Length : 24-24.5 mm. 



Described the above from three well preserved female-specimens, 

 taken by Prof. Matsumura at Maruyama near Sapporo, on the loth 

 of August in the year 1902. 



This species is somewhat allied to Tabanus bovinus^ Loew, from 

 Europe, but it is easily distinguished from that by the large dorsal 

 tooth of the third antennal joint, by the more greyish thorax, by the 

 longer and more tawny coloured abdomen which is covered with more 

 conspicuous golden yellow pubescence only leaving a median blackish 

 stripe, by the more yellow tinged wings, by the more abundant black 

 pubescence on the legs, and by many other points as described already ; 

 there is no allied species in our horse-flies. T. sapporoenus is a blood 

 sucker, biting cattle, but I have no other knowledge of its habits. 



I do not believe that this species I have now described is the 

 same as Prof. Matsumura has recorded as /". ntfidens, Bigot, but I 

 am convinced that it is a valid new species, for I have rather a long 

 series of the species quite agreeing Loew's description of nifidens, and 

 also I can not find that there is any allied species i:i th> worlJ.
