450 A SECOND NOTE ON THE CARENIDES, 



/. Anterior tibisB bi- or tridentate ;* anterior 

 femora with a puncture near lower mar- 

 gin of inner side towards apex. Elytra 

 smooth (either quadri-, bi-, or impunctate) Carenum. 



g. Form elongate. Anterior tibise bidentate ; 

 anterior femora without a puncture near 

 lower margin of inner side towards apex. 



h. Antennae moniliform Neocarenum. 



hh. Antennse filiform Neosca'plius. 



aa. Lateral border of elytra narrow, and 

 neither reflexed nor thickened to form an 

 upturned projection at each shoulder. 



i. Labrum and clypeus emarginate Carenidium. 



a. Labrum and clypeus truncate Conopterum. 



AA. Anterior tibise with outer apical angle pro- 

 jecting strongly forward, the external 

 edge not dentate (unidentate). 



h. Front with a strong longitudinal sulcus on 



each side between the eyes Monocentritm. 



kh. Frontal sulci not extending backwards 



between the eyes Teratidium. f 



Genus Scaraphites. 



As a beginning towards tabulating the species of this genus I 

 offer the following syno[)tic list of the species now in my possession. 



* C. rectangula7'e, Macl., and C. tibiale, SI., have the anterior tibiae 

 pluridentate externally, but the teeth above the three large ones are in 

 reality merely strongly developed processes of the exterior ridge ; there 

 are indications of these more or less prominent in other species— e.^., 

 C. virescens, SI. 



+ In Teratidium the frontal sulci are weakly developed, and only show- 

 in that part of their course which turns obliquely outwards in front ; the 

 part behmd the anterior bend, which is so strongly marked in other 

 Carenides, being wanting.
