1904. } Catalogue of the Coleoptera of South Africa. 283 
long, moderately convex, bulging laterally in the median part and 
with both angles sharp; scutellum somewhat short, nearly semi- 
circular ; elytra elongated, covering the greater part of the long 
and broad propygidium, slightly ampliated laterally at about the 
median part, and having a long supra-marginal impression as a 
continuation of the humeral callus, the posterior calluses are very 
conspicuous ; pygidium strongly slanting ; abdominal segments fused 
but with the suture well-defined ; metasternum with a median longi- 
tudinal line and produced as a blunt triangle between the trochanters 
of the intermediate femora ; anterior tibie bi-dentate outwardly, and 
having a sharp, slender inner spur, intermediate and posterior ones 
with a very slight oblique keel, apical end of hind tibie very little 
dilated, spurs more slender and sharper at the tip in the female than 
in the male; tarsi slightly longer in the male in the anterior and 
intermediate legs, and shorter in the posterior, shorter in all the 
legs in the female; claws long, divaricating, angular underneath 
at the base, and with a sharp, vertical post-median tooth in both 
sexes, 
The species included in the genus are wholly covered with con- 
tiguous, lanceolate greyish-white, or sub-flavescent scales; some of 
them have one or more lateral rows of very distinct white scales, 
larger than those forming the vestiture. This character has been 
made use of for differentiating some species, but it seems to me to 
be somewhat variable. 
The genus is represented in Nyassaland; German East Africa ; 
Cameroon and Lower Congo. 
The South African species are captured from November till end 
of January.
