? . Extremely near to S. klugii, Sm. (£. apicalis, Klug), 

 of which I formerly considered it a variety (see Ann. & Mag. 

 Nat. Hist. (8) xvii. p. 444, 1916). But I have since had 

 the opportunity of comparing it with a female of klugii in 

 the collection of the Rev. F. D. Morice, and find the following 

 distinctions in addition to colour : — 



S. klugii. 

 First tergite sparsely punctured. 

 Sixth termite closely rugosely punc- 

 tured. 



S. persimilis. 



First tergite closely punctured. 

 Sixth tergite sparsely and more 

 riuely punctured. 



llab. 30 miles from Magadi Junction, British East Africa 

 (F. G. Hamilton), April 1912. 



Subfamily Crabronixju. 



Rhopalum ornatipes, sp. n. 



§ . Nigra ; mandibulis, apice excepto, clypeo, scapo, flagello 

 dimidio basali subtus, pronoto, scutello, tegulis, pedibus anticis 

 intermediisque, trochanteribus posticis, tibiis posticis dimidio 

 basali, metatarsisq'ue posticis flavisj alis byalinis, iridescentibus, 

 venis fuscis. 



Long. 4 mm. 



? . Eyes separated at the base of the clypeus by a distance 

 equal to about one-quarter of the length of the scape, the 

 facets much larger in front than on the side ; clypeus short 

 and broad, clothed with delicate white pubescence. Head 

 smooth and shining, an indistinct groove from the posterior 

 ocelli not quite reaching the eyes ; temples about half as 

 broad as the eyes. Thorax smooth and shining; pronotuni 

 transverse; median segment almost smooth, with a well- 

 marked median sulcus. First tergite very slightly longer 

 than the second, not much swollen at the apex ; second. 

 tergite broadened from the base, nearly half as long again
