iQii.j O. RiCARDO : Revision of the species of Tabanus. 197 



states the legs are ochre-brown, and calls the thorax yellowish with 

 broad reddish brown stripes. It ma^' possibl}' be identical with 

 Tabanus consans;uineus, Macquart, which has however ^^ellowish 

 legs.

The type of Tabanus fulvimedius is a $ from Nepal (Hard- 

 wicke Bequest), in bad condition, in the description the locality 

 is given as doubtful : there is another 9 in the Brit. ]\Ius. coll. from 

 N. Chin HiU, Burma. 



There is no doubt that both the Bigot species are identical, 

 though the frontal callus in pagod'iius varies slightly, having a 

 narrower prolongation, described by Bigot as " fortement retrecie au 

 milieu, " he also mentions another callosity on the vertex — which, 

 however, only appears owing to denudation — and the presence of 

 black pubescence. The three bands on the eyes are just dis- 

 cernible. 



In Dr. Kertesz's collection there is a long series of females 

 from Formosa, in ver^- good preservation, with the pubescence on 

 the abdomen perfect. 



The species is very nearly allied to Tabanus orientis, Walker, 

 the only apparent difference being in the more widely black apex, 

 the last four segments being dark in this species. The wings are 

 tinged with brown, 



A medium-sized reddish brown species, with a rather broad 

 forehead about six times as long as it is broad, onl}^ slightly narrower 

 at the vertex, with a large oblong callus prolonged as a thick linear 

 extension. Antennae red, palpi slender, reddish yellow with black 

 pubescence. Abdomen reddish brown on the first three segments, 

 black on the remaining ones with narrow yellow segmentations, 

 when undenuded with large greyish 3^ellow haired more or less 

 triangular-shaped median spots on each segment, forming a con- 

 tinuous stripe. Legs black, the tibiae reddish yellow. Wings 

 usually with a short appendix and slightly tinged brown. Length 

 15-16 mm. 



The series from Formosa have the abdomen blacker, often only 

 the first two segments being reddish yellow and not always entireh- 

 so. The wings are very distinctly tinged l)rown often without an 

 appendix.

Black. Abdomen with three white stripes,, the lateral ones 

 not reaching the apex. Legs red. Length 5.^ lines.
