the following points : — Iti the male of St. hrvnnipes the width 

 of the iVont is narrower than in St. pratti, being only ^

 but in St. pratti they are greyish brown. The black stripes 

 on the thorax converge in front of the transverse suture, 

 whereas in the new species they are parallel. The cox?e,

In the female of Stomoxys hrunnipes the broad black stripes 

 on the thorax are nearly confluent. The abdomen is a shiny 

 black, and when viewed from behind spots become visible 

 on the second and third segments; in Stomoxys pratti the 

 abdomen is dark brown and when viewed from behind is 

 banded. Coxae, trochanters, and femora are black, whereas 

 in Stomoxys pratti they are light brown, except the last pair, 

 which are dark brown. 



It is also near Stomoxys tceniatus (Bigot, 1887, Bull. Soc, 

 Zool. Fr,), but Stomoxys tceniatus is much larger, being 

 7^ mm, in length. The front of the male of Stomoxys tcenia- 

 tus is wider tiian that of Stomoxys pratti, and the legs are all 

 a uniform pale yellow. 



The types have been presented to the Biitish Museum.
