LEUCANIA PUTRESCENS. 25 



ichneumons, &c, only one healthy larva went to earth, 

 (12th of October), retiring half an inch under the sur- 

 face, close to the roots of a tuft of a common grass 

 (Poa annua), on which it had previously fed, and spin- 

 ning a cocoon with particles of mould. 



The moth appeared August 3rd, 1865, a well-marked 

 specimen. 



The larva was of a pale greyish-ochreous tint gene- 

 rally, striped longitudinally after the manner of its 

 congeners. The head mottled with dusky grey and 

 ochreous, with a black streak bordering the front of 

 each lobe, followed by a white streak on each side of 

 the central portion. Dorsal line whitish, conspicuous 

 only on the second, third, and fourth segments, after- 

 wards nearly obliterated by the dusky edging enclosing 

 it ; and on either side a dorsal broad stripe of mottled 

 greyish-ochreous, followed by a pale ochreous stripe, 

 and a greyish-ochreous darker stripe. The subdorsal 

 line whitish, very finely edged above and below with 

 dusky greyish-brown, followed by a broad stripe of 

 mottled ochreous, then a lateral whitish line, finely 

 edged with dark greyish-brown ; below this a broad 

 greyish-brown stripe, the spiracles being situated 

 along its lower edge, the belly and legs pale ochreous, 

 The ordinary spots and spiracles black. The shining 

 plate on the second segment dusky between the lines.

Leucania littoralis. 

 Plate LIX, fig. 1. 



On the 13th of May, 1864, I found full-fed larvse of 



Leucania littoralis at roots of Ammophila arundinacea ; 

 I have met with these larvae for some years, having 

 first, accidentally, in 1861, captured a small one, which, 

 after feeding up and being duly figured, was reared ; 

 when very young their colour is glaucous green, with
