the hypopygium, and on each side of the genital orifice, is a raised 

 lamella which is vertically truncate posteriorly. The outer margins 

 of the hypopygium at its base are also raised and curved, so as to 

 form a shorter and more obtuse lappet on each side. Cape." 



I have copied the author's description, excluding only those 

 remarks in which comparison is made with the Indian D. laevigatus 

 (glaberrimum). The above description of furcatus was published as 

 far back as 1872, and as far as I am aware no species of Dorylus 

 with unattached $ £ , to which this 5 might be ascribed, is known 

 from the Cape even now. Without having seen the original 

 specimen it is not possible to form any definite conclusion, yet a 

 comparison made between the above description and a helvolus ? , 

 in the collection of the South African Museum (described p. 118, ante),, 

 suggests to my mind a strong probability that Gerstaecker's species 

 is only an individual aberration of helvolus, or at the most only a 

 variety of that species.

The type species appears to be confined to the northern portion of 

 Africa, and is replaced in equatorial and S.E. tropical Africa by the 

 following race, which has not been recorded to my knowledge from 

 temperate South Africa. 



The sub-genus includes only this species and D. labiatus of the 

 Indian region.
