again as wide as long, its base not much wider than the front 
margin, all the angles are acute, the sides rather strongly rounded. 
The elytra! strife are scarcely impressed in front, but are very 
distinctly set with rather small punctures ; towards the apex both 
striae and punctures are subobsolete ; the interstices are quite 
devoid of puncturation. 
The eyes are large and less separated than usual in the genus, 
the interval between them being less than the length of their 
shortest diameter. The apical five joints of the antennae are more 
incrassated also than usual. The hind femora are not really 
dentate, but the attenuation of the apical portion is very sudden, 
so that the outline at this point is subangular. The hinder part 
of the head is a little tumid in appearance. 
This and several other species in my collection appear to me very 
doubtfully congeneric with typical Rhyparida , — but they are at 
least closely connected with insects that have been attributed to 
the genus (^R. minuta, Jac., e.g.), and present all the essential 
characters, — prothoracic episterna not convex, — postexfior four 
tibiae emarginate near external apex, and claws well developed 
and bifid. 
I obtained a single specimen on Eucalyptus at Leigh Ci’eek, 
about a hundred and fifty miles north of Port Augusta. 
The following tabxxlation of the species of Rhyparida described 
above will perhaps be useful : — 
A Hind femora unarmed. 
B. Sides of the px'othorax more or less rounded. 
C. Clypeus not separated from the front by a 
distinct furrow. 
D. Puncturation of prothorax not (or 
scarcely) defined. 
E. Elytra wholly testaceous; size small... piceilarsis. 
EE. Elytra wholly cyaneous or seneous. 
F. Prothorax and elytra uuicolorous... uniformis. 
FF. Piothorax red satelles.
