Phlepsius maculellus Osborn.
This species which has been very rarely observed, was described from a single male specimen taken in A single specimen was taken in 1917 (Barber Point) and a few specimens the present season, Barber Point, Aug, 11, 1920, appear to be all that have been collected. It is restricted to boggy areas and lives on one of the fine grasses of the bog association. Barber Point, 1917; Aug. 11, 1920. Wanakena, Aug. 12, 1920.
Phlepsius irroratus (Say).
This species is a very common one throughout the country on cultivated grasses and in meadows generally, but appears to be rare in this region; the only specimens taken are from the Grasse River, July 22, 1920, where there was an invasion of blue grass and timothy.
Phlepsius apertus Van Duzee.
This species seems to replace the preceding one in the northern or woods region as it is found very plentiful in Maine in locations where irroralus would seem to be the natural member. It was taken along the tote-roads and in meadows and where these grasses have any value it may he considered of economic importance. Cran berry Lake, Sept. 15. 1917 ; Aug., 1920. Wanakeua, Aug. 12, 1920.
Phlepsius fulvidorsum (Fitch).
This is usually limited to the woodland associations but is taken in trails, roadways and on one occasion was taken at the Plains. Aug. 3, 1920, in a trail near open land but probably associated with nearby thickets. Barber Point, Aug. 1 a 'Id 1S, 1917, and July, 1920.
Phlepsius solidaginis (Walker).
In this region the species has been taken only in the higher stations but in association with sedges and wet land grasses. In general it is found in swampy or wet land associations. Barber Point, Aug. 5, 1920. Wanakena (French Camp), Aug. 12, 1920.
Thamnotettix kennicotti (Uhler).
Both young and adult in this form have been frequently taken and while not absolutely sure as to all nymphs it seems to be one of the common species of the region. Cranberry Lake, Aug. 1, 1917 ; Aug. and July 28, 1919 ; reared Aug. 8, 1920; nymph com mon, Aug. 10, 1920. Wanakena, Aug. 1-7, 1917 ; Aug. 12, 1920.
Thamnotettix cockerelli Ball.
Heretofore recorded for Colorado and Maine. Swept at road side probably front willow as its host plant in Maine was found to be rostrata. The species is new in New York Slate list. Wanakena, .'\ug. 12. 1920.
Only one locality, east from Barber Point, Aug. 11, 1920, is noted for this species and it is evidently quite rare. Its food plant is evidently the sweet gale as no other plant has been recog nized in connection with it.
This is a northern and western species and not heretofore recorded for New York State. It has been recognized as most abundant in the Rocky Mountains. It occurs especially in wood land on undergrowth and this is considered as its definite habitat. Cranberry Lake, Aug. 1, 1917. Wanakena, July 15, 1920. Grasse River, July 22, 1920.
This variety was described from Maine and has the same general association as the preceding species but differs particularly in the coloration. Aug. 1--7, 1917.
Thamnotettix waldanus This is an inhabitant of the deep woods and has been found only on undergrowth in a dense forest and must be considered as restricted to this association. It was taken Ang. 29, 1920, especially among ferns but where maple seedlings and some other plants were present and it was hard to be certain of food plant.
Differs from the typical form in lacking the tawny stripes on head and pronotum. Plains, Aug. 3, 1920.
