question, which is of importance as affecting the name of a common 

 pest. Could the Association of Economic Entomologists take it up?

 longer than usual. Boulder, with Lasius, May, 1907.

 notes were made on the male of R. confusella, variety, collected on

 W. Ckll.). 



Male. Pale pink, eyes dark red; mesothorax darker than head and 

 prothorax, no dark bands; legs rather dark; four long white caudal 

 filaments, the outer much shorter than the inner; head seen from above 

 obtusely triangular, widest behind the eyes; length of wing, 1326 /*. 



The accompanying female was pale pink, elongate, with no evident 

 lateral tassels; caudal bristles about 120 A*. It appeared to be in the 

 penultimate stage. 



OOCCIN^ 



I follow the Fernald Catalogue as to Coccus, but it is possible that a 

 different interpretation may hold. At all events, the name Coccus 

 should properly have been restricted to what we now call Kermes, 

 following the plan of selecting the best-known native, economic species. 

 Moreover Coccus is the ancient name of Kermes.
