Some of the specimens have the face brown, which, as Ron- 

 dani himself points out, is the only difierence between his och- 

 rifacies and riolacra R. D. That the names are synonymous there 

 can consequently be no doubt. Desvoidy's name has priority, 

 but the name "violacea" was already occupied for Fabricius's 

 species, which belongs to this genus, and therefore Rondani's 

 name must stand. 



Schiner's description applies perfectly. I have specimens of 

 the same species from the European dealers, Staudinger and 

 Bang-Haas, labeled Pijrelh'a orh ricornis Wied. Brauer and Ber- 

 genstamm include 3fii8ca ochricornis Wied. in the genus Lucilia. 

 and as they had access to the type their opinion must be accepted. 



The ground color of the epistoma, vibrissal ridge,, transverse 

 impression and gena is a yellowish red of varying shade, and 

 all these parts, with appropriate incidence of light, appear more 

 or less thickly yellowish pollinose. The cephalic fourth, third, 

 half or even more of the bucca has the same ground color ; the 

 rest of it is black or brown, and the whole, with appropriate in- 

 cidence of light, looks thinly white pollinose. 



The dorso-ventral diameter of the bucca is 0.4 mm. ; of the 

 head, 2.1 mm. The bucca is rather thickly beset with black 

 hairs, which are larger towards the occiput, and at the edge of 

 the mouth opening assume the form of rather delicate bristles. 

 The vibrissal ridge has ventrad the principal vibrissa several 

 smaller vibrissa^, and dorsad the principal vibrissa one small 

 vibrissa, while the whole lateral surface of the ridge is beset 

 with very minute bristles. Gena naked. 



The front of the male is narrow on the middle third, but even 

 here the geno-vertical plates show distinctly as narrow pollinose 

 lines, and the series of transfrontal bristles is not interrupted 

 as it is in M. Jnpuncto. Dorsad the narrow part the front 

 widens to the vertex, ventrad it widens to the antennal inser- 

 tion. The geno-vertical plate is pollinose on its ventral two- 

 thirds and black but not polished on its dorsal third. The 

 vertex is black or brown, not polished. The great ocellar bris-
