specimens of this South African species, which is still represented 

 in the National Collection only by the types of the male and female. 

 Although described so long ago as 1848, the species does not appear 

 subsequently to have been met with, or at any rate recorded, by 

 anyone, and since the types are merely labelled " S. Africa," with 

 a number indicating that they formed part of a collection of South 

 African insects " purchased from Argent," it is even uncertain 

 whether they were obtained in Cape Colony or Natal. 



The third joint of the antennae being unfortunately missing in 

 the types of both sexes, it has only been possible to indicate it in 

 the figure. In coloration the two sexes are alike, except that the 

 light stripes on the back of the thorax are less distinctly marked 

 in the male.

PLATE III., FIG. 17. 



A thick-set, medium-sized, dusky species, which has hitherto been 

 met with only in Uganda, and of which the Museum possesses seven 

 females, from the following localities : Kyadondo, 1903 (Colonel 

 Sir David Bruce, C.B., R.A.M.C., F.E.S.} ; Singo, 1903 (Colonel 

 Sir David Bruce) ; Busoga, March, 1906 (Dr. A. D. P. Hodges}', 

 and the Nile between Wadelai and Nimule, 1906 (the late Dr. W. A. 

 Densham). With reference to the example obtained by him, Dr. 

 Densham wrote : " Only specimen seen ; taken at an opening in 

 the swampy river edge."
