320 Mr. A. G. Butler on the 
the costal margin, and the second near to the apex, 
where it bounds an elongated semi-pyriform costal spot, 
mottled with brown and edged below with whitish ; apex 
and a disco-cellular dot black ; one or two vague dusky 
spots on the disc; fringe tipped with dark brown ; 
secondaries with a discal indistinct bisinuated series of 
dusky spots; fringe tipped with red-brown; under 
surface bright ochreous, speckled and mottled with 
grey, excepting on the body and towards the base of 
secondaries ; wings crossed by a dark grey oblique 
stripe corresponding to the olivaceous line of the upper 
surface ; discal diffused spots not extending below the 
third median branch of the secondaries; primaries 
white, speckled with grey at apex; body paler than the 
wings; palpi reddish brown; expanse of wings, 1 inch 
5 lines.

9. Cratoptera primularis, n. 8. 
Nearly allied to C. vilaria of Herrich-Schiiffer, and to 
Drepanodes (!) pholata of Guenée; in shape it more 
nearly agrees with the former, but in markings (except- 
ing the absence of the subbasal line on the primaries) it 
is like the latter species; bright chrome-yellow; the 
wings crossed from apex of primaries to the middle of 
the abdominal margin of secondaries by an externally 
diffused bright red oblique line; this line is elbowed 
close to the apex of the primaries, and bounded externally 
by five small pure white spots upon the nervures ; fringe 
at apex black; wings below of a clearer yellow colour 
than above, and crossed by a rather broad oblique black 
band with reddish diffused edges ; external area sparsely 
speckled with black; primaries with four black dots in a 
zigzag series within the discoidal cell; body below 
whitish ; expanse of wings, 1 inch 1 line. 
Rio Jutahi, 5th February, 1875. Taken at light. 
There can be no question that this is congeneric with 
C. vilaria, and it is hardly possible that the Drepanodes 
pholata of Guenée, which has almost the same pattern 
on both surfaces (a pattern, moreover, which on the 
under surface is singularly striking) can belong to a 
different genus. I am therefore unwillingly compelled 
to believe that here, as in several other instances, this
