Cyclamen Mite 



375 



DISTRIBUTION OF THE MITE 



From the foregoing it will be seen that this mite has quite a wide range, 

 being found as far east as Connecticut and as far west as Washington and

(fig. I). 



Dr. Iv. O. Howard kindly forwarded data on host plants and distribution 

 and placed at the disposal of the writer slides from the Bureau of Ento-

 and study slides which were collected at various greenhouses in Connecti-

Prof. C. R. Crosby, of New York, and Dr. Philip Garman, of Mar54and, 

 have forwarded data on distribution and reported this mite as occurring 

 in greenhouses in those States. Mr. WilHam A. Ross, of Vineland 

 Station, Ontario, Canada, has reported it as a serious pest to cyclamen 

 in the Province of Ontario. Numerous growers throughout the United 

 States have at various times forwarded specimens and suggestions.
