Helieria obscnricornis Lw. (Plate VI, Figs. 4, 5.) 



Ceroxys Loew, Mon. N. A. Dipt., Ill, 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 antennae 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 

 simiHs 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. Antennae rufous; third joint sometimes infuscate at apex; arista 

 blackish. Fovese 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 

 coxae yellow, whitish pollinose; femora and tibiae rufous; tarsi more 

 or less infuscate. Wings yellowish hyaline; veins yellow except at the 

 spot ; the design as figured in Loew's Monographs, Vol. Ill, 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 :
