the Lepidoptera of St. Helena. 441 
uniform in tint throughout, except the inner margin, which 
is slightly paler. 
This species, so far as I could ascertain, appears to be ex¬ 
ceedingly rare; and I only met with three examples of it—one 
of which I captured at Plantation, the other two being found 
in a very remote and inaccessible part of the island, namely 
amongst some gumwood trees between Peak Dale and 
Lufkins. 
Genus 44. Platyptilus, Hiibn. 
Platyptilus suhnotatus. 
Platyptilus subnotatus, Walk., in Melliss’s St. Hel. 193 (1875). 
During our sojourn in St. Helena we did not meet with this 
scarce little moth. 
Mr. Walker’s description was taken from a unique example 
which was found in the island by Mr. Melliss at the Hermi¬ 
tage. 
Genus 45. Oxyptilus, Zell. 
Oxyptilus rutilansj Walk. 
The present Oxyptilus seems to have been first described 
by Mr. Walker (who regarded it as a Pteropliorus) in 1863, 
from examples which had been received from Natal; and as 
it is especially throughout the cultivated districts that it occurs 
in St. Helena, there seems every reason to conclude that it 
may have been imported originally into the island, perhaps 
amongst the quantity of plants which must from time to 
time have been introduced from South Africa. Although 
principally abounding at intermediate altitudes, such as 
Plantation, Oakbank, Cleugh’s Plain, and elsewhere, it 
ascends likewise, though more sparingly, to the lower parts 
of the great central ridge, being exceedingly common at West 
Lodge. But around Plantation it may be said often to 
swarm; and I have frequently observed several examples at 
the same time on a single flower at rest, with the fore wings 
spread horizontally so as to conceal the under ones (after the 
manner of the genus), and, moreover, so sluggish that one 
might pick them easily from the flowers and grass on which 
they happened to be settled.
