the cord; the third the wing apex; costal and subcostal cells brownish 

 yellow; a small brownish spot at the origin of the sector, sometimes 

 confluent with the basal crossband. Venation: almost exactly as in 

 P. ornatipennis (de Meij.); Sc short, Sci extending to about two-fifths 

 the length of Rs, Sc^ being proximad of the origin of the latter. 



Abdomen dark metallic blue; ovipositor yellowish com color, 

 the sternal valves darker; tergal valves strongly curved. 



Habitat: Japan : 



Holotype, 9 , Chichibu, Province Saitama, October, 1918

Edwards (Ann. Mag. Nat. Hist., ser. 8, vol. 17, p. 356; 

 vol. 18, p. 249; 1916) records this new species from Idzu, 

 Japan (June, 1910), but does not give it a name. P. flavitihia 

 is closest to P. ornatipennis (de Meij.) but is sufficiently dis- 

 tinguished by the broad complete basal wing band and the 

 different leg pattern. The brush of erect or nearly erect hairs 

 at the tips of the posterior tibiae is very conspicuous and sug- 

 gests the condition found in the recently described P. pennipes 

 (Brunetti) of India (Records Indian Mus., vol. 15, p. 308, 1918; 

 as gymnastes). This fly differs from flavitihia in the pattern 

 of the legs and wings.

Ormosia diversipes sp. n. 



Belongs to the nigripila group; general coloration black, including 

 the femora, the tibise and tarsi abruptly light yellow; wings gray, the 

 stigma brown, the costal margin with yellowish pubescence; anal veins

 abundant erect whitish pubescence that is little shorter than the length 

 of the segment that bears it. Head dark. 



Pronotal scutellum pale. Mesonotal praescutum blackish with 

 a heavy reddish brown pollen, the dorso-median area darker, producing 

 an indistinct stripe. Pleura shiny blackish; a brush of more than a 

 score of long erect yellowish hairs on the pleura between the bases of 

 the wings and halteres. Halteres light yellow. Legs with the coxse 

 dark brownish black, sparsely pruinose; trochanters dull yellowish 

 brown; femora black, a little lighter basally ; tibiae and metatarsi abruptly 

 light yellow, the tips narrowly darkened; remainder of the tarsi dark 

 brown. Wings gray, the stigma more brownish, the costal region
