20 Mr. J. W. Douglas on the 



Sp. 58. Atriplicella. 



*Lita. Atriplicella, F. v. R. pi. 78, p. 223. 



G. Atriplicella, Z. 



Expansion of wings, 7 lines. 



Head and thorax griseous brown ; antennae dark brown ; palpi 

 second joint griseous, terminal joint brown, with a light ring in 

 the middle. Anterior wings griseous brown, with four black dots 

 faintly encircled with red, of which two are before the middle, 

 one obliquely above the other, the other two are beyond the 

 middle, side by side. Beyond these is a faint curved fascia, and 

 then some scattered black specks. Abdomen grey, on the under 

 side more yellow, with a black line on each side. Posterior wings 

 griseous, with yellowish grey ciliae. 



This species is figured and elaborately described by Fischer 

 (1. c), who says the larvae feed on Atriplex laciniata. 



Taken in Charlton Sand Pits, in July. 



Sp. 59. Obsoletella. 



Lita. obsoletella, F. v. R., pi. 79, p. 225 (non TL 



obsoletella, W. V.). 

 Ti. elongella, W. V.? 



Expansion of wings, 6 lines. 



Head, thorax and palpi yellowish grey, the terminal joint of 

 the latter darker ; antennae fuscous, annulated with grey. Ante- 

 rior wings yellowish grey, dusted with brown, and having four 

 black dots, of which two are just before the middle, one obliquely 

 above the other, the other two beyond the middle, close together, 

 and often joined, then forming a curved mark. Beyond these is 

 a faint fascia, or sometimes only the rudiments of one on the costa 

 and inferior margin. Ciliae somewhat luteous, sprinkled with 

 brown. Posterior wings silver-grey, with luteous grey ciliae. 

 Abdomen griseous, the basal joints bright luteous, especially when 

 the insect is alive. 



This species varies much in colour and in distinctness of mark- 

 ing. It much resembles, except in colour, the preceding G. Atri- 

 plicella, and is said by Fischer (1. c.) to feed, when in the larva 

 state, on the same plant, and all species of Chenopodium. I found 

 it common on the coast near Weymouth, and Mr. Bedell took it 

 near London.
