f?reen. Feeds on Betula alba (bircli), Acer campestris (maple), Quercus Robur (oalc\ 

 &c., is full fed on the 20th of September ; it spins a slight cocoon on the surface of 

 the earth, and remains in the pupa state all the winter. — Edward Newman. 



Description of the Larva of Nolodonla dictcea. — Does not roll in a ring or feign 

 death when disturbed, rests in nearly a straight posture, as when crawling. Head 

 rather large, very slightly notched on the crown, shining, pale green; body almost 

 uniformly cylindrical until the J2th segment, which is humped, the hump terminating 

 in a moderately sharp point; body whitish or glaucous-green on the back, a broad 

 paler green stripe on each side, and adjoining it a narruw raised yellow-green stripe 

 just below the spiracles, and touching all of them except that on the 12ih segment, it 

 extends the entire length of the insect, terminating in the anal clasper ; on the summit 

 of the 12th or humped segment is a black transverse line. Feeds on Populus nigra 

 (black poplar), Salix capraea (sallow), Betula alba (birch), &c. ; is full fed on the 22nd 

 of September: spins a slight web on the surface of the earth, attaching the upper part 

 of the web to a fallen leaf; it remains in the pupa state throughout the winter. 

 There is a very common variety of this larva, plain brown without the slightest 

 appearance of the lateral stripe: this after the last change of skin. — Id. 



Description of the Larva of Notodonta diclcBoides. — Does not roll in a ring or 

 feign death when disturbed ; rests in nearly a straight posture, as when crawling. 

 Head rather large, being slightly notched on the crown, brown, shining. Body almost 

 uniformly cylindrical until the 12th segment, which is humped, the hump terminating 

 in a somewhat sharp and very shining papilla; the 13th segment is rugose above; 

 back purple-brown, very shining when full fed ; on each side is a distinct yellow stripe, 

 which includes the spiracles, excepting that on the 12th segment; the spiracles are 

 black ; the belly is much paler than the back. This larva, when compared with that 

 of Notodonta dictaea, may be distinguished by its somewhat more slender proportions, 

 by its more glabrous skin, by its uniformly possessing the purple-brown hue, and by 

 the greater brightness and distinctness of the lateral stripe. Feeds on Betula alba 

 (birch), and is full fed on the 27ih of September, when it descends to the ground, 

 spinning a slight cocoon between the surface of the earth and a fallen leaf: it remains 

 in the pupa state all the winter. — Id. 



Description of the Larva of Notodonta Dromedarius. — Does not roll up in a ring or 

 feign death when disturbed ; rests with both extremities elevated, and its anal claspers, 

 which are rather long, porrected, but these can be used in walking when required. 

 Head manifestly larger than the 2nd segment, bifid at the crown, the lobes blunt and 

 rounded; shining brown, speckled with darker brown, the sides rather paler: body not 

 regularly cylindrical, but uneven, humped on the 5th, 6lh, 7th, 8th and 12th segments; 

 the hump on the 8lh segment is the least, those on the 5th, 6th, 7th and 8th have ob- 

 tuse summits directed backwards; that on the 12th segment. is erect. Colour of the 

 body yellow-green, with purplish brown markings, which form a conspicuous stripe ou 

 the back of the 2nd, 3rd and 4th segments, and which crown all the five humps and 

 till the interstices between the 2nd and 3rd, and 3rd and 4th ; on the fifth hump this 

 purple-brown colour forms a mere line, and there is a similar line ou the last or 13th 

 segment: a very similar colour occupies nearly the whole of the belly, which is darkest 

 on the 10th, 11th and 12lh segments. It feeds on Betula alba (birch), and is full fed 

 on the 29th of September, when it descends the tree and generally spins a slight 

 cocoon on the learth, attaching the upper side of the cocoon to a fallen l.af : in this 

 situation it remains in the pupa state all the winter. — Id.
