Head dark tawny. Face and palpi white. Antennae fuscous. Ante¬ 
rior wings bright saffron-yellow, with a narrow shining white basal

cilia whitish. Posterior wings grey, with paler cilia. 
LITHOCOLLETIS CAVELLA, Zeller. On the 11th 
of January, 1853, I bred a specimen from birch leaves col¬ 
lected at West Wickham ; and not knowing to which species 
it should be referred I put it on one side for future investi¬ 
gation. Subsequently showing the specimen to Mr. Wil¬ 
kinson be recognised it as an insect he was in the habit of 
taking on the Addington Road fence, and Mr. Douglas took 
m any specimens there last spring. The species is rather 
conspicuous from its large size, and the first dorsal streak is 
less obliquely placed than usual, and frequently uniting with 
the short first costal streak forms an angulated fascia.
