170 DOLICHOPID^, 



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

 more numerous spines of the hind metatarsus. 



Not rare. _(E. S. I.) 



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

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

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

 and entirely black hind tarsi : while it dili'ers from the next by 

 the beardless hind thighs ; and from B. dladeuui, by the black 

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

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