CHRYSOMELIDA. 399 
forehead, two moderately wide stripes on prothorax (con- 
tinuous from apex to base), scutellum, a small oblique spot 
within each shoulder, a curved fascia at basal third of elytra 
(not quite continuous to extreme sides), three large spots 
beyond the middle (of which the median one is transversely 
suboblong), and two large subapical ones chocolate-brown. 
Under surface black, middle of sterna, sides of prosternum, 
two apical segments of abdomen, and three obscure spots on 
third testaceous; legs blackish, the claws red; six basal 
joints of antenne red at base, dark at apex; the others in- 
fuscate, apical third of the terminal joint whitish. 
Head with scattered minute punctures; clypeus truncate 
at apex, from each side a groove extending backwards to the 
eye, and close to each eye, surrounding a dark eye-like space. 
Antenne stout, the seven basal joints more or less sparsely, 
the others densely punctate. Prothorax more than twice as 
wide as long, sides slightly sinuous, base feebly bisinuate, 
anterior anglesrounded and produced, posterior rectangular ; 
each side at extreme base with elongate shallow punctures 
of fovee, elsewhere with very minute punctures and with 
small but deep scattered punctures almost absent on the 
sides. Hlytra at extreme base no wider than prothorax, and 
very little wider elsewhere; each with about ten seriate 
rows of small punctures, not traceable towards base or apex ; 
interstices not at all or scarcely visibly punctate. Length 
74, width 4mm. 
Hab.—Brisbane (types in Macleay Museum). 
A remarkable species, which I have hesitated to regard as 
belonging to Phyllocharis; but the claws are dentate, 
antenne moniliform and palpi ovate. The grooves on the 
head, with the truncate apex of the clypeus, and the dark 
isolated spaces at the sides, cause an appearance as if the 
head of a small Dytiscus or Cybister had been carved out, 
the resemblance being not traceable with difficulty, but 
absolutely perfect, and is as distinct in the variety (noticed 
below) as in the typical specimens. The wide prothorax 
and white termination of the antennz are also very distinc- 
tive features. The two brown stripes on the prothorax cause 
three testaceous stripes to appear, of which the median one 
is the narrowest; in conjunction with the scutellum, and 
the two basal spots of the elytra, they cause a W to appear 
when viewed from in front, or an M from behind. The 
basal fascia of the elytra may be considered as six closely 
conjoined spots. In one specimen the legs (except for the 
brownish femora) are testaceous, and the six basal joints of 
the antenne are entirely red.
