New Brunswick. This species has been recorded at Ottawa, Ontario, but Dr. 

 Fletcher says, it was a mistake and, if so, we have no record of this species in 

 Ontario. 



848. Coccus hesperidum (Linn.). Commonly known as the Soft Scale, is 

 found abundantly in conservatories in Oleander, Orange, Lemon, etc., in all the 

 provinces of the Dominion. 



860. Coccus pseudohesperidum (Ckll.). This is a very large species found 

 on Orchids in the conservatories at Guelph and Ottawa. It is usually most abun- 

 dant on Cattleya sp. These are the only records for this species. Its nativity is 

 unknown. 



902. Toumeyella pini (King). This species was found by Mr. J. Dearness 

 on Austrian Pine (Pinus austriaca), at London, Ontario. 



902b. Toumeyella liriodendri (Gmel.). This species was first reported by Dr. 

 Fletcher on Tulip at Ottawa, Ontario. 



911. Eulecanium persicce (Craw). — Fab. 1. — E. armeniacum) . In Mr. 

 King's account of the scales of British North America he reports this species infest- 

 ing orchards at Sherbrooke, Quebec, in 1899. This species has also been reported 

 from Prince Edward Island. M 



918, Eulecanium caryce (Fitch). This species is said to be the largest known 

 species of Eulecanium. It has been in Ontario for at least 12 years, having been 

 first found by Dr. Fletcher in the Niagara district in 1898. Judging from the 

 fact that it has been found in that district on Peach trees and that we have found it 

 plentiful on forest trees at Guelph, it probably occurs at least all over the south- 

 western part of Ontario. The scale is seldom -sufficiently injurious enough to cause 

 any alarm. It has been found on Crataegus sp.; Ulmus americana; TJlmus race- 

 mosa; Ostrya virginica; Carpinus caroliniana at Guelph, Ontario, and on the 

 Peach (Prunus persica) at St. Catharines, Ontario. It has also been reported from 

 Nova Scotia on forest trees. It is usually accompanied with parasites in Ontario. 



921. Eulecanium cerasifex (Fitch). — E. canadense (Ckll.); E. caryarum 

 (Ckll.) ; N. corylifex (Fitch) ; E. cynoshati (Fitch) ; E. fraxini, (King) ; E. 

 guignardi (King) ; E. juglandis (Bouche) ; E. maclurarum (Ckll.) ; E. wehsteri 

 (Ckll. and King); E. fitcliii (Lign) ; C. pruinosum (Cqul.). The New York 

 Plum Scale has become the most common scale in Ontario and Quebec. The writer 

 has found this scale on a great range of trees, shrubs, vines and herbs, the following 

 being a list of those so far recorded: Acer nigra, Acer saccharum, Acer saccliari- 

 num, Acer spicatum, Acer negundo, and many varieties of the above mentioned 

 species, Aesculus liippocastanum, Stapliylea trifolia, Rliamnis cathartica, Psedera 

 quinquefolia, Vitis cordifolia, Tilia americana, Tilia europea, Carya ovata, Carya 

 glabra, Corylus americana, Ostrya virginiana, Carpinus caroliniana, Betula tenia, 

 Betula lutea, Alnus incana, Fagus grandifolia, Castanea dentata, Quercu^ rohur, 

 Quercus macrocarpa, Quercus rubra, Quercus coccinea, Ulmus americana, TJlmus 

 campestris, Ulmus fulva, Ulmu^ racemosa, Celtis occidentalis, Juglans nigra, Jug- - 

 lans cinerea, Salix sp., Populus alba, Populus tremuloides, P. balsamifera, Populus 

 deltoides, Crataegus sp., Riibus occidentalis, Rubus strigosus, Prunus serotina, 

 Prunus virginiana, Prunus nigra, Prunus persica, Pyrus malus, Pyrus japonica, I 

 Pyinis communis J Amelanchier canadensis, Sambucus canadensis, Sambucus race- 

 mosa, Ribes nigrum, Ribes vulgare, Hamamelis virginiana, Ribes cynoshati, Cornus 

 stolonifera, zanthoxylum americanum. In addition to these many species of herbs 

 near infested trees. It is spread over practically the whole of Ontario and the 

 eastern provinces. Though not so destructive as the Oyster Shell Scale, it is often 

 quite injurious where abundant and sometimes kills the infested tree.
