1. U. bilineata, Theo., Mon. Cul. V, p. 517 (1910). 



This is a very distinct species, being, with U. connali, the only African species 

 with a white line on the pleurae and banded hind tarsi. U. connali, indeed, may 

 eventually prove to be only a well-marked variety of U. bilineata, but as the 

 material is so scanty it is described provisionally as distinct. Both have the first 

 longitudinal vein clothed with white scales to the middle, a character possessed by 

 none of the other species. 



U. bilineata, var. fraseri, nov. Two females from Mpumu Forest, Uganda 

 (Capt. A. D. Fraser), were at first thought to represent a distinct species, as the 

 legs appeared to be unbanded, and there are faint traces of basal pale bands on 

 the fifth, sixth and seventh abdominal segments. However, a close examination 

 in a good light revealed traces of the same leg-banding as is present in 

 U. bilineata, and as these specimens are quite typical in other respects, they must 

 be regarded as only a variety of the present species. Specimens of the typical 

 form have been received from the same place.

cJ Q . Head clothed with dark, fuscous brown, flat scales in the middle, with a 

 rather narrow margin of whitish blue flat scales ; two or three very long, whitish 

 blue scales project over the front ; a row of black upright forked scales round the 

 edge of the dark area, and a few more on the nape. Proboscis, palpi and 

 antennae brown. Thorax : mesonotum dark reddish brown, clothed with dark 

 brown scales, those on the scutellum flat ; a row of large flat bluish white scales 

 extending forwards from the wing-base for half the length of the thorax ; pleurae 

 dark brown, with a median longitudinal line of flat bluish white scales ; this line 

 extends across the prothoracic lobes ; a few similar scales above the bases of the 

 coxae. The integument bordering both these lines is darkened. Metanotum
