cence, slightly deflexed from the middle to the apex. Eyes 

 separated on the vertex by a distance nearly equal to the 

 combined length of the two basal joints of the flngellum ; 

 second joint of the flagellum distinctly longer than the third. 

 Median segment more than half as long again as the 

 scutellum, with a very obscure impressed median line; the 

 posterior slope rather indistinctly transversely striated, with 

 a deep median sulcus ; pubescence of the thorax and median 

 segment greyish and very sparse. Dorsal surface of the 

 abdomen densely covered with golden pubescence, which is 

 denser and brighter on the apical than on the basal half of 

 the segments; apical half of the fifth dorsal segment and 

 basal half of the first without golden pubescence. Pygidial 

 area elongate, very narrowly rounded at the apex, densely 

 clothed with short setae, which change according to the light 

 from fulvous-gold to black. Second ventral segment shining, 

 with sparse and fairly large punctures. Basal joint of the 

 fore tarsus with six spines. Second abscissa of the radius a 

 little longer than the third, both being distinctly longer than 

 the space between the two recurrent nervures. 



^a6. Uganda; Eastern Mbale district, S. of Mt. Elgon, 

 3700 ft., August 2-6 ; Mbale Kumi road, S. of Lake Salis- 

 bury, 3700 ft., August 15-17 ; between Kumi and N.E. shore 

 of Lake Kioga, 3600 ft. {S. A. Neave) ; Entebbe, August 15

This is very near T. mira. Kohl, but differs in the dark 

 fore wings, in the distinctly greater distance between the 

 eyes on the vertex, in the coarser pubescence of the pygidial 

 area (this area being also rather narrower at the apex), and in 

 the greater size. 



The male of this species differs from the male mi'ra in the 

 infuscate fore wings, in the shape of the seventh dorsal 

 segment, which is truncate at the apex, not very broadly 

 rounded as in mira (this segment in both species is veiy 

 broad, not narrow as in ohservabilis, Kohl) ; the eighth ventral 

 segment is much more shallowly emarginate, with shorter 

 teeth at the apical angles than in mira.
