Antennae: XV. jointed; joint III. shorter than II, joint IV. 

 somewhat globose, larger and longer than V., longer and much 

 wider than III. 



Pronotum: almost semilunar, sides tapering to somewhat wide 

 hind margin, as wide as the head across eyes, long'er than iialf 

 Its width. ( 15 :25 ) . Meso- and metanotum : with broadly incur- 

 vate hind marigins. 



Wings: hyaline, fuliginous. C. and R. black. M. and Cu. 

 weak hut firmly defined ; M. extending close to and parallel with 

 Cn. and tending to supplant Cu., sending curved offsets to hind 

 margin of the mng. 



Headwidth across eyes 1.42; between 1.10. Body with head 

 extended 9.5 ; body with wings 15 ; forewing with stump 12.5, 

 without 12 X 3; span 25.5. 



Nasutu: — ^Head dark chocolate brown, apical third of nasum 

 pallid, reddish-yellow. Antennae ochraceous. Thorax and ab- 

 dominal tergites brown; cox.ie and femora pale brown, tibiae 

 and tarsi pallid. 



Nasum: acicular — Head: from above, elongate turbinate, 

 plainly but not greatly constricted towards the base of the 

 nasum ; from the side, the straight profile of the nasum Con- 

 tinues on to the vertex so that the arched hinder part of the 

 head appears quite short. Nasum plainly longer than head- 

 height; hind margin of antennal foveola at half the headlengtb. 

 Mandibles with a very distinct conical spine situated towards 

 their apex; when seen in a natural position, from the side, this 

 spine appears to be two-fifths the length of the mandible. 



Antennae: XL, XII. and XIII. jointed; joint III. always al 

 most twice the length of II. (9:5 or 8:5). When XI. jointed, 

 IV. loag and constricted, as long as I. (10:10) ; when XII., joint 

 IV. a little longer than II, (6:5) and a little shorter than V. 

 (r>:7) ; when XIII., joint IV. a little shorter than II. (4:5) and 

 plainly shorter than V. (4:6). 



Pronotum : cephalic edge entire. 



Head, width 0:S9: length 1-58 to 1-62; height 0-57 to 0:63. 



Workers'- — Heads brownish, dorsal tergites paler grey brown: 

 legs pallid ; the bright white median line of the head is extended 

 over thorax and abdomen, fading out more or less caudally. 

 Clypeus half as long as wide. Cephalic edge of pronotum nar- 

 rowly emarginate. 



There are two worker castes differing but slightly in size 

 The larger have XV. jointed antennae, the lesser, XIV. jointfed 

 antenna\ When XV., joint III. minute: V. smaller than IV., 

 .VI. globose; when XIV., joint III. is larger than II. and IV., 

 obviously a compound (III. plus IV. of the XV. expression). 



Locality: Malmesbury, Cape. (R. Birch, Oct. 1920). The 

 series upon which this description is based was found livinj; 

 in a mound of Hamiiermes sp.
