244 HAUSTELLATA. — LEPIDOPTERA. 



to which is a large unequally suflPused rosy blotch, between the first and second 

 strigaBj and behind the posterior one are two other very obscure trihneated 

 fascisBj sometimes entirely wanting ; at the apex is an oblique fuscous striga, 

 and somewhat parallel with the hinder margin is a pale undulated band : cilia 

 slightly clouded with cinereous : posterior wings palei-, with an obsolete striga 

 in the middle. 

 The two central fasciae are frequently united, and differ as to their relative 

 distances from each other. 



Not uncommon in several places within the metropolitan district, 

 especially at Coombe and Darenth Woods, and in Epping-forest ; 

 also in Devonshire, the New Forest, Norfolk, &c= " Epping." —

Anterior wings of a bright ashy-grey, with two somewhat interrupted fuscous 

 brown fasciae in the middle, two rather obscure ones on each side thereof, and 

 a striga near the base. 



Differs in being of a larger size ; the colours brighter, and the strigae forming 

 five fasciae, as it were, on the anterior wings. 



Supposed to have been taken at Coombe-wood. 



Genus CCVIII. — Scoria, Duponchel. 



Palpi rather long, porrected obliquely, approximating at the apex, clothed at the 

 base with long scales, and at the apex with short compact ones, the terminal 

 joint conspicuous, acute ; triarticulate, the basal joint long, robust, second 

 shorter, slender, terminal elongate-ovate : maxillce very long. Antennae stout, 

 simple in both sexes, pubescent in the males : head small, squamous ; fore- 

 head depressed : thorax slender, squamous : wings entire, with strong some- 

 what dilated nervures, immaculate ; posterior margins of all considerably 

 rounded : abdomen long linear, with a laminated tuft in the males ; stouter, 

 carinated on the back, and acute in the females. 



Duponchel justly rejects the name Idsea, — previously used for 

 a genus of exotic Butterflies, — and proposes the above name in 

 lieu, which I have adopted, though somewhat contrary to recent
