dot; longitudinal series of small roundish black spots, viz. 3-4 just 
beneath costal edge on basal third, a subcostal series of 7-8 from | 
to |, 5-6 beneath this from J to near apex, one at end of cell and 
6-10 in disc towards apex, a submedian series of 8-10, and sub¬ 
dorsal series of 7-9 : cilia whitish, base suffused grey. Hindwings 
rather dark grey; cilia grey, darker-suffused towards base.

Nearest polysticta Butl., but rather smaller, the spots larger and 
fewer, and distinct by dark cilia of hindwings and grey basal 
suffusion of cilia of forewings.

representing stigmata (plical obliquely before first discal, discal

Ethmia acontias Meyr. 
Described from 8 specimens from Ceylon. By an unnoticed 
misprint these are stated to be all <$ ; they are in fact all $ . Two 
examples from India (Dehra Dun, probably bred from Cynoglossum 
lanceolatum {J. C. M. Gardner), and Kanara) are <5 2 » these have 
the supramedian black streak of forewings prolonged by a series of 
three or four dashes nearly to apex, but are otherwise exactty 
similar, and I consider them only a geographical form, which (if a 
name is required) may be called tactogramma. The <$ has on upper 
surface of hindwings a yellowish hairpencil from base lying along 
costa to near middle, concealed beneath forewings. The species 
has also been bred from Ehretia. 
RHABDOCOSMA, n. g. 
Head smooth-scaled; ocelli posterior; tongue developed. An¬ 
tennae j;, d serrulate, pubescent, thickened with appressed scales 
towards base, scape moderate, with flap of dense scales beneath. 
Labial palpi moderate, straight, porrect, smooth, terminal joint as 
long as second, pointed. Maxillary palpi obsolete. Hind tibiae 
smooth. Forewings 2 from towards angle, 3 from angle, 7 to 
termen, 8-10 near together from end of cell, 11 from before middle.
