Station U, the territory on the east side of the lake north of Aurora. 

 This station has been the least worked of all of the regions represented, 

 only two or three collecting trips having been made in this part of the 

 basin. The country is sparsely wooded and well cultivated. There is 

 considerable fruit and much grain. Few records have been obtained from 

 this station. 



Statio7i V, the Montezuma Marshes and neighboring territory. A 

 considerable number of records from this station have accumulated as 

 a result of collecting done by members of parties visiting the marshes on 

 botanical excursions. The region is rich in swamp flora and the Mem- 

 bracidae taken have been largely grass- and shrub-inhabiting forms. This 

 is one of the few regions where Publilia concava has been found. 



COLLECTIONS 



The collections used as a basis for determinations and comparisons in 

 the course of this study have been largely the Cornell University col- 

 lection, the New York State Museum collection at Albany, the collection 

 in the United States National Museum at Washington, D. C, the col- 

 lection in the Philadelphia Academy of Science, the private collection of 

 E. P. Van Duzee, of the University of California, and the private collection 

 of the author. 



The Coi'nell University collection of Membracidae is very complete in 

 local forms of the family, having been built up by the addition of depart- 

 mental material, students' collections, and purchased material, thru a 

 period of many years. It includes paratypes of the species described by 

 Van Duzee (1908 a) and a large proportion of the material has been deter- 

 mined by this authority. Representatives of nearly all of the species here 

 mentioned are to be found in this collection. 



The New York State Museum collection, at Albany, New York, is 

 extremely valuable owing to the fact that it contains the types of Fitch's 

 species, described by him many years ago (Fitch, 1851). Thru the courtesy 

 of Dr. E. P. Felt it has been possible to compare the material from the basin 

 with this type material, and the author is greatly indebted to Dr. Felt 

 and to Mr. Young for their continued kindness and interest in this respect. 

 Fitch's types are kept separate from the remainder of the collection, and 

 have proved extremely valuable for comparison since they include a 

 number of the forms here discussed (Funkhouscr, 1915 d).
