JOHN D. TOTHILL. 



Described from six males collected in India by Dr. A. D. Imms as follows : — 



Binsar, Kumaon : 1 $, 25. v. 12, in jungle at 7,700 ft. 



Airadeo, Kumaon: 4 $$, 31. v. 12, 6,880 ft. ; 1& 3.vi.l2, 6,880 ft. 



This very large fly looks much like its Palearctic congener, S. ursina, Meig., and 

 is evidently closely related to it. The width of the front is however nearly twice 

 as great in the male of ursinoidea as in that of ursina. In the Indian fly moreover 

 the third segment of the antenna in the male is much broader than in the male of 

 ursina. 



Gonia himalensis, sp. n. 



The entire fly covered with pale golden pollinosity. Abdomen black, with yellow- 

 ish red on sides of each segment and rendered sub-opaque on account of the pale 

 golden pollen. Wings hyaline. Frontal vitta opaque, yellow. Third antennal 

 segment in female three times, in male six times, as long as second. Second segment 

 of arista only half as long as third. 



Fig. 7. Head of Gonia himalensis, sp. n,, £. 



Head (fig. 7) at vibrissae a little shorter than at base of antennae. Vibrissae 

 plainly above the oral margin. Palpi well developed, pale yellow. Eyes bare. 

 Cheeks (genae) pale golden pollinose and covered on their basal three-fourths with 

 golden hairs ; a row of black bristles along the oral margin and ending at the vibrissae'; 

 distance from the oral margin to base of eye about one-third the eye height. Sides 

 of face at narrowest part about as wide as distance between the two vibrissae ; pale 

 golden pollinose and covered with black hairs that at the lower end shade into the 

 golden hairs of the genae. Facial ridges bare, except on lowest sixth. Facial depres- 

 sion pale golden pollinose, with a well-marked vertical carina. First two segments 

 of antenna and sometimes base of third yellow ; third segment usually entirely
