90 ACIDALIA SCUTULATA. 
ACIDALIA SCUTULATA. 
Pl. OXVII, fig. 2. 
Hees laid July 12th, 1867; larve hatched on the 
17th; ate withered dandelion, and in the spring 
seemed very fond of a mouldy slice of turnip, which 
had been put into their flower-pot to catch an in- 
truding slug; spun up during May and June; moths 
out June 8th to July 2nd. 
The egg of A. scutulata is rather longer in shape 
(than that of A. holosericeata), one end flattened, the 
other more conical, covered with minute pits or de- 
pressions ; colour whitish, mottled with brownish-pink. 
The larva, though still belonging to the stiffer type 
of Acidalia larvee, is yet an advance toward the other, 
being more slender and elongated in form, than that 
of A. holosericeata, while still retaining the spiracular 
ridge, the great rugosity of skin, and the taper- 
ing to the head. When full-grown, about three- 
quarters of an inch long; slender, flattened, front 
segments more rounded, head notched and move- 
able; the front and hinder segments very short, so 
that the legs appear as if placed close together at 
either extremity. In repose it keeps the front seg- 
ments bent down, but the head and neck turned up 
again, in an uncomfortable-looking attitude, suggestive 
of a “‘crick”’ in the neck. Colour pale ochreous, a 
brown double dorsal line showing strong on the head, 
faint on the front segments, confluent and strongly 
marked behind; a brown subdorsal line very plain 
and strong on the head to the fourth segment, then 
almost lost till it becomes strongly marked again on 
the hinder segments, but its place is marked at the 
seemental folds by a pair of dots; on segments five to 
nine pale brown oblique dashes reaching from the 
dorsal to below the subdorsal line; the spiracles black, 
placed on a whitish ridge; belly darker than the back,
