No. 11. Amphiagrion sp.: The late Mrs. L.K. Gloyd studied Amphiagrion for many years. Rosser Garrison has told me that she had examined over 3000 specimens of the genus and was planning on describing the "mid-American" form (AZ to the Midwestern states) as A. mesonum. This name was in use as a manuscript name, and many workers during that time period therefore described Amphiagrion from the region as A. sp. Some workers today apparently consider Amphiagrion as a species with gradual clinal variation from east to west. The problem remains to be closed. Thanks to Rosser Garrison (Personal Communication, Sept. 1995) for discussing the issue with me. In their recent master work on the Zygoptera of North America, Westfall and May (1996) state: "There is evidence that populations from the midwest, southwest into Arizona, probably repesent a third species, but their status is as yet unclear. Amphiagrion not clearly assignable to either A. abbreviatum or A. saucium are known from: AZ, CO, IL, IN, IA, KS, MI, NE, NM, ND, OK, SD, WI."
No. 40. I have followed Garrison(1991) and Westfall & May (1996) by transferring Anomalagrion hastatum into the genus Ischnura as I. hastata (Say), 1839.
