 Museum. 



This species resembles Tahanus guinecnsis, indicus, trilineatus, 

 lineola, occidentalis, trivittatus, dorsiger, quinquevittatus , costalis, 

 obsoletus, but appears to us distinct from all. Macq., Dipt, exot., 

 i (I), p. 127. 



From the above description I concluded the species was the 

 same as Tabanus striatus, Fabr,, but on seeing the type in the 

 Paris Museum I find it is not so, but is nearly- related to Tabanus 

 orientis, and fulvimedius, Walker, from which it seems only 

 distinguished by its smaller size, and the legs being wholly 

 yellow. 



The type is in a dirt}^ condition, labelled from Malabar. 

 Forehead broad, with the same shaped callus as in Tabanus 

 orientis, reddish brown, extending almost as a straight stripe to 

 the vertex. Palpi yellow, small and pointed. Thorax with grey 

 tomentum. Abdomen blackish with pale white-haired segmenta- 

 tions, red-yellow on the first two segments and on the sides of the 

 third; no stripes or spots now visible ; under side pale yellowish. 

 Wings clear, veins and stigma yellow. Length 12 mm. 



Comparing it with a specimen of Tabanus orientis from the Brit. 

 Mus. coll. it appeared similar allowing for denudation, with the 

 exception of the lighter coloured legs and smaller size, so that 

 for the present it seems best to keep it distinct from the Walker 

 species.
