Metallic-green, clothed with whitish down. Head black* 

 Antennae tawny, nearly fusiform, shorter than the head ; arista very 

 short. Thorax with a purple dorsal stripe, and with a large purple 

 spot on each side. Scutellum very hairy, obconical, very large, ex- 

 tending over half the length of the abdomen, armed at the tip with 

 two long stout teeth, and on each side with three small teeth. Ab- 

 domen deep black, round, much broader, but hardly longer, than 

 the thorax, blue on each side ; hind borders of the segments green ; 

 under side dull tawny. Legs black, stout, pubescent ; femora 

 tawny towards the tips. Wings gray, darkest along the costa as far 

 as the stigma, which is blackish ; veins black ; first branch of the 

 cubital vein nearly straight, moderately long, ending at a little be- 

 fore half the length between the radial and the second branch, which 

 ends very little in front of the tip of the wing ; three complete 

 externo-medial veins; discal areolet hexagonal. Length of the 

 body 2 lines ; of the wings 4 lines. 



This insect, like most of the exotic species, differs in structure 

 from the typical C. ephippium, and will probably be soon ranked as 

 another genus.
