144, Hypopyra Martha, n. sp. 
Nearest to H. dulcina of Felder, but at once distinguishable 
by its shorter primaries, its paler and redder coloration above, 
the absence of the oblique streak from the apex of primaries, 
' the well-defined central belt formed by the central incurved 
grey line, and the series of black dots which in H. dulcina 
touch the pale undulated discal stripe, the latter placed near 
the submarginal line, which is strongly undulated; only two 
small black dots at the end of the cell; the transverse stripes 
of secondaries straight; body much as in H. dulcina, but the 
thorax darker and the collar redder. Under surface quite 
different, uniformly red, crossed by three equidistant dusky 
discal stripes; veins, base, and a submarginal series of <-like 
marks brownish. Expanse 3 inches 1 line.

Ophiuside. 
CHRYSORITHRUM, n. gen. 
Allied to Ophiusa (O. fulvotenia), but differing in having 
the terminal jointof the palpi twice the length, the tegule 
greatly developed laterally so as to form a roof-shaped crest 
over the back of the thorax, the secondaries without the angle 
at the end of the first median branch. Type ‘‘ Catocala amata”’ 
of Bremer. 
145. Chrysorithrum sericeum, n. sp. 
Smaller than C. amata; primaries shining slaty grey, all 
the markings black, and surrounded by a line of the ground- 
colour, followed by a black line; the angular subbasal band of 
C. amata replaced by a very irregular band, not reaching the 
inner margin, its outer and inferior borders forming three un- 
dulations, its inner edge >-shaped: secondaries fuliginous 
brown, the disk deepest in colour, a broad tapering ochreous 
band, not reaching the anal angle, and widest just beyond the 
cell: body dark slaty grey; back of head, collar, and tegule 
blackish. Under surtace fuliginous brown, outer border 
narrowly grey: primaries with a broad subbasal triangular 
patch, sordid ochreous; a slightly curved discal belt, tapering 
at each end and crossed by black nervures, pale stramineous : 
secondaries with the basal third greyish; a central oblique 
squamose stramineous streak; palpi, tarsi, and the upper 
surface of the coxe and femora of the anterior legs brown. 
Expanse 2 inches 4 lines.
