TABANINAE. — PART IV. 291 



(cream-buff) ; pale bauds on tibiae clothed with short, glistening, ochreous hair, 

 front tibiae sometimes with an indication (faintly marked but clothed anteriorly 

 with a few glistening ochreous hairs) of a second pale band towards distal 

 extremity ; hind coxae clothed below with pale yellowish hair ; legs except as 

 stated, clothed with short, dark brown, hair ; front tibiae slightly thickened 

 beyond pale band, but neither front nor hind tibiae really incrassate. 



Belgian Congo : type from R. Congo, opposite Coquilhatville, 1. x. 1910 

 {Dr. A. Yale Massey*) ; a second specimen (para-type) from Bolombo, R. Congo, 

 8. x. 1910 {Dr. J. Bequaert : — in the Musee du Congo Beige, Tervueren, Belgium). 

 A third Q of this species, from Lisala, R. Congo, 22. iii. 1909 ( — Waelbroeck), 

 is in the collection of the Musee National D'Histoire Naturelle, Paris. 



As indicated at the end of the description of the foregoing species, Haemato- 

 pota harpax is closely allied to H. hastata, the points of difference from which 

 have already been alluded to above. Shortly stated, Haematopota harpax is 

 distinguishable from H. hastata by its darker palpi, by the first joint of its 

 antennae being less shining, by the distal angles of the second joint of its antennae 

 being produced into thumb-shaped processes, by the pale wing-markings being 

 coarser, sparser, and less complex, and by the hind tibiae having a second pale 

 band. 



Haematopota maculosifacies, sp. n. (fig. 3). 



Q. — Length (9 specimens) just over 7 to 8'4 mm. ; width of head 2*75 to just 

 over 3 mm. ; width of front at vertex 1 to just over 1 mm. ; length of wing 6*4 

 to 7 mm. 



Small blackish species, with slender, elongate antennae, and on the face, below the 

 latter, a transverse row of four sharply defined, clove-broivn spots. — Front 

 relatively broad, and broader below than on vertex; dorsum of thorax olive-brown, 

 with grey markings not very extensive nor conspicuous ; dorsum of abdomen blackish 

 clove-brown {darker than thorax), ivith grey markings as shown in fig 3 ; icings 

 mouse-grey or light sepia-coloured, with clearly defined pale markings as shown in 

 fig. 3, usual apical sinuous mark appearing as a nearly straight transverse band. 



Head, : light grey pollinose, front except extreme lateral margins and a narrow 

 ring surrounding each lateral frontal spot, darker, vertex with an olive-brown 

 blotch narrowly divided in middle line by a fine grey or cinereous stripe which 

 extends to median frontal spot ; all three frontal spots present, median spot very 

 small and inconspicuous, lateral frontal spots large, rounded, not in contact with 

 eyes ; front above callus sparsely clothed with short, yellowish hair, and clothed 

 on vertex with dark brown hair ; frontal callus a shining black transverse band 

 of moderate depth, extending from eye to eye, its upper margin usually rising 

 in middle line to a more or less well-marked angle ; a single, well developed, 

 quadrate, clove-brown spot in middle line, below frontal callus (with lower 

 margin of which it is in contact) and between bases of antennae ; face, jowls, and 

 basioccipital region clothed with glistening whitish hair ; in the transverse row of 



* Writing to the author from Coquilhatville, on 26. xi. l'JIO, with reference to this specimen, 

 Dr. Yale Massey said: " This is the only Haematopota met with so far. The wet season has 

 now set in, but these flies do not seem to be here as yet."
