is distinctly acute in P. herbvji, a European species), and tlie 

 anterior cross-vein being situated before the tip ot the auxiliary 

 vein, a position which seems to be closely approached or equalled 

 in Plpiza noctiluca, L. My two s[)ecies have yellowish faces, though 

 in this genus the head has normally no pale markings. 



The ilies are small, blackish, shining, found in gardens and 

 amongst low bushes in sunshiny places ; and, as is the case in the 

 closely allied genera Pipiza and Paragns also, they are very 

 difficult to separate, even the European species in this group of 

 genera being very insufficiently known and overweighted with 

 synonymy. 



The two Indian species may be distinguished thus : — 



Legs principally yellow riifocincta, Bruii. 



Femora with basal half, or more, black . . riijiventris, Brun. 



30. Pipizella rufocincta, Brun. 



Piphella rufocincta, Brunetti, Rec. Ind. Mus. ii, p. 53 (1908). 



(S . Head: face yellowish-white with a narrow black line below 

 antenna}, which are blackish- brown : mouth and proboscis black; 

 vertex shining black, narrowing rather suddenly to the eyes, 

 which are contiguous for only a very short distance. Thorax 

 black, shining, with a slight aeneous tinge; a few white hairs on 

 the sides, in front of insertion of wings ; dorsum with short 

 greyish hair ; scutellum unicolorous with grey hair. Ahdomea 

 shining black, with very short pale pubescence, the whole 3rd 

 segment reddish-testaceous, and, in the type-specimen, extreme 

 tip of abdomen reddish. Legs yellowish-white; coxa?, a narrow 

 rincr at base of ajiterior femora, and the basal two-thirds of hind 

 femora, black. Winris quite clear. 



Length, G mm. 



Described from two S 6 taken by me at llaugoon, 23. xii. 1904 

 to 3. i. 1905 {type), and from one d" taken bv me at Umballa 

 (^\W. India, altitude 900 ft.), 8-13. v. 1905. 'in my collection. 

 Most species of Pi/iizella have unmarked abdomens, but this 

 species is certainly of this genus, and apparently \\idely distributed.

5 . Head : vertex a?neous-black, with violet reflections and black 

 hairs ; ocelli concolorous ; frons and upper part of antennal 

 prominence shining blue-black, with black hairs; abroad grey 

 dust band from eye to eye across middle of former ; tip of antennal 

 ])rominence, just between the antenna), pale. Anteniue black. 3nl 

 joint large and elongate; arista black. Face yellowish, with 

 whitish ])ubescence, a little darker about moutii-opening ; a black 

 narrow median stripe. Eyes brown, with short distinct grey 

 pubescence ; occiput black, with yellow hairs around margin. 

 T/torcM- Kneous-black, shining, with soft ytdlowish-grey pubescence.
