 of generation scarcely differ from those of Melolontha. 



DicRANiA, Lepel. and Serv. 



Have two hooks, all equal and bifid, to all the tarsi, the an- 

 terior two of which have their first articulation prolonged 

 inferiorly into a crooked tooth. The body is very smooth, 

 without scales, with the scutellum tolerably large, and two 

 strong spines at the extremity of the four hinder limbs.

 furnished with scales. The hood is almost square, or almost 

 semi-circular. The thighs of the two posterior feet are mo- 

 derately inflated, and their legs are long, straight, and with- 

 out a hooked tooth at their extremity. 



There is very commonly found in the South of France, 

 near the borders of streams and rivers, the handsomest known 

 species of this sub-genus (H. formosa^ mig'» Melolontha 

 farinosa, Fab. Oliv., Col. I. 5, ii. 14, a. c). Its antenna; 

 have nine articulations. All its body is covered with brilliant 

 silvery scales, the upper ones of which have a reflection of 

 violet blue, and the lower ones are a little greenish or 

 golden.

The antennae of some others have ten articulations.
