932 REPORT OF THE HARVARD AFRICAN EXPEDITION 
corners of the first four tergites and a median, triangular, golden spot on the 
third and fourth tergites; the thorax bears dorsally four longitudinal golden 
stripes, the two middle ones abruptly ending at the transverse suture; the 
scutellum likewise is covered with golden pile. J. fulvicapillus is much larger 
and is said to have median golden triangles on the middle tergites (which ones 
is not stated); the median and posterior areas of the thorax were denuded in 
the type and paratype. 
Tabanus niveinotatus, new species 
Female. — Length, 17.5 mm.; width of head, 6 mm.; width of frons at vertex, about three- 
fourths mm.; length of wing, 14.5 mm. 
A dark brown, nearly black species, with a mid-dorsal, triangular, silvery spot on the posterior 
margin of each of the third and fourth abdominal tergites. Scutellum and four entire stripes on 
the dorsum of the thorax also silvery; the two median thoracic stripes somewhat narrowed and 
less pronounced behind the transverse suture. Wing hyaline, with most of the veins margined 
with brownish; stigma nearly black. Legs dark; basal two-thirds of fore tibiae light brown. 
Eyes bare. All the posterior cells open; fork of third longitudinal vein without appendix. 
Head: frons about five times as long as wide, nearly parallel-sided, mottled gray and brown; 
basal callosity opaque brown, not much elevated, nearly as wide as the frons at lower margin of 
eyes, rather oblong and connected above with a linear extension which reaches two-thirds of the 
distance to the vertex; face and cheeks gray pollinose and white pilose; beard white; subcallus 
entirely grayish pollinose. Antenna dark, nearly black in large part; first segment distinctly 
enlarged, reddish brown, produced forward dorsally, everywhere black hairy; third segment 
crescent-shaped, the dorsal protuberance broadly triangular, its apex at the proximal third of 
the basal division. Palpi of normal size, gradually tapering from a swollen base, slightly infuscated 
over a yellowish ground color, black hairy; proboscis black. Thorax black, dorsally with four 
entire, longitudinal, gray stripes: the two middle ones narrowed and less distinct behind the trans- 
verse suture; the two lateral ones connected behind with the white area that covers the entire 
scutellum; sides and venter of scutellum all white and rather long white pilose. Abdomen dark 
dorsally, with a prominent, triangular, silvery, median spot on each of the third and fourth ter- 
gites, not reaching much beyond the posterior half of the tergite and scarcely one-third as wide as 
the abdomen; venter of abdomen brown, more intense in places; posterior margin of each sternite 
very narrowly paler. Wing hyaline; stigma long, dark brown; nearly all of the veins rather ob- 
securely margined with brown. Squamae brown. Halteres brown, with apices of knobs paler. 
Legs: all the femora and tarsi dark brown, nearly black; all tibiae reddish brown and all, especially 
the fore ones, darkened apically; fore tarsi distinctly widened; pilosity of femora mostly gray; 
that of tibiae mostly black. 
Br.eran Conco. — Kabaki near Walikale, one female holotype and one 
female paratype, January 4, 1915. 
This new species belongs in the group with 7’. wellmanii Austen, T. sharpet 
Austen, 7: roubaudi Sureoutf, 7. argenteus Surcouf, and 7. williamsii Austen, 
but may be known from all by the larger size, being five millimeters longer 
than any of the others mentioned. It differs from all of these, too, in having 
complete white stripes on the thorax and by not having white tibiae. It appears 
to be most closely allied to 7. williamsii Austen (1908, Ann. Mag. Nat. Hist, 
(8) I, p. 426; ¢), from Northern Nigeria (Jemaas, Nassarawa Province). That 
species, however, is described as much smaller (12.3 mm.), with the tibiae ex- 
cept tips cream-buff; the light gray stripes of the anterior part of the dorsum 
extend scarcely beyond the transverse suture; the third segment of the an- 
tenna is reddish brown, ferruginous at base, with the last four divisions clove- 
brown.
