This is anolhrr importc-d species which has apparently become well 

 established in this counlrv. il having b.-en b.und in considerable numbers 

 in the- vicinitv of Rochester N. V. during the last four years. It was 

 brought to the writer's attenl,on by Mr 11. C. Peck, a nursery inspector, 

 sendin.T infested willows with an in.,uiry as to the cause- of the trouble. 

 Repeated efforts to ascertain th.- identiU' of the species met with failure, 

 till carlv spring of 1902, when living mate-rial was sent to Prof. j. j. 

 Kieffer a well recognized authoritv in this grou,., who k,n<lly dc-lermmed 



the insect. 



Injuries. This pest produces many celled galls in the- stems of small 

 .•illows which are grown by nurserymen for the purp.>se of tying stock ,nlo 

 bundles These abnormal growths make the willows brittle and conse- 

 nuentlv unhl them for binding purposes. This species may eventually 

 prove 'a verv s<-rious pest to growers of willow for basket purposes, as 

 infestc-d shoots could not be used in this industry any more than for tying 



trees.
