HYRIA AURORARIA. 69 
dorsal line, commencing very fine and faint behind the 
head, but on segments five to nine suddenly growing 
thicker both in the middle of each segment and at 
each segmental fold, so as to form a series of nine 
pairs of dark curved dashes (alternately curving in- 
wards and outwards); on segments ten to twelve 
the dorsal lines become continuous again, but strong 
and distinct; the blackish subdorsal line 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 seements five to nine; the ventral and anal lege 
tinged with blue. 
‘he 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 ochreous, wings finel 
outlined in black. (John Hellins, October 8th, 1867 ; 
H.M.M., December, 1867, IV, 158.) 
I am much pleased to be able to send a description 
of this species; and for the opportunity of doing so 
I have to thank Mr. John Harrison, of Barnsley, who 
gave me a dozen larve on the 4th of September, 1875, 
and further sent me a supply of eggs on the 19th 
of July last. 
The egg is large for the size of the moth, is oblong- 
square, with the edges rounded, and considerably 
depressed on the upper side; the colour at first pink, 
afterwards olive-brown. 
The young larve fed, but grew slowly, on knotgragss 
until autumn, when they ceased feeding, and remained 
rigid on the sides of the cage or on bits of stick, etc.,
