submarginal line is darker than the rest of 

 the wing. The margin is indicated by a 

 fine brown line, whicli is regularly crenulate, 

 returning inwardly at the middle of the 

 interspaces, the inward points being accentu- 

 ated by minute black spots. The fringes 

 beyond are uniformly pale brown. The 

 secondaries are marked like the primaries, 

 and have a lunate dlscal mark at the end of 

 the cell. The transverse line of the prim- 

 aries is continued across the secondaries to 

 the anal angle. The marginal markings are 

 the same as on the primaries. On the lower 

 side, both wings are pale argillaceous, pro- 

 fusely irrorated with minute brown scales, 

 except on the inner margins of the primaries, 

 which are whitish. There is a minute black 

 • spot in the middle of the cell of the prim- 

 aries, followed by a similar minute spot at 

 the end of the cell. There is no discal mark 

 on the secondaries. The outer margin is 

 indicated by minute black spots on the 

 middle of the interspaces.

 male, but the wings are broader and the 

 antennae are simple. Expanse, $ and J, 

 50 mm. 



This species is very distinct and may be 

 distinguished from the rest of the species of 

 this genus by the strongly angulated outer 

 margin of the primaries. The differences 

 between the various species hereinbefore 

 described are best recognized by an examina- 

 tion of the photographic representations given 

 in the plates. I have referred the foregoing 

 species to the genus Heterospila upon the 

 strength of a determination made by Mr. 

 Hampson of a specimen from Tenasserim, 

 which appears to be strictly cpngeneric with 

 the species described in this paper. Never- 

 theless, an examination of Guenee's descrip- 

 tion of his genus Heterospila apparently 

 reveals certain diacritic points, which 

 are lacking alike in the specimen determined 

 by Mr. Hampson and in the species under 

 consideration. The reference must, there- 

 fore, be accepted as simply provisional.

99. R. lampiima, sp. nov. ? . The 

 primaries and 'secondaries are acutely pro- 

 duced at the extremity of vein three. The 

 secondaries have the outer margin toothed 

 from the anal angle to the extremity of vein 

 three. The palpi and front are very pale 

 ferruginous. The upper side of the thorax is 

 reddish-fawn with an ochreous tuft of hair on 

 the metathorax. The upper side of the 

 abdomen is pale fawn. The lower side of 

 the thorax is whitish. The lower side of the 

 abdomen is pale fuscous tipped with white. 

 Tile primaries on the upper side are pale fer- 

 ruginous, shading on the outer third into 

 pale fawn. The wings are ornamented by a 

 series of exceedingly intricate spots and lines, 

 of which the marginal series are white and 

 translucent. There is a minute black dot in 

 the middle of the cell and a white semi- 

 translucent spot niargined with brown at the 

 end of the cell. There is a minute white 

 spot at the base; an irregularly curved and 

 angulated sub-basal line. From the lower 

 angle of the cell a brownish median line runs 

 to the inner margin. From the white spot 

 at the lower angle of the cell a transverse 

 series of semi-translucent whitish markings 

 slants outwardly to the inner margin, which 

 it touches about two-thirds of the distance 

 from the base. Beyond the end of the cell 

 are some pale ferruginous markings sur- 

 rounded by darker fawn; beyond these a 

 hastate translucent white spot with its apex 

 pointing toward the margin; and below it 

 two slightly curved similarly colored spots. 

 The submarginal series of translucent spots 

 describes an irregular curve from the apex to 

 the outer angle, the curved series being 

 convex inwardly, the third and sixth spots, 

 reckoned from the outer angle, being the 

 largest. The third spot is subhastate in form 

 with its apex, which is blunt, pointing 

 inwardly. Tlie sixth is subquadrate. Beyond
