[The two pairs of yellow spots on the abdomen of the 

 female of this species produce with the general colouring 

 and shape a remarkable superficial resemblance to the 

 female of the excessively abundant Scolia quadrvpitnctata. 

 When at rest upon a flower the insects could only be dis- 

 tinguished by careful observation. The resemblance is 

 doubtless synaposematic, like that which obtains between 

 the South African Scolia alaris and the Diploptera. (Trans. 

 Ent. Soc. Lond., 1902, pp 527-529.) Mr. A. H. Hamm
