SOME RECENT CONTRIBUTIONS TO HEMIP TEROLOGY. 



BY J. R. DE LA TORRE BUENO, WHITE PLAINS, N. Y. 



For the noteworthy papers on Hemiptera to which these notes apply, 

 I am indebted to the courtesy of the authors. They comprise "Remarques 

 sur quelques Hemipteres de 1'Amerique du Nord," 1 another of Dr. G. 

 Horvath's valuable contributions to a proper knowledge of our fauna ; 

 " Tableau Synoptique des Ambrysuset Descriptions d'Espcces nouvelles," 2 

 by Prof. A. L. Montandon ; "The Genus Cori/us, with a Review of the 

 North and Middle American species," by Prof. J. C. Hambleton ; 

 " Biological Notes on Oriental Hemiptera," 3 by J. C. Kershaw and G. \V. 

 Kirkaldy ; and last, but emphatically not least, " Some Remarks on the 

 Phytogeny of the Hemiptera Heteroptera," 48 by G. W. Kirkaldy. 



Dr. Horvath in his article confirms many doubts I have had as to 

 the identity of American with European species of Hemiptera. His studies 

 have resulted in the description as new of a number of species hitherto 

 known to us in America by the names of their European congeners, and 

 in the classification of a number of synonymies in other forms. His 

 deductions are, of course, supported by tenable arguments, and 

 strengthened by his great experience and familiarity with the Patoarctic 

 fauna. His results are summarized below : 

 Corizus crassicornis, Linne. 

 = nova£boracensis, Sign. 

 Corizus viridicatus, Uhler, is a good species, and not a synonym 

 of C hyalinus, Fabricius. 



• Corizus suite., Fabricius. 



= Rhopalus pictipes, Stiil. 



Nysius thy mi, Wolff. 



= Saint Cyri, Provancher. 



—groenlandicus, Provancher. 

 Nysius erica, Schilling. 



= angustatus, Uliler.
