Male (t>~pe) from Turkey in Asia (Loftus). 

 ♦ Three females from the same localit}- (co-types) are nearly 

 related to Tabanus cordiger, Mg., but belong to a distinct species ; 

 the^' differ in the following particulars : — 



Antennae wholly red, black at the apex. Forehead one- third 

 narrower anteriorh, about four times as long as it is broad, frontal 

 callus reddish brown. Coxae and femora reddish yellow, as are the 

 tibiae, only the anterior tibiae with a brown apex ; tarsi reddish 

 brown, all with white pubescence. The under side of abdomen has 

 no median black stripe. The species is much lighter in colour and 

 slighter in form than cordiger ; the four specimens vary in size from 

 12 — 14 mm. In the female the band under the eyes is narrow and 

 yellowish brown. In the male the black hairs on the hind part of 

 the head are not present ; the under side of the abdomen is reddish, 

 greyer at the apex. Ricardo, Ann. Mag. Nat. Hist. (7), xvi, p. 201.

From Schahrud, Turkestan. 



Near Tabanus bifarius, lyoew, but ornamented with four black 

 stripes on abdomen , and with the femora except the grey base easily 

 distinctly luteous, fore tibiae except the apices and the posterior 

 wholly, the posterior tarsi at base wholly luteous. Eyes with one 

 band. Forehead with two black spots. I.ength 5f — 6 lines. 

 Wings 5^ — 51^ lines. Loew, Zeitschr., etc., p. 414. 



There are examples of Tabanus bifarius, Loew, in the Brit. 

 Mus. coll. determined by Dr. Kertesz, from Greece and Hungary; 

 these (females) have the frontal callus square, yellow, not reaching 

 the eyes, the middle callus oblong, larger than the frontal callus, 

 black. The femora wholly blackish, the tibiae yellow, black at 

 apices, all tarsi blackish. 



Presumably Tabanus quadrifarius has likewise two calli on 

 forehead and probably belongs to the subgenus A ty lotus ; there is 

 one female from Bagdad in Brit. Mus. coll. which may possible- 

 be this species.

 shaped, black. First joint of antennae whitish, the second red,
