No other records of the species were found. P. eximius Lee., 

 like P. comptus, is a central North American species. It has 

 been found at Topeka, Kansas (Popenoe), Texas and Illinois 

 (Bolter). LeConte's P. se tiger us was described from Kansas 

 specimens, but I have found no other record of this species. 

 Phytonomus quadricollis Lee. has rather a higher range of al- 

 titude than the other species, according to the records of its 

 occurrence. LeConte described the species from Dakota, and 

 the Bolter collection contains specimens from Yukon, Las 

 Vegas, New Mexico and Wyoming. Phytonomus pubicollis 

 Lee and P. seriatus Mann, are northwestern species. LeConte 

 gives Vancouver Island as the source of his type specimen. 

 The Lugger collection contains a single specimen, labeled from 

 Alaska, which I have determined as this species. Hamilton 

 notes P. seriatus as occurring at Kadjak, Alaska.
