abdomen is wider, the 1st segment being only a trifle longer than wide, 

 and only twice as long as the 2nd segment, whereas in the type species 

 and in var. Arnoldi, it is at least one-quarter longer than wide, and 

 three times longer than the 2nd segment. The basal neck-like portion 

 of the 1st segment is also shorter. 



This variety has a r „very strong cockroachy odour, similar to Pachy- 

 condyla soror. Eedbank, S. Rhod., Victoria Falls.

The examples from the Victoria Falls are even larger, 8-8*3 mm., and 

 have the excision of the clypeus almost as deep as in var. Arnoldi, but 

 these differences are hardly sufficient to justify their separation as a 

 variety distinct from Foreli.

" $ . 5 - 5-7 mm. Reddish brown, with brighter brownish yellow 

 abdomen. The whitish, stumpy, pilose hairs are more abundant and 

 longer than in the type species ; the hairs are also thicker. Headless 

 wide in front. First joint of petiole with much longer peduncle, some- 

 what like Robechii, Emery, and laticejps, Forel, and with smaller nodes. 

 The head is also arcuately and transversely striate behind (in the type 

 species somewhat divergent and longitudinally striate), and not so 

 wide."

" Differs from the type by its darker brown colour, but more 

 especially by the narrower head which is hardly widened in front, and 

 has the sides more convex. The 1st joint of the petiole has also a 

 longer peduncle, and the yellowish hairs are also longer, although not 

 so blunt as in hirsutus. The head is narrower than in hirsutus. The 

 <$ is 4 - 5 mm. long. Its head is short behind the eyes, wider than 

 long, the hind margin broad and convex. Wings glassy. Mesonotum 

 strongly gibbous in front. First joint of petiole with long peduncle."
