In the female of Stoino.vija In unnipes 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 Slomo.vys 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 than that of Stomoxys pratti, and the legs are all 

 a uniform pale yellow. 



The types have been presented to the British Museum.
