fore femora with the basal three-fifths yellow, the slightly 

 incrassated apex black ; hind femora with the basal half dull 

 yellow, passing into dark brown; tibiae dark brown, tipped 

 with black ; tarsi black. Wings subhyaline with three narrow 

 brown cross-bands, the first at the level of the origin of the 

 sector, most evident at the origin of the sector and the end 

 of vein 2nd -4, very pale and indistinct in the intervening 

 cells ; the second band is located along the cord, broadest 

 at costa, extending to the fork of Cu and thence as a much 

 paler cloud to the wing-margin ; the third band occupies 

 the wing-apex, the inner margin almost straight, including 

 the extreme tips of cells 2nd R x and A/ 3 , about the outer 

 third of cells i? 3 , R 5 , and 2nd M 2 ; veins dark brown, veins C, 

 Sc, and the wing-base more yellowish. Venation : Sc ending 

 beyond mid-length of the long sector, Sc 2 far back from its 

 tip, nearer to the origin of lis than to the tip of Sc x ; cell 

 Is/ M 2 long and narrow, widened distal ly, a little longer 

 than vein Cuy beyond it ; basal deflection of Cu x near the 

 inner end of cell 1*/ M 2 . 



Abdomen shiny black. Ovipositor reddish horn-colour, 

 the bases of the sternal valves black ; tergal valves of the 

 ovipositor long and slender, strongly upcurved, the tips 

 acute.

Type in the collection of the British Museum (Natural 

 History). 



Teucholabis nodipes, Speiser (Cameroun), has the meso- 

 thorax largely shiny black and the brown wing-pattern more 

 extensive. 



Teucholabis latifascia, sp. n. 



Male. — Length about 7 mm.; wing G'7 mm. 



Female. — Length about 7 mm. ; wing G'2 mm. 



Very similar to T. rubrithorax, differing as follows: 

 The wing-apex and the brown baud at the cord are much 

 broader, the apex including about the outer third of cell 

 2nd R u nearly the outer half of cell R 5 , and the outer three- 

 fourths of cell 2nd M 2 ; the band at the cord is approximately 

 one-half as wide as the hyaline band between it and the dark 

 apex ; the latter is approximately as wide as, or wider than, 

 this hyaline band; the basal baud is but little narrower 

 than the band at the cord. Cell 1*/ M 2 is longer, slightly 

 exceeding in length that portion of vein Cu 1 beyond it ami 

 subequal to vein M z beyond it.
