C. furfurus Fitch. The "scurfy 

 scale" or "Harris louse." On 

 orchard trees, chiefly apple 

 and pear, throughout the 

 State, and sometimes de- 

 structive. Also occurs on 

 poplar and other shade 

 trees; rarely in troublesome 

 numbers. 



C. lintneri Comst. Locally com- 

 mon on alder in neighbor- 

 ing States and probably in 

 New Jersey. 



C. ortholobis Comst. Mass, to 

 Ohio and probably New Jer- 

 sey, on poplar and willow. 



C. pinifoliae Fitch. Not uncom- 

 mon on pine trees through- 

 out the State, and sometimes locally abundant. 



C. salicis-nigrae Walsh. A common willow scale found at New Bruns- 

 wick and elsewhere in the State. Occurs also on poplar, tulip tree, 

 dog-wood, etc. 



C. spartinae Comst. Found on the salt marsh grass, "Spartina stricta." 



DIASPIS Costa.

ornamental plants. 



D. bromeliae Kern. Massachusets to District of Columbia on various 

 green-house plants. 



D. carueli Targ. A Juniper scale. Found occasionally in nurseries, and 

 no doubt distributed by them throughout the State, principally on the 

 trailing variety. 



D. juniper! Bouche. Another Juniper scale, but also found on arbor vitae 

 in nurseries. 



D. echinocacti Bouche, var. cacti Comst. A common green-house scale. 



AULACASPIS Ckll. 



A. pentagona Targ. The "West India peach scale." Has occurred 

 sparingly on young peach trees in South Jersey, but seems not to do 

 well. The scale is a very destructive one where it thrives. 



A. rosae Bouche. The "Rose Scale." Throughout the State. Thrives 

 best on plants growing in the shade. Also attacks blackberry and 

 raspberry; sometimes in destructive numbers. 



PINNASPIS Ckll. 



P. buxi Bouche. On boxwood. I have seen this on some old nursery 

 stock, and on one occasion in Burlington County on an old hedge.
