TWO NEW WATER BUGS FROM THE WESTERN U. S. A. (NEPIDAE AND NOTONECTIDAE)
Keyword(s):
In the routine work of sorting and determining Aquatic Hemiptera from the western United States, I was quite surprised recently to discover two new species in genera which I supposed were fully known. In a lot consisting of 110 Ranatra tahen by Doctor R. H. Beamer and his parties on the Biological Survey trips into the southwestern United States during the last two or three years I found one specimen of a very distinct and new species.
