We have now 59 species of Coccidcs recorded from British North 

 America ; the two more, probably new, would make 61 species. 



Distribution by provinces : Ontario has produced the largest portion, 

 48 species; Prince Edward Island and Nova Scotia with 13 each; Quebec 

 next with 9 ; British Columbia with 6, and Manitoba, 5. 



Ottawa seems to lead, with London next, and then Niagara and St. 

 Catharines. Very few other places produce more than two or three 

 species each, and many only one. 



At present there are 37 native and 22 introduced species. 



I shall be pleased to receive and determine any material in Coccidte 

 found in Canada. I would say in this connection that the last of May 

 and June are the two best months to find the genus Pu/vinaria, and 

 collecting for other species can be done the year round.
