Head very broad, black, with a sparse brown pollen ; vertex 

 with numerous, mostly proclinate bristles ; vertex between 

 the small eyes very broad. 



Pronotum moderately conspicuous, dark brown ; scutum 

 transversely rectangular ; prosternum moderately broad, 

 separating the fore coxae; Mesonotum shiny black through- 

 out. Pleura similar with a sparse brownish pollen. 

 Halteres brown, the base of the stem paler brown, the knobs 

 dark brownish black. Legs with the cox?e very large, black ; 

 trochanters reddish brown ; legs black, the bases of the 

 femora rather bright yellow, this narrowest on the fore legs 

 where it occupies a little more than the basal quarter, 

 broadest on the hind legs where about a third of the femur 

 is included ; femora rather stout. Wings yellowish sub- 

 hyaline with a rather heavy brown pattern, distributed as 

 follows : at h ; in the basal cells extending from C to vein 

 1st A, lying a short distance beyond the arculus ; an inter- 

 rupted cross-band at the level of the origin obRs, consisting 

 of a large rounded spot at the latter position and a still 

 larger, hour-glass shaped mark extending from cell M to the 

 wing-margin at the end of vein 2nd A, narrowest at vein 

 1st A, this band interrupted on both sides of vein M in 

 cells R and M ; the third area consists of a similarly inter- 

 rupted band at the cord, broadest at the costal margin, 

 narrowed behind to the fork of M, continued behind this as 

 a broad seam on the basal deflection of C«i, which forks, 

 sending a branch to both 1st A and Cu 2 at the wing-margin ; 

 outer end of cell 1st M 2 seamed with brown ; a small spot 

 at the fork of M i+2 ; conspicuous rounded brown clouds at 

 the ends of all the longitudinal veins, those at the wing-tip 

 being confluent across cells R 2 to Mi ; a large rounded spot 

 at the middle of cell 2nd A ; veins yellow, dark brown in 

 the darkened areas. Venation : Sc ending immediately 

 before the fork of lis, Sc 2 at the tip of Sci ; Rs long, 

 straight, forming an acute angle at its origin ; R 2+ z short, 

 about equal to r-m. ; r near the tip of R t and at about mid- 

 length of the long R 2 ; basal deflection of R i+5 about one- 

 half longer than r-m ; inner ends of cells R 3 and R 5 almost 

 in alignment or the latter a little more distad ; cell 1st M 2 

 rectangular, the basal deflection of Cu x at about three-fifths 

 its length ; cell 1st M 2 a little longer than its petiole ; forks 

 of vein Cu about equal ; 2nd Anal vein sinuous. 



Abdomen shiny black, the ninth pleurites and appendages 

 conspicuously reddish ; pleural appendages slender, gently 

 curved, decussate. 

 Hab. Abyssinia.
