face but little prolonged, with a tuft of black hairs on 

 the nose; palpi yellow, darker towards the end. Collar 

 black ; on the thorax three broad , shining black , lon- 

 gitudinal bands , which are connected in the middle ; the 

 middle band not crossing the suture; the outward ones 

 shortened in front and prolonged behind as far as the 

 scutellum, which is also black; pleurae with a broad, 

 oblique , black band , reaching to the middle coxae ; meta- 

 notum black below. Abdomen slender at the base, a little 

 enlarged towards the end; hindborder of the five first 

 segments and the following segments entirely black; the 

 9 with the ovipositor as well as the small foregoing seg- 

 ment ferruginous. Legs yellow ; the tip of the femora and 

 tibiae, as well as the tarsi dark brown. Halteres yellow, 

 the tip of the knob blackish. Wings with a brownish 

 tinge ; veins black ; stigma fuscous ; furcated cell sessile (in 

 one of the female specimens shortly pedunculate).

 stein). 



This species seems to be related to P. laconica and or- 

 tiva Ost. Sack. (Berl. ent. Zeitschr. XXVI. p. 92 and 93); 

 it differs however in having the black markings less ex- 

 tended , especially on the abdomen , and from laconica by 

 the yellow metanotum , which has only a black spot on 

 the underside , and by the yellow coxae ; from ortiva in 

 having the black spot on the front absent.
