56 HAUSTELLATA. — LEPIDOPTERA. 



stout, with elongate hairs on their outer edge. Caterpillar nakedj smooth, very 

 slender : pupa slightly folliculated. 



The retuse subemarginate anterior wings of this genus, combined 

 with the slenderness of the antennse, which are setose, slightly 

 crested thorax, and dissimilar palpi, sufficiently distinguish it from 

 the preceding and following, with which the continental naturalists 

 have associated it: the only species known are of obscure colours, 

 and the anterior wings are transversely marked with distinct, some- 

 what parallel, pale, nearly straight striga?.

Head and thorax uniform fuscous-ash ; anterior wings also fuscous-ash, with an 

 olivaceous tinge, with an abbreviated straight yellowish striga on the costa at 

 the base ; a second also straight placed rather obliquely, and midway between 

 the first and the anterior stigma, pointing from the body when the wings are 

 extended ; a third incurved one behind the stigmata, and between it and the 

 hinder margin, a fourth very obsolete undulated one: stigmata olivaceous, 

 with yellowish margins ; the third, which is placed between the ordinary an- 

 terior one and the inner margin, as in the Agrotes, arises from the second 

 striga; the hinder margin is rather darker than the rest, and has a deUcate 

 obscure pale line on its extreme edge ; cilia olivaceous : posterior wings fus- 

 cous, with pale cinereous cilia. 



It varies a little in colour, and in some examples there is a fuscous fascia across 

 the anterior wings, as in the following species. 



Caterpillar whitish-green, with pale stripes and small white spots, the head 

 black, with a white forehead : — it feeds on the poplar. 



Not common : found occasionally at Coombe and Darenth-woods, 

 and in Epping Forest, near Chigwell. " Epping." — Mr. H.

Head and thorax immaculate ashy-brown : anterior wings griseous-brown, with 

 an abbreviated slightly incurved pale striga at the base, a second, nearly 

 parallel with the former, between it and the anterior stigma, pointing towards 

 the body on the inner edge of the wings, when the latter are expanded, 

 and behind the posterior stigma a third also parallel with the others : each of 

 these strigae is margined on the outer edge with fuscous, and the space between 

 the third striga and the hinder margin is entirely of that colour, with an
