 Argutor brevicornis Kirby, Fauna Bor. Am. 4, 31. 



Stereocerus similis Kirby, Fauna Bor. Am. 4, 34, is possibly merely a Pterosti- 

 chus, but from the absence of dorsal punctures it may be an Amara; the figure 

 resembles much Myas foveatus Lee, but the palpi do not at all agree in form with 

 that genus.
