bristles closer to the median ones than to the eye-margin; two upper 
rows of four equidistant ones each. Space about ocelli blackened. An- 
tennæ small, rounded, arista nearly bare, black except at base. Palpi 
small, bristly only at the tips, the bristles rather weak. Proboscis stout, 
porrect and very heavily chitinized, but slender and not enlarged at 
the tip. Cheeks bare except for two strong macrochætæ. Postocular 
cilia strong except near the ocelli. Dorsum of thorax sub-shining, 
yellowish-brown anteriorly, shading to piceous behind and on the scu- 
tellum which is about four times as wide as long. A single pair of 
dorsocentral bristles and two marginal scutellar bristles. Abdomen opa¬ 
que, without bristles or hairs. Pleuræ pale yellow, without spots and 
entirely bare. Legs moderately slender, front tibiæ with a series of four 
nearly equidistant small bristles along the outer edge, middle ones 
with a pair at the basal third on the outer side and a single one just 
before the tip; posterior pair with a series of five or six bristles on 
the posterior edge; posterior metatarsus two-thirds as long as the tibia 
and bristly below, not broadened. Wings hyaline, with a slight yello¬ 
wish tinge, veins testaceous except the costal which is piceous. Costa 
extending far beyond the middle of the wing, its bristles extremely fine 
and short but thickly placed. Mediastinal vein entirely wanting, and 
humeral cross-vein very weak. First vein ending two-thirds of the way 
from the humeral cross-vein to the tip of the third vein, the furcation 
of the third vein very oblique, the branches nearly parallel and mee¬ 
ting the costa very close together; fourth vein weakly and evenly cur¬ 
ved, fifth almost straight, ending nearer to the wing tip than the 
fourth; sixth nearly straight; seventh weak but distinct, much curved 
and close to the wing margin. Halteres pale clear yellow. 
Two females, Paraguay: Asuncion (Yezényi 1905, and Anisits 1904, 
IX—X.). 
On account of its elongated proboscis, the series of four bristles 
on the fore tibiæ, and the similar series of six on the hind tibiæ, this 
species comes in the group Dorniphora Dahl, which also includes 
Ph. papuana Brues, Ph. incisuralis Loew, Ph. Dohrnii Dahl, Ph. 
divaricata Aldrich and Ph. perplexa Brues. From the first it may be 
distinguished by the series of five bristles on the hind tibiæ, from the 
second by the fact that these bristles are placed along the outer 
edge. In Ph. incisuralis they are on the side near the inner edge; in 
the other three species the tibiæ are bare,
