LOZOGRAMMA PETRARIA. 139 
seems to be covered with very slender chocolate- 
brown longitudinal lines—I could count at least 
twenty-four all round the body, but on examination it 
is seen that these are arranged in pairs; thus there 
is a double dorsal and three double subdorsal lines, 
the lowest being darkest and thickest. The spiracles 
are black, and below them is a creamy white line; the 
belly is striped somewhat like the back, only that the 
lines are more diffuse and not so numerous; the 
segmental folds are red. (John Hellins, July, 1864; 
H.M.M., August, 1864, I, 71.) 
SELIDOSEMA PLUMARIA. 
Plate CXXII, fig. 3. 
Several specimens of this species which I took in the 
New Forest, on the 31st of July last year (1877), de- 
posited eggs. ‘These began to hatch during the third 
week in August, and the larvee fed well until autumn 
on the common ling. By the first week in December 
the largest specimen was about an inch long, but the 
majority were from half to three-quarters of an inch. 
They fed sparingly on withered ling shoots and leaves 
through the winter, and by the end of March the 
largest was nearly full- -orown. 
Length about an inch and a quarter, and moderately 
stout in proportion ; head narrower than the second 
segment, into which it can be partially withdrawn ; it 
has the face flat, and there is a slight depression on 
the crown. Body of nearly uniform width through- 
out, and cylindrical; the segments overlapping each 
other, however, and each being divided into sections 
by transverse ribs, together with a somewhat pro- 
minent ridge along the spiracles, give it a rather 
uneven appearance; the anal segment ends in a 
rather sharp triangular appendage, and the anal legs, 
being set widely apart, are very conspicuous; skin 
smooth, but tough in texture.
