Head and, face dark grey. Palpi grey ; the end of the tliii-d joint 

 ochreous. Antennae dark fuscous. Anterior wings dark fuscous, varied 

 with ochreous, with scattered white scales; near the costa before the a])cx 

 is a conspicuous whitish spot (or anterior wings with the basal half 

 entirely whitish or dirty-yellowish, beyond which is a broad fuscous 

 fascia, followed by tawny towards the costa, the white spot before the 

 apex occurring as in the dark variety) ; from the inner margin i)roject 

 three tufts of tawny or fuscous scales ; cilia dark fuscous, with a light 

 spot below' the apex. Posterior wings grey, with paler cilia. 



Appears in July and Angnst, and October, liyberiuitcd spe- 

 cimens occurring in spring; it frequents UmhelCifoys among 

 hedges. The larva feeds at the end of June and beginning of 

 September on various UmfjeUiferce ; 1 have found it o\\ Ant/i riscus 

 Si/lve&trls, Tonlis Anthriscus, Sison Amonmm, ILeradtuiii SjJton-

Genus VII. LAVERNA. 



Laverna p., Curt. B. E. fo. 735 (183'J). ElacMda p., Zell. ; Dup. 

 Capilli la^vcs, frons obtusa. Antenna3 abdominc longiores, sctaceaj, ar- 

 ticulo basali elongato, clavato, crassiuscuhc. Palpi labiales medio- 

 cres, recurvi, articulo seeundo apiccm versus laxe squamato, subcla- 

 vato, tertio breviore acuto. llaustcllum mediocre, parce sqiiamatum. 

 Ala3 longissime ciliatie, antcriorcs Inhcrnduto-squariiaUe, tuhercnlh 

 non melallicis, dorso non dcntato ; posteriores lineari-lanceolatte. 

 Head smooth ; the forehead obtuse. Antenn;c longer than the ab- 

 domen, setaceous, rather thick, with the basal joint elongate, clavate. 

 Labial palpi moderately long, recurved ; the second joint subchnate, 

 towards the apex loosely scaled ; the third joint shorter, acute. 'Ipngue 

 of moderate length, sparingly scaled. Wings with very long cilia, the 

 anterior with titfts of scales, tlio. tufts not nidalllc, the inner margin 

 without projecting tufts ; the posterior wings linear-lanceolate. 



The limits of this ami several of the following genera are by no 

 means satisfactorily settled. The present genus admits of being 

 readily divided into three grou])s. 



A. Anterior wings with a distinct pale costal spot; the furcate apical 

 vein runs into the costa before the apex ; below \ifive veins proceed 

 to the hinder margin ; the subdorsal vein furcate at each end, the 

 basal fork long, the apical fork shorter. This singular appearance 

 no doubt arises from the thickened apex of the svibmedian vein be-
