﻿llomopicra of Cranhcrnj Lake Region 35 



Oncometopia lateralis (Fabricius). 



Tliis species has a very Avide range, oeeurrin.s; from Canada to 

 the southern U. S. and infesting a. great varietj^ of plants. It lives 

 in a great variety of habitats. At Cranberry Lake it was taken in 

 the Plains region of the low ground along streams and on the hill 

 tops, but oecnrred in greatest abundance at the " F)-ench Camp," 

 Wanakena (Aug. 12, nymphs and adults were taken in large num- 

 bers). These "were secured by sweeping grass and apparently the 

 species was feeding in this location although possibly they may 

 liave developed on herbaceous plants in the immediate vicinity.

Cicadella gothica (Signoret). 



Abundant in woods and along road-sides or trails on various

 vegetation, especially in the adult stage. Cranberry Lake, Aug. 

 10, 1917. Wanakena, Aug. 3, 1920. 



Graphocephala coccinea (Forst.).

Draeculacephala mollipes (Say). 



This very common and abundant species, w^hich ranges all the 

 way from Canada to Central America occurs on a variety of 

 grasses but usually in dry or moderately moist locations. In the 

 forest it is found along trails, tote-roads and streams. Cranberry

Draeculacephala manitobiana Ball. 



This species has been taken along with the preceding in swamp 

 meadows but it was the most abundant in the large swamp meadow 

 of the Grasse River where it occurred on Carex oJifiospernui which 

 (it would seem) must be the food plant for the young as well as
