 No. 6123, 



Thorax fuscous, anteriorly pale ; abdomen cinereous: anterior wings deep fuscous- 

 ash, with the ordinary strigoe nearly obliterated, a pale ochraceous- white patch 

 in the costa towards the middle, bordered towards the inner margin with a 

 deep arcuated black spot ; the anterior stigma obsolete ; or rather confused in 

 the pale costal patch ; the posterior griseous, dusky at the base, and forming 

 the termination of the central black spot ; at the base of the wing is an irregular 

 black patch or streak, and towards the apex on the costa another placed some- 

 what obliquely, and from which a slightly imdulated pallid striga arises, the 

 space between which and the fringe is darker than the rest of the wing; fringe 

 dusky: posterior wings pale luteous- white in the males, with the hinder 

 margin rather dusky ; and in the females cinerascent, with the base palest. 



This species varies a little in size, colour, and intensity of markings. 



Caterpillar varied with cinereous and brown, with a pale lateral line and trans- 

 verse lineola on the sides : it feeds on the Chickweed (Alsine media), Marsh 

 Willow herb (Ephilohium palustrej, and Spinach ; changes in May to a brown 

 pupa, and the imago appears towards the end of June and beginning of July. 



Not very rare ; found in various parts of the country : I have 

 taken it at Daren th and Coombe woods, and in the lanes near Ripley 

 and Hertford; it also occurs in Devonshire, the New Forest, in 

 Norfolk, Suffolk, &c. " Bottisham," — Rev. L. Jenyns. " Epping."

Head and thorax reddish- white, the latter with a transverse black streak anteriorly: 

 anterior wings reddish-brown, with a reddish- white streak at the base towards 

 the costa, and the ordinary striga? nearly obliterated ; at the base is a flexuous 

 black line, which extends nearly to the posterior stigma, terminating in a black 

 spot ; the anterior stigma is round and pale cinereous, the posterior reniform 

 and dusky in the middle : the fringe is yellowish-red : posterior wings whitish. 



Caterpillar yellowish-green, with the Lead brown, a dusky-green dorsal Une, and 

 two whitish lateral lines. 



One specimen only of this beautiful insect has, I believe, hitherto 

 been captured in England; the locality of which is unknown to me: 

 it was obtained by Dr. Leach about fifteen years ago, and deposited 

 by him in the collection of the British Museum.
