Allied to P. castor, but altogether paler : primaries testaceous ; 
two angulated bars across basal area, two or three indistinct spots in 
cell, an interrupted waved discal bar, a disco-subapical diffused 
spot, a litura running from costa to upper radial nervure, and a 
zigzag submarginal line, brown; a number of brown hatchings all 
over the wing, especially at outer margin: secondaries black-brown, 
costa pale shining testaceous; a broad disco-submarginal, slightly 
waved, dark testaceous band: body testaceous; thorax duller than 
abdomen, the latter with a double central longitudinal series of 
blackish dots, three basal segments with a lateral brown line: wings 
below stramineous ; markings nearly as in P. castor, brown; body

20. PERGESA GLORIOSA, N. sp. 
Somewhat resembles the C. elpenor group of Cherocampa: pri- 
maries red-brown ; the base, an irregular broad band across end of 
cell, increasing in width from internal nervure to costa, a narrow 
lunulated transverse discal line, the apical part of costal area, and a 
broad tapering irregular submarginal band bronzy olivaceous, dotted 
with whitish at the edges upon the nervures ; an interrupted pearly 
lilacine marginal line; fringe ochreous; a blackish spot on lower 
discocellular nervure ; secondaries dull olive-brown ; a broad rosy 
discal band, slightly tapering at both ends; outer margin reddish ; 
fringe ochreous, white at anal angle: body olivaceous, rosy at the 
sides: wings below bright rose-red, crossed by three continuous 
parallel greyish discal lines; primaries with costa ochreous, basal 
two fifths (excepting a subcostal dash extending into cell) dull 
brown, fringe ochreous ; secondaries with basal area creamy whitish, 
fringe as above; body bright rose-red, legs cream-coloured. Ex- 
panse of wings 3 inches 6 lines.

Genus Panacra, Walker. 
21. PANACRA ELLA, 0. Sp. 
Nearly allied to P. testacea, same general pattern and coloration 
above ; it differs as follows :—primaries more golden, with the trans- 
verse brown lines less distinct, postmedian transverse lilacine streak 
diffused and broader, a large quadrate area from external angle to 
end of cell suffused with brown; secondaries darker brown, pale 
discal streak less prominent and not so red in tint; body above 
duller: wings below altogether more dusky, disk redder, outer 
margin of all the wings distinctly dull brown ; transverse lines of 
secondaries better-defined ; body yellower in the centre and more 
greyish at the sides. Expanse of wings 2 inches 5 lines. 
Silhet. t Type, coll. F. Moore. 
Possibly an extreme variety of P. tes¢acea, but I think not.
