(5 . Feminoe similis ; capite pallide aureo-pubescente ; flagello- 



articulis 2-7 infra fortiter arcuato-dilutatis. 

 Long., J $ , 14 mm. 



? . Clypeus subtruncate at the apex. Eves separated on 

 the vertex by a distance not quite equal to the length of the 

 two basal joints of the flagelluni. Pubescence of the thorax 

 very sparse and pale, longer on the sides of the median 

 segment. Abdomen ratlier slender, the basal segment not 

 quite as broad as the second ; second sternite opaque, 

 minutely and closely punctured, with sparse larger punc- 

 tures ; pygidial area elongate-triangular, narrowly rounded 

 at the apex, clothed densely Avith reddish gold pubescence. 

 Basal joint of fore tarsus with five spines. 



cJ . Eyes separated on the vertex by a distance equal to 

 the length of the third joint of the flagellum ; seventh 

 tergite truncate at the apex, the sides convergent from the 

 base ; eighth sternite broadly subtruncate at the apex, the 

 apical angles not produced.

 4000 ft. (S. A. Neave), April 30-May 1, 's ; Tganda Pro- 

 tectorate, between Kumi and N.E. shore of Lake Kiogn,

This is near T. aurichulcea. Kohl, but is a more slender 

 species, with differently coloured wings, and also differs in 

 the clypeus, the slightly narrower space between the exes, 

 and in the male antennte and apical segments. This belongs 

 to the section of the gentis in which the galea is short and 

 broadly rounded, not rostrate.

J. Niger; segmeiitis abdorainalibus margine apicali brunneis ; 

 calcaribus uuguiculisque ferrugineis; froute clypeoque sub-

 pallide aureo-griseo-j)ubescentibus ; segmentis dorsalibus aureo- 

 pubescentibus, fasciis apicalibus distinctissimis ; alis tlavo- 

 hyalinis, venis ferrugineis, 



Long. 12 mm. 



(J . Clypeus very broadly rounded at the apex -, galea 

 much shorter than the scape; vertex rather indistinctly 

 punctured ; eyes separated on the vertex by a distance 

 slightly exceeding the length of the second joint of the 

 flagellum. Thorax very closely and minutely punctured ; 

 median segiuent finely rugulose, twice as long as the 

 scutellum. Abdomen rather slender ; second sternite
