be placed as a synonym of Graphlsurm Lee. It becomes necessary 

 to give a new name to the genus which was fully defined by Dr. 

 Horn under the name Graphisurus (Trans. Amer. Ent. Soc. vol. 

 viii, p. 129), and of which the type is biguttatus (Liopus) Lee. This 

 genus I propose to call Ceratographis, and in order to show the change 

 of nomenclature more clearly I tabulate the genera -and species with 

 their new synonyms as follows : 



GRAPHISURUS Lee. Lacoid. 

 TJrographis Horn. 

 G. triang-ulifer Hald. 

 G. fasciatus De Geer. 

 CERATOGRAPHIS n. g. 

 Graphisurus Horn. 

 C. biguttata (Liopus) Lee. 



ACANTHOCINUS Stepli. 

 Grnphisur us Ki r by . 

 A. obsoletus Oliv. 



pnsUl.us {Graphisurus) Kirby. 

 A. obliquus Lee. 

 A. spectabilis Lee. 

 A. nodosus Fabr. 



Along with Dr. Horn, who has very kindly given me valuable 

 assistance in naming North American Longicorns, I have been look- 

 ing into the species of the genus 3Iecas in our Museum collection. 

 We find that the Saperda cana of Newman is synonymous, not with 

 Mecas per grata Say, as Dr. Horn's list has it, but with Mecas satur- 

 nina Lee. Newman's name is the older. 



As synonymous with Mecas inornata Say we place Mecas (Saperda) 

 cinerea Newm., and Mecas senescens Bates. The synonymy of these 

 two species, which were shown by Blanchard (Ent. Amer. vol. iii, 

 p. 86) to be distinct, is then as follows : 



Mecas inornata Say. 

 cinerea Newm. 

 senescens Bates. 



Mecas cana Newm. 

 saturnina Lee. 



Additional Notes. 



BY GEORGE H. HORN, M. D. 



At the time of my first visit to London the type of Graphisurus 

 puslllus could be but imperfectly studied. The type proves to be a 

 very small AcantJwcinus obsoletus, and Kirby's description applies 

 with great accuracy to Liopus biguttatus. Not desiring to perpetuate 

 an error, Mr. Gahan, at my request, after his own study, has pre- 

 pared the note which precedes.
