Show 1880.] LEPIDOPTERA FROM FORMOSA, 675 marginal line, fringe sordid white; secondaries silky white; thorax pale golden brown ; abdomen sordid silky white : under surface white, the primaries and body tinted with golden brown, Expanse of wings 1 inch. One specimen. Very much like Leucania inferens in colouring. 58. ALETIA FORMOSANA, sp. n. Primaries above pale reddish clay-colour mottled with grey, the apical third of costal border and a cuneiform subapical patch on the outer margin grey; reniform spot just visible as an indistinct B-shaped marking, the lower half filled with blackish scales; an angular discal series of seven black dots, the lower three forming an oblique line with the inner edge of the subapical cuneiform patch : secondaries opaline white with broad pale smoky-brown outer border, veins brownish: thorax pale clay-colour: abdomen pale brown, densely clothed with long white hair at the base. Under surface of the wings shining opaline white, the costal and apical areas tinted with brown and speckled with black : primaries with a nearly straight discal series of eight black dots on the veins, the first two confluent; a marginal series of very minute black dots : secondaries with a curved discal series of seven black dots on the veins, a marginal series of smaller black dots between the veins : body sordid, black-speckled. Expanse of wings 1 inch 5 lines. One specimen in fair condition. Resembles some of the Moths associated by Walker with Leucania extranea ; indeed it is possible that this genus may be represented in that series. 59. NONAGRIA GRACILIS, sp. n. Primaries pale golden brown, with slender darker marginal line and whitish fringe ; secondaries silky white, tinted with golden brown ; body pale golden brown, the thorax greyish, the abdomen whitish : primaries below paler than above, the internal area white; secondaries white, the veins slightly sordid ; body below pale sandy brown. Expanse of wings 10 lines. One male example. GLOTTULIDcE?1. 60. CHASMINA GLABRA. Chasmina glabra, Walker, Cat. Lep. Het. Suppl. ii. p. 636 (1865). Two females, undistinguishable from a female in the Museum from New Caledonia. XYLOPHASIIDcE. 61. SPODOPTERA ERICA, sp. n. Primaries above sericeous fuliginous brown, markings very indistinct ; a small blackish-edged white discoidal stigma; four or five 1 Walker places the genus Chasmina in this family with hesitation; in my opinion it is more nearly allied to the Acontiidse. |
