on each side just below the spiracles, and touching all of them 

 except the 1st and 9th, is a pale stripe, internipled by a 

 darker stripe ; claspers and legs concolorous with the body, 

 I am indebted to Mr, Greening, of Warrington, for the op- 

 portunily of describing this larva. — Ediiard Newman. 



Description of the Larva of Hndena tlialassina. — The 

 time and manner of oviposilion, as well as the natural food- 

 plant, are unknown to me. The larva feeds freely in confine- 

 ment on Polygonum aviculare (common knot-grass) by night, 

 almost invariably retiring just below the surface of the earth 

 by day : I once observed a specimen at rest, stretched at full 

 length on one of the stems of knot-grass during the day, with 

 its back downwards, and its anal claspers stretched out be- 

 hind, but still grasping the food-plant : on being touched it 

 instantly rolled in a compact ring. Head rather narrower 

 than the 2nd segment, porrected, highly glabrous : body 

 almost imilorraly cylindrical, but slightly attenuated ante- 

 riorly, velvety ; 12th segment slightly gibbose dorsally. 

 Colour of the head pale dingy brown, delicately reticulated 

 with darker brown ; body dull brown, tinged with pink ; 

 every part beautifully and delicately reticulated with dark 

 umber-brown, which colour forms a pair of oblique subdorsal 

 mai kings ; these pairs are indistinct towards the head, but 

 increase in intensity to the 12ih segment, on the back of 

 which they are united ; on each side immediately below the 

 spiracles, which are almost white, is a well-defined light 

 stripe, conspicuously tinged with pink ; the upper margin of 

 this lateral stripe is delicately bordered with white ; the 

 stripe itself is reticulated, but not so conspicuously as the 

 dorsal surface ; ventral surface, legs and claspers slightly 

 paler and more semilransparent than the back, dotted and 

 reticulated. Changes to a pupa, just beneath the surface of 

 the earth, at the end of July : the moth appears on the wing 

 iu the following June. I am indebted to Mr. Doubleday for 

 a supply of this larva, — Id. 



Description of the Larva of Amphipyra Tragopogonis. — 

 Feeds freely on Crataegus Oxyacantha (whitethorn). Rests 

 with its back slightly incurved, the extremities being some- 

 what elevated, but not so cons})icuously as in the Notodon- 

 tida). Head narrower than the 2nd segment, into which it is 

 partially received : body smooth and velvety, almost uniformly
