Lak\.\. Ileiul slif,'litly divided on the crown, as broad as 

 the body, which is uniformly cylindrical, without humps or 

 warts. J lead yellowish-green, with mottled black markings ; 

 body yellowish or bright green, with two black dorsal stripes 

 scarcely so broad as the green median space between them : 

 spiracles black ; legs and prolegs pale green ; all parts of the 

 body emitting fine short scattered black hairs. (E.Newman.) 

 In one of Mr. W. Buckler's figures the subdorsal stripes arc

July and August, and sometimes till the beginning of 

 September, on Claliuni rrrinn and G. iiiollut/o, feeding upon 

 the flowers and unripe fruits. When not feeding remaining 

 upon the plant, often stretched across from one portion of 

 inflorescence to another, greatly resembling the stiff' straight 

 twigs, and by no means easy to see. 



Pupa short and thick, reddish, with very broad dark brown 

 wing covers. (Hofmann.) In a tliin silken cocoon in the

 in Kent, Sussex, Hants, Dorset, Devon, and once in Coi-n-

 Suffolk, and Norfolk ; possilily more widely distributed, but 

 from its secret habits overlooked, since a specimen, which ]

 by the late Jlr. Blatch ; but I have no record of it in AVales 

 or in any of the more northern counties of England. In
