Melieria obscuricornis Lw. (Plate VI, Figs. 4, 5.) 
Ceroxys Loew, Mon. N. A. Dipt., III, 126, 1873. 
Melieria Coquillett, Journ. N. Y. Ent. Soc., VIII, 22, 1900. 
Seventeen %, six 9, Springfield, Idaho (Skinner). 
Two % and five 9 of this series agree well with the typical 
description of this species, excepting that the antennz are not 
brownish-black, but entirely rufous, infuscate sometimes at 
apex. The remaining sixteen approach ochricornis Lw. in hav- 
ing the costal spot above and that on the small cross vein more 
or less confluent, and the somewhat distinct marginal bands on 
the abdominal segments. On the other hand, the first, or basal 
wing-spot extends to the costa, showing a tendency towards 
similis Lw.; but this latter species seems very distinct in having 
the marginal bands of abdominal segments very wide and dis- 
tinct. 
The following is a typical description of these specimens, 
which I think well to give: 
Front translucent yellow, orbits, vertex, face, cheeks, and occiput, 
whitish-yellow pollinose; one or two pairs fronto-orbital bristles near 
vertex. Antenne rufous; third joint sometimes infuscate at apex; arista 
blackish. Fovez brown in the middle. Palpi yellow. Thorax and scu- 
tellum whitish-yellow pollinose, with black bristles. Halteres white. 
Abdomen widest at second segment, gradually tapering to the apex, 
more grayish; posterior margins of segments 2-4 sometimes narrowly 
brownish; fifth segment of @ widened somewhat for the broad ovi- 
positor, which is like colored, its first joint as long as the fourth and 
fifth segments together, gradually tapering to a truncate apex. All 
coxe yellow, whitish pollinose; femora and tibize rufous; tarsi more 
or less infuscate. Wings yellowish hyaline; veins yellow except at the 
spot; the design as figured in Loew’s Monographs, Vol. III, plate 
VIII, figure 20; but the first spot sometimes extends from the costa 
to the fifth vein; the second pair sometimes nearly confluent; and the 
apical cloud more or less confluent with the spot on the posterior cross 
vein.

No doubt these are this species, but I will give here a short 
description of them as follows:
