Talle of Species. 



A. Elytra with eight large costiform interstices on each.

in a concavity at each posterior angle. 



c. Elytra with eighth interstice wide, its summit even in middle of 



length.

■ dd. Elytra with seventh interstice not interrupted. ...P. viridis, Gory. 



cc. Elytra with eighth interstice narrow, its summit crenulate or 



serrate *P. opacns, Gehin. 



BB. Prothorax with lateral basal impressions separated posteriorly from 



marginal channel by a convex space, 



E. Elytra with intercostal spaces sulciform, third, fifth, and seventh 



costa interrupted (catenulate) P. inacleayi, Casteln. 



EE. Elytra with intercostal spaces lightly raised and forming narrow 



ridges with a closely set row of punctures on each side (prothorax 



■ with sides 2-setose) P. brisbanensis, Casteln. 



AA. Elytra with fifteen narrow carinate interstices on each. 



F. Prothorax long (hardly broader than long), elytra with edge of reflexed 



border even iP. pradieri, Chaud. 



FF. Prothorax short, elytra with reflexed border bearing a few widely 



placed raised serrations. P. guerini, Gory. 



Pamborus alternans, Latreille.

P. elongatns Gory, Mag. Zool. 1836, p. 166. 



P. viridiaureus, MacL, Proc. Linn. Soc. N.S.W. 1893, viii. p. 409. 



Chaudoir (with Gory's type in his possession) united P. 

 elongatus with P. alternans. I place P. viridiaureus, Macl., under 

 P. alternans, for though it may be regarded as a subspecies, I 

 cannot differentiate it from P. alternans. Macleay seems to have 

 relied particularly on the elongate prothorax to characterise P. 



*ii"fl&.— Queensland: Cairns (Froggatt), Herbert River and Cairns (Dodd; 

 Coll. Sloane). I have identified P. opacns from Gehin's description. 



t Hah. — N.S.W. : Bellinger River ; one specimen given to me by Mr. W. 

 W. Froggatt. The exact habitat has not been previously recorded.
