igii.J G. RiCARDO : Revision of the species of Tab^-WViS. I2q 



Tabanus hirtipalpis, 2 , n. sp. 

 (PL xiii, figs. 2, 3.) 



Type from Bichiakoh, Nepal ; sent in Indian Museum col- 

 lection. 



A small black species allied to Tabanus ceylonicus, vSchiner, but 

 at once distinguished from it by the wide forehead with two callosi- 

 ties and the hairy palpi, and by the metatarsi being black. Length 

 9 mm. 



Face black covered with ashy grey tomentum and with long 

 white hairs. Palpi stout ending in a fine but short point, pale 

 yellowish covered with grey tomentum, and with long white hairs 

 at base and below, some few black hairs visible on dorsum. 

 Antennae reddish yellow, black at apex, the first two joints with 

 black hairs, the third joint rather short with small tooth. Fore- 

 head about four times as long as it is broad, slightly narrower 

 anteriorly. Subcallus shining yellow, convex, divided b}" a narrow 

 interval from the frontal callus which is black, transverse, not 

 reaching the eyes, furrowed laterally ; beyond it appears, separated 

 from it however, a small indistinct black callus ; the forehead dark 

 with brownish tomentum. Thorax and abdomen black, shining, 

 the latter with very narrow 3^ellowish red segmentations, some 

 white hairs at sides and on under side. Legs black, the fore tibiae 

 to apex, and the others wholh% yellowish white, fore coxae and all 

 femora with some white hairs. Wings hyaline, veins and stigma 

 brownish yellow. 



Tabanus bicallosus, & 2 , Ricardo. 

 (PI. xiii, fig. 4.) 



Ann. Mag. Nat. Hist. (8), iii, p. 489 (1909). 



Type ( & ) from Pusa, Bengal. 



Type ( 9 ) and three other females from the same place. 



These specimens were sent to me for identification by 

 Mr. F. M. Howlett from India. 



This small species might at first sight be taken for a small 

 specimen of Ta&rtfm.s s^n'a/ws, Fabr., but is at once distinguished 

 from it by the two separate calli of the forehead. It is very nearly 

 allied to Tabanus gratm, Loew, which is distributed over South, 

 Central, and West Africa, reaching up to Kgypt, as I had a speci- 

 men sent me from the Suez Canal. The wholly yellow legs, 

 narrower median stripe of abdomen the same width throughout (in 

 the African species it is wider on the third and fourth segments) , 

 and the prolongation of the thoracic stripes on to the scutelluni . 

 seem the only differences between the Indian and the African 

 specimens.
