 Legs black, the anterior tiusi bright ferruginous, and their

 (Smith), but that insect has yellow mandibles, yellow 

 markings on thorax, &c.

 and closely punctured ; tegulse shining black, with few small 

 punctures. Wings very dark, reddish fuliginous,

Among the American species this is allied to O. azteca, 

 Cresson, which is smaller and has a yellow scopa. The 

 extraordinary thing is that O. erythrotricha looks exactly 

 like 0. pseudoauj'ulenta, Dours, which I have from Tangier. 

 I should hardly know how to separate them, but that the 

 African insect has red tegulse, a less hairy face, much less
