 species, apart from its general darker colour, is distinguished at once by the pattern of the 

 wing-markings, bv the uppiT half of the face being entirely black, and by the marking of the 

 front and hind tibia-, which consists of but a single broad white band near the base. In the

 of the face is stated to be black ; this species, however, has wing-markings of the 

 jnilr/irit/iortu- tvpe, and doubtless belongs to tlu' group, in spite of Loew's somewhat 

 misleading description iiml tiguic of tlic tliunicic stript'. 



Genus Tabanus, Linnieus 



Eight species of Seroot-flies belonging to this genus ai'c noticed below ; the Sudanese form 

 of one of them appears to constitute a new subspecies, whieli is here described. Specimens 

 of certain other species received during the past year were uufortuuately too much damageil 

 to be recognisable.

(N.U. — This synonymy is new.) 



Specimens of this species, with- 

 out indication of precise locality, 

 were received during the past year 

 from Dr. Balfour. Females of 7'<//'(»i»/.s- 

 /iiir, which vary in length from 'J'^ to 

 12g mm., are recognisable by their 

 yellow colour, small size, unifonnly 

 yellow legs, and clear wings with 

 yclldw veins. The dorsum of the 

 thorax is somewhat greyish yellow, 

 while the abdomen is tawny or 

 ochraceous ; the third joint of the 

 anteUHie is ochraceous-rufous ; the 

 front (space between the eyes) is 

 narrow. In life the eyes are green, 

 without transverse bands. 

 The ran';.' i.l T.i/mnns /„ir extends from Cape Ctdouy ami Xatal to Uganila and
