the second joint of the fl;if^ellum. Thorax and median seg- 

 ment very closely and minutely punctured, rather thinly 

 covered with very short, delicate, golden pubescence ; the 

 posterior slope ot" the median seoaient iinely transversely 

 striated, with a deep median sulcus. Pygidial area elongate- 

 triangular, shining, sparsely and rather strongly punctured, 

 very narrowly truncate at the apex. Comb of tlie fore tarsi 

 long ; tibia3 with short golden pubescence. Radial cell 

 rounded at the apex, not truncate, third abscissa of the radius 

 longer than the second, which is equal to the space between 

 the recurrent nervures on the cubitus. Tarsal ungues very 

 lono;, as in the genus Notogonia.

This seems to belong to the group of T. quadricolory 

 Gerst., but is a smaller and less robust species, and the eyes 

 are nearer together on the vertex; the colour of the wings is 

 also dilFerent. The elongate ungues are very remarkable.

Long. 12 mm. 



? . Clypeus very broadly rounded at the apex, somewhat 

 deflexed from the middle, the apical half shining, with a few 

 large scattered punctures ; the base of the clypeus and the 

 front clothed with very short, sericeous, silver pubescence. 

 Thorax closely microscopicall}'' punctured, the mesonotuni 

 and scutellnm bare ; dorsal surface of the median segment 

 opaque, very closely and microscopically punctured, the sides 

 of the segment obliquely, the aj)ex transversely striated. 

 Abdomen slender ; pygidial area elongate-triangular, sparsely 

 I)unctured. No pubescent fascise on the dorsal segments. 

 Tarsal comb long, the basal joint of the fore tarsus with eight 

 spines. Radial cell broadly rounded at the apex ; second 

 abscissa of the radius longer than the third, which is longer 

 than the space between the recurrent nervures on the cubitus.

A very slender species, easily distinguished by tlie fuscous 

 wings from any other Ethiopian species with the abdomen red.
