SOME NEW SPECIES OE TACHINIDAE FEOM INDIA. 53 



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

 Arista thickened on basal three-fourths, the second segment one-third to one-half 

 as long as the last. Front at narrowest point about one and one-fourth times in 

 male, and one and one-half times in female, as wide as either eye. Sides of front 

 at lower end opaque pale golden pollinose shading to shining yellow at the vertex. 

 The frontal vitta opaque, cinnamon colour ; at ocellar triangle only one-third as 

 wide as either side of front. Orbital bristles in both sexes. Ocellar bristles in both 

 sexes and directed backward. 



Thorax opaque, golden pollinose on a black base ; the scutellurn sub-shining and 

 yellowish ; long golden pile abundant on both thorax and scutellurn. Four sterno- 

 pleural bristles and four post-suturals. Legs black, varying occasionally to slightly 

 reddish in all segments ; tarsal claws and pulvilli only slightly larger in male than 

 in female. Wings (fig. 8) hyaline ; with two to six little bristles at base of R. 4+5 

 {third vein). 



Tegulae white. Abdomen subopaque pale golden pollinose on a black ground ; 

 the sides of all segments reddish yellow largely obscured in fresh specimens by the 

 golden pollen. Second segment with a pair of median marginal macrochaetae, but 

 no discals on segments two or three.

Described from seven males and nineteen females collected (except where other- 

 wise specified) by Dr. A. D. Imms in the United Provinces, India. The field data 

 are as follows : — 



Binsar, Kumaon : 1 <£ 2 ?$, 25. v. 12, in jungle, 7,700 ft. 



Bhowali, Kumaon : 1 $, 22.vi.12. 



DehraDun: 1 $, 22.iii.12, on grass; 1 $, 2. iv. 10 (Jasman) ; i $?, 2.iv.l3, 

 on grass; 1 $, 2.iv.l3 (N. C. Ckatterjee) ; 1 $, 7.iv.l3, on grass ; 3 ??, 9.iv.l3; 

 1 ?, 10.iv.13, on grass; 1 ?, 17.iv.13, on grass ; 1 ?, 22.iv.12; 1 $, 23.iv.12; 

 1 & 6.V.13; 2 <?<?, 17.V.13; 2 <?£, 22. v. 12; 1 ?, 30. v. 13; 1 $, 6.vi.l2. 



In size and general appearance this fly resembles both Nearctic and Palearctic 

 specimens of 67. capitata, DeGeer. The shortness of the second aristal segment 

 will however serve to separate it from this species, as also from 67. divisa, Meig., 

 67. fasciata, Meig., 67. ornata, Meig., and even 67. flaviceps, Zett. In fact in this 

 character alone the Indian species exhibits the condition found in Spallanzania ; 

 in habitus, however, the fly is clearly a Gonia. Macquart's species rufitibialis from 

 Pondicherry, and Walker's oestroides from Hindustan, I have not seen, and both 

 are unrecognisable from the descriptions.
