and each segment is also transversely ribbed, and 1s 
clothed with very few, scattered, short, bristly hairs. 
Ground colour a dirty, dull, smoky brown, marbled 
and variegated with ochreous-yellow, the darker 
colour predominating on the front segments, the 
ochreous on the ninth to thirteenth segments. The 
head is also of these two colours, in about equal pro- 
portion. Dorsal line ochreous, deeply edged with 
smoke-colour; there is a distinct white spot on the 
posterior part of the sixth, seventh, and eighth seg- 
ments. ‘here are no perceptible subdorsal lines, but 
a conspicuous ochreous line extends through ‘the 
region of the spiracles. The ventral surface is of the 
same dull, dark, smoky brown as the dorsal area, but 
has a very pretty series of large, ochreous, crescentic 
marks throughout its entire length, and there is a 
very faint indication of a pale central line; the hairs 
are black. 
This larva spun a shght cocoon of loose threads, 
and the imago, a fine female specimen, emerged 
August 4th. (George T. Porritt, February 6th, 1878 ; 
Ent., April, 1878, XI, 91.) 
Egos OleAe interjectar iad (as we must now call what 
used to pass in this locality for A. osseata) were 
obtained here (Hixeter) on July 12th, 1867; others 
were sent me by Mr. Brown, of Pompuges on the 
17th July. 
The larve hatched on the 24th and 26th ; fed on 
dandelion and scarlet pimpernel, preferring withered 
leaves, and indeed would eat almost anything ; withered ; 
spun up in May, 1868, and the moths appeared June 
24th to 29th. 
The egg of A. wterjectaria is flattened at either 
end, but not so decidedly (as in A. holosericeata), the 
reticulation finer, the colour pinkish. 
The larva of A. interjectaria 1s also one of the short 
stiff larvae, in figure much like A. holosericeata. When 
full-grown its length is about half an inch; tapering 
towards the head, which is small, notched, and move-
