similar, but very scanty. Palin dull reddish, thickly 

 covered with black hairs, large, stout, ending in an obtuse 

 point. Subcallus, forehead, and sides of cheeks covered with 

 yellowish-brown tomentum. Antennae, bright reddish, the 

 apex black ; the first two joints with black pubescence ; the 

 third joint long and slender, the tooth near the base distinct, 

 crowned with a few black hairs. Forehead narrow, about 

 seven times as long as it is narrow, very slightly narrower 

 anteriorly ; the frontal callus dark reddish brown, narrow, 

 oblong, not reaching the eyes, prolonged as a narrow raised 

 line towards the vertex ; hairs on forehead black. Thorax 

 brown, with yellowish-brown tomentum and scattered black 

 pubescence; a few appressed pale yellow hairs are visible 

 chiefly on the anterior half of dorsum and at sides. Scutel- 

 lum similar. Abdomen dull reddish, appearing darker owing 

 to the dense short pubescence ; segmentations obscurely 

 yellowish or lighter, a few white hairs at the sides of abdo- 

 men ; underside brown, but with grey tomentum on the 

 sides and the segmentations, which latter are wider and more 

 distinct; the pubescence black. Z^e^5 with black pubescence, 

 but the fore coxae with long white pubescence ; the fore tibiae 

 reddish at base, the others reddish brown. Wings with 

 brown veins and stigma, tinged with brown on the fore 

 border, becoming paler on the posterior border. 



Tabanus bicallosus, ^ ? j sp. n. 



Type ( ^ ) from Pusa, Bengal. 



Type (?) 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 Tabanus striatus, Fabr., but is at once distin- 

 guished from it by the two separate calli of the forehead. 

 It is very nearly allied to Tabanus gratus, Loew, which is 

 distributed over South, (Jentral, and West Africa, reaching 

 up to Egypt, as I had a specimen 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 pro- 

 longation of the thoracic stripes on to the scutellum seem the 

 only differences between the Indian and the African 

 specimens. 



Black, with five grey stripes on the thorax and three on 

 the abdomen. Legs and antennae yellowish. Wings clear. 



Length 10 mm.
