8 HAUSTELLATA. LEPIDOPTERA. 



brown spot ; near the hinder margin is a pale waved streak, and the hinder 

 margin itself is darkened : posterior wings paler, with a central band with 

 pale luteous edges ; and a pale waved streak near the hinder margin. 



Female similar, but paler. 



Caterpillar dusky-brown, with the back red; it feeds on the birch and beech 

 in September : the perfect insect appears in the beginning of June. 



Found in great abundance, about twenty years since, in Richmond 

 Park, but I believe it has scarcely occurred subsequently, at least in 

 that locality. " Epping." — Mr. H. Doubleday.

Wings brownish-yellow : anterior with two oblique brown strigae, bent 

 towards the costa ; the posterior one with a brown cloud attached towards 

 the outer margin ; between these streaks is a small black dot towards the 

 anterior edge of the wing: posterior wings with a single streak. 



I have hitherto seen but one example of this very distinct species, 

 which is in the collection of W. Swainson, Esq., who obtained it from 

 that of his late father : its locality is unknown. 



Genus CCXLV. — Cilix, Leach. 



Palpi short, remote, slender, distinct, acute : maxillcB very short. Antenntt 

 stout, short, curved, rather approximating at the base, in the males 

 slightly bipectinated, the pectinations very short, and scarcely decreasing 

 towards the apex ; in the females subserrate within : head small, densely 

 clothed with compact scales: eyes globose: thorax slender, pilose: tvings 

 entire, compressed during repose; anterior roimded on the hinder margin, 

 the apex not falcated ; the disc with an irregular cloud, marked with ele- 

 vated silvery nervures ; posterior narrow, roimded, entire: abdomen some- 

 what cylindric, stoutest in the females : legs short, rather stout ; interme- 

 diate and posterior tibiw with a pair of spurs at the apex, and the latter 

 with a second pair between the middle and the apex. Larva lacertiform, 

 attenuated in front, with the back gibbous, the apex also attenuated: pupa 

 inclosed in a cocoon. 



Cilix of Leach, a name published some years anteriorly to Euclea 

 of Iliibncr, as applied by him to this genus, differs from the other 

 genera of this family by several remarkable characters ; as the wings
