 on the fore border to the end of the first longitudinal vein.

Tabanus suhvittatus, $ , sp, n. 



Type (female) and two other females from Bihe, Angola, 

 Dec. 1903 {Wellmark), 1904. 243, in Brit. Mus. Coll. 



This species is very nearly related to Tabanus septem- 

 jnmctatus, ? _, Ricardo, but differs in the spots on the abdomen. 



The black spots of the fourtli segment are all included in 

 one black band, the spot on the second segment is more oblong 

 than square, and the pubescence of the posterior borders of 

 the segments on the underside is of a paler yellow. The 

 yellow pubescence of the posterior femora is more distinct 

 and in one of the specimens extends to the posterior libiaj. 

 The specimens are of smaller size, 18 mm. On two of them 

 is a note, " Cauglit near cattle."
