462 A SECOND NOTE ON THE CARENIDES, 



The genus Careiuim, as recognised in this paper, contains, at 

 present, ninety-six described species ; these I hav^e endeavoured 

 to arrange in natural groups in the tabular list which follows. 

 The species are believed to be in their proper places according to 

 the system of classitication adopted ; those species, the position of 

 which I have felt unable to be confident about, are noted separately 

 after the table. 



Table grouinng the species of the genus Co,renuin. 



I. Suborbital channels to receive antennae straight, single, not 

 dividing the gense from the gulte. Penultimate joint of 

 labial palpi narrow, and evidently longer than last joint. 

 Anterior tibi?e tridentate (sometimes with some smaller teeth 

 above the three large ones) or bidentate, with some small teeth 

 above the two large ones. Inflexed margin of elytra wide 

 behind first ventral segment. 



A. Reflexed border of elytra extending past humeral angle on 



to base, narrowly reflexed and not forming a thickened 

 projection at shoulder. C. brevicolle group 



B. Reflexed border of elytra ending at humeral angle and 



forming a thickened upturned humeral projection. 



a. Elytra impunctate. 



b. Prothorax with posterior angles prominent and strongly 



marked ; the base almost truncate on each side behind 

 them, and with a short median lobe. Anterior tibiae 

 tridentate. C. transversicolle grouj). 



bb. Prothorax with posterior angles rounded ofi'. 



c. Prothorax with a well-marked basal lobe. Anterior tibia? 



tridentate. C. macleayi group. 



cc. Prothorax without any basal lobe. Anterior tibiae 



bidentate. C. IcHvijoenne group. 



aa. Elytra bipunctate. 



d. Anterior tibiae tridentate, with middle of lower side ele- 



vated into a serrate ridge (injerior ridge) extending 

 from near base to apex.
