Type, M. obscurus, Dall. 



When revising Walker's species in 1899 I accepted that 

 M'riter's arrangement and labelling of his Ochlerus scaber at 

 its face value, although on founding my genus Hemingius on 

 that species 1 stated that the type did not agree with the 

 description. I wrote : " Walker, in his diagnosis of this 

 species, describes the sciitellum as ' more than half the length 

 of the abdomen,' whereas it reaches the apex of the abdomen 

 &c." On further consideration I think it certain that 

 Walker misplaced the labels, for Stal saw Dallas's type before 

 Walker commenced his Catalogue, and I therefore sink my 

 genus and follow Stal's determination.
