Some New and Little-known Heteroptera from the 

 Western United States. 



By J. R. DE LA TORRE BUENO, White Plains, N. Y. 



When Professor J. M. Aldrich made his Western trip last 

 year to look for Packard's Ephydra calif ornica, he most kind- 

 ly offered to endeavor to get me some specimens of Uhler's 

 Gerris robust us, originally described from Clear Lake, Cali- 

 fornia. He was successful not only in his own particular 

 quest, but also in securing the long-lost Gerris, and together 

 with that a number of land forms which he most obligingly 

 permitted me to work up for him. They follow with appro- 

 priate comment. The species, it should be noted, are typically 

 Western with two exceptions, viz: Harmostes reflexulus Say 

 and Brochymena ^-pustulata Fabr. 



Notonecta indica Linne. 



A long series from Garfield, Utah, and Lake Elsinore, Cali- 

 fornia, received through Prof. J. F. Abbott, who has the 

 Corixas, and some labelled Smaller Soda Lake, Nevada. 

 These are very interesting habitats, as the lakes are salt or 

 alkaline, thus tending to show that Notonecta is not neces- 

 sarily a fresh water insect. 



Acanthia xanthochila Fieb. 



Lake Elsinore, California; Soda Lakes, near Hazen, Pyra- 

 mid Lake, and Winnemucca Lake, Nevada; Garfield, Utah. 



This is a most widespread species, and is practically Holarc- 

 tic in its distribution. The twelve specimens taken at these 

 various places are typical. 



Acanthia coriacea Uhler. 



Brigham, Utah. One specimen. 



Acanthia polita Uhler. 



Garfield, Utah. One example. 



Acanthia sp. (near saltatoria L.). 



Highland Springs Lake. Three specimens.
