Biology of the Membracidae of the Cayuga Lake Basin 201 



station has yielded the largest number of specimens of T€la7nona unicolor 

 taken in the basin. 



Station P, the territory along the Delaware, Lackawanna & Western 

 Railroad from Ithaca to Brookton. This region consists of farm lands 

 and occasional small patches of timber. The hillsides are often thickly 

 covered with underbrush and sumac. There is considerable clover and 

 timothy, and good stands of blackberry are found. This is a good collect- 

 ing ground for most species of the genus Ceresa. 



Station Q, the valley of Six Mile Creek. This is probably the best 

 collecting ground in the basin. The floor of the valley is rich in sweet 

 clover, elder, blackberry, aster, daisy, and joe-pye weed, all of which 

 support Membracidae. In the lower parts of the valley are many locusts, 

 elms, and young sycamores, on which certain species may be found the 

 year round. The slopes are thickly wooded with a large variety of young 

 trees, containing some stands of beech and dogwood, and considerable 

 oak, butternut, and chestnut. Telamona prvinosa has been taken only at 

 this station. Vanduzea arquafa and Thelia bimaculata are extremeh' abun- 

 dant. The entire life history of Ceresa huhalus has been worked out on the 

 young elms and the sweet clover below the dam. 



Station R, the region east of Ithaca between Six Mile Creek and the 

 boundary of Station A. The section includes farm lands, a few timbered 

 tracts, and the interesting Cascadilla Gorge. The last-named area 

 is the richest part of the station and contains considerable Virginia 

 creeper, elder, and small trees. The farms generally include fields of alfalfa 

 and buckwheat. Telamona anipelopsidis, Ceresa diceros, and Carnpyl- 

 enchia latipes are abundant in this region, and Glosso7iotus crataegi has 

 occasionally been found. 



Station S, Fall Creek valley from Forest Home eastward. This is a 

 winding, sparsely wooded valley, rich in bushes and shrubs. The trees 

 are generally small and scattered. The slopes of the valley are not pre- 

 cipitous and are often cultivated. Small crops, clover, alfalfa, potatoes, 

 and timothy provide fair collecting opportunities. 



Station T, the region northeast of Ithaca, from the golf links over a ram- 

 bling territory. There are scattered patches of timber, well-wooded road- 

 sides, some fiTiit trees, and a great deal of goldenrod, thistle, joe-pye weed, 

 aster, and sweet clover. The sweeping is excellent in this region.
