238 Mr. R. E. Turner on Fossorial Hymenoptera. 



Zambesi; Nyasaland, S.W. of Lake Chilwa (S. A. Neave), 

 January 1914. 



The range apparently overlaps that of H. anchietce in 

 N. Rhodesia and Nyasaland. 



Very nearly related to the three above forms, but differing 

 in having the clvpeus a little less strougly emarginate and 

 the hiud tibia? less strongly serrate, is Hemipepsis insignia, 

 Sm., the locality for which is given as W. Africa. 



Hemipepsis guadraticollis, sp. n. 



5 . Nigra ; capite, antennis, pronoto pedibusque fulvis ; tergitis 

 2-6 flavis, apice anguste ferrugineo-marginatis, 2-4 in medio 

 longitudinaliter ferrugineo-fasciatis ; sternitis brunneo-ferru- 

 giueis ; alis fusco-violaceis. 



cT . Femina? similis. 



Long., 2 1- mm., c? 9 mm. 



? . Clypeus widely and very shallowly emarginate at the 

 apex ; labrum broadly rounded, not incised. Interantennal 

 prominence well developed, rounded at the apex and divided 

 by a longitudinal sulcus which extends to the anterior 

 ocellus. Antennae stout and rather short; eyes separated 

 on the vertex by a distance not quite equal to the combined 

 length of the second and third joints of the flagellum ; the 

 posterior ocelli nearer to each other than to the eyes. 

 Anterior margin of the pronotum transverse, the angles not 

 rounded, the sides parallel. Median segment without 

 lateral tubercles, very finely and closely transversely 

 striated, sparsely clothed with black hairs ; the posterior 

 slope steep, but not vertical, not sharply divided from the 

 dorsal surface, which is distinctly convex. Abdomen sub- 

 opaque, sparsely covered with delicate pubescence ; the 

 ventral surface more shining and sparsely punctured. Hind 

 tibia? feebly serrate, without spines. Cubitus of hind wing 

 originating well before the transverse median nervure. 



<$ . Antennae not very stout, rather short, not longer than 

 the head, thorax, and median segment combined ; second 

 and third joints of the flagellum subequal. Apical sternite 

 very broadly rounded, the penultimate with a short longi- 

 tudinal carina ending in a short spine on each side. 



Hah. Bweva, Uganda (C. G. Gowdey), May 1913, 1 ?; 

 Valley of Kafu River, Unyoro, 3400 ft. (£. A. Neave), 

 December 1911,2 <$ $. 



This little species is closely related to iodopfera, Stal, but 

 differs in the much smaller size, the colour of the abdomen,
