SPECIES OF TABANUS.—PART I. 28] 
Tabanus copemani, sp. n. 
O.—Length (5 specimens) 12°4 to 14 mm.; width of head 4:2 to 4°8 mm.; 
width of front at vertex 0°6 to 0°75 mm.; length of wing 9°6 to 11°5 mm. 
Medium-sized ov smallish, dark-coloured species.—Dorsum of thorax blackish slate- 
coloured, somewhat shining, with two conspicuous, grey, admedian, longitudinal 
stripes ; dorsum of abdomen clove-brown, hind border of first segment and greater 
part of second and third segments greyish cinnamon-rufous, hind borders of fourth 
and following segments greyish isabella-coloured and, except in case of last segment, 
clothed on each side with appressed, whitish hair ; wings faintly tinged with drab, 
stigma narrow and elongate, mummy-brown ; legs clove-brown or black, tibiae, ex- 
cept tips of middle and hind pairs and rather less than distal half of front pair, 
eream-coloured, and clothed with appressed, glistening white hairs. 
Head grey (subecallus when denuded dark brown), face, jowls, and basioccipital 
region clothed with whitish hair; front of moderate breadth, about three and a 
half times as long as broad, inner margins of eyes bordering it almost or quite 
parallel, upper two-thirds of front clothed with short black hair, lower third, on 
each side of callus, clothed with short white hair ; frontal callus oblong or roughly 
quadrate, often with its upper angles more or less rounded off or otherwise ob- 
literated, dark brown or chestnut-brown, narrowly separated from eye on each 
side, and prolonged above into a raised median line ; palpi dusky (mouse-grey 
or dark grey), clothed on outer side with whitish hair, terminal joint acuminate, 
moderately stout at base ; first and second joints of antennae greyish clove-brown 
or brownish grey, clothed with black or blackish hair, third joint more or less 
chestnut, chestnut-brown, or cinnamon-rufous (sometimes entirely dark brown 
except at extreme base, sometimes entirely cinnamon-rufous except at extreme 
tip), expanded portion of third jot moderately broad, not elongate, terminal 
annuli fairly long. Thorax: dorsum clothed with erect, black or blackish hair, 
denser on scutellum, in front of suture also with minute, appressed, buff-yellow 
hairs; immediately above base of each wing is a small tuft of whitish hair ; 
sides and front of dorsum grey, swelling in depression at each end of transverse 
suture drab-grey ; dorsal stripes running from front margin to presutural groove, 
broadening out posteriorly and almost in contact; pleurae and pectus grey, 
clothed with whitish or blackish hair, either the one or the other colour some- 
times predominating. Abdomen: hind border of dorsum of first segment clothed 
with glistening white hair; dorsum of second and third segments each with a 
large, though not sharply defined, clove-brown, median spot, resting on base but 
not reaching hind margin (occupying approximately anterior two-thirds of each 
segment) ; on each side of same two segments is a more or less distinct clove- 
brown blotch (often larger and more conspicuous in case of third segment), in 
contact with base, but not approaching hind margin nearer than median spot ; 
immediately behind median spots on second and third segments is a patch of 
minute, appressed, glistening, whitish hairs, extending to hind margin in each 
case, while behind each of the lateral spots on the same segments is a larger, 
transversely elongate patch of similar hair, extending to the posterior angle ; 
fourth and fifth segments each with a similar patch of minute, appressed, 
glistening, whitish hair on posterior half on each side, and also with a smaller,
