Dr. Aitchison's specimens are, I think, evidently referable to Walker's Caphaloxys 

 qua&rvmacula (Cat. Horn. i. p. 238), although they are a little larger than the type, which 

 is from North India. According to the British Museum collection, C. quadrimacula is 

 only a synonym of Cicadatra qu&rula, Pallas. 



HYMENOPTERA. 



By W. F. Kirby, 



Assistant in the Zoological Department, British Museum. 



The determination of this small collection has been attended with considerable 

 difficulty, owing partly to the specimens having been preserved in spirit (a method 

 peculiarly unfitted for hairy insects such as bees) and partly to many of the allied species 

 described from Eastern Europe and Western Asia being unrepresented in the British 

 Museum. 



It has therefore been impossible to determine some of the species in the collection 

 with certainty, owing to the unsatisfactory condition of the specimens ; and in numerous 

 other cases the determinations must remain somewhat doubtful for the present until 

 the insects can be verified by comparison with actual specimens of those which they 

 are believed to represent. 



Most of the species exhibit well-marked African affinities, several being apparently 

 identical with Algerian insects. Others are allied to insects collected by Fedchenko in 

 Turkestan ; but the proportion is smaller than might have been expected. 



I have not ventured to describe more than one or two well-marked forms as new.
