222 HAUSTELLATA. I.EPIDOPTERA. 



Genus CCCXXV.— Acompsia, Hvbner. 



Palpi very long, slender, divaricating, recurved, densely clothed with short 

 scales compactly placed, apical joint very long and completely exposed, 

 slender, subulated : maxilloe rather long and scaly. Antennas rather long 

 and slender, the apical joint distinct, all simple : head small, globose, clothed 

 with imbricated scales on the forehead: eyes ?,mB\\: thorax not crested: 

 wings entire; anterior acutely truncate on the hinder margin, the disc 

 totally destitute of markings; posterior shorter and narrower, slightly 

 waved on the hinder margin towards the tip, which is rather obtuse : cilia 

 moderate. 



The extreme simplicity of the insects of this genus, the anterior 

 wings being totally destitute of markings, and being of an uniform 

 colour throughout, exclusively of their form, the hinder margin being 

 obhquely and acutely truncate, at once characterizes them, in addition 

 to which their long slender recurved palpi, of which the terminal 

 joint is very long and acute, their small glossy head, clothed with 

 depressed imbricated scales, &c. may be pointed out. 



A. Wings dark-coloured, totally immaculate : — Acompsia, H'iibner. 

 6p. 1. unitella. Alis anticis lucidis fusco-fulvis immaculatis, posticis atris, 



capite paljnsquejlavis. (Exp. Alar. 4 — 7 lin.) 

 Ti. unitella. Hubner.—is. G. unitella. Steph. Catal. ii. 198. A^o. 7233. 

 Anterior wings tawny-brown, shining, immaculate ; cilia the same; posterior 



black or blackish-brown ; cilia dusky : head and palpi ochreous-yellow and 



glossy. 

 Extremely variable in size, and slightly so in colour. 

 The caterpillar feeds on the apple and pear. 



Not very common ; taken by me in some plenty at the Hermitage 

 from June to August, and occasionally so late as October : it appears, 

 however, to be local. I have obtained it from other parts of the 

 country. 



Sp. 2. cinerella. AUs anticis fusco-cinereis, subnitidis, immaculatis, posticis paulo 

 satHraiioribus ciliis Jlavescentibus. (Exp. Alar. 8 — 9§ lin.) 



Ti. cinerella. Hiibner.—i>l. G. cinerella. Steph. Catal. ii. 198. No. 7232. 



Anterior wings pale ashy-brown, slightly shining, immaculate ; cilia rather 

 paler : posterior wings some'what darker, with the cilia slightly flavescent : 

 head and palpi rather glossy ash-brown. 



The only locality I know for this plain and pretty species is
