SCYTHROPYIA. 57 
whitish. Antenne dark fuscous. Anterior wings rather dark grey, 
with a slight violet tint, with very faint indications of longitudinal rows 
of fuscous atoms; before the middle of the whitish inner margin is a 
dark fuscous spot, which appears to be continued obliquely, nearly 
across the wing; a small whitish spot lies on the costa before the apex ; 
apex of the wing and cilia coppery-grey. Posterior wings rather pale 
grey, towards the base whitish, with pale greyish-fuscous cilia. 
An abundant species in hedges and gardens, appearing in April 
and May, and again in August. ‘The larva feeds on hawthorn,

Capilli hirsuti. Ocelli nulli. Haustellum brevissimum, nudum. Palpi 
labiales breves, filiformes, penduli. Alse anteriores elongatee, medio- 
criter ciliate. Ala posteriores oblongo-ovate, foveola hyalina nulla. 
Alw anteriores: vena apicalis simplex ante apicem exit, infra eam 
rami sew ; vena subdorsalis fureata, sed furcee ramus superior debilis ; 
posteriores : cellula costalis elongata, coarctata; vena mediana trifida. 
Head rough. Ocelli none. Tongue very short, naked. Labial 
palpi short, filiform, drooping. Anterior wings elongate, with moderate 
cilia. Posterior wings oblong-ovate, zoé with a hyaline patch at the 
base. In the anterior wings the simplex apical vein runs into the costa 
before the apex ; below it sie veins run to the hinder margin; the sub- 
dorsal vein is fureate, but the upper branch of the fork is rather obso- 
lete. In the posterior wings the costal cell is narrow and elongate ; 
the median vein is ¢rifid. 
This genus only contains one species, of which the larva is 
gregarious, thus approaching in habit towards the following 
genus.
