This species varies somewhat in the breadth of its outline, and in 

 the distinctness of the punctation upon the pronotum and scutellum. 

 It is the largest thus far discovered in the United States, and is the 

 only one of our species which agrees with the descriptions of Ger- 

 mar and Herrich-Schaeffer, above cited. It is the same as a speci- 

 men of Galgupha atra Amyot and Serville, from Mexico, kindly sent 

 to me by Dr. Signoret. Mr. Scudder, while in Paris, obliged me by 

 comparing my specimens with the types of C. unicolor Palisot 

 Beauvois in the collection of Dr. Signoret; the result of which was 

 that both gentlemen coincided in considering them to be different 

 species. As the name unicolor is thus seen to have been previously 

 employed by Beauvois, it becomes necessary to adopt a later one. 

 The next name given, however, that of C. lielopioides by Wolff, is 

 also preoccupied, and thus we are carried to the latest, that of Amyot 

 and Serville, as the only one available for this species. Specimens 

 differ considerably in size and density of punctuation, and some are 

 much more dark and dull than others. Generally, they are highly 

 polished and have a greenish-brassy tmge. 



The genus Galgupha erected for it by Amyot and Serville can not 

 stand, as the characters derived from the size of the scutellum are 

 neither separative nor permanent. 



2. C. nitiduloides.
