1. Dasytes oneili. 



Dasytes oneili Pic, L'Echange, xxvii, p. 151 (1907). 



(^. Antennae short, very little longer than in $, the elytra narrower 

 than in that sex and subparallel in their basal third. 



Hab. S. Africa, Bulawayo {type of Pic ; Mus. Cape 

 Toivn), Salisbury, S. Rhodesia {Dr. Marshall : iv, 1896 ; 

 iv, 1906) ; Pretoria (//. P. Thomasset) and Sterkfontein, 

 Transvaal (L. M. Bucknill). 



Found in abundance by Dr. Marshall at Salisbury, on 

 heads of grass. This is one of four extremely closely allied 

 hairy African forms superficially resembling a small 

 Henicopus, and mainly distinguishable from the rest by its 

 rather strongly punctured elytra and shining surface. The 

 punctures on the prothorax are coarse and widely scattered. 

 The tibiae and tarsi, and the antennae in great part, are 

 testaceous in all these insects. 



2. Dasytes rhodesianus, n. sp. 



Moderately elongate, shining, clothed with fine cinereous pubes- 

 cence intermixed with long, erect, blackish bristly hairs; brassy- 

 black, the elytra with a greenish tinge, the antennae (except at the 

 tip), the femora in part, tibiae, and tarsi rufo-testaceous. Head 

 narrower than the prothorax, very sparsely, finely punctate, deeply
