of the Tabanus chrysurus. The chief difference is that the basal 

 joints of the antennae of the Tabanus chrysurus are covered with 

 short black hairs^ the frontal callus is oblong and stretches upwards 

 in the form of an elongated stripe ; the thighs are of a brownish 

 black, and the front tibiae blackish at the ends, the front metatarsus 

 brownish black, and the discal cell of the wings is longer than that 

 of large species of the European Tabanus. 



The basal joints of the antennae of Tabanus buddha are quite 

 bare ; the frontal callus of the forehead is quite round, and does 

 not extend upwards at all, all the legs are of a reddish yellow, only the 

 thighs at the base are yellow-brown, and the discal cell of the wings 

 does not dilfer from that of large species of our Tabanus." 



These small differences hardh' seem sufficient to keep Tabanus 

 buddha as a distinct species, the lighter colour of the femora may 

 perhaps allow it to be considered as the Chinese subform of Tabanus 

 chrysurus. 



Coquillet records seven specimens from Japan. In Brit. Mus. 

 coll. are females from Yokohama District (Prior), and Hakodate, 

 Japan (Fletcher) ; and in Kertesz coll. from Japan. 



The frontal callus is large, reddish brown, shining, club- 

 shaped, the linear extension usually short, rather stout, or nearly 

 non-existent. The forehead about five times as long as it is broad, 

 almost parallel. The legs in all of the specimens have the femora 

 black, reddish yellow at their apices, in some the apices of fore 

 tibiae are hardly darker, or very slightly so. lyength 25 — 30 mm. 



Atylotus pyrrhoceras was described from one female from 

 north of Yeso, Japan ; judging from the description it is probably 

 a denuded example of Tabanus chrysurus^ which is distantly related 

 to Tabanus barbarus, Coq., which occurs in S. Europe and N. Africa, 

 Ijut easily distinguished from it by the wholl}' yellow-haired abdo- 

 minal apex, by the yellow beard and darker femora. Tabanus 

 awnci«c/;/s,Macq.,Dipt.exot.,i (i),p. 134, pi. xvii, fig. 2, described 

 from the islands of the Indian Ocean, is apparently a synonym of 

 Tabanus barbarus, as given by Pandelle in Revue d'Entom., ii, p. 

 201, i (1883), the older specimen is recorded from South Europe 

 and N. Africa, and has therefore an extended range if ^Nlacquart's 

 locality is correct, which appears doubtful from the absence of any 

 specimens in the collections from the Oriental Region which I have 

 had access to (see ante, p. 491).

In Brit. Mus. coll. four temales and two headless specimens 

 from Japan (Dr. Miyajima, 1909). The subcallus is almost entirely 

 black, shining, perhaps from denudation as the insects suffered 

 much damage on the journey ; otherwise they are identical 

 with European specimens. This species has thus a very wide
