26 HAUSTELLATA. — LEPI DOl'TEllA. 



Genus XLl. — Lophopteryx* mihi. 



Palpi short, hairy, slightly ascending, biarticulate, the first joint elongate, 

 curved at the base, the terminal one short, ovate : maxillcs short, a little spiral. 

 Aiitennw short, filiform, simple and ciliated in the females, very slightly bipec- 

 tinated in the males, nearly vanishing towards the apex: head small; eyes 

 moderate : thorax crested : abdomen not elongate, rather stout ; apex of the 

 male with a trifid scaly tuft : wings compressed when at rest ; anterior sub- 

 triangular, the hinder margin rounded, and rather deeply denticulated ; the 

 interior with a single, elongate, squamous tooth towards the centre: legs 

 rather slender, downy ; the apex of the tibiw with two elongate spurs ; the 

 anterior internally simple. Larva slightly hairy, with one or two conical 

 protuberances on the anal segment alone ; hinder prolegs perfect : pupa foUi- 

 culated. 



In this genus I have included such insects of this family as have 

 the thorax crested, the anterior wings considerably denticulated on 

 the hinder margin, with one prominence on the inner, the antennae 

 short, and very slightly bipectinated in the males alone ; the ab- 

 domen scarcely elongate, with a trifid scaly tuft at the apex : the 

 larvae slightly hairy, with one or two conical eminences on the 

 anal segment alone. 



Sp. 1. camelina. Alis anticis ferrugineis fascia obscuriore denticuloque dor salt 

 rejlexo, posticis ochraceis, macula anali fused. (Exp. alar. $ 1 unc. 6 — 8 lin.

 No. 5973. 



Antennae ferruginous : thorax the same, with a yellowish patch behind : abdomen 

 ochraceous, with the sides and apex reddish : anterior wings ferruginous, with 

 a very delicate nearly obsolete undulated black streak at the base, another 

 before the middle, and a third rudimentary one towards the hinder margin on 

 the costa ; behind this are a few costal spots, and an obsolete pale striga : cilia 

 and dorsal denticolations tipped with blackish : posterior wings ochraceous, 

 with the nervures and margin rufescent, and a bluish-brown patch at the anal 

 angle. 



The intensity of the colours varies considerably: in some individuals there is a 

 deep brown flexuous streak from the dorsal denticulation to the costa, and the 

 black strigse are more distinctly shown : in others the ferruginous tinge pre- 

 dominates. 



Caterpillar delicate bluish-green, with paler longitudinal hues; the stigmata 

 purplish : the legs and two caudal protuberances bright crimson. It feeds on
