(H. P. Thomasset) ; Mashonaland, Salisbury (G. A. K. 
Marshall), January ; Natal, Estcourt; Zululand, Mfongosi. 
This may be distinguished from znevorahilis and transvaal- 
ensis by the greater approximation of the eyes on the vertex, 
especially in the male; and by the yellower colour of the 
wings. 
45. Tachytes pulchricornis, sp. n. 
g. Niger; fronte clypeoque pallide aureo-pubescentibus ; pronoto, 
mesonoto lateribus, postscutellogue subargenteo-pubescentibus, 
pleuris segmentoque mediano sparse albido-pilosis; segmentis 
dorsalibus 4 basalibus fascia apicali griseo-argenteo-pubescente ; 
segmento dorsali septimo argenteo-pubescente ; flagello articulis 
4-9 subtus brunneo-ochraceis; tarsis brunneo-ferrugineis; alis 
hyalinis, pallidissime flavidulis, nervis testaceis; tegulis testaceis. 
©. Mari simillima; flagello omnino nigro; fronte clypeoque 
argenteo-pubescentibus ; area pygidiali rufo-aureo pubescente. 
Long., ¢ 2, 12-13 mm. 
6. Clypeus very broadly subtruncate at the apex ; vertex 
not distinctly punctured ; eyes separated ou the vertex by a 
distance equal to the combined length of the two basal joiuts 
of the flagellum. Galea short, very broadly rounded at the 
apex; second and third joints of the labial palpi short, sub- 
equal. Median segment about half as long again as the 
scutellum, the longitudinal suleus almost obsolete. Seventh 
tergite rather broadly subtruncate at the apex ; the eighth 
sternite rather broadly emarginate, the apical angles strongly 
produced. Third cubital cell long, extending much beyond 
the apex of the radial cell, at least three-quarters of the 
length of the second on the cubitus. A variety has the 
abdominal fascize dull golden. 
?. Distance between the eyes on the vertex as in the 
male ; pygidial area triangular, acute at the apex ; second 
sternite subopaque, closely microscopically punctured ; basal 
joint of fore tarsus with five spines. A variety has the 
abdominal fasciz dull golden. 
Hab, Nyasaland, Mlanje (S. A. Neave), March. 
Subspecies kolaensis, subsp. n. 
3. Differs from the typical form in having the third to 
ninth joints of the flagellum ochraceous brown above as well 
as below, leaving only a black ring at the joints. 
?. The pygidial area very distinctly broader than in the 
typical form, broadly rounded at the apex.
