Classification of the Coleopterous family Dyiiastidie. 345 



front tibiae tridentate, the middle and hind tibiae truncate at the 

 end, but not dilated, and the tarsal joints equal and slender. 

 Mandibles very small, concealed by the clypeus, rounded at the 

 front and sides, and without teeth. Maxilke without teeth, the 

 terminal (outer) lobe blunt and ciliated. Mentuni long and taper- 

 ing, bidentate in front. Last joint of all the palpi long and slender. 

 Clypeus very short, with the front margin straight and retlexed. 

 Head and thorax entirely unarmed in both sexes. Prosternum with 

 a slender, sharply-pointed post-coxal process. 



^. The clyjjeus is a very little shorter, the front tibiae less 

 strongly toothed, all the tarsi much longer and the abdomen reduced 

 and contracted. 



The National collection possesses a number of males 

 belonging to three species, but only a single female, 

 Avhich sex is evidently much rarer than the other. It 

 is an interesting and isolated genus, exhibiting several 

 features foreign to the Dynastidas in general. The elonga- 

 tion of the tarsi of the male in other genera is a con- 

 comitant of the fullest development of armature on head 

 and thorax, whereas genera in which such armature is 

 absent are usually characterised by the opposite condition 

 of contraction of the male tarsi.

There are two males and a female of this in the British 

 Museum. It is shining black with reddish-yellow legs
