Male deep black, the last segment of the abdomen cinereous. Female 

 bluish-white ; antennae and tubercle of the vertex black ; mesonotum 

 with three deep black longitudinal bands, in front confluent, the lateral 

 ones shorter, behind pointed, and not reaching to the scutellum. Ab- 

 domen with the second and third segments deep black, the latter with a 

 bluish-white spot on each side ; the fourth and fifth at the base, the sixth 

 entirely deep black. Wings hyaline, veins blackish ; second branch of 

 the prasbrachial vein little abbreviated, the terminal portion of the 

 pobrachial and anal veins, respectively, only half the length of the 

 discal-transverse and the subanal veins, which they adjoin, so that the 

 discal and anal areolets approach the hind margin ; mediastinal areolet 

 faintly yellowish in the male. Halteres blackish in the male, in the 

 female dusky, with pale base. Legs dusky, in the female inclining to 

 testaceous, the base of the tibias paler ; tarsi dull yellowish at the 

 base, dusky towards the tip. 



Not common. May. In Mr. Halida/s collection. (I.) 

 According to Meigen's description of P. ornata (fcem.}, the 

 second branch of the pisebrachial vein is not abbreviated, and the 

 black markings of the abdomen are somewhat differently distri- 

 buted ; so that, with Zetterstedt, I hesitate to cite it, although 

 the agreement in the marking of the thorax seems to be complete.
