In the bulletin of 1907 it was stated that Brood XX was of doubtful 

 occurrence in Wise County. In a recent letter Dr. Alarlatt reports 

 that after an examination of the old records he concludes that this 

 brood really does not exist in Virginia, but, on the other hand, the 

 occurrence of Brood XIX in the costal plain of the state seems to be 

 well substantiated.

A REVIEW OF THE GENUS PCECILONOTA AS 

 FOUND IN AMERICA NORTH OF MEXICO (COLE- 

 OPTERA, FAMILY BUPRESTID^) WITH DE- 

 SCRIPTIONS OF NEW SPECIES. 



By W. J. Chamberlin, 



Forest Entomologist, Oregon Agricultural College. 



The genus Poccilonoia was erected by Eschscholtz^ in 1829. 

 The species are closely related to those of the genus Dicerca, but 

 may be separated at once by the broad scutellum.
