or on the leaf-stalk, of Malva sylvestris (common mallow), on 

 which plant it feeds : when annoyed it tncks in the head, 

 forming the anterior part of the body into an Tonic volute, 

 which becomes tighter as the annoyance continues, until at 

 last the claspers lose their attachment, and the larva falls to 

 the ground, a compact but not uniform ring, which closely 

 resembles the curious seed of the mallow, so familiar to all 

 of us, when children, under the name of "cheeses:" when 

 stretched out at length and rigidly straight it has an equal 

 resemblance to the leaf-stalks of the same plant. Head rather 

 narrower than the 2nd segment, scarcely notched on the 

 crown, and semiporrect : body cylindrical, slightly scabrous, 

 the scabrosity caused by the presence of minute warts, some 

 of which are somewhat larger than the rest, and emit a bristle 

 from the summit ; on each segment there are usually six of 

 these bristle-bearing warts, four of them arranged in a dorsal 

 quadrangle. Colour of bolh head and body opaque apple- 

 green, the latter with a medio-dorsal narrow and indistinct stripe 

 of a smoky green hue, evidently due to the presence of food 

 in the alimentary canal ; the warts are white : the ventral is 

 concolorous with the dorsal surface, and the claspers are of 

 the same hue, but the legs are almost colourless, very nearly 

 transparent. The larvas, kindly given me by Col. Stewart, 

 were full-fed on the 6th of June, and on that day retired 

 below the surface of the earth to undergo pupation. — Edward

Description of the Larva of Notodonta trepida. — Some- 

 times rests with the head and anterior segments thrown back 

 on those which succeed ; this posture is not invariable, and 

 seems assumed from irritation and annoyance rather than for 

 rest. Head as wide as the 2nd segment, the crown elevated, 

 scarcely notched ; bod}' smooth, almost uniformly cylin- 

 drical, without humps. Colour of the head apple-green, with 

 four pale stripes down the face, the median pair somewhat 

 approximate towards the crown, more widely separated 

 towards the mouth ; mouth and a conspicuous mark on the 

 lower portion of the cheeks brown : body apple-green, the 

 dorsal surface slightly glaucous ; two narrow approximate 

 yellowish while stripes down the back, extending the entire 

 length, but interrupted at the anterior extremity ; exterior to 

 this double stripe, on each side, is an irregular and very
