DESCRIPTIONS OF A NEW GENUS AND SPECIES OF 

 BUPRESTIDAE FROM ARIZONA (COL.). 



BY W. S. FISHER, Bureau of Entomology. 



TRIBE ACMAEODERINI. 

 (Julodini Lee. and Horn, not Lacordaire.) 



The classification used below is to a large measure based upon 

 that proposed by Kerremans although alterations have been 

 made to suit our fauna, and the tribe name has been changed 

 in accordance with our established rules of nomenclature. For 

 this tribe Kerremans used the name Polycesiini, based on the 

 genus Polyccsta described by Solier in 1833, but as Aanaeodera 

 was described by Eschscholtz in 1829, the tribe must take its name 

 from the latter genus, and in fact, Kerremans used this name in 

 his earlier works. 



Key to the Nortli American genera. 



1 . Tarsal claws simple Polycestti Sol. 



Tarsal claws toothed 2 



2 . Scutellum visible 3 



Scutellum not visible Acmaeodera Esch. 



3 . Metasternal episterna covered by elytra 4 



Metasternal episterna not covered by elytra Chrysophnnu Lee. 



4 . Tarsal claws deeply toothed Ptosima Sol. 



Tarsal claws with inconspicuous tooth at base ."> 



5. Tarsi cordiform (South American.) Tyiidaris Thorns. 



Tarsi slender, not cordiform Paralyiidaris Fisher. 



Thomson in describing the genus Tyndaris says that the tarsal 

 claws are simple, but this was probably due to the fact, that he 

 was comparing it with the genus Ptosima, which has the claws 

 deeply toothed, but Kerremans corrects this statement in his 

 Monograph, and says that the claws are lobed at the base. 

 L,e Conte and Horn, and Kerremans places Chrysophana among 

 the genera with simple claws, but Kerremans probably has not 

 seen any specimens of ( 'hyrsophana, as the tarsal claws are almost
