are much more broadly dilated in the female, in which sex the 

 transverse ciliated ridge is very plain on both the intermediate and 

 the posterior tibiae, and the apical spurs of the latter are blade-like 

 and conspicuously dilated; tarsi very little longer than the tibiae, the 

 joints of nearly equal length ; claws long, curved and having a sub- 

 vertical, slightly hooked tooth set in both sexes close to the basal 

 part which is not dilated, the inner tooth is longer than the outer. 



The female is of a much heavier build than the male, and the 

 elytra are considerably more convex and more broadly ampliated ; 

 the antennal club is thick, ovate, and the apical joint shorter than 

 any of the other four. 



There is considerable doubt as to the type of this genus as founded 

 by Hope ; the species which he mentions, i.e., Macrophylla longi- 

 comis, Hope, has not been described, and is not identical with 

 Melolontha longicornis, Fabr., the antennal club of which is only 

 tri-jointed.
