ASBOLEOLA ELEGANS, n. sp. 



$ . Head white ; orbits fuscous behind, more or less tinted with 

 flavescent golden in front, a coloration which spreads on the genae ; 

 peristome greyish blue. Thorax with the terguin somewhat shiny 

 black, like the scutellum ; shoulders and pleurae with a whitish indu- 

 mentum. Abdomen with the 2 first segments dark opaque, somewhat 

 shiny on the last ones ; segments 2 and 3 reddish on the sides and on 

 the venter ; a wide, cream-white, very thick band on the anterior part 

 of segment 3, narrowed on segment 2, slightly greyish blue and not 

 very noticeable on segment 4. Wings moderately ample, clear at base, 

 then soon inf uscate along the nervures ; posterior transverse a little 

 oblique, weakly siuuose. Squamae whitish, the inferior with a thick 

 white or yellowish border. Halteres wholly yellow. Legs long and 

 black. 



9 . Facies and colour of Pyrrhosiella cint/ulata, but distinguished 

 from it by the larger size, the 2 orbital setae, the fuscous nervures 

 of the wings and the small discal setae on the 4th abdominal segment. 



Length 10-11 mm. 



ISTyassaland, Mt. Mlanje(S. A. Neave). Numerous examples. 



ASBOLEOLA ANGUSTIPENNIS, n. sp. 



I have seen 3 3 only of this species. They differ from the preceding 

 species merely by the longer and very narrow wings, which are more 

 uniformly smoky, with the more oblique apical and posterior trans- 

 verses, and by the abdomen, which is black, without trace of red 

 on segments 2 and 3. 



Length 11-12 mm. 



The validity of this species is not well established ; in a $ from 

 Euvenzori, collected by Dr. J. Bequaert, the abdomen is that of A. 

 angustipennis, and the wings those of A. elegans. It is probable 

 that the genus Asboleola is also represented in South Africa.

GEN. PHOROSTOMA, Rond. 



PHOROSTOMA RUTILANS, n. sp. 



Several $ examples with the facies of the palaearctic Gynmodexia 

 triangulifera Zett ; but with 2 + 1 sternopleural setae, and the 

 abdomen reddish and without black triangular spots. Segments 1 and
