COSMIA, Ochs. 
Cosmia albipennis. (Plate CXXVII. fig. 13.) 
Nearest to C. trapezina : primaries with the same arrangement of lines, pale vinous 
brown^ the " orbicular " spot slightly paler^ oblique, slenderly outlined in dark brown, a 
similar spot between the latter and the base ; a small blackish aiinulus below the " orbicular 
spot ; outer half of the central belt darker brown, especially towards costa, including the 
reniform spot, which is outlined in blackish brown ; inner line of central belt oblique, slightly 
irregular, slender, but commencing in a black costal spot ; central line strongly defined, 
especially at costa, oblique, elbowed on interno-median interspace ; outer line strongly 
defined, subangulated ; an interrupted abbreviated black subbasal dash from costa almost to 
submedian vein ; a well-defined slightly undulated submarginal line, shaded internally with 
dark brown, from upper radial vein to costa ; the costal margin above this shade blackish 
brown, interrupted by three pale dots ; a slender blackish marginal line : secondaries of male 
creamy white, the fringe towards apex usually tinted with vinous brown, of female grey, witli 
pale fringe ; basicostal area silvery : body pale vinous brown ; abdomen of female grey, with 
vinous lateral and anal tufts. Under surface of wings creamy whitish, with the costal and 
apical areas more or less suffused with red ; the centre of the primaries, especially in the 
female, suffused with grey ; discoceliular dots and discal line much as in C. trapezina : pectus 
and venter of female more or less red, venter of male whitish. Expanse of wings 37-38 
millim. 
Dharmsala ; at sugar : i-are. 
Although structurally a Cosmia, and not much unlike C. trapezina in pattern, the form 
of the wings in this species reminds one rather of Tceniocampa. The white secondaries of the 
male are characteristic, somewhat resembling T. miniosa.

DIANTH^CIA, Boisd. 
Dianthsecia nivescens, (Plate CXXVIII. fig. 2.) 
Closely allied to D. auroviridis, from which it may at once be distingished by the silvery- 
white instead of whitish lines on the primaries, the more oblique and white costal dashes, the 
pure white spots in place of the minute angular whitish dashes in the cell, the large diffused 
bluish-edged white spot immediately beyond the cell, a pure white triangular spot below the 
latter, a squamose white apical streak, and the white edges to the marginal black spots. On
