Mrs. T. Vernon Wollaston on 
of its anterior wings is adorned, added to the pure white apices 
of its long and black antennae, giving it a character which it 
is impossible to mistake. 
Genus 38. Endrosis, Htibn. 
Endrosis lacteello , Staud. 
This common European species has become naturalized in 
St. Helena; notwithstanding, we did not observe it there in 
any very great abundance. 
Genus 39. Cosmopteryx, Htibn., Staint. 
Cosmopteryx Jlavofasciata, E. Woll. 
Expanse 34-4^ lines. With the labial palpi much curved, 
very divergent, and pointed at the apex; head smooth and 
having the forehead convex. The fore wing nearly black, 
but ornamented with a broad and conspicuous yellow post¬ 
median fascia, which is bordered on either side with bright 
silvery metallic scales. Within the fascia, on either extre¬ 
mity, there are usually two or three minute black specks. 
The antemedian portion of the wing contains several white, 
or silvery, excessively minute, thread-like longitudinal lines; 
and on the costa, towards the apex, there is a small white 
line, as well as a similar but more oblique and larger one 
from the apex. Hind wings very narrow and of a blackish 
smoky hue. Head and thorax black, but marked with a few 
minute longitudinal white lines. 
A most elegant little moth, easily recognized by the fact of 
its narrow blackish fore wings being brightly ornamented 
with a transverse yellow band, edged (on either side) with 
scales of a shiny silvery hue. It is decidedly a common 
species at St. Helena, particularly at intermediate altitudes, 
though ascending also to the central ridge. Most of my 
examples were captured at Plantation, where it was abundant 
in grassy places and amongst herbage ; but I also met with it 
at Cleugh’s Plain, which is at least 500 feet lower than Plan¬ 
tation. 
Mr. Stainton observes of this species that it comes very 
near to the European G. scribaiella , Zell. 
Genus 40. ElACHISTA, Treit., Staint. 
Elachista recurva , E. Woll. 
Expanse 3^-4 lines. With the maxillary palpi nearly as 
long as the labial ones, but thread-like and very much con-
