THE ENTOMOLOGIST. 193 



otherwise annoyed, it relaxes its hold and falls to the bottom 

 of the vessel, rolled in a compact ring, which position it will 

 persistently maintain for some minutes. When full fed, 

 which period arrived to my specimen on midsummer day, the 

 head is slightly narrower than the second segment, scarcely 

 notched on the crown, very glabrous, and emitting a few 

 scattered hairs, which are mostly directed forwards : its 

 general position is semi-prone, but sometimes, when stretched 

 forward and waved about in the manner common to Noctua 

 larvae, it is porrected almost on a plane with the body : the 

 body is almost uniformly cylindrical, but has a slight lateral 

 skinfold ; its surface is velvety, and emits a few scattered 

 hairs, more especially about the anal flap and aperture. The 

 colour of the head is dull pale green tinged with brown, and 

 semi-transparent; the ocelli are black and conspicuous: the 

 dorsal area of the body is dull olive-brown, obscurely tinged 

 with pink, and delicately reticulated with vermicular markings 

 of a darker tint ; there is a double and very narrow medio- 

 dorsal stripe of the same darker colour, and the very slender 

 interval between the component moieties of this double stripe, 

 as well as the region i-mmediately adjoining the boundaries of 

 the stripe, is paler than the general dorsal surface ; these 

 markings are inconspicuous, as well as the ordinary trapezoid 

 dots on the dorsal surface of each segment, each of which dots 

 is slightly paler than the surrounding area, and has a black 

 central dot which emits a hair ; at the incisions of the seg- 

 ments is a transverse green line, very narrow, very slender, and 

 interrupted in the middle by the double medio-dorsal stripe 

 already described ; the lateral skinfold is pale, almost white, 

 constituting a narrow stripe which is continuous from the 

 head to the anal claspers; the lower portion of this pale stripe 

 is slightly tinged with pink ; it passes directly through the 

 region of the spiracle, the 1st and 9th segments of which are 

 just above it, and the others seem to rest on its upper margin ; 

 these spiracles are oblong,"" and of a rich olive colour, with a 

 very slender and delicate black circumscription ; the ventral 

 is paler and greener than the dorsal area, but the transition is 

 gradual, the tint below the lateral stripe differing but little 

 from that immediately above it, and being equally decorated 

 with vermicular reticulations; the belly itself is green without 

 these markings; the legs and claspers are of a dingy pale
