medio, posticis striga unica, dilutioribus. (Exp. Alar. 1 unc.) 

 Py. emortualis. H'uhner. — Polypogon emortualis. Steph. Catal. ii. 158. 



No. 6766. 

 Brown or olive, with a yellowish tinge ; anterior wings with an incurved paler 



streak towards the middle, a short lunate one in the middle, and a waved 



one behind ; posterior wings with a single pale streak nearly on the hinder 



margin : cilia yellowish immaculate. 

 Caterpillar brownish-yellow, with an orange-brown dorsal line, and some 



black dots on the sides : it feeds on the ash, in the autumn : the imago 



appears towards the end of May. 



This appears to be a very rare species; a specimen is in the cabinet 

 of W. Swainson, Esq., and I possess one captured in Devonshire. 



Genus CCLI. — Colobochyla, Hiihner. 



Palpi short, porrected horizontally, not very slender, triarticulate, the terminal 

 joint scarcely visible till denuded, basal joint small, second elongate, 

 thickened towards the apex, terminal conic acute : maxillce rather short. 

 AntenncE short, faintly bipectinate in the males, slightly ciliated beneath in 

 the females : head rather small, with a short tuft of scales between the 

 anterior: c^/ej moderate ; thorax stoutish : wings entire, anterior subtrlan- 

 gular, with the hinder margin dilated, the disc with oblique coloured streaks : 

 posterior faintly emarginate on the hinder margin : abdomen moderate, 

 stoutest and acute in the females : legs slender, simple ; posterior tibioe with 

 two pair of spurs. Larva with fourteen legs, and with the pupa slender. 



The brevity and slenderness of the horizontally porrected palpi of the 

 insects of this genus, exclusively of the form, colouring and markings 

 of the wings, and general habit, at once point out characters of dissi- 

 milarity to the allied genera of this family : there is only one British 

 species. 



Sp. 1. Salicalis. Alis anticis cinereo-plumbeis, strigis tribvs subcequidistantibus 

 fulvescentihus tertid recurvanCtm ipso apice ducta, posticis albido-cincreis. 

 (Exp. Alar. 1 unc— 1 unc. 1 lin.) 



Ph. Salicalis. FaAr/cew*.— Madopa Salicalis. Steph. Catal. ii. 159. N'o. 6767. 



Anterior wings of an ashy lead colour, with three somewhat fulvous oblique 

 stripes, placed in general equidistant, the first before the middle, the second 

 in the middle, the third arising at the extreme tip of the costa and slightly 

 recurved ; on the hinder margin is an interrupted brownish line, and a few 

 black dots : cilia ashy : posterior wings whitish ash, with a short paler 

 streak towards the hinder margin, near the anal angle : cilia paler.
