and margins black; the black of the tip wide: 

 feet bright red: intermediate tihise black before: 

 posterior tibiae, with a black line before. 



OBSERVATIONS. 



This very beautiful species was found by Mr. 

 T. Peale in Florida, and was presented to me, 

 for the present plate, by the Prince of Musignano, 

 with whom I agree in the specific name here 

 adopted from Hubner. 



The striking contrast of the red and black 

 colours, and the beautiful brilliant vivid azure 

 blue, reflected from the spots of the abdomen, 

 anterior part of the thorax and the head, render 

 this a highly interesting insect.
