Genera and S/>ecies o/"T;ibaiiitl<e. 25 



Madagascar : tyi)c ami three other specimens from Andra- 

 nohxva, Majunga Province, 20-29. xi. 1907 {J. J. Lloyd). 



In a note attached to the type the collector wrote : — 

 " The first specimen of this spicies that I have ever seen ; 

 taken while biting me on tlie hand ; bite not very severe/' 



Althongh agreeing with Clirijsops luadat/ascarciisis^ liicardo, 

 in the shape of tlie transverse band on the wing, C. lloydi 

 may at once be distinguished from the species in question, 

 as >vell as from its two new congeners described above, by 

 the ochraceous coloration of tlie first antennal joint. 



Table for the Determination of the Species of Chrysops 

 at present known to occur in Madagascar. 



1. AiiteuDse entirely black 2. 



Auteiinae not eutirely black ; tirst joint 



oclnaceous lloydi, Austen. 



2. Distal margin of dark transverse band 



on wing aiigulate or irregular 8. 



Distal margin of dark transverse band 

 on wing not angulate nor irregular, but 

 curved madayascaiensis, Ricardo. 



3. Basal cells in wing, witli exception of 



a small area near distal extremity 

 (larger in second than in first basal 

 cell), entirely filled with dark colour; 

 projecting angle on distal margin of 

 dark transverse baud on wing reach- 

 ing fork of third longitudinal vein ; 



legs entirely black visulensis, Austen. 



Basal cells in wing almost entirely 

 hyaline ; projecting angle on distal 

 margin of dark transverse baud on 

 wing not reaching fork of third longi- 

 tudinal vein ; legs not entirely black, 

 largely tawny ap-uyna, Austen. 



Genus Tabamus, Linn. 

 Tabanus kinyi, Austen, var. nigrifeminibus, var. n. 



? . — Length (5 specimens) 14 to 16*5 mm. ; wing-expanse 

 of largest specimen 29'4 mm. 



Di^'eriny from the tyjAcal form of the species chiefly in the 

 coloration of tlie frontal callus and of tJie middle and posterior 

 femora. 



Agreeing with typical form of Tubanus kinyi, Austen, as 

 described and figured (' Bulletin of Entomological Research,' 

 vol. i. pt. 4, pp. 291-293, figs. 1 & 2 a, January 1911), except 

 that: — frontal callus is mummy-brown or dark mummy-
