GENERA AND SPECIES. 191 



1. Gelatella, Lin. Faun. Suec. 1450. Hub. Tort. PI. 42, Fig. 



Both the above insects are included under the same head, 

 by Mr. Stephens. 



Gen. 1027.— Ederesa. Curt. 



Palpi slender and drooping, longer than the head, the crown of which 

 is clothed with a tuft of hairs : superior wings linear-lanceolate, the 

 costa arched, with a pale or white interior margin, interrupted by 

 a dark oblique fascia. 



8. Semitestacella. Curt. 



Testaceous, shining : palpi, crown of head, and antennte white ; the 

 latter beautifully spotted with black : superior wings, with a white 

 flame-shaped stripe on the inferior margin, and 2 pale spots on 

 the costa towards the apex : inferior wings gray, cilia fuscous : 

 tibiae and tarsi spotted above with black. (Length 2, breadth 

 7 lines.) 



The type of this genus is the Tin. pruniella, Linn. : the form 

 of the superior wings, and their pale inferior margin, will 

 distinguish this group from my Argyromiges, as well as from 

 Argyrosetia. Tin. semitestacella was taken in the New Forest 

 by Mr. Lyell ; and it is possible that my E. semipurpurella 

 may only be a dark variety of the same. 



Gen. 1039. — Chrysocorys. Curt. 

 Palpi slightly curved, slender, and attenuated, longer than the head, 

 composed of 3 joints, apparently of nearly equal length : antennae 

 rather short, and serrated with whorls of short scales : head and 

 thorax clothed with metallic scales lying close to the surface : 

 abdomen short and slender : wings narrow and lanceolate : 

 superior long, and slightly disposed to be falcated : cilia long : 

 spurs to hinder tibiae exceedingly long and slender. 



1. Angustipenella, Guide. Scisscella, Haw. Lep. Brit. 



580, 69. 



I think there is little doubt but this pretty and curious little 

 moth is the Tin. Festaliella, Hubner, PI. 67, 449 ; but I am 

 doubtful if it be his Tin. scissella, PI. 39, 270, the wings being 

 of a different shape. 



Order. — Homoptera. 



Fam. — Tettigonid^. Curt.
