seeds of Yarrow (Achillect, millefolivm) growing near the sea, whicli appeared 
identical with the larvae on golden rod, now proved to be osteodadylus ; and the 
mention of this fact has also made me recollect that I have occasionally beaten one 
or two of them from naugwort, Artemisia vulgaris ; but in neither case did I succeed 
in breeding the moth. — J. H., October 8th, 1867. 
Notes on Hyria anroraria. — This species is not one of the urikriowns, still I 
venture to send you my notes on it, since the larvse I have seen differed not only 
among themselves, but also from the description given in the Manual after Guenee- 
In August, 1865, Mr. Batty, of Sheffield, sent me some young larvse, which 
were then, and continued afterwards, of a very dark variety. In 1866, Mr. T. Brown, 
of Cambridge, sent me some eggs, the larvae from which were very much paler than 
the former brood. I find the following dates recorded in my note-book : — Larvse 
hatched July 12th ; about half-an-inch long in October ; began to feed after hyberna- 
tion about the end of February ; full-fed about the beginning of June ; moths bred 
during the first half of July. 
These larvae fed on Polygonum aviculare, and, although very much of the 
Acidalia fonn and habit, did not, as many species of that genus do, show any 
preference for withered leaves over fresh. All, save one of the Sheffield brood, died 
during the winter of 1865-6, whilst, as far as I could see, the much sharper frost of 
last winter made no impression on the Cambridge brood, which fed up well, though 
about a third of their number died in the final change. 
The Sheffield larvae, when small, were very dark brown — almost black — all 
over, but with a lens a slightly paler sub-dorsal line could be discovered, as well as 
some black dorsal central spots placed in a slightly paler space. The Cambridge 
larvee, whilst small, came near to the Manual description, for they were then 
dusky -brown, with the anterior segments pale ochreous on the back, and the middle 
segments having pale diamond marks enclosing a central dusky spot ; but the full- 
grown appearance was quite different. 
When full-grown, the larva is about f inch long, slender, rather flattened along 
the spiracles, tapering towards the head, which is small and bifid ; the skin a little 
wrinkled ; in fact it is a slender form of the shorter (or aversata) type of Acidalia. 
The ground-colour either brown or very pale grey ; in either case the anterior 
and posterior segments are much tinged with ochreous ; a dark, blackish, double 
dorsal line, commencing very fine and faint behind the head, but on segments 5 to 
9 suddenly growing thicker both in the middle of each segment and at each seg- 
mental fold, so as to form a series of nine pairs of dark curved dashes (alternately 
curving inwards and outwards) ; on the segments 10 to 12 the dorsal lines become 
continuous again, but strong and distinct ; the blackish sub-dorsal lino distinct on 
the front and hind segments, but splitting into two or three faint irregular threads 
on the intermediate ones ; one larva had also a strong black spiracular stripe 
beginning at the fourth segment, and ending at the anal pair of legs ; spiracles 
black ; the belly darker than the back, with a pale central line, and between it and 
the spiracles some curved oblique dark streaks, and a row of five black dots just 
below the spiracles on segments 5 to 9 ; the ventral and anal legs tinged with blue. 
The larva makes the merest apology for a cocoon, just drawing together with 
the greatest economy of silk a few bits of moss and grass, between which the pupa 
can be easily seen ; this is slender, cylindrical, very smooth, with the wing-cases 
short and distinctly marked ; colour a pale dull ochi-eous, wings finely outlined in 
black. — Id.
