Capilli deprcssi, frons ol)tu<a. AiiU'iuid^ alis rnulto longiores, articiilis 

 corapressis. Haustelluin mediocre, sfpiamatum. I'alpi maxillares 

 brevissiiui. Palpi labiales iiiediocres, adsccudentes, articulo secuudo 

 longiorc infra pilis appressis, apieem versus iiicrassato, tertio siilj- 

 erccto, teiiui, aciiiuiuato. Aire ollaiif/(r, iiiediooriter ciliat;e, antL-riunnii 

 casta convcwa, ap'ice acuLo. Alic anteriorcs : vensx) apicalis rami supra 

 et infra apiccm exeunt ; cellida secundaria iiulicata ; vcna^ median;e 

 ramus primus a sccundo loiujhmnc distat, secundus et tcrtius in fur- 

 cam coaliti. Ahii postcriores : cellula eostalis latimcidu ; vena api- 

 calis a secpiente separata ; vena mcdiana trilida. 

 Head smooth, in front obtuse. Aiilcnnrp mm-li loiiger tliaa the livings; 

 the joints compressed. Tongue of moderate length, sealed. jMaxillary 

 palpi very short. Labial palpi moderately long, ascending ; the longer 

 second joint with appressed scales iieneath, thickened towards the apex, 

 third joint nearly erect, slender, pointed. AVings oUoiig, with moderate 

 cilia; the cosla of the anterior n:iiigs convex; the apex acute. In the 

 anterior wings, the branches of the apical vein run out above and below 

 the apex ; the secondary cell is indicated ; the first branch of the me- 

 dian vein is very reriiote from the second ; the second and third arc 

 imited into a fork. In the posterior wings the costal cell is rather 

 broad; the apical vein is unconnected with the following; the median 

 vein is tritid. 



This genus contains only one British species (another is, I be- 

 lieve, known on the continent); it is frequently beaten from hedges 

 and bushes, when it may bo observed Hying sluggishly, or rather 

 falling to the ground ; for indeed it only appears to make use of 

 its wiugs to break its fall. Tlie larva is polyphagous, feeding 

 under a web on the underside of the leaves of the oak, beech, 

 pear, bramble, etc.

 fore the middle, and two fuscous spots on the disc, one in the middle, 

 the other beyond the middle, sometiuies united to a fuscous blotch on 

 the fold ; the base of the eosta, and a quadrate sjiot on the cosia be- 

 yond the middle, are pale yellow ; the hinder margin and apex of the 

 costa rosy-fuscous ; cilia pale yellow, at the anal angle i)alo rosy-grey. 

 Posterior wings whitish, with a slight rosy-fuscous tint, with paler cilia.
