I conclude that it must be the same species which Mr. Walker 
recorded from the island; and the following is his descrip¬ 
tion :— u Steel-colour, silvery beneath fore wings, with a broad 
silver-coloured band beyond the middle.” He adds that the 
state of the specimen recorded will not allow a more minute 
description. 
Lithocolletis aurifascia is one of the rarest of the St.- 
Helena Tineidaj. Indeed we only met with it sparingly in 
one locality, which was at Thompson’s Wood, where we found 
it occasionally concealed under the loose stones of a wall 
encircling probably the oldest gumwood trees in the island, 
or still more rarely flying over the foliage of the trees them¬ 
selves, the leaves of the latter being abundantly mined by the 
larvm.

This is one of the very few of the native moths, which have 
as yet been discovered, that we did not meet with — indeed 
the only already described member of the Tineidas from the 
island that we did not succeed in obtaining. Although I 
possess no evidence to point to such a conclusion, still I can¬ 
not help thinking that the present species may be found in 
those regions which are characterized by the u scrubwood ” 
(Aster ylutinosus, Roxb.), one of the aboriginal arborescent 
Composite which we had no opportunity of investigating, 
and which (although once so abundant that large tracts of a 
comparatively low altitude towards the coast were literally 
covered with it) is becoming year by year more scarce. 
Nevertheless I only offer this as a probable conjecture, and 
partly to account for our not having detected any trace of 
it amongst the other Composite which we were always so 
constantly searching.

Expanse 9-9^ lines. With the fore wings not cleft or 
divided, and of a pale greyish cinereous, the costa and inner 
margin being rather paler, which gives the central area 
(which is large, elongate, and wedge-shaped) a somewhat 
darker appearance. Hind wings greyish cinereous, being
