Hah. Ecuador. 



Head dark blue, opaque, rather deeply depressed between the 

 eyes ; this depression, as well as the clypeus, rugose ; rest of the sur- 

 face remotely but distinctly punctured. Labrum, palpi, and the 

 antennae fulvous ; last seven joints of the latter distinctly thickened, 

 and extending to half the length of the body. Thorax three times as 

 broad as long, very convex, of a greenish leaden colour, the sides 

 finely margined with metallic green ; surface with a few obsolete 

 depressions near the base, very closeh' and rather finely punctured. 

 Scutellum broader than long, its apex broadly rounded, extremely 

 finely punctured. Elytra very dark violaceous blue, not wider than 

 the thorax, the shoulders rather prominent, more finely punctured 

 than the thorax, the punctures placed in rather regular rows, and 

 distinct to the apex. Underside black, abdomen fulvous.

Collection Jacoby. 



From the three other species described by Mr. Baly the present 

 one is distinguished by its coloration in connexion with its size. 



In Dr. Chapuis's remarks on this genus, I find the eyes men- 

 tioned as being separated by a narrow space only ; this is a mistake, 

 as, on the contrary, they are very widely apart. 



Genus Noda, Chapuis. 



5. Noda unicostata, sp. nov. 



Oblong-ovate, moderately convex. Below greenish blue ; above 

 metallic aureous, five baspl joints of antennae fulvous ; thorax and 

 elytra finely punctured, the latter with a lateral costa posteriorly. 



Var. Entirely metallic green above.
