Uah. — Queensland (Australian Museum). 
A very distinct species belonging to the succisus group. 
The (two) specimens under examination are probably partially 
abraded, but as the species is very distinct I have not hesi- 
tated to describe them. The seventh elytral interstice is 
moderately distinctly ridged in middle, so that it causes an 
appearance of a slight epipleural fold- Compared with succi- 
sus it differs in being considerably narrower, the elytra with 
less numerous tuberosities, the subapical tubercles larger and 
rounded and by the conjointly rounded apex. 
POROPTERUS LISTRODERES, n. Sp. 
Moderately densely clothed with stout brownish scales, 
prothorax with a very distinct complete border of paler 
scales, and which is continued on sides of elytra to apex, but 
decidedly incurved at basal third. 
Flattened, subelliptic. Head flat; ocular fovea indis- 
tinct : eyes finely faceted. Rostrum rather short and stout, 
increasing in width to apex ; muzzle moderately densely punc- 
tate. Funicle slightly longer than scape, second joint much 
longer than first- Frot liorax flat, sides moderately round, 
strongly narrowed towards apex, apex feebly bifurcate. 
Elytra not much wider than prothorax, and scarcely twice as 
long : base strongly bisinuate ; with series of large, shallow 
punctures, more regular on sides than on disc : the spaces 
between the punctures often tuberculiform, and with small, 
shining granules, second interstice near apex with a subconi- 
cal tubercle, apex itself without tubercles. Ahdomen with 
the third and fourth segments below level of second, but not 
of fifth. Legs moderately long : posterior femora extending 
to apex of elytra ; third tarsal joint moderately wide. Length. 
11 ; rostrum, 2J ; width, 5 mm. 
Hah. — Queensland : Mount Dryander (A- Simson). 
The very distinct pale lateral markings of the prothorax 
and elytra will readily distinguish this species : it belongs to 
the exitiosus groujD. The tubercles on the posterior declivity 
are rather small, and are indistinct when viewed from above, 
but they are very distinct from the sides. 
POROPTERUS LONGIPES, U. Sp. 
Moderately densely clothed with muddy-brown scales, in- 
terspersed (especially on legs) with rather long blackish setae 
and with stouter scales, on the elytra these form a feeble 
fascicle on each side at summit of posterior declivity. 
Strongly convex. Head with punctures concealed by 
clothing : ocular fovea moderately large ; eyes finely faceted- 
Rostrum long, thin, moderately strongly curved ; l3asal por- 
tion coarsely, elsewhere finely (very finely in female) punc-
