tawny ; still differing from D. griseipennis, fcem., by the colour 

 more numerous spines of the hind metatarsus.

Obs. D. nitidiis, Mg v which came to him from England, is re- 

 ferred by Stannius to his J). nitens, a species which has black 

 antennse with only the underside of the first joint dull yellowish, 

 and entirely black hind tarsi : while it differs from the next by 

 the beardless hind thighs ; and from D. diadema, by the black 

 fringe of the alulae and the yellowish face of the male, as well as 

 by the colour of the antennse. I know none such.
