Hab. — On rosebush at Sherbrooke, Quebec; found by Mrs. Brooks 



(Dr. Fletcher in litt). E. rosce. differs very materially from the European 



Lecanium (Eulecanium rosarum ) by the scale being nearly circular in 



outline, and having a 6- and 7-jointed antenna, while E. rosarum has a 



7- and 8-jointed antenna.
