CICADELLIDAE Agallia novella (Say).
Taken especially in undergrowth of trails and along tote roads and probably feeds on quite a varied list of food plants. State Forest Camp, Barber Point, July 3, 1920. Adults, collected at the Plains, Aug. 3, 1920.
Agallia 4=punctata Provancher.
Much less common than the preceding species and probably somewhat limited as to food plants, occurring in woods near the trails. It has been recorded as common on cultivated crops but may be considered of practically no economic importance for this region. State Forest Camp, Barber Point (adults), July 3, 1920. Wanakena, Aug. 12, 1920. Plains, Aug. 3, 1920.
Agallia oculata Van Duzee.
A single specimen taken here appears to be distinctly identical with the form described as oculata, the common range of the species being south and into the tropical parts of the continent.
Agallia sanguinolenta (Provancher).
A common species where clover or other legumes occur. In other localities this species is of very distinct economic importance as it attacks cultivated crops, but in the Cranberry Lake region it is only found in the trails or tote roads where introduced grasses or clover furnish it a good basis. Most of the individuals cap tured were rather small in size compared with the forms taken in other localities. Cranberry Lake in July and Aug., 1920. Plains, Aug. 3, 1920. Wanakena, Aug. 12, 1920.
Idiocerus amabilis Ball (Plate I, Fig. c.) Quite common on willows, especially along Sucker Brook and in the East Flow on willows which overhang the water: Newly transformed adults are a brilliant yellow-green with golden luster. Head and pronotum brown with lighter marking; vertex solid green at sides, brown on central part except narrow whitish median stripe. The face for the upper part is like the vertex below the ocelli green. The antennae light green at base and the bristles dark ; underneath, except for the mesothorax, brilliant green. The tarsi whitish with the spurs and claws black. Cran berry Lake, July 18-4 1920. Wanakena, Ranger School, July 15 and Aug. 12, 1920.
Idiocerus formosus Ball.
Taken along stream and probably feeds on willows. Cranberry Lake, Aug. 3, 1920.
Idiocerus pallidus Fitch.
Common on -various species of willow and one of the most abundant forms upon this plart. It is apparently Dot capable of living on other food plants so that its economic importance is re stricted to the value of the willow. State Forest Camp, July 2. Grasse River, July 22, 1920. Wanakena, Aug. 12, 1920.
Idiocerus suturalis Fitch (Plate I, Figs. a and b).
Forest Camp, July 2, 1920. Grasse River, July 22, 1920. Wanakena, July 29 and Aug. 12, 1920.
ldiocerus alternates Fitch.
Common on poplars and willows and one of the more abundant forms of the genus. This occurs over wide territory and in a num ber of more or less distinct varieties. State Forest Camp, July 5, 1920. Grasse River, July 22, 1920.
Idiocerus subnitens Sanders and Delong.
Numerous specimens, taken at Barber Point on willow, 1917, 1919 and 1920. A few specimens were also collected on poplar, but ,Salix seems to be the preferred food plant. The insect was de scribed from Wisconsin.
ldiocerus lachrymalis Fitch.
The nymphs of this species were quite abundant on aspen early in July. The adults appear later in the season so that the species may be counted fairly common and as it is most abundant upon the aspen its injury may be considered as limited to the latter tree. The egg punctures in the twigs and smaller branches occasion large swellings and distortions and no doubt weaken the limbs so that they are easily broken. State Forest Camp, July 2, 1920. Grasse River, July 22, 1920.
Idiocerus provancheri Van Duzee.
While this species has been taken on plants away from bogs in other regions, all of our specimens here have been from bog plants and this seems to be its restricted habitat, the special plants on which it occurs being Viburnum or Cassandra. This species is not abundant but a number of specimens have been taken at different points. State Forest Camp, July 5, 1920. Grasse River, July 22, 1920. Plains, Aug. 3, 1920.
