LIST OF THE COCCIDAE IN THE COLLECTION OF THE 

 NEW YORK STATE MUSEUM 



BY F. T. HARTMAN 



There are in the New York State Museum at the present time, 

 173 species of scale insects, of which 68 are found in New York, 

 41 have been received in exchange from Japan and the others are 

 from widely separated places in the United States. The greater 

 part of these have been received in recent years, but a few date 

 back to the time of Doctor Fitch. Among these are three micro- 

 scopic mounts ofAspidiotus furfurus Fitch, now C h i o n- 

 aspis furfura. Two bear the label: "Female from under a 

 scale, labeled by Dr Asa Fitch as Aspidiotus furfurus, 

 mounted by J. Henry Comstock, 28 December 1880." The third is 

 labeled: " Female from under a scale, labeled by Dr Asa Fitch as 

 Aspidiotus cerasi. It is specifically the same as Asp. furfurus 

 Fitch, J. Henry Comstock, 28 December 1880." There is always a 

 certain amount of material coming in which proves, on microscopic 

 identification, to be one or another of several common and well- 

 distributed forms. Such common species as Gossyparia spuria, 

 Pulvinaria acericola, P. vitis, Lecanium corni, L. 

 prunastri, the plum scale, Chionaspis furfura, the scurfy 

 scale, C. pinifoliae, Aulacaspis rosae, Aspidiotus 

 ostreaef ormis, the San Jose scale and Lepidosaphes ulmi 

 are, like the poor, " always with us." Nine types and seven cotypes 

 are represented and those with microscopic mounts are indicated by 

 the asterisk.
