C. ruficeps, Iliger. 
Q. Lytta ruficeps, Il. (Wiedmann, Archiv. I. pt. 3, 
p. 140, 1800). 
$. Lytta plumicornis, Castelnau? (Hist. Nat. des In- 
sectes, II. p. 274, 1840). 
“ Atra unicolor, capite solo toto rufo, antennis totis nigris, 
elytris obtuse acuminatis.” 
?. Totally black, except the head which is reddish- 
yellow ; the clypeus is yellowish, with a transverse black 
band, the labrum has a notch in the front margin which 
is yellowish, the other parts of the mouth are more or 
less fuscous. The head is polished, sparingly but dis- 
tinctly punctured. The thorax is subquadrate, slightly 
broader in front than behind, abruptly contracted and 
rounded in front, the fore-part is slightly impressed on 
each side, the whole surface is thickly and distinctly 
punctured, the disc has a lightly impressed longitudinal 
line, which runs into a deep fovea at the posterior mar- 
gin. The elytra are parallel, not narrower at the base 
than at the apex, where they diverge, and are each 
rounded. The antenne are four-fifths the length of the 
elytra, filiform, the second joint two-thirds the length of 
the first, the third a little longer than the first, the 
fourth two-thirds the length of the third; the remaining 
joints gradually increasing in length, and tapering. Legs 
simple. Tarsi beneath, spongy, fuscous. The meta- 
sternum and abdomen clothed with short grey-black 
pubescence. 
The ¢ israther more slender than the ?; the antennz 
are longer (very nearly as long as the elytra) , the second 
to eighth joits furnished with long hair on the lower (or 
inner) side; the anterior tibie are furnished with long 
black hairs; the innerside of the femora and tibiw clothed 
with golden pubescence. 
Long. 64-104 lin. 
Hab.—Java, Borneo, Sumatra. Brit. Mus. 
Good specimens of this insect appear in some lights to 
have a reddish-brown pubescence, but a slight alteration 
of the position makes it appear greyish. 
The male agrees with Castelnau’s description of Lytta 
plumicornis from China, and in the national collection 
there is a specimen labelled ‘ North China’ which I can- 
not satisfactorily separate from the Javanese specimens.
