There is a narrow middle line of white extendmg from the tip of the head to, the end of the abdomen, where it widens and nearly covers the tip. There is a broad stripe extending along the side from the eye back to near the tip of the abdomen and an indistinct narrow one from the inner margm of the eye broken by white spots, one on the hind edge of each abdominal segment; there.

In Iowa the nymphs were first found in small numbers on upland prairies the second week in June. They were full grown and probably somewhat later than the average as the adults had been taken durmg the first week of June and occurred in great numbers in watered pastures by the middle of the month. Tlie adults were abundant from that time on through the season, but nymphs were again found on July 11 about half grown and full grown by the latter part of July along with fresli-lookhig adults. Nearly full-gro\vn nymphs were agam seen on the 5th of September and later m the month they were becoming rare while the adults were stiU plentiful. The atlults probably survived some time after egg deposition, so that there is a contuuious occurrence of adults to be noted throughout all of the latter part of summer. Egg deposition probably occurs in early October, as dissected females showed no sig
