Expanse of wings 3 inches 7 lines. Queensland (Janson). Type, B.M. Genus PERGESA, Walker. 11. P E R G E S A AURIFERA, n. sp. Primaries olive-green, base transversely spotted with black; a violet-centred black spot at end of cell, and from it to inner margin a nebulous dusky bar; disk more or less clouded with reddish, crossed obliquely from costa to inner margin by three parallel rows of black spots; three large costal subapical black spots; outer margin pearly, irrorated with black; fringe dull ochraceous ; secondaries black-brown, costal area pale brown; an anal, submarginal, cuneiform, dull ochreous fasciole : body olive-green, head margined with whitish; pterygodes grey, black-bordered ; abdomen with two longitudinal series of black dots, a lateral golden-yellow streak from second segment, and a broad, undulated, golden-yellow lateral border, each undulation with a central black dot: wings below nearly as in P. castor, but the black lines and dots heavier. Expanse of wings 3 inches 5 lines. Sikkim (Whitely). Type, B.M. Var. Primaries and body clay-colour, with a slight greenish tinge. North India (Janson). B.M. Allied to P. castor, but differing (besides colour-characters) in the much more acute falcate form and greater width of the primaries. Genus CHCEROCAMPA, Duponchel. 12. CHCEROCAMPA MACROMERA, n. sp. Nearly allied to C. elpenor, but much larger, the primaries duller in colour, with the outer margin more broadly rosy lilacine; secondaries with more than half the wing rosy; body with the dorsal rosy line less defined ; wings below with the costal ochraceous border duller, much narrower, only clearly represented towards base; transverse band converted into two narrow parallel lines. Expanse of wings 3 inches 4 lines. Silhet (Macgillivray), North India (Stevens). Type, B.M. Noted by Mr. Walker as a variety of C. elpenor; I am satisfied, however (from the fact that the more nearly allied Japanese species is now proved by breeding to be distinct), that it is a different species. |
