HAMEOPIS, gen. nov. 



Apparently nearer to Zamacra than to any other Geometric! 

 genus, though differing entirely in neuration, in body clothing, in 

 character of legs and palpi. Wings broader, shorter, and utterly 

 dissimilar in character : primaries with veins 8 and 9 out of 7, 

 stalked ; 10 and 11 closely approximated, stalked at base : secondaries 

 with all the veins separate excepting 7 and 8, which coalesce close 

 to base, separating again before middle of cell ; veins 3 and 7 both 

 emitted from cell before the terminal angles. Antennae with long 

 straggling pectinations (as in Zamacra) to about four-fifths 

 of the distance from their base, terminal fifth serrated; palpi 

 small, porrected, smooth ; thorax coarsely scaled, but not hairy ; 

 frontal process prominent, subquadrate, with bare /^-shaped 

 ridge running between the antennae to back of head and deep 

 facial depression ; legs smooth ; hind tibiae with median spurs 

 emitted close behind the terminal pair. Type H. rudicornis. 



201. HAMEOPIS EUDICOENIS, sp. n. (Plate XXXII. fig. 13.) 



Wings above sericeous white ; primaries irregularly speckled all 

 over with grey and blackish, a mottled subbasal band angulated 

 at median vein, a reversed oblique costal spot just beyond middle, 

 an oblique discal band forked on costa, and a partial outer border of 

 the same colours, the blackish parts being costal : secondaries with 

 a few scattered dark grey dots chiefly on the veins, indicating a 

 discal transverse line ; an apical patch and some scattered clusters 

 of dots representing an external border. Head and thorax white, 

 the horny shovel-shaped process and forked dorsal ridge on the 

 head deep chestnut; shaft of antennae dark smoke-grey, white 

 barred with dark grey at base, pectinations pale brownish grey ; 

 thorax white, patagia alternately spotted and transversely barred 

 with black, metathorax similarly marked ; abdomen golden testa- 

 ceous, whitish at the sides and at anal extremity, with dorsal dusky 

 spots. Under surface white : wings paler in markings but 

 otherwise as above ; tibiae banded in front with grey, tarsi black 

 above. Expanse of wings 42 millim.

This is the first female I have seen of H. rubrifasciata ; the species 

 would seem to be rare, Mr. Cravvshay having only obtained two 

 males during his sojourn in Nyasaland.
