THE COCCID.E OF BRITISH NORTH AMERICA. 



BY GEO. B. KING, LAWRENCE, MASS. 

 ( Continued from page 200.) 



Since writing my first paper on the Coccidce of British North America, 

 a very large amount of new and interesting scale insects have been sent to 

 me for study by Dr. Fletcher and Mr. John Dearness. In nearly every 

 instance the twigs sent showed beyond question that the insects occurred 

 upon the food-plants infested in injurious numbers ; especially so of those 

 found on blackberry, hazel-nut, spiraea, viburnum and oak. The following 

 are new to the Canadian list : 



Pulvinaria Mice, King; and Ckll., 1S9S. (Native.) Mr. John 

 Dearness sent these from Thedford, Out , on Ccphalanthus occidentalis. 

 It was first recorded from Mass., found on Tilia Americana, Quercus and 

 Ulmus, and described as a sub-sp. of P. innumerabilis, but further study 

 proves it to be quite different from that species, and it should stand as 

 P. tilue. 



Eulecanium caprece, L., 17 58. (Introduced.) Found on a peach 

 tree growing in a conservatory at Dartmouth, Nova Scotia, June 20, 1901, 

 by Dr. A. H. Mackay, of Halifax, N. S. Dr. L. Reh, of Hamburg, 

 Germany, has sent me this species infesting the following food-plants : 

 Pyrus mains, P. communis, Alnus sp., Cratcegus coccinea, Primus 

 domestica, Tilia so., and Aesculus hippocastaneum. The species was 

 originally described as Coccus caprece, and has been recorded as Coccus 

 cyprceola, Dalm.; Coccus gibber, Dalm., and Lccanium salicis, Bouche. 

 Linne described his from Salix sp.; it has since been found on Salix 

 alba and rose in England. 



Eulecanium* corylifex, Fitch, 1S56. (Native.) Sent by Dr. Fletcher, 

 infesting in a serious manner Corylus rostrata and Viburnum pubescens, 

 growing intermingled at Aylmer, Pro v. Quebec, 1901. Originally 

 described from N. Y. 



Eulecanium quercifex, Fitch, 1856. (Native.) Found on oak at 

 Knowlton, Prov. Quebec, by Miss A. Wood. The species is a common 

 one in the U. S., and was described from N. Y. 



Eulecanium villi, Bouche', 185 1. (Perhaps introduced.) Last spring 

 I received a scale from Dr. Reh, of Hamburg, Germany, infesting 

 Vitis vinifera, Pyrus communis, P. mains, Prunus armenica, P. 



*The species of Eulecanium have hitherto been placed in Lecanium : it is here 

 proposed to regard the genus as a valid one.
