The Termites of South Africa 1 1 5 



SubuliteTmes hainesi &p. n. 



Nasutu : — Head chocolate brown, somewhat paler around mouth 

 and antennal loveolae; nasum; black from base to about two- 

 thirds of its length, from there to tip paler, s,uf(:used red 

 brown. Legs and tergites pallid yellow. Cephalic margin of 

 pronotum tinged with red brown. Head, from above, elongate 

 turbinate; from the side, nasum longish, decidedly attenuate, 

 dorsal profile straight, hind margin of antennal foveola before 

 half the length of the head. Antennae: XIV. jointed, joint III. 

 narrow, not longer than II. Cephalic edge of pronotum entire 

 and in a regtilar curve. Head, width 0.95 to 1.00; length 1.79 

 to 1.84; height 0.63. 



Worker: — Head dark brown. Antennae XV. jointed, joint 



III. shorter than II., Quite narrow, the shortest joint; joint 



IV. a little wider than V. but of the same length; VI. longer 

 than V. Cephalic edge of pronotum entire Clypeus longer than 

 half its width (7:10). Head width 1.10. ' 



Localities: Steinkopf, Wolfdoon, Kenhardt. (F. Thomsen, 



J. C. Faure). This species constructs a low mound which is 



usually half buried by wind-blown sand. 



Genus TenUIROSTRITERMES Holmgren (1912). 



This genus was erected by Holmgren as a sub-genus for the 

 reception of several North American species represented by 

 nasuti of one caste with a dumb-bell shaped head, attenuated 

 nasum, and the head profile longer in front of the depression 

 than behind it. Further, the nasuti differ essentially from others 

 herein mentioned in having a distinct apical spine upon the other- 

 wise atrophied mandible. I have before me a nest series of a 

 species that I 9an refer to no other geniis than Tenuirostritermes. 



Tenmrostritermes mallyi sp. n. 



Imago : — Small, black and very glabrous, wings ample hyaline 

 tinged with black. Head: quite black except for the white 

 ocelli and small triangular fontanelle; clypeus black, antennae 

 black with pale and somewhat sordid rings. Tergites of thorax 

 and abdomen black. Legs black except tips of tibiae and tarsi 

 which are yellow. Sternites of abdoanen black, somewhat pallid 

 in the middle. Conjunctiva creamy-white. 



Head : flatly arched, without ridge connecting ocelli ; 

 fontanelle minute but easily discernible, triangular fur-

 vate behind; as long or slightly longer than half its width 

 (12 X 6 and 13 x 7). Eyes: black, subcircular. Ocelli: small,
