nigrescens, Tutt. The colour of the forewings, however, is not 
‘ blackish grey ’ neither is it ‘ black,’ but ranges from greyish, 
brown (No. 3) through dark brown (Nos. 4-5) to blackish brown 
(No. 6); the pale edging of the transverse lines is distinct in 
all the specimens. 
“ Recently there has been a report that melanic specimens of 
L. gueneei had been obtained this year on the Lancashire coast. 
The darkest specimen of the species that has come under my 
notice is No. 15 in the series now exhibited, and even this- 
is very little darker than tyjiical gueneei, but there is little 
ochreous in its coloration. Probably the rumour arose from 
some error in identification, as in the present case. 
“ The two species are somewhat similar in a general kind of 
way, but among other points of difference that might be 
mentioned, two stand out clearly, and study of these should 
enable us to easily distinguish one species from the other. 
“ In testacea the subterminal line is excurved between veins 
5-7, outwardly angled at vein 3, thence incurved to the 
dorsum; the area beyond the line is nearly always darker 
even in dark specimens, than the general colour. The same 
line in gueneei (usually edged with white on the costal area) is 
not angulated at vein 3, and the outward turn between veins 
5-7 is not curved, but forms a square bracket; the area beyond 
the line is not darker than the general colour, but often much 
paler, even whitish.” 
Oria musculosa in Britain. —Mr. South also exhibited 
three of six specimens of Oria {Synia) musculosa, taken in the 
Salisbmy district, in August 1909, by Mr. H. Haynes, who 
captured three others in August of the present year. The hind- 
wings of the specimens exhibited are darker than are those 
of any other British or Continental specimen seen by the 
exhibitor, with the exception of one rather small specimen 
from Capri, in the British Museum Collections. 
The species is undoubtedly scarce in Britain, and most of the 
specimens recorded, or about which anything is definitely 
known, have been taken in Sussex, chiefly on the coast, and 
at long intervals between the years 1855 and 1883. Single 
examples have been recorded from Kent and S. Devon, the 
latter in 1899. The range of 0. musculosa would seem to
