Type $ ill tlie Britisli Museum. 



The very characteristic markings of this pretty little Baris readily dis- 

 tiiig-uish it from any other described African species of the genus. I 

 have seen three females only, which were bred by Mr. King in July, 

 1910, from larvts found boring in the stems of Portulaca oleracea, an 

 edible plant used for salads. The species will be figured in the forth- 

 coming Report of the Wellcome Research Laboratories.
