Burmeistev in his description says that the elytra are concolorous. 

 In the two female examples which I have seen the black patches and 

 bands on the elytra are nearly obliterated. 



Sub-Family HOPLINIIN.E. 



Body partly or entirely clothed with scales, squamose hairs, 

 seldom with simple hairs ; labrum sub-horizontal or vertical, ligula 

 bi-lobate and projecting freely beyond the mentum {Pachycneniini) 

 or fused with the mentum {Hoi)liini), maxillae dentate or simple, 

 often with a broad membranaceous border; antennae nine- or ten- 

 jointed, club never very long, tri-jointed, the joints fitting against each 

 other ; elytra seldom convex, never covering the pygidium, which is 

 ■either vertical or strongly sloping in a forward direction ; abdomen 

 sometimes very compressed laterally; spiracles similar to those of the 

 Melolonthinje ; hind tibiae without spurs or with one spur only ; 

 claws single or double, unequal except in the genus DicJielus, cleft 

 or simple, the smaller one usually pressed against the larger which 

 is articulated as in the Sub-Family Eutelinm; ; hind femora without 

 oblique rows of bristles on the outer face. 



This Sub-Family can be divided into two distinct Tribes owing to 

 the shape of the ligula. 



Ligula free, membranaceous, bi-lobate Pachycnemixi. 



Ligula horny, fused with the mentum Hopliixi. 



The last-named Tribe can be also divided into three groups ownng 

 to the shape of the labrum and of the abdomen, or of both of them 

 combined. 



A'. Labrum not vertical. 



B"^. Abdomen very compressed laterally in the male. 



C. Anterior tibiae tri- or quadri-dentate outwardly, the 

 basal teeth set at right angles with the tibia, and the 

 apical tooth not oblique Hcteiochelith'n. 



A-. Labrum vertical or not. 



B". Abdomen compressed laterally in the male. 



C-. Anterior tibiae bi- or tri-dentate outwardly, the outer 

 teeth seldom set at right angles, and the apical one 

 always slanting ScelophijKidcit. 



A'. Labrum vertical or not. 



B". Abdomen not compressed laterally in the male. 



C. .\nterior tibiae with three slanting outer teeth Hoplides.
