the Lepidoptera of St. Helena. 
cealed or folded; the labial palpi are divergent, slightly 
curved, and scarcely attenuated towards the apex ; antennse 
about the same length as the anterior wings, having a distinct 
longish basal joint, and alike in both sexes. The fore wings 
are of a pale fawn hue up to about the middle, the remaining 
portion being of a deep velvety black, but divided from the 
former by a conspicuous transverse white line ; and there are 
also a few white specks or scales towards the apex, almost 
forming a second, broader (though, at the same time, broken- 
up and fragmentary) white line. The chief characteristic, 
however, of this moth, is the singularly attenuated and up¬ 
wardly recurved apex of the fore wings, which is turned back 
like a ciliated black-and-white hook. Hind wings narrow 
and of a blackish smoke-colour. Thorax fulvous; body 
somewhat paler. 
This extremely curious little Elachista (so remarkable for 
the apically recurved fore wings) is exceedingly local, and 
appears to be a true native of St. Helena. I found it toler¬ 
ably plentiful (although within a very circumscribed area) on 
Actason and the high ridge which connects that mountain 
with Diana’s Peak, particularly on the loftiest points; and, 
singularly enough, it does not seem to descend lower than a 
few dozen feet at the utmost. I could not detect it in any of 
its previous stages; nor was the imago particularly attached 
(so far as I could tell) to any particular plants ; for I usually 
captured it flying indiscriminately over the fuchsias, cabbage 
trees, and ferns through which we were compelled to scramble 
(as best we could) along the precipitous sides and acclivities by 
which alone the summit of Actteon can be reached. Although 
free from strictly metallic tints, Elachista recurva is never¬ 
theless one of the most brightly marked and beautiful of the 
Microlepidoptera of the island. 
Genus 41. Lithocolletis, Zell. 
Lithocolletis aurifascia. 
Lithocolletis aurifascia, Walk., in Melliss’s St. Hel. 192 (1875). 
This exceedingly pretty and peculiarly marked little Litho¬ 
colletis is a somewhat difficult species to describe accurately, 
not only on account of its minute size, but likewise from its 
slightly variable markings, especially towards the apex, where 
the characteristic fascite are much broken up and confused. 
Nevertheless the first two or three alternate paler and darker 
oblique markings are generally quite distinct throughout the 
width of the wing. As this was the only member of the 
present genus which we met with after a most careful search,
