Acucephalus albifrons (Linnaeus).
Taken at Barber Point close to the Camp where timothy and other grasses furnish an abundant support. This species has been found to feed on the crown of timothy and it occurs commonly so far below the surface that it is seldom taken in ordinary sweep ing. in cultivated fields it assumes very considerable importance. Cranberry Lake, Aug. 1, 1917; Aug. 6 and 9, 1920. Wanakena (French Camp), Aug. 12, 1920.
Xestocephalus pulicarius Van Duzee. Wanakena (Bean Pond), Aug. 12, 1920. Xestocephalus nigrifrons Osborn.
Wanakena (French Camp), Aug. 12, 1920. Parabolocratus viridis (Uhler).
Wanakena, Aug. 12, 1920.
Parabolocratus major Osborn.
This species has been taken elsewhere upon Calaniagrostie coma densis and as this grass occurs in the swamp meadows where it has generally been taken, it is probable that this has furnished its food in this locality. None have been taken except in the marsh meadows or similar locations. Cranberry Lake and Barber Point, July 3, 1.919 (adult) ; June 9, 1920 (nymph). Wanakena. Aug. 1-7, 1917; July 15, 1920. Silver Brook, .July 22, 1920 (adult).
Mesamia vitellina (Pitch).
This species has been one of the most frequent captures of the less common forms and has been taken in sweeping maple and other undergrowth so that it has seemed probable that maple may be at least one of its principal foodplants. Nymphs associated with these adults, and which resemble very closely those of Thaw notettex kenalicolti, were thought to be the young of this species; and it is possible that the nymphs of the two forms are quite similar. One such nymph was kept in a cage and fed on maple leaves for about four weeks but it did not mature. Wanakena, Aug. 1-7, 1917; Aug. 12, 1920. Ranger School, July 15, 1920 (adult). Grasse River, July 22, 1920 (adult). Plains, Aug. 3, 1920.
Scaphoideus auronitens Provancher. Nymphs, Plains, Aug. 3, 1920. Scaphoideus scalaris Van Duzee.
This is a very common species west but occurs quite rarely in this region, only one record having been made. Cranberry Ittke,
Aug. 1, 1917.
Scaphoideus lobatus Van Duzee.
Usually taken on grasses in open wood. Cranberry Lake, Aug. 1, 1917.
Scaphoideus productus Osborn.
This appears to he about the most common species of the genus for this region, much more plentiful, if we can judge by our col lection, than the following species which is the most abundant one fm• the country at large. Cranberry Lake and Barber Point. July 25, 28, 1917; Sept. 15, 1919. Wanakena, Aug. 1-7, 1917; Aug. 12, 1920; (nymphs) July 15 and Aug. 3, 1920. Bear Moun tain, Aug. 15, 1920.
Scaphoideus immistus (Say). • Taken very rarely, although it is by far the most common and generally distributed species of the genus in the U. S. It is taken On willows and grape and these are probably to be included among its host plants. Cranberry Lake, Aug. 5 and 10, 1917.
Platymetopius acutus (Say).
A common and very widely distributed species equally at home in open fields or forest, on low land or hill top, evidently having a great latitude of food plants. It is perhaps the most universally distributed of any species of leaf-hopper taken in this region, appearing in almost every sweeping for almost every habitat studied. Cranberry Lake, Barber Point, July and Aug., 1920. Wanakena, Aug. 12, 1920.
Platymetopius acutus (Say) var. cinnamomeus Osborn.
This variety appears to grade into the typical form, but nymphs which have been reared to this form seem to have a fairly distinct. marking and, as such nymphs are most abundant in boggy loca tions and seldom taken in higher altitudes, it would appear that there has been a fairly distinct separation of the form from the common stock. Cranberry Lake and Barber Point, July and Ang., 1920. Wanakena, Aug. 12, 1920.
Platymetopius cnprescens Osborn.
Found in open grass covered places, usually the drier spots. Wanakena (Plains), Aug. 3, 1.920.
Platymetopius magdalensis Provaneher.
Found in boggy places, especially in the blueberry association. Cranberry Lake, Aug. 10, 11, 1920. Wanakena, Aug. 12, 1920.
