PTEROPHORIDiE. 55 



The larva feeds in autumn and May on rest-harrow 

 (Ononis), hedge- woundwort [Stachys sylvatica), wild 

 basil [Calamintha clinopodium) , Mentha, Sic. It pupates 

 suspended from the stem of its food-plant. 



The larva is pale green, with two white dorsal and one 

 lateral stripe, plentifully covered with hairs and bristles ; 

 head yellowish ; mouth darker. Dr. Ilofmann. 



The following is a description of a larva bred by Mr. 

 South at Ventnor on Stachys sylvatica, feeding on the 

 flowers and unripe seeds ; they produced in September 

 an intermediate form between acanthodactyla and cos- 

 modactyJa, which Mr. South considers to be identical 

 with the Plume bred by Prof. Frey from the same plant 

 and named by him cosmodudyla, var. stachydalis. 



Description of larva referred to above : — Head pale 

 olive-green ; crown and cheeks freckled with blackish ; 

 mandibles reddish brown. Ground-colour darkisii 

 gi'cen ; alimentary canal darker. Dorsal tubercles four 

 on each segment, from each of which two bristles of 

 unequal length are emitted ; subdorsal, two warts on 

 each segment, the anterior with two and the posterior 

 with one whitish hair ; spiraeular, one dark green wart 

 with two whitish hairs on each segment; there are 

 minute blackish bristles scattered over the entire dorsal 

 and ventral areas ; dorsal and subdorsal warts seated on 

 linear patches of a yellowish colour ; prolegs blackish ; 

 anal claspers scmitransparent, with greenish tinge. 



Pupa attached by the tail to stem of food-plant, 

 generally near the flower-whorl; it is at first of a 

 greenish colour, but changes to an obscure reddish 

 brown ; the leg-eases are detached from the abdomen ; 

 head truncate; two conspicuous points on back. R. S.
