40 STUDIES IN AMERICAN EPHYDRIDAE (dIPTERA) 
cern and always require high magnification. The femoral cili- 
ation, although also apparent in the npana-group, is much more 
developed here, while the tibial ciliation is not at all developed 
in that group. The fifth segment of the male abdomen is dif- 
ferentiated, triangular, and convex apically. 
I have examined specimens of the European cinerea Fallen, 
and have taken that species as the type of this group. Cinerea 
is also the type species of the genus.

I place this species here, next to erythrocera, on account of the 
apparent intergradation of the two. In this group it is rather 
isolated by its vittate mesonotum, yellow antennal joint and 
quadriseriated abdominal design. On the other hand it is very 
distinct from erythrocera, and in general easy to distinguish, 
although the vittate individuals of that species are often con- 
fusing. The females may be difficult to separate from those of 
the recessive forms of facialis. 
I have examined the type of this species. 
Description. — Black; antennae except apex of third, and rarely the second, 
joint, palpi, halteres, knees, bases of fore tibiae and of their tarsi, middle and 
hind tibiae and their tarsi, yellow or tawny; tarsal fascicle black; wings brown- 
ish hyahne with pale veins. 
Opaque; frons olivaceous to golden, with vittae and preocellar dash darker; 
face and cheeks light yellow, sericeous; occiput, pleura and femora gray. 
Mesonotum fight olivaceous to golden brown with five darker dorsal and a 
broad lateral, stripe; mesopleura with large brown spot; scutellum with two 
discal spots. Abdomen gray with four series of large brown, subopaque spots, 
more or less coalescing on bases of segments; marginal bristles with basal 
brown dots; ventral lobes spotted. 
Frons quadrate; orbits parallel. Face three-fourths as broad as vertex, 
slightly longer than broad, with two or three distinct bristles on lower fourth 
of profile; in profile, vertical, slightly visible above. Cheeks as broad as 
length of third antennal joint. Antennal spine minute; third joint slightly 
conical, rounded apicaUy; arista with about nine hairs. Scutellum fiat, trape- 
zoidal, shghtly rounded apically. Abdomen ovate, rather long; segments 
subequal; fifth convex, triangular. Middle femora and tibiae of male strongly 
cihate. Wings long; second costal section twice as long as third. Length. — 
3 to 4 mm.
