Ocyptera dosiades, Walk. List Dipt. Brit. Mus. iv. p. 695°. 
Ocyptera soror, Bigot, antea, p. 5° (nec Wiedem.). 
To the localities given, add :—Nortu America, Nova Scotia 1.—Mexico, Rio Papagaio, 
Chilpancingo, Amula, Xucumanatlan, and Omilteme in Guerrero, Atoyac in Vera Cruz 
(Hf. H. Smith). 
Several more specimens of this species, which I formerly referred to O. soror, Big., 
have been received from Mexico. These agree better with Walker’s description of 
QO. dosiades, while the rufous coloration on the sides of the abdomen is. much more 
extended. In several males the abdomen may be described as rufous, with the base, 
an uninterrupted dorsal stripe, and the last two segments black.
