334! HAUSTEI.LATA. LEriDOPTERA. 



Extremely variable ; some specimens being very faintly marked with black, 

 and others having numerous longitudinal black streaks throughout the disc 

 of the anterior wings : the dark varieties are, however, rare, and interme- 

 diate shades occur. 



The caterpillar feeds on the Enonymus europeus : the imago appears in August 

 and September. 

 Very rare ; but taken sometimes rather plentifully in the lane 



at the bottom of Darenth wood, leading from Dartford. 



Sp. 2. nemorella. Alis anticis falcatis stramineis fusco striatis, punctoque medio 

 nigro, posticis aJbidis, apice fuscescentibus. (Exp. Alar. 10 — 11 lln.) 



Ph. Ti. nemorella. Linne. — Ph. nemorella. Steph. Catal. ii. 222. No. 7505. 



Anterior wings falcate, pale straw-colour, with a distinct longitudinal pale 

 fuscous stria from the base to the middle, having a darker or black dot in 

 the middle between it and the inner margin; towards the costa are some 

 fainter fuscescent streaks, and on the disc behind the middle some dusky 

 atoms : posterior wings whitish, with the tips fuscous ; cilia ochreous : 

 head and thorax white, the sides of the latter with a black line- 

 Also a scarce species : found in grassy places, on the borders of 



woods, &c. at Darenth and Birch, in August. 



Genus CCCLXXI. — Harpipteeyx, Hiibner. 



Palpi four ; maxillary minute ; labial rather long, slightly divergent, curved 

 upwards, the base furnished with very long scales, porrected forwards con- 

 siderably beyond the palpi, leaving the terminal joint, which is very slender 

 and acute, exposed as a seta in the middle : maxiUoc short. Antennce mode- 

 rately long, slender, rather thickened at the base in the males; simple in the 

 females : head clothed with long upright scales, forming a crest : eyes 

 small : tho7'ax not crested : wings deflexed during repose ; anterior narrow, 

 lanceolate, the apex falcate and slightly emarginate ; disc dusky or streaked 

 with paler colours, with the inner edge generally pale, sometimes with some 

 elevated scales; cilia short: posterior moderate, sublanceolate, with shortish 

 cilia: abdomen rather short, slender, with a tuft at the apex in the males, 

 acute in the females ; legs rather slender and longish. 

 This genus differs from the foregoing, not only by the smaller size 

 of the species, but in their anterior wings being of dissimilar outline 

 and colour : in these insects they are, in comparison with their length, 

 broader, the hinder margin is emarginate, and more or less falcate, 

 the disc generally dark, with a paler streak on the inner margin, the 

 cilia on the posterior wings are shorter than in those of the former 

 genus : the insects appear rather earlier in the summer, and do not 

 seem to affect damp and marshy places.
