This species is erroneously described as possessing “‘ extremely finely punctate-striate

Aphthona pallipes (p. 364). 
To the localities given, add :—Mexioo, Chilpancingo, Amula, Orizaba (H. H. Smith).

I refer a very large number of specimens from the above localities to this species. 
The antenne in most of the Mexican specimens are entirely flavous; some examples, 
however, have the apical joints stained with fuscous (as in the type). The legs are 
flavous, the posterior femora black. 
8 (s). Aphthona pectoralis. 
Fulvous; the head almost, the thorax entirely, impunctate, the latter strongly transverse; elytra metallic

Head fulvous, with a few fine punctures on the vertex, the frontal tubercles and the carina small but distinct ; 
antenne half the length of the body, fulvous, the terminal joints sometimes slightly darker, the third and
