yellowish grey tomentum, and with two very indistinct grej" stripes. 

 Under side of abdomen j^ellow with blackish median stripe. Legs 

 yellowish red, femora reddish brown, covered on the under side 

 with dense yellow-grey tomentum, and chiefly whitish pubescence, 

 the apices of tibiae, and tarsi reddish brown, some white hairs 

 on the tibiae, otherwise the pubescence on tibiae and tarsi is black. 

 Wings h^^aline, tinged faintly with yellow, stigma yellow, veins 

 yellow-brown. In Walker's type the abdomen has segmentations 

 and a faint median stripe, paler. 



Rondani labelled two specimens (females) from Sarawak as 

 Tahanus dives, but on examining these specimens it was clearh^ 

 evident they belonged to two different species, the one measuring 

 22 mm. with a uniforml}^ coloured yellowish abdomen marked with 

 no spots is identical with Tahanus univentris, Wlk. The des- 

 cription was evidently drawn up from an examination of both 

 specimens. The smaller specimen is probably nearly allied to or 

 identical with Tabanus stantoni , see page 174. 



Tabanus flavissimus, $ , n. sp. 



Type 9 from Pundaluoya, Ceylon (Green), and another 9 

 likewise from Ce^don. 



A large bright yelknv-bodied species nearly allied to Tabanus 

 fulvissimus , Rondani, but distinguished from it by the narrower 

 forehead, not parallel, and by the smaller narrower frontal callus. 

 It is a larger species than Tabanus univentris, Walker, to which 

 it is related in the shape of the forehead and frontal callus, but 

 has wholly yellow legs and antennae, and the thorax is yellowish. 

 Length of type 24 mm., the other is 20 mm. 



Face, palpi, antennae, forehead, whole body, and legs uniformly 

 fulvous, the colour of Tabanus par, Wlk., a South African species 

 Abdomen a brighter yellow. The pubescence of palpi black, they 

 are long, rather slender, ending in a point. Beard brownish yellow, 

 long, AniennaeXow^ and slender, the third joint narrow at base with 

 hardly any tooth, its apex with some hairs, the first two joints 

 with yellow pubescence. Forehead about seven times as long as 

 it is broad, and barely a third narrower anteriorly, the frontal 

 callus yellow, narrow, not reaching the eyes, with a lineal exten- 

 sion. Thorax (denuded) with whitish yellow hairs at sides and some 

 white pubescence. Abdomen with yellow pubescence, thicker on 

 the apical half ; under side similar. Legs with chiefly short black 

 pubescence. Wings yellow on costal border, tinged narrowly yellow 

 on all the longitudinal veins, appendix present, stigma yellow, 

 veins yellow. 



Tabanus pauper, Rondani. 

 Ann. Mus, Civ. Genova, vii, p. 456 (1875). 

 Length 20 mm. 



9. Dull brown; the forehead sul)luteous, the linear callus 

 pitchy red. Antennae brown-red, the apex, and the lirst two joints
