279. Gossyparia spuria (Moden). This species was found attacking a few 

 Elm trees in the city of Toronto in 1906, and since that time it has spread to nearly 

 all parts of Toronto and has proven to be a very destructive pest. 



293. Eriococcus horealis (Ckll.). This is a native species found on Willow 

 (Salix) at Dawson City, 64 degrees North Lat., by Mr. John Morley, in 1899. A-^ 

 far as I am aware this species has not been found in any other locality. 



391. Phenacoccus aceris (Sign.). It has been received from Amherstburg and 

 St. Catharines, Ontario. So far it has confined its attacks to the Soft Maple (Acer 

 saccharinum) . Several trees were badly attacked by this scale and the writer 

 ordered the destruction of the infested trees. 



401. Phenacoccus dearnessi (King). This species was found by John Dear- 

 nc?5 on Hawthorne (Crataegus sp.) at London, Ontario. 



454. Pseudococcus citri (Risso). It is found in conservatories on many 

 species of plant throughout Canada. Closely related species or varieties are found 

 on the Apple and other Eosaceous plants in the open, at Guelph and Toronto, 

 Ontario. 



490. Pseudococcus longispinus (Targ.). Very abundant on many species of 

 indoor plants in all parts of the Dominion. 



529. Pseudococcus trifoUi (Forbes). The writer found this species very 

 abundant on the roots of cultivated clover at Collingwood, Ontario. 



572. Ripersia lasii (Ckll.). This species was found in Ants' nest (Lasiu^ 

 aiitericanus) at Toronto, Canada, in 1897, by Mr. E. J. Crew. The writer has 

 found this species in Ants' nest at Guelph, Ontario.

661. Pulvinaria floccifera (Westw.). This species was found in a green- 

 house at Ottawa, Canada, December 15, 1894, on leaves of Brassia verrucosa. King 

 described this as a separate species, P. hrassiae. 



675. Pulvinaria occidentalis (Ckll.). This species was 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 has also been found by Dr. Mackay, June 

 14. 1901, on Gooseberry bushes at Dartmouth, Nova Scotia. 



699. Pulvinaria vitis (Linn.). — P. innumerahilis (Rathvon) — P. tilia'. 

 (King and Ckll.) — P. vihurni (King). This species is commonly known as the 

 Cottony Maple Scale and is found all over the Western part of the Province at 

 least, and also in the woods at Aylmer in the Province of Quebec, nine miles from 

 Ottawa. As the name indicates it attacks the Maple chiefly, and in cities often 

 <loes much damage to maple shade trees. It is, however, rarely abundant for many 

 seasons in succession, because of the attacks of parasites. Although the maple trees 

 are the ones most commonly attacked, the scale is found on many other trees and 

 shrubs as well. It has been found at Guelph on Acer saccharum, A. saccharimim.

 Crataegus sp., Populus alba, Salix sp., Cornus stolonifera, Ilex verticillata, Spiraea 

 sdlirifolia, and Vitis cordifolia. 



724. Eriopeltis festucce (Fonse). The Cottony Grass Scale was found by 

 Mr. A. H. Mackay, on grass in large numbers in Cumberland Co., Nova Scotia, in 

 1889. It has occurred in conspicuous numbers several times in Nova Scotia and
