On three species of Hymenoptera from East Africa. 



BY WILLIAM J. FOX. 



The three species of Hymenoptera mentioned herein represent 

 a portion of a small collection of insects collected by Dr. Wm. 

 L. Abbott, on Mt. Kilima Njaro, E. Africa, at an elevation of 

 4000 feet, and presented by him to the American Entomological 

 Society. 



Sphex Abbotii n. sp. $. Black; head and thorax clothed with long 

 black pubescence, which is short and rather bristly on the dorsulum, and 

 intermingled with griseous on cheeks and sides of the thorax; clypeus 

 feebly and sparsely punctured, with a shallow depression centrally, before 

 the anterior margin with a strong transverse impression, the anterior mar- 

 gin, medially incurved, with a slight tooth or process on each side of the 

 incurvation of inner eye; margin not altogether parallel as they begin to 

 converge at a point opposite the ocelli; labrum acutely carinated on its 

 anterior portion, the carina projecting sharply over its margin; a distinct 

 impression extends from lower ocellus to between the base of antenna;; 

 the ocelli placed in a V-shaped furrow; thorax on the sides shining, finely 

 punctured, the dorsulum very finely rugose; scutellum with a strong me- 

 dial impression; metathorax above coriaceous, impunctate, with a distinct 

 longitudinal furrow, which is broader and deeper at apex, on the sides the 

 metathorax is finely punctured; stigma furrow curved, foveolate; wings 

 brownish black, with a strong violaceous reflection, first recurrent nervure 

 received by the second submarginal cell before its apex, the second being 

 received by the third submarginal cell between its base and middle, and 

 is strongly bent towards the apex of the wing, third submarginal cell much 

 narrower above than beneath; the anterior tarsi with a row of long spines 

 posteriorly, the first joint with three spines in the middle of its anterior 

 margin; abdomen shining, the venter with a few long black hairs. Length 

 30 mm. 



One specimen. 



Belonogaster rufipennis De Geer. 

 One specimen. 



Xylocopa nigrita? Fab. 



One specimen, which agrees tolerably well with the short diag- 

 nosis given by Smith (Tr. Ent. Soc. Lond., 1874, p. 261), but 

 it has the anterior and posterior femora entirely black, and is 12 

 mm. longer. Not having specimens of nigrita, I am in some 

 doubt as to the identity of this specimen. The length is 40 mm.
