Gen. DOLEROSERICA, n. gen. 



Mentum and buccal organs of the usual shape ; antennae 10- 

 jointed, antennal club 3 -jointed, very long in the male ; clypeus not 

 constricted laterally, but gradually narrowed from the base in the 

 manner of Autoserica, Neoserica, &c, separated from the head by a 

 frontal suture, and having no clypeal keel or suture, nor is the 

 anterior part depressed or excavated along the anterior margin ; eyes 

 strongly divided in the anterior part by the genal canthus which 

 projects very much, and having also a posterior keel situated higher 

 than the genal canthus and not connected with it ; body more or less 

 iridescent, often with a silky sheen, either short and convex, or sub- 

 elongated and only moderately convex, glabrous except for a few 

 setae near the anterior angle of the prothorax and along the marginal 

 fold of the elytra ; anterior tibiae bi-dentate outwardly ; hind coxae 

 short, very broadly dilated inwardly, and with two sets of diverging 

 bristles on the upper margin ; hind tibiae either broadly ampliated 

 inwardly or not ; anterior tarsi somewhat short, posterior fairly long, 

 hind spurs longer than the basal joint which is not longer than the 

 second, claws slender, very little divaricating, cleft underneath, but 

 with the upper tooth not abruptly curved ; coxae very broad, their 

 apical margin quite straight ; trochanters of anterior legs not broadly 

 dilated.
