Forty- FOURTH Report on the State Museum 



name and description by Professor Garman, in the year 1886. 

 Recently, it has been studied at the Entomological Division of the 



U. S. Department of Agriculture, 

 and a valuable paper upon it has just been 

 published by Dr. Riley and Assistant 

 Marlett of the Division, to which the 

 reader is referred for its life-history and 

 all other needed information of it. The 

 paper is illustrated by carefully executed 

 figures, which, by permission of the 

 Division, we are permitted to present 

 herewith. 



Distribution. 

 It appears froin the above paper that 

 the mite has been identified in its eggs 

 Bkyobiapratensis. occurring upon the apple, plum, cotton- 



wood, and almond trees, from several localities in California. It has 

 also been observed in Oregon, Montana, and Utah, and to the eastward, 

 in Iowa, Indiana, Illinois, Ohio, New York, Massachusetts, Rhode 

 Island, and District of Columbia.

Food-plants. 



The paper further represents it as being a very general feeder. 

 "Many of the trees on which it has been found, however, evidently 

 serve but to furnish winter-quarters, and are not especially attacked 

 by the young and adults during the summer months." 



"Of the forage plants, clover and timothy are especially attacked; 

 the former being perhaps the ordinary food-plant of the mite. Of 

 trees, the apple and arbor- vitse are frequently infested with all stages 

 during summer, and the occurrence of eggs and adults in autumn 

 and winter on almond, plum, prune, poplar, elm, and other trees, 

 would indicate that these are also attacked." 



Occurrence at Schodack Center, N. Y. 



In my Sixth Report, several appearances of the mite in New York 

 and other States, are recorded. The following was brought to my 

 notice during the month of August of the present year, in this 

 inquiry, from a correspondent at Schodack Center: 



Will you please answer the following in relation to the mite that 

 has appeared the past week in a barn-yard here, and oblige many who 

 are interested in it. The insect is so small that it would hardly be 

 discernible to the* naked eye, were it not for its color, which is a beau-
