Extract

Melanchroism and leucochroism occur in Notonecta shooterii Uhler. In collections containing fairly good series of this species there will be two color sorts; one, a nearly concolorous pale luteous, and the other, deeply pigmented with violet-black. In a lot of 37 specimens taken in Cochise County, Arizona on July 29, 1927 by the University of Kansas Entomological Expedition 11 specimens are dark and the others are pale. Of these 11 dark ones 9 are females and 2 are males, while of the 26 pale specimens the sex distribution is even, 13 males and 13 females. This lot was captured from one pool.
