CELETOCNEMA. 395 



the author, it is separated by the thorax having the sides straighter and by its generally 

 broader shape ; Mr. Baly has, however, placed two other specimens with the type which 

 I absolutely do not distinguish from C. divergens, and I believe, moreover, that this 

 shape of the sides of the thorax will be found to vary in different specimens. I must 

 add also that the colour of C. mexicana is not " cuprea," as given in the diagnosis, but 

 greenish-aeneous, and the same as that of C. divergens and most of the species of the 

 genus. 



2. Chaetocnema divergens. 



Chcetocnema divergens, Baly, Trans. Ent. Soc. 1877, p. 301 \ 



Hab. Mexico, Campeche 1 (coll Baly) ; British Honduras, Rio Hondo (Blancaneaux) ; 

 Guatemala, near the city (Salvin), San Geronimo (Champion) ; Nicaragua, Chontales 

 (Janson) ; Panama, Volcan de Chiriqui (Champion). 



I must refer all the specimens from the above localities to this species, with the type 

 of which they agree perfectly, although slight variations in colour and even shape are 

 not wanting ; as remarked above, I do not think that the insect is specifically distinct 

 from C. mexicana. 



3. Chaetocnema gravida. 



Chcetocnema gravida, Baly, Trans. Ent. Soc. 1877, p. 302 \ 

 Hab. Mexico, Teapa 1 . 



A broadly ovate species, in which the head is distinctly punctured. I cannot call the 

 colour of the upper surface " cuprea," as given in the diagnosis, as the type before me 

 is of a very obscure blackish-aeneous colour, the thorax only showing a very slight 

 greenish tint. 



4. Chaetocnema sallsei. 



Chcetocnema sallei, Baly, Trans. Ent. Soc. 1877, p. 302 \ 

 Hab. Mexico K 



The head and thorax in this species are much more closely punctured than in 

 C. gravida, and the general shape is less robust and convex, the elytra having even a 

 subdepressed appearance. I am unable to distinguish this species from C. denticulata, 

 11%. 



5. Chaetocnema discoidalis. 



Chcetocnema mexicana, Harold, Coleopt. Heffce, 1879, p. 231 \ 

 Hab. Mexico 1 . 



On account of the name of " mexicana " having already been employed by Mr. Baly 

 for another species of the genus I have been obliged to rename that of Von Harold.
