CONTRIBUTIONS TO THE KNOWLEDGE OF MASSACHUSETTS COCCIDAE.—I

Extract

The published records of the occurrence of coccids in Massachusetts are so scattered and the number found to exist is so large, that it seems quite desirable that they should be brought together and published in one entomological journal. So far as I can learn from careful search of the literature up to January, 1896, there had been only 13 species recorded. Since then the list has increased to 74. A list of the 13 species is: Aspidiotus perniciousus, Mytilaspsis pomorum, Chionapis furfurus, C. spartinae, Aulacaspis bromeliae, Dactylopius adonidum, Phenacoccus aceris, Gossyparia ulmi, Orthezia insignis, Pulvinaria innumerabilis, Lecanium hesperidum, L. platycerii, and L. filicum. A check-list reference-list of the literature of Massachusetts Coccidae will be published in a supplementary article.
