and easily rubbed as T. pulverulenta , the very act of impaling 
often rendering it totally unfit for inspection. 
Tinea ferruginella , Hiibn. 
Expanse 5^-6^ lines. With the fore wings of a brownish 
tinge mottled with paler scales, the basal portion being slightly 
darker. The inner margin is of a pale yellowish white; and 
there is likewise a rather conspicuous spot on the disk of the 
same pale hue; the fringe is concolorous with the inner 
margin, but interrupted with blackish scales. Hind wings 
cinereous, the fringe being of the same tint. Thorax con¬ 
colorous with the anterior wings, except the centre, which is 
of a pale yellowish white. 
This little Tinea is not at all abundant in the island. The 
few specimens I met with do not appear in any way to differ 
from those in my British collection, except that the fore wings 
are less glossy and without the purplish tinge of the latter, 
though this may, indeed, be partly owing to my St.-Helena 
examples not being in very good condition. 
Tinea pellionella^ Linn. 
Expanse 5-6i lines. With the fore wings of a dull pale 
brownish hue, and having near to the middle of the disk two 
rather longitudinally placed dark brown spots, which are 
generally more or less distinct; there is also a third, more con¬ 
spicuous and likewise more rounded, dark brown, postmedian 
spot. On close inspection it will be observed that there are 
numerous cinereous scales throughout the wing, intermingled 
with the pale brownish ones ; in fact the number of each is 
perhaps well nigh equal ; the cilia are also cinereous. Hind 
wings of a pale (rather brownish) cinereous throughout. 
As I only met with two examples of this little Tinea , I 
conclude that it must be a somewhat scarce species in the 
island, and perhaps even only recently introduced. Especially 
might this, I think, be the case, as it was not observed by 
Mr. Melliss. So far as I can judge from merely two speci¬ 
mens, it does not appear to differ much from the European 
type, though possibly, on the whole, it may be a trifle darker 
than the ones with which I have compared it in my British 
collection. 
Tinea binotatella. 
Tinea binotatella , Walk, in Melliss’s St. Ilel. 191 (1875). 
Expanse 7-9 lines. With the fore wings of a dull and 
opaque dark cloudy brown, more or less besprinkled witli 
blackish scales. Some specimens, however, are darker, and
