Tin' Crane-flies ,,f No///// A /rim. 201 



Venation : Sc rather long, extending to beyond one-third the length 

 of the long sector; r rather indistinct, connecting with _R 2 just beyond 

 the base ; cell R. 2 very deep ; tip of vein M^ lying free in the membrane, 

 the basal connections atrophied ; if it were connected with vein Cu (as 

 in G. brevifurca) the fork would be very deep, there being about ten 

 equidistant niacrotrichiae on the preserved portion of M 3 . 



Abdominal tergites pale reddish-brown, broadly margined caudally 

 and laterally with yellow ; hypopygium jet black, the ninth tergite 

 with a yellow dorsal semi-lunar mark at the base and a less distinct 

 mark on either side ; sternites light yellow. Hypopygium suddenly 

 narrowed, small, its general structure somewhat as in G. brevifurca ; 

 ninth tergite narrow, with a profound median split, the lateral lobes 

 very slender, slightly down-curved, covered with a short pubescence ; 

 ninth pleurite produced caudad into a slender finger-like lobe ; three 

 pairs of appendages project from a genital chamber, most of which 

 seem to be pleural appendages ; the longest pair are apparently 

 attached to the steruite, are flattened basally, light brown, the tips 

 slightly curved and blackened, near the base on the outer face with 

 a short spine ; the other spines are shorter and are more pleural in 

 position. 



Habitat. South Africa. 



Holotype, , French Hoek, Cape Colony, altitude 2500-3600 ft,, 

 December 4th, 1916 (K. H. Barnard). 



Type in the South African Museum. 



This beautiful crane-fly is very similar in its general appearance to 

 G. brevifurca, Alexander, but is readily told by the venation and 

 details of body coloration, as diagnosed above. 



GEN. TEENTEPOHLIA, Bigot. 

 1854. Ann. Soc. Ent, France (3rd ser.), vol. 2, p. 473. 



(This genus was not used in Part I of this series, Mongoma, West- 

 wood, being substituted. However, Trentepolilia, is the older name, and 

 there seems to be no just reason for not adopting it.)
