thickly punctate ; other structural characters as in generic 
diagnosis. 
Long., incl. tegm. and ant. pronot. process., 9 mm. 
Hab. New Guinea; Dory (A. R. Wallace). 
Centrotypus bowringi, sp. n. 
Head, pronotum, and body beneath black ; legs piceous ; 
abdomen beneath and sternum thickly, longly, ochraceously 
pilose ; tegmina shining castaneous, the costal area piceous ; 
pronotum coarsely punctate, centrally strongly medially 
carinate, the lateral processes moderately broad, upwardly 
recurved, their upper surfaces distinctly longitudinally 
carinate, their apices broadly subacute, seen from the front 
more straightly oblique and apically acute, posterior process 
strongly tricarinate, its apex reaching the posterior angle of 
inner tegminal margin. 
Long., incl. tegm., 7 mm.; exp. lat. pronot. process. 5 mm. 
Hab. Penang (J. C. Bowring). 
Allied to C. shelfordi, Dist., from Borneo, but differing in 
the shape and structure to the lateral pronotal processes, 
which are more slender and apically subacute than in that 
species. 
PoLonivs, gen. nov. 
General shape and form of the Australasian genus Ser- 
torius, but with the posterior pronotal process not promi- 
nently thickened at its base, and only about reaching the 
posterior angle of the inner tegminal margin ; apical areas 
to the tegmina longer and their veins more or less turned 
inwardly as in Pogon. 
Polonius liseratensis, sp. 0. 
Head and pronotum black, finely shortly pilose, the face 
and front of pronotum longly, thickly, ochraceously pilose ; 
legs castaneous, palely pilose ; scutellum with an apical spot ; 
tegmina castaneous, base and costal area black or piceous; pro- 
notum finely punctate, centrally longitudinally carinate, the 
lateral processes very short and recurved, their apices acute, 
posterior process strongly tricarinate, moderately slender, its 
base very slightly separated from scutellum, its apex acute 
and about reaching the posterior angle of the inner tegminal 
margin ; legs longly pilose.
