SwAiNE (J. M.). Platypus wiUoni, a New Species of Platypus from 

 British Columbia (Platypodidae, Coleoptera). — Canadian Entomo- 

 logist, London, Ont., xlviii, no. 3, March 1916, pp. 97-100, 

 2 plates. 



Platypus wilsoni, which is here described, attacks all species of 

 conifers on the British Columbia coast, with the exception of Thuya 

 and Chamaecyparis, but is most abundant in Pseudotsuga, Tsuga and 

 Abies grandis. Dying or weakened trees and freshly cut logs are 

 usually attacked, but living trees may be affected. The adults bore 

 into the bark and wood of the host, the walls of the tunnels becoming 

 coated with a fungus which serves as food for the larva, and in a less 

 degree for the adult.

— Canadian Entomologist, London, Ont., xviii, no. 3, March 1916, 

 pp. 105-106. 



The Chrysomelid, Plagiodera versicolor, Laich., has done considerable 

 damage during the past few summers to poplars and willows in several 

 districts in New Jersey. It is probable thajb both the larval and adult 

 stages can be kept in check by the use of arsenical sprays.
