NEOTROPICAL STRATIOMYIDAE — JAMES 603 



orbits by a moderately deep groove; the occipital orbits moderately 

 rounded behind, front moderately convex, flattened above, and with- 

 out a median groove; the posterior part of the front somewhat de- 

 pressed, the ©cellar prominence rising from this depression ; the vertex 

 rising from this depression, at its greatest elevation approximately 

 level with the ocellar prominence. Pile of head white, inconspicuous 

 except on the sides of the face. Eyes bare. Antennae black, the first 

 two segments black-haired; the ninth segment twice as long as the 

 tenth. Proboscis and palpi black. Thorax metallic violet-blue; 

 scutellum and spines concolorous, the latter, however, tipped with 

 yellow, scutellum on a level with the dorsum; the spines directed 

 straight backward, slightly curved, about three-fourths the length 

 of the scutellum. Pile of thoracic dorsum black, inconspicuous, that 

 of pleura whitish. Wings deep black. Halteres black. Legs me- 

 tallic blue, the tarsi black; the middle basitarsi at most slightly 

 brownish basally; tarsi with dense, short, golden pile which may 

 make them appear yellow to the naked eye. Abdomen concolorous 

 with the thorax; pile inconspicuous, black dorsally, whitish on 

 venter. Length, 12 mm. 



Holotype. — Female, Bogota, Colombia (B. Gueyara). U. S. N. M. 

 No. 52762. 



Paratype. — Female, same data. 



CYPHOMYIA ALTIFRONS, new species 



Male. — Head yellow, the occiput black only in the middle. Eyes 

 separated at their nearest point by a distance equal approximately to 

 the width of the second antennal segment; the vertical triangle, in- 

 cluding the upper part of the front, enormous, inflated, greatly ele- 

 vated above the eyes and the occipital orbits; the latter well devel- 

 oped. The relative width of the vertex at its widest point, of the 

 front at its narrowest point, of the face above the oral margin, and 

 of the occipital orbits (average), 26:4:22:10. Pile of vertex and 

 occiput sparse, whitish ; that of face light yellow, conspicuous. Eyes 

 bare. Antennae black, the first and second segments black-pilose; 

 segments 2, 8, 9, and 10 subequal in length, the first twice as long as 

 the second. Thorax metallic violet-blue; pile black dorsally, whitish 

 on pleura, in one specimen with slight evidence of a median dorsal 

 golden band; scutellum and spines concolorous with the thorax, the 

 spines yellowish at their tips; pile black. Spines almost as long as 

 the scutellum. Legs metallic blue, the tarsi black; the middle and 

 sometimes the other basitarsi somewhat yellowish basally ; the basi- 

 tarsi with dense yellow pile, which may make them appear yellow to 

 the naked eye. Wings deep black. Abdomen concolorous with the 

 thorax, black-haired. Length, 11-12 mm.
