more or less distinct patch of similar hairs in and on each side of middle line, 
close to hind margin; sixth segment except at base largely clothed with ap- 
pressed, glistening, whitish hair; seventh segment, base of sixth, and first five 
segments except as already stated clothed with black hair; ventral surface of 
first three segments greyish russet or greyish cinnamon, clothed, like greater 
part of ventral surface of following segment with minute, appressed, whitish hair ; 
ventral scutes of second to fourth segments inclusive with a clove-brown blotch 
in each basal angle; ventral scute of fourth segment, except hind margin and as 
already stated, greyish cinnamon-rufons or greyish brown; ventral scutes of last 
three (except hind margins of penultimate and antepenultimate) segments greyish 
clove-brown, clothed with black hair; hind margins of ventral scutes of second 
to sixth segments inclusive cream-coloured, clothed with whitish hair. Wings: 
veins dark brown; anterior branch of third longitudinal vein sometimes provided 
at base with a minute stump or backwardly directed appendix, which may vary 
in size in the two wings of the same specimen, or even be present in one wing 
and absent in the other. Sqguamae clove-brown or dark sepia-coloured, borders 
darker than disc. //alteres sepia-coloured. Legs : coxae grey and clothed with 
whitish hair, except distal extremities of front pair, which are blackish and 
clothed with black hair (in some specimens front coxae are almost entirely 
blackish and clothed with black hair); hind femora clothed below with whitish 
hair, otherwise femora, tarsi, and distal extremities of front tibiae clothed with 
black hair ; on middle and hind tibiae the glistening white hairs extend on to the 
clove-brown tips; front tarsi enlarged, and the three middle joints expanded, 
NortHeERN Ruopesia and the NYASALAND PROTECTORATE: type and 
three other specimens from the Feira District, Northern Rhodesia, 1911 (4. A. 
Copeman); one specimen from Liwonde, Nyasaland Protectorate, 19. I. 1911 
(Dr. J. B.S. Old: presented by the Entomological Research Committee). 
This species, with which the author has much pleasure in associating the name 
of one of its discoverers, is allied to Tabanus claritibialis, Ricardo, which hitherto 
has been met with only in the Nyasaland Protectorate. Apart, however, from 
the markings and very different coloration of the abdomen, which in 7. claritibialis 
is unicolorous or nearly so, 7’. copemani is distinguished by differences in the 
shape of the third joint of the antennae, as also by its thoracic stripes. In the 
species described above the annulate portion of the third antennal joint is longer 
and the expanded part is usually shorter and broader than in 7. claritibialis, in 
which the grey thoracic stripes, so conspicuous in 7’. copemani, are absent or 
vestigial.

Q.—Leneth (13 specimens) 11 to 13:4 mm.; width of head 4 to 4°6 mm.; 
width of front at vertex 0°6 to 0°8 mm.; length of wing 9°5 to 11 mm, 
Medium-sized or small, blackish, unicolorous species, closely allied to Tabanus 
claritibialis, Rie.—Dorsum of thorax and abdomen blackish slate-coloured, former, 
at least near front margin, with faint indications of grey longitudinal stripes, but 
otherwise thorax and abdomen entirely devoid of markings, except that hind margins 
of abdominal segments, excluding first segment and ventral scute of last, are pale :
