Body concolorons with the posterior wings. 
This elegant little Tinea , the black-and-white fore wings 
of which give it so conspicuous an appearance, is decidedly 
common in the higher altitudes of St. Helena, where I used 
principally to meet with it, resting on the lichen on the more 
or less perpendicular faces of the rocks, along the u Cabbage- 
tree Road,” below Aetrnon and Diana’s Peak. Nevertheless, 
although much less abundantly, it occurs occasionally as low 
as Plantation (some 1800 feet above the sea), where I have 
not unfrequently obtained it. During the early part of our 
visit to the island it seemed to be extremely rare ; but as the 
summer approached (about the end of December) it became 
very plentiful in the loftier portions of the great central ridge, 
even its brightly ornamented black-and-white surface render¬ 
ing it, however, by no means easy to detect (that is, in a state 
of repose) on the many-coloured lichen to which it is specially 
fond of adhering. The chrysalis of Tinea bicolor is of a very 
pale yellowish white, enveloped in a narrow and somewhat 
parallel-sided cocoon, which is a good deal flattened, so as to 
cause either edge to be sharply angular. The cocoon is almost 
white, being very little concealed or obscured by earthy 
particles. 
Tineapulveripennis, E. Woll. 
Expanse 3^-4| lines. With the fore wings narrow and 
about equally speckled with scales of a dark brown and an 
oclireous white (the latter having a slightly golden tinge). In 
general appearance, however, the darker portions seem to take 
the form of ill-defined and somewhat mottled or fragmentary 
transverse fascirn (about four in number); but the whole wing 
is so completely irrorated with lighter or darker scales, that it 
becomes difficult to define for certain the exact pattern that 
they respectively assume. The fringe is of a pale straw- 
colour, with a few darker scales intermingled. Hind wings 
silvery grey, but with the fringe rather paler. 
This pretty little species, remarkable for the narrowness of 
its speckled and somewhat ochreous-tinted fore wings, is, I 
should say, perhaps the most abundant of all the Tineidm 
which are found at a lofty elevation. Like its congeners, it is 
accustomed to rest during the daytime (exposed to full view) 
upon the moss and lichen which more or less clothe the rocks ; 
and it is not uncommon also on the trunks of trees. I do not 
remember, however, to have met with it at a much lower 
altitude than Plantation ; but on the high central ridge it 
absolutely swarms.
