Hah. Cameroons (Conrad). 



The single male specimen which I received from Dr. Kraatz is 

 readily distinguished by the structure of the scutellum, in which it 

 nearly agrees with Aulacophora scutdlata Baly ; but in that species 

 the antennae are simple, the shape of the scutellum is ditferent, and 

 the abdomen is not flavous.
