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

 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. kliif/ii. 

 First tergite sparsely punctured. 

 Sixth tergite closely rugosely punc- 

 tured. 



S. persimilis. 



First tergite closely punctured. 

 Sixth tergite sparsely and more 

 finely punctured. 



Hab. 30 miles from Magadi Junction, British East Africa 

 {F. G. Hamilton), April 1912. 



Subfamily CiiABRONiy.E. 



Rhopalum ornatipes, sp. n. 



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

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

 intermediisque, trochanteribus posticis, tibiis posticis dimidio 

 basali, metatarsisque posticis flavis ; alis hyalinis, iridesceutibus, 

 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 ; pronotum 

 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
