48 JOHN D. TOTHILL. 



with black hairs. Sides of face white pollinose, bare, nearly half as wide as the 

 facial depression. Facial ridges bristly on lower fifth. Facial depression white 

 pollinose without any carina. All segments of antenna black ; the third segment 

 in both sexes about one and one-half times length of second. Arista thickened on 

 basal two-fifths, the second segment as long as broad. The front as wide in female, 

 and three-fourths as wide in male, as either eye ;■ the sides of front white pollinose 

 above the antennae, blending to greenish on either side of the ocellar triangle ; 

 orbital bristles present in female and absent in male ; the frontal vitta dark brown, 

 opaque, and twice as wide as either side of front at narrowest place. Ocellar bristles 

 present in both sexes and directed forward. 



Thorax bright bluish green and very thinly white pollinose. Two sternopleural 

 bristles and four post-suturals. Scutellum bluish green, with three pairs of strong 

 marginal macrochaetae and a weaker terminal pair. Legs black ; in female, tarsi 

 slightly flattened out ; tarsal claws of male longer than in female ; middle tibiae 

 with several bristles on the front side near middle. The wings (fig. 2) brownish, 

 especially in the vicinity of the veins ; venation as in figure. R. 4+5 (third vein) 

 with about five little bristles at base. M. 1 +2 (fourth vein) destitute of an appendage. 

 Tegulae white. 



Fig. 2. Wing of OymnocJiaeta imrnsi, sp. n. 



Abdomen bluish green and shining ; the segments very thinly coated with whitish 

 pollen. The second and third segments with strong discal as well as marginal 

 bristles. The venter with a median longitudinal area bearing short, almost spinose 

 bristles. 



Described from one female (the type) and four male paratypes collected by Dr. 

 A. D. Imms, near Bhowali, Kumaon, India, in July 1909, at an elevation of 5,700 feet. 



This fine fly is about twice as large as 67. viridis, Meig., and easily separated from 

 it by the absence of an appendage at the bend of M. 1 +2 ; by its much more clouded 

 wings ; and by its bluish green rather than green colour. It is apparently more 

 closely related to Wiedemann's species rheimvardtii from Brazil than to any of its 

 Palearctic and Nearctic congeners. In the case of rheinwardtii, however, the palpi 

 are reddish yellow and the wings as clear as water. 



Serviliia transversa, sp. n. = 



Abdomen black, with the sides yellowish red ; the bases of segments two, three 

 and four with a wide pale-coloured band contrasting strongly with the remainder 

 of the abdomen. Wings hyaline. Male with very weak or no ocellar bristles ;
