Show 1885.] MR. H. D R U C E O N N E W HETEROCERA. 519 dusky white scales : secondaries uniform dark brown, with two spots in the middle of the cell, and just beyond the end of the cell three small white dots ; the tips of the nerves along the outer margin from the apex to near the middle dusky white. The underside the same as above, but the spots are more distinct. Head, thorax, and abdomen brownish black ; legs black ; antennae wanting. Expanse 4 inches. Hab. N. India, Darjeeling. This species is allied to A. euplocoides and A. stelligera: from the former it is at once distinguished by the entire absence of the creamy white of the secondaries ; from the latter by wanting the marginal row of white spots to both wings and being without the blue marginal band.
