Pulvinaria, Targ. 



Pulvinaria innumerabilis, Rathv., 1854. (Native.) The cottony 

 maple scale. A common North American species. Recorded from 

 grapevines and maple at London and other places in Western Ontario.

1898, p. 91. 



Pulvinaria brassice, Ckll., 1895. (Nativity unknown.) Now con- 

 sidered identical with P. floccifera, Westw. Was found in a greenhouse 

 at Ottawa, Canada, Dec. 15, 1894, on leaves of Brassia verrucosa. The 

 plant is a native of Mexico, and was purchased from a New Jersey florist.

Pulvinaria occidentalism Ckll., 1897. (Nativity uncertain.) Found 

 infesting in a serious manner a whole plantation of red and white currant 

 at Chilliwack, British Columbia, by Rev. G. W. Taylor, in the spring of 



1899. In July (the same year) Dr. Fletcher visited the plantation and 

 found these scales to be in enormous numbers, the white flocculent threads 

 giving the bushes the same appearance as if a light fall of snow were upon 

 them. It may turn out, however, that when we can get some of the 

 European species of P. ribesicz to compare with it, it may prove to be 

 that species.

Eriopeltis, Sign. 



Eriopeltis /estuccp.,Fonse, 1834. (Introduced.) The cottony grass 

 scale. This was found by Mr. A. H. McKay, on grass, in large numbers 

 in Cumberland Co., Nova Scotia, in 1889. It was cited as a new species 

 of Rhizococcus, and is said to occur in Dakota, Indiana and Illinois, on 

 timothy and red-top grass. It is parasited by a Dipteron, Leucopis 

 bellula. It has occurred, in conspicuous numbers, several times in Nova 

 Scotia and New Brunswick of late years.

Diaspin^. 

 Aspidiotus, Bouche.

 ivy, etc. I have also received it on palm found in a house at London, 

 Ontario, by Mr. John Dearness.
