belly, gradually shading off into the blackish ground 
colour. 
My larvee fed on Polygonum aviculare, and when at 
rest, the food-plant was grasped by the claspers, and 
the body stretched out at full length, with the head 
raised to a considerable height; when disturbed 
they fell to the ground at full length rigidly stiff, 
not attempting to roll into a ring. (George T. 
Porritt, July 12th, 1871; Hnt., August, 1871, V, 360.) 
ACIDALIA STRIGILATA. 
Plate CXIX, fig. 4. 
On the 28th of August, 1870, I received from my 
friend Mr. J. P. Barrett, of Peckham, eight young 
larvee of this insect, obtained from eges deposited by 
moths captured by him during the previous month at 
Folkestone. They fed on Polygonum aviculare until 
autumn, when they began to hybernate, having attained 
the length of about three-quarters of aninch. At the 
beginning of April, not being able to procure knot- 
erass for them, dandelion was substituted, on which 
they at once commenced to feed, showing a preference 
for the withered leaves. By May 12th the only larva 
I had left had reached an inch and a quarter in length, 
and on June 2nd, it being nearly full-grown, I took 
down the following description : 
Length nearly an inch and a halt, cylindrical, very 
slender, and tapering slightly towards the head. Head 
not notched on the crown, about as wide as, perhaps 
a little wider than, the second segment; the face 
slightly flattened, and the cheeks globular. Skin 
ribbed transversely, which gives it a rather rough 
though uniform appearance. | 
The ground colour is grey, tinged with green; the 
head grey, faintly variegated with very pale brown. 
Of the longitudinal stripes, the most distinct is the 
narrow, dull green, medio-dorsal line; the subdorsal
