YPONOMEUTID/E. OXYPATE DASYSTOMA. 235 



Genus CCCXXXIV.— Oxypate, Hiibner. 



Palpi minute, depending, hairy, the terminal joint exposed, acute ; maxilla; 

 wanting. Antennw short, stout, slightly pubescent within in the males, simple 

 in the females : head small, with a small tuft on the forehead : eyes large, 

 globose : thoi-ax subovate, not crested : wings slightly decumbent during 

 repose; anterior sublanceolate, narrowed at the base, costa straight; disc 

 smooth : posterior ample, ovate-triangular ; cilia all rather short ; in the 

 female small, much shorter than the body, lanceolate, pilose : body rather 

 slender, carinated down the back with a small tuft at the apex ; stouter and 

 slightly acute in the females : legs slender. 



From the foregoing and the preceding genera this may be known 

 by having the palpi very short and scarcely pilose, the wings glossy 

 and smooth, with two distinct dark spots on the disc, the nervures on 

 which are not elevated : the female has very short wings, the ends of 

 which appear pilose : the only known species is brumal. 



Sp. 1. gelatella. Alis anticis fusco-cinereis, lined albidd punctisque duobus nigris 

 remotis. (Exp. Alar. $, 7 — 9 lin.) 



Ph. Py. gelatella. Linne.—N. G. gelatella. Steph. Catal. ii. 202. No. 7260. 



Anterior wings in the male ashy-brown, with a faint whitish vitta, or streak, 

 in the middle, terminated at each end by a conspicuous round black dot ; 

 posterior immaculate ; female with mere rudiments of wings, rather paler 

 than in the male, with the two black dots somewhat distinct. 



Rare : it has occurred in Epping Forest, near Walthamstow ; also 

 in Hampshire, but apparently local : on 27th December 1822 I saw 

 a great quantity flying in All Saints' Church-yard, Hertford, of 

 which I secured a pair, but since that period I have not seen the 

 insect alive. 



Genus CCCXXXV. — Dasystoma, Curtis. 



Palpi longer than the head, enveloped in dense elongate hairs, which almost 

 conceal them : maxillce wanting. Antennw moderate, ciliated in the males ; 

 in the female the basal joint large and swollen: head transverse, pilose: 

 eyes moderate, globose : thorax broad, hairy : wings decumbent during 

 repose; anterior sublanceolate, the costa curved, hinder margin rounded; 

 the disc with two long basal nervures and one transverse one towards the 

 apex elevated ; posterior moderate, ovate-triangular ; cUia all shortish, but 

 rough : the female with the anterior wings about half the length of the 

 body, narrow, rough; body rather long and stout, especially in the females, 

 , with a slight tult at the apex : legs rather stout.
