Hob. Africa (the Cape of Good Hope ; Port Natal ; the Gambia ; 

 Sierra Leone; Egypt; Algeria). 



This species has been obtained from all the above localities ; 

 on examining a large number of specimens, it proves to be an 

 insect subject to much variety. The most highly coloured indi- 

 viduals are from the Gambia : some specimens have the head 

 and thorax ferruginous ; there are two black s])Ots above the tri- 

 dentate spot on the face, and another which encloses the 

 ocelli ; the thorax has a black stain before the scutellura and 

 another at the base of the metathorax, otherwise entirely ferru- 

 ginous and yellow. Specimens from the Cape have usually less 

 of the yellow and ferruginous colouring, and the scutellum is 

 sometimes nearly or entirely black. 



12. Philanthus formosus. B.M.

 gination of the eyes, yellow; a minute black spot above the 

 clypeus, and another above the insertion of each antenna ; the 

 mandibles and base of the flagellum ferruginous; the hinder 

 margin of the vertex and cheeks ferruginous. Thorax : the col- 

 lar with a narrow yellowish-white line, sometimes a yellow inter- 

 rupted line on the post-scutellum ; wings fuscous, palest at the 

 hinder margin of the posterior pair ; the nervures, tegulse and 

 legs ferruginous ; the coxae and sometimes the base of the femora 

 black. Abdomen : the first segment, the apical margins of the 

 four following, and the two apical segments entirely, ferrugi- 

 nous ; the second segment has on each side at its base an oblong 

 whitish macula pointed w ithin ; the third, fourth and fifth seg- 

 ments have a narrow undulating white marginal hne.
