14. Tabanus formosiensis Ricardo. 
Females from Takao (19. VII. 1907). 
15. Tabanus perakiensis Ricardo. 
A female from Fuhosho. 
16. Tabanus pallidepectoratus Bigot. 
Big., Mém. Soc. ZooL France, V, p. 658 (1892) [Aty lotus] ; Ricardo, Records 
Indian Museum, IV, No VI, p. 209 (1911). 
The type came from Cochin China. In a small collection sent me 
by Mr. Surcouf belonging to the Paris Museum is a female of this 
species from Haifong, Tongking. The male has not been described, but 
in the Brit. Mus. Coll, is a male from Formosa, and another in the 
Coll, of the Hung. Nat. Mus. from the same island, which are identical 
with the female from Haifong. The eyes have the upper two thirds 
occupied by the large facets which reach beyond the apex of the frontal 
triangle and to the vertex, but beyond the vertex they begin to recede, 
leaving a gradually wider border of the small facets. Palpi yellow with 
black hairs. Face covered with yellow tomentum and with yellowish 
brown hairs. 
Abdomen similar to that of female ; underside with blackish bands 
which almost entirely occupy the last five segments, the segmentations 
fringed with yellow pubescence, the seventh wholly blackish. Length 22 mm. 
males and females. 
The golden yellow pubescence of abdomen is much thicker in the 
female specimen than in the type (owing to denudation in this last) 
and extends as triangular median spots on each segment, and as a 
broad border to each segment posteriorly. 
17. Tabanus candidus n. sp. <j>. 
Type (female) from Formosa. 
A species near Tabanus birmanicus Bigot, but quite different. 
A large black species with a white haired thorax and scutellum. Thorax 
sharply distinguished from the dull deep black abdomen. Antennæ legs 
and palpi blackish. Forehead narrow. Length 21 mm. 
Face covered with dark brown tomentum and with black hairs in 
centre below antennæ and on the cheeks. 
Beard blackish brown. Palpi blackish, slightly stouter at base, ending- 
in an obtuse point. 
Antennæ blackish, the third joint somewhat reddish brown, the 
first two joints with a little black pubescence. Subcallus and forehead 
the same colour as face, some greyish tomentum on forehead above the 
frontal callus. Forehead about seven times as long as it is broad, hardly
