 Iowa, Nebraska, South Dakota and Southern California. Dr. 

 Fletcher has recorded the species also from Leamington, Ont., 

 Canada. 



While nurserymen and orchardists as well as entomologists regard 

 Chionaspis furfura of less importance than Mytilaspis pomorum, it 

 is admitted to be very destructive at times. Prof. Osborn writing of 

 the insect says : " This species is at times very plentiful and 

 destructive in our orchards and whenever seen should be promptly 

 treated." Dr. Lintner says, "This scale insect, known to science as 

 Chionaspis furfurus (Fitch), is quite common in the state of New 

 York, where, it is believed to be more numerous and more injurious 

 than in any other of the United States. I have recently seen an 

 orchard of the KiefTer pear, in Columbia Co., N. Y., in which the 

 trunks of from three to four inches in diameter, were so thickly 

 coated with the scale that at a little distance they appeared as if 

 they had been whitewashed." I have frequently seen apple and 

 pear trees in nurseries in Massachusetts so badly infested as to have 

 the appearance described by Dr. Lintner. This species is also 

 occasionally injurious to currant and Japanese quince, and Dr. L. O. 

 Howard reports it as being so abundant on Mountain ash in the 

 Catskill mountains that hardly a twig or branch was found unin- 

 fested. Prof. Webster has quoted Mr. R. B. Fulton, Oxford, Miss., 

 as follows : "This insect has been ruinous to the black-cap rasp- 

 berry in this vicinity for the last three or four years. Old raspberry 

 plants have been dug up and thrown away to get rid of the pest. . . . 

 It multiplies so fast that it seems useless to try to kill it by any 

 application to the plant." 



Various authors have already published this species as infesting 

 apple, pear, cherry, currant, Japan quince, crab-apple, black cherry, 

 choke cherry, mountain ash, European mountain ash, peach and. 

 black walnut. Mr. King of Lawrence, Mass., has 'sent me speci- 

 mens on Rhamnus catharticus and Clethra alnifolia. Mr. Kirkland 

 has informed me of its occurrence on Pyrns arbutifolia, P. nigra, P. 

 hetetophylla, P. salicifolia pendula, P.floribunda, P. spectabilis and P. 

 pinnatifolia. Prof. Osborn recorded it on black-cap raspberry and 

 Morgan on Ribes sangiiineum.
