" $ . A small species, of a somewhat stumpy build. Particu- 

 larly noticeable on the head are the small and but slightly projecting 

 eyes, which are separated from the base of the mandibles- by a 

 distance about equal to the thickness of the scape. The mandibles 

 are plainly smaller than in affinis. The antennae are long, the 

 scape shorter than the first 5 joints of the flagellum, or about as long 

 as one-third of the latter. Tborax stout, petiole as in affinis. 

 There are some erect hairs on the pronotum ; on the mesonotum 

 and scutellum only a long, adpressed pubescence, which is hardly 

 glossy and does not conceal the chitin. Colour brownish yellow, 

 head excepting the mandibles dark brown ; on the mesonotum in 

 front there is a short median band of darker colour, and also two 

 lateral bands which do not reach the anterior margin ; the femora 

 and petiole brown ; the margins of the abdominal segments 

 brownish. Wings noticeably short, glassy and with brown 

 nervures ; the transverse nervure joins the middle of the root of the 

 cubital. The genital organs are constructed much as in affinis, but 

 the outer parameres seen from above are markedly broad, not 

 excised at all laterally. Length, 20-21 mm. ; head and thorax, 

 8 mm. ; width of thorax, 4 mm. ; anterior wings, 12-5 mm." 



$ 8"5 mm. This worker is deceptively like that of affinis, 

 differing only in its smaller size in the major forms, and in 

 having the petiole shorter and wider behind than in that species. 



The type species has not been recorded from this region, but 

 I quote the description for the purpose of making clear the com- 

 parisons in the account of the following variety, which was 

 originally found at Salisbury, S. Rhodesia.

 $ . 19 mm. Width of thorax 4 mm. This differs from the type in 

 having a stouter and darker thorax, castaneous brown, and the nearly 

 black head ; the sides of the thorax are lighter ; the longitudinal 

 lateral fascia and the spots on the anterior part of the mesonotum 

 less clearly defined, on account of the darker ground-colour. 



£ max. 8 - 5 mm. Head, 2-8 mm. long x 23 mm. wide. The 

 colour is a little darker than the type species, and the puncturation
