Resembles &. Gilberti, from which it differs inter alia by the 

 red basal piece of the elytra not extending so far hindward and 

 having its hindmargin not (or only very narrowly) clothed with 

 dense pubescence, by the black apical piece of the elytra being 

 less evidently granulose, and by the subapical spot on each elytron 

 being (not an obliquely placed oval mark but) almost perfectly 

 circular. S. dispar, Kuwert, appears to be distinguished from 

 this species by the hinder part of the elytra being punctulate- 

 striate, and Victories, Kuwert, by the front part of the elytra 

 being black. The other described species seem to differ by 

 structural characters that may be regarded as subgeneric, espe- 

 cially by the shape of the joints of their antennae.

 I have no doubt that the specimen described above is a male. 

 It is easily recognizable by the remarkable shaggy and curled 

 pilosity on its head and prothorax. Each mass of hairs is about 

 as long as one of the antennae. The masses are placed one on 

 either side of the head running longitudinally, and one on either 

 side of the front margin of the prothorax running transversely. 

 The penultimate and antepenultimate ventral segments are 

 strongly and widely emarginate, so that their hind margins in 

 the middle are very close to each other and to the preceding seg- 

 ment, but much farther apart on the sides. The strong compres- 

 sion of the basal part of the hind tarsi and the denticulation of 

 the front (and perhaps also the intermediate) tibiae are also note- 

 worthy characters.
