 The insect for which I propose this new generic name must, I 

 think, be referred to the Callidiopsides. It is very distinct by the 

 following characters in condnnation : eyes coarsely granulated, 

 basal 4 joints of the antenme together shorter than the 5tli and 

 6th together, head (at any rate in the male) much wider than the 

 prothorax, subvertical in front (as in BeUieliion). In some 

 respects, especially in the length of the antennae and the propor- 

 tion of their joints inter se and the general facies of the insect, 

 this species resembles Mecynoiius^ from which it may be at once 

 distinguished by its much more coarsely granulated eyes and 

 shorter hind femora ^^the latter when set back not leaching beyond 

 the base of the apical ventral segment).
