PLATYZOSTERIA (?) PICTA, spec. nov. ~ 
Reddish chestnut ; oval. Margin of clypeus, and the antenne 
beyond the first joint, yellow. Pronotum semicircular, angles 
obtuse, hindmargin slightly produced in the middle, finely 
impressed rugulose, with distant shallow pits and smooth spots of 
various forms; laterally a broad intramarginal yellow band, 
widely separate in front, cwrved inward behind but not attaining 
the hindmargin, and bordered exteriorly with brown, including 
the whole posterior angle. Meso- and metanotum similar, the 
broad oblique yellow bar terminating acutangularly inward ; 
hindangles slightly and obtusely produced. Elytra absent. Legs 
and underside of body color, coxz bordered yellow. Abdomen 
rugulose, with rows of coarsely-impressed pits, confluent on the 
posterior segments, each segment laterally with an oblique, sub- 
triangular bar, bordered brown (reproduced beneath as a small 
spot), and afew brown dots. Supra-anal lamina rugulose, arcuate, 
rounded, margin slightly serrulate, a triangular yellow spot on 
each side near the base. Cerci brown, acute, not exceeding the 
lamina. Apex pale. Collection 8.A. Museum.

Habitat.—Cooktown, North Queensland; Victoria (?) (pre- 
sented by C. French, Esq., F.L.S.). 
There are two specimens of females before me which agree in 
general aspect, but differ in some details, due probably to age. 
The pale band of the pronotum of the smaller one is contiguous 
in front, not widely separate, as in the other, and much more 
distant from the hindmargin ; the bands of the meso- and meta- 
notum, also of the abdomen, are very much smaller, the pale 
spots of the lamina wholly absent, and the cerci black. 
Altogether the aspect and markings of this species are so dif- 
ferent from its congeners that its place in this genus seems doubt- 
ful, and it might be assigned with almost equal reasons to 
Anamesia, Polyzosteria, or a separate subgenus, possessing inter- 
mediary affinities and differences. The present work is still of a 
preliminary character, and only when larger collections of species 
and individuals have been brought together and critically collated 
will any finality in arrangement be possible.

spots minute, antenne brown, basal part black, except first seg- 
ment. Pronotum semicircular, with a few impressed dots on the
