The type is characterized mainly by its unusually large head 

 and it is mainly upon this feature I have connected aurivillii with 

 viator. 



Widely distributed as Hodoiermes s.s is throughout the Union 

 south of the Orange River and ample as are my series from certain 

 points, those points are comparatively few and widely separated as 

 may be seen from the accompanying list: 



N. W. area: Springbok, Sts?nkopf, Prieska (Sodium) Van 

 Rhynsdorp. 



S.W. area: Malmesbury, Stellenbosch, Elsenberg, Simondium, 

 Groot Drakenstein. 



Middle area: Victoria West, Nobelsfontein, Three Sisters, 

 Beaufort West, Krantsvogelkuil, Montagu, Willowmore. 



S.E. area: Peddie, Alicedale, Coeney. 



Upon the whole each series is fairly representative of the average 

 condition of the particular community each illustrates. This being 

 so it is remarkable that in the Malmesbury series only are there 

 workers that attain the full dimensions given by Sjostedt for 

 H. aurmllii. Quite a number of these workers have a head width 

 of 3.8 mm. In only a few of the remaining series is there an 

 occasional worker with a head ^vidth of 3.5 nrni. Apart from 

 their wide heads the workers from the Malmesbury district are 

 also more in agreement with Latrielle's type as regards the colour 

 of the head and the striking distinctness of the pseudo ocelli. So 

 much is this the case that one feels sure the type locality of viator 

 must be that neighbourhood or somewhere in the country interven- 

 ing between there and Cape Tovm of a similar, sandy treeless, 

 nature. 



The points upon which Sjostedt distinguished aurivillii from 

 viator may be tabulated as follows:
