28 HAUSTELLATA. — LEPIDOPETRA. 



Sp. 1: ad vena. Alis anticis cinereo-glaucis obsolete strigosis, strigd posticd 



nigro-maculatd. (Exp. alar. 1 unc. 10 lin. — 2 unc.) 

 No. advena. Wien. V. — Po. advena. Steph. Catal. part ii. p. 89. No. 6262. 



Head and thorax reddish-ash, the latter with a dusky transverse streak in front: 

 anterior wings ashy-brown, with a slight silvery gloss, and three very obsolete 

 pale strigae, bordered with a darker hue, the first abbreviated, and consider- 

 ably waved, at the base, the second rather obUquely placed before the an- 

 terior stigma, the third behind the posterior one; and towards the hinder 

 margin is a more conspicuous pale waved one, edged on its anterior margin 

 with angulated fulvescent spots; on the posterior margin itself is a very 

 slender undulated black striga, composed of sublunate streaks: anterior 

 stigma pale, posterior larger, less distinct, with its outer angle whitish: 

 adjoining the second striga is sometimes a fuscous hook ; and the costa of 

 the wing is frequently spotted with whitish : posterior wings plain fuscous, 

 with an obscure marginal streak. 



Caterpillar feeds on the Leontodon taraxacum and Lactuca sativa : the imago 

 appears at the end of June, and frequents gardens. 



Not very common : taken occasionally at Coombe-wood, and in 

 other places within the metropolitan district: also in Norfolk, 

 Suffolk, and Devonshire. " Epping." — Mr. H. Douhleday. 



Sp. 2. nitens. Alis brunneo argenteoque variis, strigd posticd ex punctis angu- 



latis conjluentibus. (Exp. alar. 1 unc. 10 lin.) 

 No. nitens. Haworth. — Po. nitens. Steph. Catal. part ii. p. 89. No. 6263. 



Of this insect Mr. Haworth says, " I have seen but one specimen of the male, 

 which is closely allied to the former, but smaller, with the antennae setaceous, 

 naked, and not pectinated, and hairy, with the elaviform (or third) stigma 

 larger : the anterior wings browner, and more silvery behind, the reniform 

 stigma half edged with pure white towards the apex ; in other respects similar 

 to the last, but the posterior stigma without, whiter." 



This insect I should consider to be a mere variety of the fore- 

 going, differing in being rather smaller, and of a brighter hue, 

 were it not from the remarkable discrepancy in the structure of the 

 antennae : it has been taken in Norfolk, and near London. 



Sp. 3. bimaculosa. Alis anticis albido cinereoque nebulosis strigd posticd den- 

 ticulatd nigrd, stigmatibus magnis subocellaribus. (Exp. alar. 1 unc. 10 lin. 

 — 2 unc. 2 lin.)

Head and thorax cinereous or hoary, the latter with black transverse and longi- 

 tudinal streaks, and sKghtly crested : anterior wings clouded with whitish and 

 cinereous, with indistinct black waved strigse, and shghtly tinged with ful- 

 vescent; towards the hinder margin is a distinct waved and dentated black
