It has already been pointed out in dealing with the area of 

 distribution of Gl. morsitans that the eastern half of it practically 

 coincides with that of the present species, and reference has been 

 made to the probability that the species that formed the subject 

 of Lt.-Col. Bruce's experiments in Zulu Land was Gl. pallidipes 

 and not Gl. morsitans. Such at any rate is the natural deduction 

 from a comparison of the reproductions of photographs of speci- 

 mens on Plate II. of Col. Bruce's memoir [142] ; on comparing 

 fig. 2 and the right-hand figure of fig. 7, it will be seen that the 

 median pale streak on the abdomen is very narrow, and that the 

 dark interrupted bands extend close to the posterior borders of 

 the segments. The coloured figures on Plate I. are evidently less 

 reliable, and no importance can be attached to the obvious 

 discrepancies between them and the photographic reproductions 

 on the folloAving plate. In the coloured figures the angles of the 

 interrupted dark abdominal bands are shown rounded off, while 

 the pale hind margins are deeper and the median stripe wider, so 

 that to judge from the abdomen these figures would appear to 

 have been taken from specimens of Gl. morsitans. On the other 

 hand, the front tarsi are entirely pale ; but, since the hind tarsi 

 ai'e likewise shown without dark tips, no conclusion can be 

 drawn from this, except that the artist certainly did not examine 

 the legs of his specimens closely. It is quite possible that in his 

 experiments Bruce may haxe made use of both GL inorsitans and 

 G I. pallidipes.
