468 A SECOND NOTK ON THE CARENIDES, 



inferior ridge strongly serrate, extending along middle of lower 

 side of tibijB to apex ; apical ])late with a long acute tooth 

 projecting below tarsus ; intermediate tibiae with a very short 

 external tooth at apex. 



Length 25, breadth 975 mm. 



Hah. — NuUabar Plains, Eucla District. A single specimen in 

 the collection of C. French, Esq., Melbourne. 



An isolated species ; the short wide prothorax rounded on the 

 sides and almost truncate behind, and the broad rather depressed 

 elytra without discoidal punctures and with the lateral border 

 extending on the base past the humeral angle are noticeable 

 features that thoroughly separate it from all described species of 

 the genus. It is the only species of the genus Carenum known 

 to me in which the lateral border of the elytra is not thickened 

 to form an upturned projection at the shoulders. 



Carenum l^vipenne. 



C. l(Bvipenne, Macl., Trans. Ent. Soc. N.S.W. 1863, i. p. 59; 

 C. hevicoUe, SL, Proc. Linn. Soc. N.S.W. 1888, iii. (2), p. 1116. 



I am now able to compare the type of C. Icevicolle, SI., with a 

 specimen of C. Icevipemie, Macl., and can find no difFe'-ence 

 between them. It is impossible to think the locality given by me 

 for 0. Icevicolle, viz , Johnstone River, Queensland, can be a correct 

 one ; I received my specimen, as coming from the Johnstone 

 River, among a lot of other Coleoptera from diflferent parts of 

 Australia, but do not know the authority for the locality. 



It may be noted that in C. IcEvipenne, Macl., the supra-orbital 

 punctures of the head and the marginal punctures of the prothorax 

 are wanting; in C. ineditum, Macl., an allied species, a single supra- 

 orbital puncture is present, but there is no trace of any punctures 

 along the marginal channel of the prothorax. 



Carenum tibiale, n.sp. 



^. Robust ; prothorax widely margined, truncate on base, the 

 posterior angle sub-rectangular ; elytra bipunctate, convex, greatly
