Peric yma — Ze thes — A canthol /pes. 273 



and darker grey, dusted with bluish-grey on the costa, hind margin, and suffused sub- 

 marginal band, and along a black line running obliquely from the extremity of the bluish 

 portion of the costa to the middle of the subterminal line, and then turning at right angles 

 towards the base as far as the inner line. The transverse lines are yellowish-grey, the inner line 

 curved, the elbowed line indistinct, and the subterminal line very distinct, yellow, bordered 

 outside with red, and projecting a sharp angle towards the base in the middle and above 

 the iimer margin. Hind-wings dull ochreous, with the nervures, a central lunule, an outer 

 continuous band, and an interrupted border not extending to the anal angle, brown. Expands 

 about I J inches. Inhabits South Spain, Algeria, and Syria in March and April, and again in 

 July and August, flying in dry woods by day. The larva is long, slender, and cylindrical ; 

 it is naked, and has only twelve legs, and is of a livid-grey colour, with a yellow head. 

 It feeds on Helianthcinnni Iialiiiiifoliiim, &c., in spring and autumn. 



GENUS VI.— PERICYMA (HERR.-SCHAFF.). 



Allied to Cerocala, but with shorter fore-wings, the hind margin obtusely angulated in 

 the middle, and the hind-wings with waved fringes. The antennae are ciliated in the male. 

 The only species, P. Albidcntaria (Freyer), resembles a Geoinetra in appearance ; the fore- 

 wings are yellowish-grey, with the half-line indicated on the costa, and all the transverse lines 

 black, bordered with whitish. The elbowed line is irregularly waved, but forms no distinct 

 teeth ; and the subterminal line is placed close to the fringes, from which it is only separated 

 by a whitish stripe, and it is continued on the hind-wings, which are paler than the fore- 

 wings and dusted with whitish ; the central area of the fore-wings, and the hind-wings, arc 

 indistinctly striated with brown. Expands about I inch. Inhabits Sarepta ; and a larger and 

 paler variety, Squalida (Led.), is found in Asia Minor. The moths are readily disturbed from 

 plants in the day-time. The larva is pale greenish-yellow, very long and slender, with fourteen 

 legs, but the first pair of prolegs are quite rudimentary. 



GENUS VII. — ZETHES (RAMB.). 



Wings narrow at the base, much widened towards the extremity, each with a projecting 

 angle in the middle ; antenna; slender, ciliated in the male ; palpi very long. The only 

 European species, Z. Lisiilaris (Ramb.), is dull ashy-grey, the transverse lines white, broadly 

 bordered with dark brown within, which shades gradually into the ground-colour ; the inner 

 line is curved, and the elbowed line forms two sharp teeth outside; in the marginal area 

 is a large triangular brown costal spot ; the markings of the fore-wings are continued on 

 the hind-wings, but less distinctly. Expands nearly i^ inches. It inhabits Corsica, South- 

 Eastern Europe, and Asia Minor, and is easily disturbed by day in dry weedy places 

 during the summer months. 



GENUS VIII. — ACANTHOLIPES (LED.). 



The only species, A. Regiilaris (Hiibn.), resembles Euclidia Triqiietra in size, shape, 

 and outline, but is more like an Ophinsa in colour and pattern. The wings are violet- 

 grey or brownish-grey, and the fringes are broad, unicolorous, and entire. The fore-wings 

 are marked with a black streak bordered with yellow on the disco-cellular nervule, the 

 central shade is blackish, very broad on the inner margin, and suffused on the costa, and there 

 is a yellowish transverse line, starting at two-thirds of the length of the costa, nearly
