Mrs. T. Vernon Wollaston on 
of Duponcliel’s 1 Histoire Naturelle des L^pidoptkres ou Papil- 
lons de France’ (pi. 220) are quite identical with my St.-Helena 
examples ; and one of my specimens even approaches rather 
near in colour to his figure of M. diver sail's in the same volume 
(pi. 233); hut there is more black on the hind wings of the St.- 
Helena one. 
Genus 27. Scopula, Schr. 
Scopula ferrugalis , Hiibn. 
I did not meet with this little moth at St. Helena ; but 
since Mr. Walker identified it from amongst the material 
which was collected in the island by Mr. Melliss, 1 can 
scarcely do otherwise than admit it into the present catalogue. 
I am bound, however, to add that I cannot but feel it doubt¬ 
ful whether Mr. Walker, who does not always appear to have 
been precise in his determinations, may not have mistaken 
one of the smaller specimens of the following rather incon¬ 
stant species for S. ferrugalis ; however, the two insects are 
most thoroughly and permanently distinct. 8. ferrugalis 
occurs in Europe, and is exceedingly abundant in Madeira; I 
have also received specimens of it from North Africa, col¬ 
lected there by the late Mr. Trovey Blackmore. 
Scopula delineatalis. 
Scapula delineatalis, Walk, in Melliss’s Saint Hel. 189 (1875). 
This is a most universal insect in the intermediate districts 
of St. Helena, occurring at about the altitudes of Plantation 
and Oakbank almost everywhere, and ascending up to the 
highest parts of the central ridge. In fields and on open 
grassy slopes it is often extremely common, starting into 
flight in the daytime as one passes its locality. But the 
particular spot in which I met with it in the greatest profu¬ 
sion is a little ravine between Oakbank and Ilutt’s Gate, and 
below Halley’s Mount, called Vine-Tree Gut, where some¬ 
times it was in great abundance, flying over the curious 
Lachanodes prenanthiflora (or “she cabbage tree”), which 
grows plentifully in that particular ravine. 
Genus 28. Prionapteryx, Steph. 
Prionapteryx Whiteheadii , E. Woll. 
Expanse 4-5 lines. With the fore wings of a dull whitish 
hue and having numerous ill-defined longitudinal, brownish, 
somewhat powdered streaks. There are two transverse indi¬ 
stinct lines, the first one of which is near to the middle, very
