TOttTRICID/E. — XANTHOSETIA. iQl 



The insects of this genus are remarkable for their lively yellow or 

 rusty tints, and are nearly destitute of markings, having only a spot 

 towards the middle of the inner margin of the anterior wings, and a 

 kind of circular streak towards the hinder margin, a portion of 

 which is made up by the coloured cilia ; the palpi are rather long ; 

 the anterior wings have a smooth elevation towards the hinder 

 margin, and the latter is slightly rounded: the insects occur about 

 July and August. 



Sp. 1. Zcegana. Alis anticisjlavis nitidulis, puncto medio castaneo, postice cas~ 

 taneo-rufis macula Jlavo, ciliisferitLgineis. (Exp. Alar. 9 — 11 I in.) 



Ph. To. Zoegana. Lrntu'. — Donovan, iii. pi. 106. /. 2. — Xa. Zogana. Steph. 

 Catal. ii. 192. No. 7148. 



Anterior wing-s bright slightly glossy yellow, with a varied chestnut spot in the 

 middle, towards the inner margin, the apex chestnut- or rusty-red, with a 

 large yellow spot, producing an irregular orbicular mark ; cilia of a rusty 

 golden-red: posterior wings fuscous. 



Not very common ; found in grassy places in August : I have 

 taken it at Darenth and Coombe woods, and near Hertford ; in the 

 latter places more frequently than elsewhere : it also occurs in the 

 New Forest and in Norfolk. 



Sp. 2. ferrugana. Alis ant ids ferrugincis, puncto medio fusco, postice fuscis 

 macula ferruginca. (Exp. Alar. 8 — 9 Ihi.) 



To. ferrugana. Haworth. — Xa. ferrugana. Steph. Catal. ii. 192. No. 7149. 



Anterior wings dull ferruginous, with a faint fuscous spot in the middle 

 towards the inner margin, the apex fuscous, with a large ferruginous spot ; 

 cilia dull fuscous : posterior wings deep fuscous. 



I strongly suspect that this insect is a mere variety of the foregoing, from 

 which it differs solely in colour. 



Rare : I have once taken a single specimen at Darenth in August; 

 and others have been found in Norfolk, and I believe it has occurred 



in the New Forest. 



Sp. 3. hamana. Alis anticis sulphureo-Jlavis nitidulis, punctulo obsoletissimo, 

 lituraque postica hamato ferrugincis. (Exp. Alar. 9 — Hi Hn.) 



Ph. To. hamana. Linne. — Xa. hamana. Steph. Catal. ii. 192. No. 7150. 



Anterior wings sulphur-yellow, with a very minute and obscure rusty dot in 

 the middle towards the hinder margin, and an oblique somewhat raised 

 streak of similar hue behind, extending from behind the middle of the disc, 

 wiicre it is slightly flexuous externally, to the anal angle ; the base and apex
