pages, published at Bordeaux, 

 in 1849). "Note sur le Calymus abdominalis (Callidium abdominalis 

 Oliv.);" by M. Mulsant. " Memoir sur l'etude Microscopique de la 

 cire appliquee a la recherche de cette substance chez les Animaux et 

 les Vegetaux;" by M. Dujardin. " GEufs de Lepidoptere eclos 

 quoique leur mere n'est pas ete fecondee ; " by M. Popoff. The com- 

 munication here referred to occurs in a note to M. Le Comte Manner- 

 heim's paper on " New Coleoptera of Siberia," published in the ' Bul- 

 letin de la Societe Imperiale des Naturalistes de Moscou," No. 1 

 for 1849, p. 223. M. Guerin states that several observers had 

 already called attention to the fact, that the eggs of certain Lepidop- 

 terous insects have been known to produce larvae, notwithstanding 

 that the eggs had not received the fecundating influence of the male ; 

 and that he had published in the.' Revue Zoologique' for 1847, pp. 

 266 — 268, some Notes, by M. Bourcier, and a Report, by M. Dumeril, 

 on this curious subject; whilst in the present notice would be found 

 a new instance of the fact, and this coming from a person worthy of 

 faith, and published by M. Le Comte Mannerheim. It is stated that 

 the eggs from a female of the Euprepia hololeuca, itself reared from a 

 larva, after having been laid from eight to ten days, gave birth to
