CIIRVSOCOKYS. 217 



rich metallic brown, or very dark saflVon, with a silvery mark at the 

 base, extending a short distance along the inner margin, and then 

 turning np 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 ; Mi\ Dale met witli it 

 in Dorsetshire, Mr. AVeir in Sussex, and Mr. Allen Hill ncir 

 Bristol; it appears in June and July, in moist places among 

 alders.

 Head smooth, the forehead convex. Antennre 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. AVings 

 with long cilia, the anterior narrow, the costa almost retuse, convex 

 before the apex ; the posterior lanceolate. In the anterior wings the 

 diseoidal 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 contaius one species, which has a peculiar 

 jerking lliglit, as it were, ho])ping on the wing, lliibner has 

 figured a larva and pupa as of this species ; but tliough his figures 

 have been on several occasions copied, no subsequent writer has 

 verified his observations, and consc(|uently it is hardly safe to 

 conclude that the larva and pupa are really as singular as he has
