the prothorax and more ampliated laterally ; they are entirely covered 

 with yellow or flavescent scales according to the sex, and are almost 

 hairless even along the suture and the outer margins ; the pygidium 

 is covered with yellow scales, turning to white on the abdomen ; and 

 the pectus is clothed with white hairs.

Mentum very elongate, sub-parallel, or elongato-ovate for more 

 than half the length, then much narrowed, parallel, rounded at tip, 

 more or less sharply carinate in the middle of the outer face, ligula 

 divided into two parallel long membranaceous narrow lobes, labial 

 palpi inserted in two broad but nearly contiguous cavities divided 

 only by a narrow intei'val, the basal joint is short, the second is 

 slightly longer, the third is a little longer than these two put together, 

 and is sub-cylindrical and moderately blunt at tip ; maxillae very long 

 and slender, upper lobe narrowly horny outwardly, very long, and 

 fringed inwardly and on the upper side with a very thick, somewhat 

 long fulvous pubescence ; maxillary palpi moderately long, apical 

 joint shaped like the labial one, but longer ; head carinate laterally, 

 cl}"peus as long as the head, nearl}' sub-parallel, deeply eniarginate 

 in the centre at tip, and slightly grooved longitudinally in the median 

 part ; antennae ten-jointed, club as long as all the other joints ; 

 prothorax attenuate laterally in front and with the base arcuate ; 

 scutelluni triangular and as broad as long ; elytra sub-parallel, not 

 covering the whole of the propygidium, pygidium vertical and 

 somewhat convex in the male, more sharply triangular and sloping 

 in the female ; anterior tibiae with an inner slender spui", tri-dentate 

 outwardly with the apical teeth curved and the basal one much 

 smaller than the intermediate and nearly obsolete ; hind legs 

 similar in both sexes, tarsi long, anterior and posterior tarsi with 

 a double unequal claw each branch of which is cleft at the tip, but 

 the inner one is stronger than the outer, posterior claw single and 

 simple. 



The insects included in this genus are very hairy and covered on 

 the upper side, abdomen, and legs with glittering scales more or 

 less densely set. They are very abundant at the beginning of the 

 spring, especially on heaths. Their habitat does not seem to extend 

 as far as Namaqualand, where the kindred flower beetles are so 

 numerous and varied, but thev are met with in the Karroo as far
