segments have each a transverse dorsal series of warts ; the 

 following segments, from the 5th to the 11th, both inclusive, 

 have each four warts placed nearly in a quadrangle, but the 

 anterior pair are always nearer together, and also rather 

 smaller than the posterior pair; the 12th segment, like the 

 2nd, 3rd and 4lh, has a transverse series of warts, of which a 

 median pair are conspicuously the largest ; every wart emits 

 a bristle from its summit ; there is a pair of claspers on the 

 9th, as well as on the 10th and 13lh segments ; those on the 

 9th segment are smaller than the others, and appear retrac- 

 tile, sometimes disappearing as the larva crawls. General 

 colour of the head and body dingy brown, the 7th and 8ih 

 segments having each an indication of two dark transverse 

 bands ; ventral surface almost white, in some specimens 

 tinged vA'ith green. Beaten in Epping Forest on the 13th of 

 May, 1864, when it was lull-fed. 1 have beaten this larva in 

 Birch Wood, &c., about the middle of May. — E. Netcman. 



Description of the Larva of Hemiihea thymiaria. — Rests 

 in a perfectly straight position, at an angle of forty-five 

 degrees with the twig, which it clasps with its anal claspers, 

 the head tucked in and the mouth appressed to the legs. 

 Head as wide as the 2nd segment, scabrous, deeply notched 

 on the crown, the lobes being conical and directed forwards: 

 body scabrous, the scabrosity consisting of elevated papillae 

 which are blunt at the tip ; 2nd segment with two dorsal 

 conical protuberances directed forwards, and closely re- 

 sembling those of the head ; this, as well as the 3rd and 4th 

 segments, is extremely uneven and wrinkled. Colour of the 

 head dark brown ; prevailing colour of the body the same, 

 but considerably variegated, and having the 7th, 8lh and 9th 

 segments suffused vvitli olive-green : the papillae are brown 

 or white ; the white ones form longitudinal series on the 4th 

 and 5th segments, and a V-shaped marking on the 6th and 

 7th : in some specimens the colours are bright, and the 

 purple-brown and green and white form a beautilul contrast; 

 in others the colours are rather obscure and indistinct. When 

 full-fed, which is between the 20lh and SOlh of May, it spins 

 together the leaves of the whitethorn, forming a loose web, 

 and in this changes into a pupa, which is slender in pro- 

 portion to its length ; the abdomen particularly slender and 

 tapering : the head has two small approximate ears ; the
