THE CANAblAN ENTOMOLOGIST. 109 



CONTRIBUTIONS TO THE KNOWLEDGE OF MASSACHUS- 

 ETTS COCCIDAL.—I. 



BY GEO. B. KING, LAWRENCE, MASS. 



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, 1S96, there had been only 13 species 

 recorded. Since then the list has increased to 74. A list of the 1 3 species 

 is: Aspidiotus pertiiciosus, Mytilaspsis pomoruni, Chiofiapsis fttr/tirus, 

 C. spariitice, Aulacaspis bromelice, Dadylopius adonidutn, Pheiiacoccus 

 aceri's, Gossyparia ul?ni, Orthezia insignis, Fiilvinaria inmimerabilis, 

 LecaniufH hesperidu?n, L. p/atycerii, and L. filiaim. A check-list 

 reference-list of the literature of Massachusetts Coccidsfi will be pub- 

 lished in a supplementary article. Distribution, food plants, parasites, 

 and predaceous enemies (known to me to occur in Massachusetts on 

 coccids) will be given ; also, the distribution of the Massachusetts coccids 

 found in other States. This will show to some extent what little is 

 generally known of these most destructive insects in this country. The 

 only States that know, or have any material knowledge of, the number of 

 these pests that occur within their borders are Colorado, California, 

 Florida, New York, New Mexico, and Massachusetts ; Washington, D. 



C, should also be added; New Mexico and Massachusetts leading, the 



former having 73 and the latter 74 species. I. means introduced species ; 



N., native species. The year placed after the author's name is the year 



in which the insect was described, and the other is the year when it was 



first known to occur in the State. The foreign distribution will only be 



given when found necessary.

This species was discovered by Dr. Hagen in a greenhouse at 

 Cambridge, Mass., and this is the only instance that I know of its being 

 found in this State. It is quite common in California.
