PULVINARIA vms, var. RIBESI^E (pages 66, 67). 



THE chalcidid parasite, whose method of oviposition 

 has been described at page 66 of this volume, has been 

 identified by Dr. L. 0. Howard, Entomologist, U.S. De- 

 partment of Agriculture, as probably Blastotlirix sericea, 

 Dalman. He also informs me that this insect "was 

 reared by Kollar from coccids on Tilia and Prunus, 

 as well as on JEsculus, Acer, and Corylus. Bienhard 

 and Tscheck also reared it from bark-lice on plums 

 and on Garpinus. Probably all of these scale-insects 

 belong to the Lecanium group. In this country we 

 find Blastotlirix nearly always coming from Lecanium, 

 and this is the same with the comparatively few exotic 

 species. Blastotlirix longipennis, for example, has 

 become rather widely distributed commercially, and is 

 parasitic upon various species of Lecanium. 91 



GENUS LECANIUM (page 75). 



The members of this genus have now been referred 

 to Coccus, type C. (Lecanium) hesperidum, Linn. In a 

 paper " On the Type of the Genus Coccus, L.," Mrs. 

 C. H. Fernald,* Amherst, Mass., U.S.A., says : " The 



* 'Canadian Entomologist/ 1902 (?), p. 232. The separate pages were 

 sent to me without any reference to volume or year, but as they reached me 

 on September 24th, 1902, I assume that Mrs. Fernald's paper will be found 

 in the volume for that year.
