TABANINAE. — PART IV. 285 



extremity than in centre ; transverse band clothed with minute, appressed, 

 whitish or silvery-white hairs, and a small and not sharply defined patch of 

 similar hairs usually more or less distinctly noticeable in centre of hind margins 

 of dorsal scutes of second and third segments ; dorsum elsewhere clothed with 

 minute, appressed, ochraceous hairs ; lateral margins of dorsal scutes of first and 

 second segments clothed with longer, whitish hairs, those of dorsal scutes of 

 fourth and fifth segments clothed with outstanding dark brown hair ; venter 

 greyish-buff, clothed with minute, appressed, glistening, cream-buff hairs. 

 Wings : a broad hind border, extending from dark brown apical fleck to distal 

 extremity of axillary cell, grey ; between this hind border and distal margin of 

 transverse band, from marginal to third posterior cell, is a milky stripe which 

 follows outline of transverse band.* Squamae isabella-coloured. Halteres : 

 knobs sepia-coloured or mummy-brown, stalks isabella-coloured. Legs : front 

 coxae cream-buff, middle and hind coxae smoke-grey ; tibiae not incrassate ; all 

 coxae, and middle and hind femora except distal extremities clothed with whitish 

 hair, remainder of legs clothed with blackish hair, hind tibiae fringed on outer 

 side with fine black hair. 



Angola : type and four other specimens from Lepi, Benguella (390 kilometres 

 inland from Lobito Bay), alt. 3,500 feet (collected and presented by E. Robins). 



Ckrysops pallidula is evidently allied to C. inflaticornis, Austen, which is found 

 in the Cape of Good Hope Province of the Union of South Africa. While, 

 however, these two species resemble one another in the shape of the head, 

 coloration of the abdomen, and general pattern of the wing-markings, Ckrysops 

 pallidula. can be distinguished from C. inflaticornis by, inter alia, the first joint of 

 the antennae being less swollen, the dorsum of the thorax being paler and devoid 

 of conspicuous longitudinal stripes, and by the apical fleck in the wing being 

 narrower, darker, and much more sharply defined. 



TABANINAE. 



Genus Haematopota, Meigen. 

 Haematopota hastata, sp. n. (fig. 2). 



(5 Q. — Length, <$ (10 specimens) 8*5 to 10 mm., Q (14 specimens) 8*25 to 

 10 mm. ; width of head, S 3*4 to 4 mm., Q 2*8 to 3'5 mm. ; width of front of 

 Q at vertex just over 1 to 1*2 mm. ; length of wing, <$ 8 to 9 mm., Q 8 to 9*8 mm. 



Medium-sized, dusky species, with dark icings marked toith compound rosettes, 

 large and conspicuous antennae in the Q, the third joint (including terminal annuli) 

 in this sex being flattened from side to side and consequently very broad from above 

 downwards (see fig. 2a), and in both sexes with a clove-brown transverse band on 

 face immediately below antennae, and with hind tibiae marked with a single narrow 

 pale band near base, though indistinct traces of a second band on distal half arc 

 sometimes visible. 



Head : light grey pollinose ; front in Q fairly broad (slightly wider anteriorly), 

 sepia-coloured or mouse-grey except lateral margins and a narrow median stripe 

 running from vertex to median frontal spot, which is distinct and surrounded by 



* In fig. 1 the milky stripe is incorrectly shown as extending into the fourth posterior cell.
