230 ENTOMOLOGICAL NEWS. [Sept., '05 



tribution to the terminolog}^ or nomenclature of that science 

 as a whole has appeared. That portion of entomology is at 

 present much neglected. 



Going outside of the field of entomology, we find the most 

 important writings on this subject, strange though it may seem. 

 These the writer is not prepared to list at present, as they in- 

 clude writings in all branches of natural science. A few have 

 been briefly mentioned. Though not touching entomological 

 nomenclature in particular, yet they embrace it, furnishing 

 the very fundamental principles of nomenclatorial science to 

 which we must look. For this reason, and on account of 

 their recent publication and reliableness, the two large dic- 

 tionaries mentioned in the general text are now the authorities 

 on entomological terms. 



Galeruca pomonae Scopoli, in North America. 

 FREDERICK KNAB, WASHINGTON, D. C. 



In the collection of the Illinois State Laboratory of Natural 

 History are specimens of a Galeruca taken at Urbana, Illinois, 

 which the writer at once recognized as distinct from our native 

 species, Galeruca externa. It was thought likely that these 

 beetles were the same species as the Galeruca tanaceti recorded 

 by Mr. Charles Dury from Cincinnati, Ohio, in ENTOMO- 

 LOGICAL NEWS, v. 14, p. 146. However, comparison with 

 descriptions and European material showed that the present 

 species, without a doubt, is the Galeruca pomonce of Scopoli. 

 The specimens agree very well with the careful description of 

 the species by Weise in Insccten Dcutschlands, v. 6, p. 652-655, 

 as well as with European specimens in the writer's collection. 

 A subsequent examination of Mr. Dury's material showed 

 that the specimens taken by him at Cincinnati are not Galeruca 

 tanaceti but likewise G. pomoncc. So as far as we know at 

 present Galeruca tanaceti does not occur in North America. 

 Mr. Dury informed me that G. pomontc has also been taken by 

 Prof. W. S. Blatchley in Indiana. 



The specimens of Galeruca ponwn<z before me are short and 

 very convex with three prominent highly polished costae upon
