whitish, traversed by two dark brown parallel lines ; seconda- 
ries with a black undulated marginal line, fringe traversed by a 
slender, dusky line ; under surface greyish-brown ; basal three- 
fourth of the wings limited externally by a very irregular dark- 
brown line, followed by a white line ; discocellulars dark brown ; 
apical borders irrorated with white ; fringe whitish, spotted with 
brown. Expanse of wings, one inch two-tenths. It is easily 
recognised by its blackish grey colour and white markings. 
Coremia ypsilonaria, Guén.—Superior wings dull whitish flesh- 
coloured, or somewhat straw-coloured, but very pale ; markings 
wood-brown, consisting of a space near the base terminated by 
an oblique black line, and containing another black line, a median 
band constricted in its lower, open in the form of a Y in its 
upper portion, enclosing a little cellular dot placed between two 
black marks of which the external forms a xX with filled-in tri- 
angle; there is also a series of little nervural dots, and an 
oblique sub-apical streak surmounting a faint brownish border ; 
inferior wings slightly smoky, without markings; underside of 
all the wings more obscure, especially the first half, which is 
limited by a vague line ; inferior with a cellular point and two 
faint sub-terminal parallel lines, scarcely visible on the upper 
side. Abdomen marked with geminated black dots. Palpi pro- 
duced but incumbent. Antennz furnished with long pectina- 
tions in their basal three-fourths, but afterwards filiform. Ex- 
panse of wings one inch and a fifth. 
lCovemia semifissata, Walk.,(=Cid. delicatulata, Guén).—Rosy-cine- 
reous with brown markings. Base of superior wings enclosed 
by a curved black line. Outside this at some distance isa 
second black band forming an acute angle near the costa. 
Between the second band and the median belt are first a broad 
irregular brown band, then two waved light-brown lines. The 
centre of the median belt is ashy, contracted towards 
the hinder margin, and contains a black discal streak. This 
central area is bounded by bands of brown and _ black, shewing 
traces of waved black lines. Outside the median belt are three 
parallel light brown lines, the third sometimes running into the 
submarginal band. Submarginal band blackish-brown, irregular, 
bordered by a narrow line of the ground colour. The veins 
between the median belt and the margin are streaked with short 
black dashes, and in the central belt the main veins are lined . 
with whitish grey. A light triangular patch at the apex. A 
marginal line of short black dashes. Fringe silky, greyish- 
brown. Inferior wings testaceous, with more or less indications: 
of dark lines. Marginal dashes pale brown, with small brown 
patches inside them. Fringe silky and brownish. Below testa- 
ceous. Forewings shewing the black discal streak, and outside 
this some faint brownish lines. Hindwings also have the black 
discal streak, and beyond it some five or six waved brownish 
lines. Marginal line absent, or very faint. Fringe paler than 
above. Expanse of wings about one inch and a fifth. 
It is very difficult to distinguish between this and Covemia
