226 LEPIDOPTERA HETEROCERA 
Lanva. — Rigid, twig-like, beautifully assimilating during hibernation and subsequently to the 
winter and spring coloration of its food-plant (Clematis); head produced to two sharp points, prothorax 
produced to two horns projecting over the head; body transversely wrinkled, shagreened (or frosted, 
each point of the shagreen being tipped with white), with strong lateral flange; anal flap produced to a 
point (Newman, loc. cit. ; Wackerzapp, Sfett. Ent. Zeit. Vol. 50, p. 282). 
PuPa. — Not fully described. Green, the thorax smooth, but punctured. Suspended in loose 
cocoon among leaves (Newman, loc. cit.). 
A not very sharply defined genus, which could, with almost equal propriety, be either enlarged 
or restricted. While on the one hand its constituents are not all very closely related, on the other hand 
it almost intergrades with Euloxia, and in Africa perhaps with Acollesis or Nothoterfna. 
Type of the genus : Hemistola rubrimargo, Warren (1893). 
Geographical distribution of species. — Palcearctic and ;Ethiopian Regions, India to 
Formosa. 
SEcTION I. — Palpus moderate (occasionally even elongate in Q); hindwing angled ; 
antenna in 9 bipectinate (/7emistola, Warren).

1) Leech's Chang-Yang Q cannot belong to this species; it is evidently a Z7e»ifZca, related to s2775nearia.
