 pubescent, tawny ferruginous, opaque j j^rothorax small, not 

 broad at the base, minutely punctured j scutellum triangular ;

This species is allied to the following, but, infer alia, lias a 

 broader and less elliptic outline, and is much less convex.

 and, with the tibiae, ferruginous. Length A\ lines. 



Amarygmus suturalis.

This and the two above are among the very few striated spe- 

 cies of the genus; and of the striated species they are the most 

 Hpnvcx and elliptical in outline. Besides the difference of
