CHRYSOCORYS. 24.7 
rich metallic brown, or very dark saffron, with a silvery mark at the 
base, extending a short distance along the inner margin, and then 
turning up towards the costa; beyond are three silvery spots on the 
fold and two on the disc; a silvery white spot is on the costa before 
the apex; at the anal angle are also some silvery scales; cilia fuscous. 
Posterior wings fuscous, with paler cilia. 
This beautiful species is a great rarity; Mr. Dale met with it 
in Dorsetshire, Mr. Weir in Sussex, and Mr. Allen Hill near 
Bristol; it appears in June and July, in moist places among 
alders. 
Genus XII. CHRYSOCORYS. 
Curysocorys, Curt. Ent. Mag. i. 191 (1838); Id. B, E.; Step. 
Schreckensteinia, Hib. V. Llachista p., Zell. 
Capilli leevigati, frons convexa. Antenne abdomine vix longiores, se- 
taceze, articulo basali devi, erassiusculee. Palpi labiales mediocres, 
subcurvi, tenues, acuti, articuli secundi apice pilis parum inerassato, 
tertio longitudine subeequali. Haustellum mediocre, nudum. Ale 
longe ciliate, anteriores anguste, costa subretusa, ante apicem con- 
vewa, posteriores lanceolate. Anteriores: cellula discoidalis postice 
dilatata, truncata; vena apicalis simplex, infra eam vene sex in mar- 
ginem posticum; subdorsalis simplex paulo post medium dorsi exit ; 
submediana non incrassata; posteriores: cellula costalis longissima, 
angustissima, venee in dorsum sex, quarum tres e cellule termino. 
Head smooth, the forehead convex. Antenne hardly longer than 
the abdomen, setaceous, rather thick, with the basal joint short. 
Tongue of moderate length, naked. Labial palpi moderately long, 
rather curved, slender, pointed, the apex of the second joint slightly 
thickened with hairs, the third joint nearly of equal length. Wings 
with long cilia, the anterior narrow, the costa almost retuse, convex 
before the apex; the posterior lanceolate. In the anterior wings the 
discoidal cell is dilated posteriorly and truncate; the apical vein is 
simple, below it are six veins to the hinder margin; the subdorsal is 
simple, terminating a little beyond the middle of the inner margin; the 
submedian is not thickened; in the posterior wings the costal cell is 
very long and extremely narrow, six veins run into the hinder margin, 
of which three from the end of the cell. 
This genus only contains one species, which has a peculiar 
jerking flight, as it were, hopping on the wing. Hiibner has 
figured a larva and pupa as of this species; but though his figures 
have been on several occasions copied, no subsequent writer has 
verified his observations, and consequently it is hardly safe to 
conclude that the larva and pupa are really as singular as he has
