190 Annals of the South African Museum. 



Anal appendages of the male yellowish-brown ; lower margin of 

 appendages (seen from side) with a triangular projection near base. 

 Femora and tibiae pale brown ; tips of femora with a black band, and 

 tips of middle and hind tibiae with a narrow black band. Joints of 

 fore and middle tarsi brown, becoming blackish-brown towards the 

 tip ; joints of hind tarsi blackish-brown. First joint of hind tarsus 

 as long as second and third united, which are equal ; fourth joint two- 

 thirds of first; fifth joint almost as long as fourth. Hind femora 

 rather incrassate in the middle. Wings very long and slender with 

 elliptical apex. Membrane hyaline with hardly any yellowish tinge 

 nervures dark brown, narrowly margined with brown, especially in the 

 apical part. 



Pterostigma subrectangular, five or six times longer than broad, 

 strongly brownish coloured (purple-brown in the specimen in British 

 Museum). Between Sc and R a cross-vein, in the forewing placed 

 about in the middle between the origin of Us and the fork of Rs, in 

 the hind wing nearer to the origin of Rs. Fork of Rs a little nearer 

 to the base of the wing than the fork of M. The cross-vein between 

 Gu l and Cu~ much before fork of M, but further out than the cross- 

 vein between Cu~ and I A. Bristles on the margins of the wings near 

 their base. 



Length of forewing 22-24 mm, ; that of hiudwiug 20-22 mm. 



British Museum : One $ (type specimen) labelled : [388] [Dr. 

 Smith S. Afr. 44-6] [one of Walker's series of so named B. capensis']. 



South African Museum : One labelled : Krantzkloof , Natal, 

 Marley, 10:5:15. 



The specimen in the British Museum was somewhat larger than 

 that in the South African Museum. 



I have only seen these two specimens of the species, and it seems to 

 be a very rare one. 



The species much resembles the species of the Australian genus 

 Harpoliittacus, but it is easily separated by the longer first tarsal joint 

 of the hind tarsus and the especially long and narrow wings.
