ON THE HABITS, &c, of CEETAIN BRITISH M1CRO-LEPIDOPTERA. 

 BY W. WARREN, M.A., F.E.S. 



I have lately come across some interesting accounts of hitherto 

 unknown or little-understood larva? of JKicro-Lepidoptera, which seem 

 almost, if not altogether, to have escaped observation in England. 



These are: 1st. — A paper, entitled, " Descriptions de Chenilles 

 de Micro-Lepidopteres inedites ou peu connues," published in the 

 Annales de la Societe Entomologique de France, 1885, ser. vi, vol. 5, 

 pp. 397 — 422, by M. Clement Lafaury, and read at the Meeting of 

 that Society, held November 11th, 1885. 2nd. — Three articles, headed 

 " Aus meinem entomologischen Tagebuche:" by Herr Ludwig Sor- 

 hagen, published in the Berliner Entoinologische Zeitschrift, vol. xxv, 

 1881, pp. 17—34, vol. xxvi, 1882, pp. 129—158, and vol. xxix, 1885, 

 pp. 81 — 108. 3rd. — A work by the same Herr Sorhagen, called, 

 " Die Kleinschmetterlinge der Mark Brandenburg," published in 1886, 

 at Berlin, by Friedlander und Sohn. 



There are so many new facts and scraps of information contained 

 therein, along with a few errors which call for correction, that I have 

 thought it worth while to go briefly through them, with a view to the 

 assistance and enlightenment of those workers in this branch who 

 have not access to the originals. 



On the present occasion, I propose only to treat of the species 

 mentioned in the " Annales " by M. Lafaury. The paper contains 

 accounts of the larvae of 24 species, 11 of which do not occur in 

 England. The British species alluded to are the following : — 



Crambus inquinatellus, Schiff. Epischnia Boisduvaliella, Grn., = Farrella 

 Curt. Tortrix dumetana, Tr. Penthina (Sideria) achatana, F. JExartema (Ec- 

 copsisj latifasciana, Haw. Grapholitha littorana, Const., = Acroclita consequana, 

 H.-S. Tinea fiavescentella, Haw. * Depressaria badiella, Hb. Aplota palpella, 

 Haw. Coleophora niveicostella, Z. C. albicosta, Haw. (erroneously called albi- 

 costella, Dup.). *Chaaliodus insecurellus, Stn. Butalis siccella, Z. 



The three species marked * have been independently described 

 in England : badiella, by the late Mr. Buckler, Ent. Mo. Mag., vol. 

 xxi, 1884, pp. 3 — 7 ; insecurellus, by myself, Ent. Mo. Mag., vol. xxiv, 

 1887, p. 144 ; and siccella, by Mr. Bankes, Ent. Mo. Mag., vol. xxiv, 

 1887, pp. 246, 247. 



Crambus inquinatellus, Schiff. 

 Larva sluggish, greyish-yellow ; head shining black ; thoracic plate shining, 

 concolorous with the body ; spots and spiracles very large and conspicuous, feeds 

 very slowly on Hypnum ; spins up early in May, but only changes to pupa in 

 August, and emerges a month later.
