and dorsal margins, the latter very slightly. Abdomen slender, 

 shorter in the $ , tufted at the apex in both sexes. 



The only insect comprised in this genus was formerly asso- 

 ciated by J. F. Stephens, in his ( Illustrations/ with the Lozo- 

 t&nice, to which it bears considerable resemblance, both in form 

 and colour, and is still retained there by Herrich Schseffer. In 

 consequence of the folded costa being absent, and there being 

 only five apical nervures proceeding from the apex of the 

 discoidal cell on the anterior wings, the rounded apex, trun- 

 cated apical margin, besides other minor differences in struc- 

 ture, it can no longer remain in that position. M. Guenee has 

 erected it into a separate genus under the above name, but he 

 does not state upon what grounds. He has associated with it, in 

 his Catalogue, diversana and histrionana, two continental species, 

 which seem more properly to belong to the genera Tortrix and 

 Sericoris. 



1. Grotiana, Fab. Alis anticis ochraceis, subreticulatis ; fascia media 

 distincta obliqua, macula costali triangulari postica brunneis ; 

 posticis fuscis. J Exp. al. 5| 7 lin. 



Head and face ochreous. Eyes black. Palpi ochreous above and 

 at sides, usually paler between and beneath. Antenna above and 

 beneath fuscous ; basal joint clothed with ochreous scales. Thorax 

 in front, at sides, and behind, ochreous ; on vertex smooth, fuscous. 

 Patagia ochreous. Anterior wings shining, ochreous, with rich brown 

 markings. The base is streaked with reddish brown, with an ashy 

 irroration, followed by a plain, ochreous space, slightly clouded with 

 ashy ; the central fascia is brown and broad, but with undefined 

 edges, and somewhat angulated; it contracts a little towards the 

 middle, and dilates from thence to the anal angle ; the subapical patch, 

 more or less present, streaked with brown and rich ochreous, seldom 

 produced to, or confluent with, the central fascia ; the pale portions 

 of the wing streaked and reticulated with reddish brown ; the apidal 

 margin ochreous, sometimes brown. Apical scales dull drab ; cilia 

 paler, both becoming dilute at, and iron-grey beyond, the anal angle. 

 Posterior wings very pale grey, clothed with coarse fuscous scales, 

 darkest towards the margins. Marginal scales fuscous, with luteous 

 bases. Cilia grey at the anal angle, slightly straw-colour at the apex. 

 Abdomen shining, fuscous; the caudal tuft luteous. $ Exp. al.

A somewhat local species, and occurring sparingly, but does 

 not vary, excepting as to size. 



The imago appears in July among Hornbeam, Maple, and 

 Honeysuckle. Epping Forest, New Forest, Darenth Wood, 

 Martinhoe in Devonshire, Lcwisham, arid at Caesar's Camp, near
