the preceding species, of the peculiar form that Dr. Chapuis 
attributes to Chirida. That learned author says that the 
structure is not quite that which the term “ appendiculated ” indi- 
cates; but that the base of each claw is dilated in such fashion 
as to produce the appearance (if the two claws be looked at from 
in front of them) of their basal parts being connected by a kind 
of erect quadrate lamella. The front margin of the prothorax 
does not project far beyond the head ; when the antenne are pro- 
jected forward the apex of the basal joint is visible from above. 
N. Queensland ; near Cairns. 
C. (7) tacunata, sp. nov. Breviter late ovalis (vel potius sub- 
quadrata) ; nitida; sat convexa; supra rufo-ferruginea, 
margine explanato (prothoracis toto, elytrorum in medio 
solum) testaceo translucido; capite (parte antica nigra 
excepta) antennis (parte apicali vix infuscata) pedibusque 
testaceis ; corpore subtus nigro (abdominis apice testaceo) ; 
antennis elongatis ad coxas posticas attingentibus, articulo 
3° quam 2" graciliori et paullo longiori, 4° quam 3" sat 
longiori, 7’—11° clavam Jaxam minus dilatatam formanti-

levi (puncturis nonnullis sat magnis ante basin positis 
exceptis) ; elytris pone scutellum haud gibbis, vix striatis, 
strlis sat regulariter punctulatis (puncturis in stris sat 
parvis), humeris sat callosis, angulis humeralibus rotundatis 
minus productis ; corpore subtus sparsim perspicue punct- 
ulato; tarsorum articulo apicali ultra precedentem vix 
excedenti; unguiculis appendiculatis (in sensu solito). 
Long., 23 1.; lat., 2.1. 
The claws of this species are very difficult to examine without 
breaking them off as they scarcely project from the penultimate 
tarsal joint and are recurved in form so as to be closely applied 
to its under surface. They are divergent (7.e. having their dorsal 
border lying in the direction,—or nearly so,—of the longitudinal 
line of the tarsus) and are appendiculate in the ordinary sense of 
the term, the front claws being more markedly so than the others 
(perhaps in one sex only). This species is difficult to place in 
Dr. Chapuis’ classification of the Cassidide ; the only subfamily 
characterised as having the head covered by the prothorax and 
also the claws appendiculate is the Chiridites,—but in its single 
genus (Chirida) the appendiculation of the claws is of the 
peculiar structure mentioned above (under C. maxima), whereas 
in the present insect it is of ordinary structure. [t would perhaps 
be justifiable on this ground to find a new generic name for this 
species, but for reasons mentioned above it seems at present de- 
sirable to avoid multiplications of genera for the Australian
