sulcus. Second stcriiite subopaque, minutely and closely 

 punctured, with a sliiniun: suhtiiangular space on the middle 

 of the apical margin. Pygidial area trian^rular, narrowly 

 rounded at the apex. Basal joint of fore tarsi with .six 

 spines. First and third abscissae of the radius subequal, 

 each nearly twice as long as the second, and nearly half as 

 long again as the space between the recurrent nervures on 

 the cubitus. Third cubital cell on the cubitus extending a 

 little beyond the apex of the radial cell. 



S . Eyes separated on the vertex I)y a distance not quite 

 equal to half the length of the second joint of theflagoUum ; 

 ])unctures of the second sternite distinctly larger than in 

 the female ; seventh tergite subtriangular, rounded at the 

 apex, the apical angles not produced.

I am doubtful if ]\Iagretti (Ann. !Mus. Civ. Genova, xxi. 

 J). 586, 1884) has correctly identified the species he records 

 from Kassala under this name.

? ^ . Extremely near to T. basilica, Guer., differing in 

 tlie black colour of the abdomen, legs, and antennae in both 

 sexes. The abdominal segments are very narrowly brown 

 on the apical margin, and the gold pubescence on the 

 abdomen is denser and deeper in colour than in T. basilica. 

 The female has the clypeus very broadly rounded at the 

 apex, not subtruncate as in basilica.

This is probably only a geographieal race of T. basilica, 

 ranging over Tropical E. Africa and the southern portion 

 of Tropical West Africa. It occurs in Xyasaland Avith the 

 very similar T. mira, Kolil, but may be distinguished at 

 once by the very ditferent sculpture of the second sternite 

 of the female, and by the much greater approximation of 

 the eyes on the vertex in the male ; also by the number 

 of joints in the palpi.
