strongly tridentate. Hind tibia not digitated. Maxilla slender. 

 with a long brush of hairs at the end. 



The last ventral segment is punctured in the female and smooth 

 in the male, and the spurs of the hind tibia are shorter and 

 sharper in the latter. 



This genus formed the first section of Burmeister's genus 

 Gametis, but as that name was subsequently restricted by 

 Lacordaire to the second section, it has been necessary to devise 

 a new one for the present group. It is intermediate between the 

 large genera Ghjcyj^hcina and Protcetia, but had not the meso- 

 sternal process broadly dilated in front of the middle coxoe as in 

 both those genera. The general form and features are those of 

 Protcrtia, but the bilobed clypeus without a raised margin connects 

 it rather with Ghjciiphana. 



The species of this genus are very abundant where they occur, 

 and are remarkable for extreme variability of colour and pattern. 

 All of them are spotted with white in a similar manner, but the 

 ground-colour is extraordinarily inconstant.

The form is oval and convex and the upper surface devoid of 

 hairs or setae. The head is long and rugosely punctured and the 

 clypeus very sharply bidentate. The pronotum is strongly and not 

 densely punctured, with the sides angulated in the middle, the hind 

 angles traceable, and the base sharply excised before the scutellum. 

 Jlie sciUellum is triangular and moderately sharp at the apex.
