insect approximates very closely to Emery's description of decolor, 

 differing from that species only in the presence of erect hairs on the 

 clypeus and abdomen. 



S. Rhodesia, not rare; Natal. 



A very agile insect, with very erratic movements. The nest is 

 usually formed in sandy soil. The galleries containing the repletes 

 are rarely less than a foot below the surface of the ground.

Var. karrooensis, n. v. 



These differ from the type of the species in the longer head, al- 

 most one-quarter longer than wide in the smallest ^ ^, and in the 

 longer scape which extends beyond the occipital margin by a little 

 less than one-fourth of its length. The thorax is somewhat narrower 

 and more convex transversely, the mesonotum being nearly as long 

 as wide. The head is slightly shining all over. The repletes differ 

 from those of the type species only in the shining head, with rather 

 stronger sculpture ; the abdomen is also slightly shining. 



Q. These differ from the type species in the same way as the 

 repletes. The colour is a little paler on the head, and the ocelli are 

 larger. The joints of the flagellum are all relatively longer. Wings 

 hyaline, faintly tinged with yellow, nervures ochreous.

P. (sub-gen. Anoplolepis) deceptor, n. sp. 



Q. 2-7-r>'2 mm. Reddish ochreous, the flagellum somewhat fus- 

 cuous, the middle and hind pair of legs pale yellowish brown, the 

 scale of the petiole brownish ochreous, abdomen black, except the 

 1st and 2nd segments which are dirty yellow, the 2nd having also 

 its apical margin black. Pubescence adjacent, very short, yellowish 

 and inconspicuous, almost wanting on the head, thorax, legs and 

 antennae. A very few yellowish, erect pilose hairs on the clypeus 

 and apical margins of the abdominal segments. Head, thorax and 

 petiole dull, very closely, finely and evenly reticulate-punctate or 

 granulate. Abdomen rugulose and dull, except the last three segments 

 which are smooth and shining. 



Head subquadrate, about one-sixth longer than wide, the sides very 

 feebly convex, not wider behind than in front, the posterior margin 

 straight. Eyes large, placed a little behind the middle of the sides. 

 Ocelli distinct. Mandibles slightly shining, striate, aimed with 5 acute
