Acanthusus nivalis, sp. 0. 
Head and pronotum piceous, thickly greyishly pilose ; 
body beneath and legs piceous, lateral areas of sternum 
thickly greyishly tomentose ; a prominent greyish tomentose 
spot at each basal angle of scutellum ; tegmina bronzy, the 
apical area more distinctly so, the veins (excluding apical 
area) more or less distinctly greyish, base and costal area 
piceous and more or less greyishly pilose; pronotum 
strongly centrally carinate, the lateral processes well pro- 
duced, moderately flattened, broad at base but acutely 
narrowed at apices, outwardly not upwardly directed, the 
apices distinctly recurved, their anterior margins being thus 
moderately convex, the disk behind these processes gibbousty 
raised into a somewhat large compressed elevation, posterior 
process almost reaching tegminal apices, strongly tricarinate, 
concave near base and then convexly impinging on tegmina; 
ocelhi about as far apart from each other as from eyes. 
Long., incl. tegm., 34-4 mm. ; exp. lat. pronot. process. 
24-3 mm. 
Hab. Queensland ; Brisbane (H. Hacker); Kuranda 
(R. E. Turner). 
In fresh examples of this species the greyishly pilose 
appearance is probably very pronounced. 
Acanthusus festivus, sp. n. 
Pronotum and face reddish ochraceous, the posterior 
process from base to near apex pale stramineous, the central 
carination on frontal area and margins of lateral processes 
black ; femora dark castaneous, their apices and the tibiz 
and tarsi stramineous; tegmina bronzy brown, a costal spot 
before apex and a larger apical spot stramineous; pronotum 
anteriorly very strongly ceutrally carinate, the lateral pro- 
cesses outwardly triangularly produced, outwardly and 
apically very slightly upwardly directed, the disk behind 
these processes strongly gibbously upwardly produced and
