Ph. Ti. scquclla. Linnc.—Y\). sequcllus. Stcph. Catal. ii. 223. No. 7525.— 

 Anesyciua, Hiibner. 



Anterior wings white, or snowy, with a common, very much waved, deep 

 black streak at the base of the inner margin, and on the costa several black 

 cruciform and minute spots and dots of dissimilar form: cilia white, more 

 or less clouded, or intcriupted with black: posterior wings pale ashy- 

 brown : head, thorax, and palpi white : anteiuue faintly amudated with 

 dusky. 



A rare species: I have twice taken it in the lane leading to 

 Darcnth wood from the main road, opposite Sutton ; and in July 

 1827 I found it at Uiploy. It has been frequently taken in the 

 former locality, and also near Westcrham, &c. : it is, however, a rare 

 species. 



Genus CCCLXXIV. — Cerostoma, Latreille. 



I'ulj d ihyxr ; maxillary minute; labial rather long, slightly curved upwards, 

 clothed at the base witli a long projecting bunch of scales, extending con- 

 siderably beyond the palpi, the terminal joint of which is very long, slender, 

 sparingly clothed with minute scales, and exposed above, resembling a seta: 

 maxilla; shortish. Anfenntc slender, thickened at the base, simple in both 

 sexes, porrected forwards during the repose of the insect : head small, with 

 a short tuft in front: e'j/cj moderate: thorax not crested : wings elongate, 

 deflexed during repose ; anterior narrow, with the hinder margin rounded, 

 the disc generally dark, with a pale streak on the iinier margin; cilia 

 shortish: posterior brown, with long cilia: bodi/ rather long and slender, 

 with a small tuft at the apex in the males, obtuse in the females : legs 

 moderate. 



From the preceding genus the present one differs in having the 

 anterior wings narrower, more elongate in proportion, and rounded 

 behind, with the disc dark, bordered on the inner edge with a more 

 or less waved pale streak ; the cilia are shortish on the anterior wings 

 and very long on the posterior : the palpi rarely differ from those of 

 the foregoing insects ; but the antennae are somewhat more slender, 

 and arc directed forwards during the repose of the insect.
