A new Species of Agrotis. 



Read the following description, by Mr. Henry Doubleday, of a new species of 

 Agrotis taken in Britain : — 



"Agrotis Ashworthii. Alis anticis cinereis, strigis tribus denticulatis atris, 

 macula quadratd nigra inter stigmata, posticis fuscis. (Exp. alar. 1 unc. 

 5—8 tin.) 



"Anterior wings cinereous, powdered with black atoms, with three denticulated 

 strigae arising from black spots on the costa ; one near the base, a second before, and 

 a third beyond the middle of the wing. Between the stigmata (which are very in- 

 distinct) is a quadrate black spot, and another between the anterior stigma and the 

 second striga ; a fuscous cloud crosses the centre of the wing as in Tasnioeainpa 

 populeti, T. instabilis, &c. ; cilia fuscous. Posterior wings fuscous in both sexes, 

 with the cilia paler; head whitish; thorax cinereous; abdomen pale fuscous; an- 

 tenna? fuscous, white towards the base. 



"This pretty species, which appears to be quite unknown upon the Continent, was 

 discovered" at Llangollen, North Wales, by Mr. Ash worth, in the summer of 1853, 

 and the specimen forwarded to me for inspection. Last summer many specimens 

 were taken by Messrs. Cooke, Gregson, &c, as noticed in Mr. Stainton's 'Ento- 

 mologist's Annual,' where the insect is figured under the name of Spaelotis Vallesiaca. 

 The figure, however, is by no means good, the anterior wings being much too broad. 



" I forwarded a specimen of the male and a drawing of the female to my friend, 

 M. Guenee, and he says that he believes it to be quite new ; I have therefore named 

 it after its discoverer: it is closely allied to A. lucernea, A. decora, &c." 



Part iv. vol. iii. New Series, of the ' Transactions,' published in April, was on the 

 table. 



The President announced that Mons. Alex. Yersin, of Morges, Canton de Vaud, 

 Suisse, is engaged on a Monograph of the Gryllidae and Locustidae, and solicits the 

 loan of British species. 



June 4, 1855. — John Curtis, Esq., President, in the chair.
