180 HAUSTEI.I.ATA. — LEPTDOPTEKA. 



Found in June against fir-trees near Birch wood, not very- 

 common ; but in July 1827 it was in plenty in a fir plantation on 

 Ockham Heath, near Ripley. 



Sp. 6. comitana. Alis anticis fuscescentibus, nitidis, strigis duahus geminatis 

 punctisque variis subargeuteis. (Exp. Alar. 4 — 6 lin.) 



To. comitana. Wien. Verz. — Ps. comitana. Steph. Catal. ii. 176. No, 6934. 



Anterior wings brownish, with a reddish tinge, with a geminated silvery streak 

 near the base, and a second, slightly angulated before the middle, and 

 between this and the hinder margin numerous irregular spots, most of them 

 double, one of which on the anal angle forms an oval ring ; cilia silvery- 

 brown ; posterior wings fuscous, with paler cilia. 



This species is also very subject to vary in the tint of its anterior wings. 



Abundant in June amongst fir trees at Birch wood: I am not 

 aware of any other locality. 



Genus CCCIX. — Rhyacionia, Hiibner. 



Palpi short, slender, approximating in form of a beak, ascending, densely 

 clothed with short scales, leaving the terminal joint, which is acute, exposed : 

 maxiUas very short. AntennoE rather long and slender, more robust and 

 very pubescent in the males : head small, with a loose tuft of scales on the 

 front : eyes large, globose : thorax globose, not crested : wings entire ; 

 anterior rather elongate-triangular, with the hinder margin obliquely 

 truncate, disc black, with raised darker scales, and a very oblique toothed 

 white band, sometimes broken into spots, rather before the middle ; posterior 

 wings small, ovate, faintly waved on the margin : cilia short : body short, 

 rather slender, with a very small tuft at the apex. 



In this genus the anterior wings are short, and have the costa 

 straight and the hinder margin obliquely truncate, thereby forming 

 a triangle ; the surface is black, with darker elevated scales, and a 

 very oblique snowy-white fascia, which is occasionally more or less 

 broken up, and dentate outwardly, a character possessed by no other 

 indigenous species. 



Sp. 1. Hastiana. Alis anticis nigro-fuscis, fasciA medid antrorsiim obliquanivea, 

 punctis elevatis nigris. (Exp. Alar. 6 — 8 lin.) 



Ph. To. Hastiana. Lime.— Or. Hastiana. Sfeph. Catal. ii. 182. No. 7022. 



Anterior wings brown-black, with a broad oblique snowy-white fascia in the 

 middle, extending towards the anal angle, and furnished on the outer edge 

 with an obtuse prominence; the hinder portion of the wings with a few 

 raised black scales : posterior wings and cilia brown.
