p. 264. 
HYALORISTA, gen. nov. 
Fore wings elongate, three times as long as wide; costa 
straight ; hind margin oblique. Hind wings lkewise some- 
what elongate. Palpi rostriform, long for the size of the 
species; forehead slightly protuberant; ocelli present; an- 
tennz simple, slightly pubescent in male; scaling fine and 
smooth. 
Type H. teniolalis (Rhodaria), Guen. D. & P. p. 172. 
A natural group of insects hitherto comprehended within 
the elastic limits of Botys ; of comparatively small size and 
delicate structure, with the usual markings almost wholly 
absent ; both wings showing a dark marginal suffusion ; the 
hind wings nearly transparent. 
Hyalorista imitans, sp. n. 
Fore wings yellow, suffused with darker towards the costa ; 
an oblique, broadish, purplish-grey band near the base, and 
another submarginal; the outer edge of the former and the 
inner edge of the latter rather irregular; an indistinct dark 
ocelloid spot at end of cell; traces of an exterior line appear 
on the costa and in the disk. Hind wings whitish yellow, 
yellow only along the inner margin, with an indistinct 
darker submarginal band and a distinct purplish-grey blotch 
on the inner margin. Head, thorax, and abdomen rather 
deep yellow. Underside dull yellowish, with the markings 
faintly darker. 
Expanse of wings 14 millim. 
Three males from 8. Paolo. 
Resembles teniolalis, but smaller and much more indis- 
tinctly marked. 
ADELOIDES, gen. nov. 
Characterized by the enormous length of the antenne and 
the difference in the shape of the fore wings of the sexes. 
Male with fore wing very narrow; the apex produced; the 
hind margin very oblique. Female with fore wing broader,
