Cyrtosia fenestrata, Fitch. 

 The Fitch type of this species is certainly identical with the form 

 determined by me with some doubt as mtiticus, Fabr., in my Studies in 

 North American Membracidae, and the same determination is found in the 

 Fitch material in the National Museum. Whether this is the true midicus 

 of Fabricius is open to some doubt, although it was so determined by Dr. 

 Uhler for the Cornell University collection, and it agrees very closely with 

 Stal's description of the Fabrician type. For the present I would use the 

 name Cyrtoiobus fenestratus for this species, placing mtiticus, Fabr., as a 

 species still unrecognized in our present collections. 



Cyrtoiobus vau, Say. 



My determination of this species is correct by both the Harris and 



Fitch material. 



Tettigoniella gothica, Sign. 



In the Harris collection is an example of this insect labelled 



Tettigonia hieroglyphica, Say, but as this specimen was not determined by 



Say, it need not affect the synonymy of the species. Dr. Harris may not 



have known the western form to which Dr. Ball has recently restricted the 



name hieroglyphica, Say. 



Pediopsis trimaculata. Fitch. 

 An examination of the type in the Fitch collection shows that 

 Osborn and Ball were right in placing my insignis as a synonym of this 

 species. It is poorly described by Dr. Fitch. 



Idiocerus maculipennis, Fitch. 



I was unable to find the type of this species in the Fitch collection. 



It is, however, easily recognized by the description given by Dr. Fitch. 



Unfortunately, this name was preoccupied by maculipennis, Curtis. I 



therefore propose the name Idiocerus Fitchi for our American species. 



Deltocephalm Melscheimeri, Fitch. 

 A careful examination of the Fitch type verifies Prof. Osborn's 

 determination as made in his Jassidse of New York State (20th Rept., N. 

 Y. State Ent., p. 521, 1905). The name affinis, G. & B., will designate 

 the larger species formerly determined by me as Melscheimeri. 



Scaphoideus auronitens, Prov. 

 In the Harris collection I find this species labelled Jassus areatus, 

 Harris. I quote this MS. name, as it has already appeared in print, and 

 in my Catalogue I suggested it as a possible misprint for Platymetopius 

 acutus, which it now seems was erroneous.
