 the antennae about four times the length of the second, tawny 

 at the base, the rest piceous. Palpi and epistome tawny, the 

 proboscis piceous. Thorax and scutellum black, a red spot

The eyes are distinctly hairy, more so than in the last 

 species. The second abdominal segment has a pair of mar- 

 ginal seta3 in the middle and a pair on each side ; the third 

 segment has a complete row of marginal setae. 



Genus Tachina, Meigen (1803). 



"Eyes bare or finely pubescent, rather widely separated 

 in both sexes, but nearer together in the males than in the 

 females. Forehead usually not very prominent ; facial angle 

 almost straight. Antennae nearly drooping, with the second 

 joint elongated, half, or rather more than half, as long as the 

 third joint ; arista bare, and usually thickened for half its 

 length. Facial ridges bare, or only ciliated along their lower 

 halves with short fine bristles ; cheeks bare ; fronto-orbital 

 setae usually extending half-way down the face. Abdomen 

 mostly conico-elliptical in the male, ovoid in the female, and 

 either with or without discal setae on the middle segments. 

 Wings with the fourth longitudinal vein usually bent at a 

 sharp angle, and often furnished with a spurious, or nearly 

 spurious, cubital appendix " (Meade).

 tomentum on each side bordering the eyes ; cheeks yellow ;

 dark-brown, the third orange. Thorax with grey tomentum 

 and four indistinct black bands ; scutellum greyish-black. 

 Abdomen dark-blue, metallic. Femora and tarsi black ; the 

 tibiae dark-brown, the knees tawny. Squamae white. Wings
