Head with the fore-part and mandibles sloped forward ; the 

 front sub-vertical, raised between the antennre so as to form a 

 transverse ridge concave in the middle ; eyes moderate, finely 

 facetted and very deeply emarginate ; gense long and rather 

 prominent ; palpi subecjual. Antenna; much longer than the body 

 in the S , a little longer or shorter than the body in the $ ; first 

 joint clavately thickened towards apex ; third equal to or longer 

 than the fourth ; fifth to tenth sulaequal or successively and very 

 slightly shorter iu length ; third to fifth thickened and spiued at 

 the apex, and sometimes, -with one or more of the succeeding 

 joints, fuMiished with a dense tuft of hairs at the apex. Prothorax 

 transverse, rounded or protuberant at the sides. Elytra long, 

 rounded at the apex. Legs moderately long; femora more or less 

 thickened at, or below, the middle, the hind pair not reaching to 

 the apex of the elytra ; first joint of hind tarsus as long as the next 

 two joints united. Front coxse strongly angulated outwards ; 

 acetabula widely open posteriorly ; intercoxal process raised and 

 rather narrow in the middle, shortly deflexed posteriorly. Meso-

The bodv is densely covered with pubescence, with a charac- 

 teristic colour in each of the two sections of the genus. One of 

 these sections corresponds to the genus Rosalia of IServille and 

 Lacordaire, the other to the genus Eurybatus of Thomson.
