above. Wings hyaline or but faintly yellow- 
ish fumose. Smaller species, body length 
under 6.0 mm 3 
3. Only 3 spines on each front tibia, above 
the apical set (Fig. 2a ) . . . .harrisoni n. sp. 
Five spines present on front tibia, above 
the apical set; these are arranged in two 
groups (Fig. la) 4 
4. The two sets of spines located rather close 
together near the middle of the tibia (Fig. 
la). Apical spurs on the front tibiae much 
stronger than the spines (Fig. \a). Hind 
metatarsi of males not broader than apices 
of tibiae 5 
The two sets rather widely spaced, the first 
is at the basal third of the tibia and the 
second is near the apical two thirds (Fig. 
Gh). The apical spur about equal in size to 
the spines (Fig. Ga). The hind metatarsi of 
the males broader than the apices of the 
tibiae segnis (Hutton) 
5. Pile of body very dense and long, the hairs 
on the scutellum and in the dorsocentral 
areas of the mesonotum are about equal 
to one half the length of the halteres. 
, apical portion of front tibia (lateral aspect) ; c, ninth 
Wings slightly yellow fumose, posterior 
veins brownish. Radial vein setulose 
throughout its length. Tibiae of male 
yellowish colored, lighter than the femora. 
The spur at the apex of each front tibia 
about 1.5 times as long as the apical spines 
(Fig. ih) crinata Hardy 
Pile rather sparse and short, scarcely ex- 
tending higher than the spines of the an- 
terior row on the dorsum of the thorax. 
Wings hyaline, posterior veins colorless. 
Radial vein nearly bare. Legs of male 
entirely dark reddish brown to black. The | 
spur on the front tibia twice as long as |

This species is related to P. insolita (Hutton) 
but is distinguished by the characters given 
in the above key and by genital characters 
(cf. Figs. Ic, id, Ah, and Ac). The species has
