pink ; a dull pinkish plate on the second segment. One olive-green larva had the 
plate dark red, and a large crimson spot on the top of each lobe of the head. 
2. Ground-colour cinnamon-brown ; a narrow pale greenish-yellow stripe be- 
neath the spiracles ; the folds of skin at the segmental divisions greyish ; dorsal 
stripe faintly indicated by a dusky spot at the beginning of each segment ; the 
sub-dorsal stripe more distinct and faintly blackish. 
3. Deep dingy crimson on the back and sides ; below the spiracles a greenish- 
yellow stripe ; the belly and legs, with head and dull plate on second segment, 
rather paler than the back ; a broad dorsal and narrow sub-dorsal stripe of faint 
blackish, but just at the beginning of each segment quite black. 
4. The whole of the back between the sub-dorsal lines a brilliant deep citron- 
yellow, the sides from the sub-dorsal to the line of spiracles of the same ground- 
colour, but almost entirely suflFused with dark red ; the head and thoracic segments, 
with the anal extremity, also suffused with red. The dorsal stripe composed of 
two red confluent lines forming a broad stripe, with blunt arrow-head shapes of red 
at the beginning and end of each segment, and anteriorly margined with short 
black streaks ; the tubercular dots black, the anterior pairs being much the largest ; 
sub-dorsal line black, and interrupted in the middle of each segment. 
Spiracles white in semi-lunar blotches of black, and edged below by a pale 
greenish-yellow stripe ; belly greenish, with a large red blotch along the sides 
above the legs, the latter being orange-red. — Id. 
Notes on the earlier stages of Acidalia etn.Mfcwia.— Through the kindness of 
Messrs. Fenn and A. H. Jones, I am enabled to give some account of the earlier 
stages of this species. 
The egg-laying female was captured on the 13th July, 1866, in a cultivated 
marsh, flying amongst the reeds which line the sides of the dykes. This locality 
would point to some marsh-plant being its natural food, but we reared our larvae 
in confinement upon Medicago lupulina, Lotus cornicula.tus, and Polygonum aviculare. 
My larvae hatched July 22nd, 1866 ; hybernated when about one-third grown ; 
began to feed again about the end of February, 1867 ; moulted twice during April 
and May ; spun up in the second week of June ; and the moths appeared on July 
7th and 10th, full-sized specimens, and one of them esjDecially deserving Haworth's 
name of suhroseata. 
The eggs are of an elongated pear-shape, the stalk-end being cut off" flat ;* 
ribbed longitudinally, and finely punctured : when first laid their colour is pale 
bluish-green, afterwards changing to a straw colour with spots and irregular 
splashes of pink. 
The little slender larvas, when first hatched, are pale greenish, with pinkish 
heads ; afterwards becoming very plainly coloured — pale ochreous-grey, with a few 
dingy black lines and markings. 
One of my four larvae died early in winter, but the other three bore the cold 
very well, whilst in the same outhouse the extreme fi-ost slew some of the more 
tender species of hybernating larvae — Agrotis ripce and lunigera for example. I had 
• N.B.— I notice that the eggs of several species of Acidalia exhibit this truncated form at one or 
both ends.
