cles and are pilose. The egg is usually mere or lesf flattened above 

 and striate, being thus different from the glistening spherical egg of T. 

 himaculatMs . There may also be seen a short erect column arising 

 from the upper surface which ii usually about equal in length to the 

 diameter of the egg. The tarsi are provided with long hook-like claws, 

 which are lacking in himaculatus . Other microscopical features are 

 also shown in Fig. 7, 1-10. 



The mite is still more unlike the clover TnitQ,Bryohia pratensis, since 

 the latter is much larger, dark bluish or piu"ple in color when adult and 

 is provided with a nimiber Df plates around the margin of the body. 

 The egg of the clover mite is also larger than the red mite, being .19mm. 

 in diameter instead of .15; and does not possess the central stalk. 



Occurrence in Connecticut and Elsewhere 



This is the first record of the appearance of the mite in Connecticut 

 but it was noticed in Pennsylvania in 1919,^ by Caesar^ in Ontario in 

 1915, and has been studied extensively in Sweden by Tragardh^ in 

 1915. It was originally described from Italy in 1877-8 and probably 

 has a much wider distribution than indicated here. 



In Connecticut it has been found in New Haven, North Haven, Bran- 

 ford, Milford, Meriden, Middletown, Greenwich and Danbury. 



Common Names Used for the Mite 



Tragardh calls it the fruit-tree spinning mite, Caesar the European 

 plum mite, while in Italy it is known as the rose mite. The name 

 used in this paper is merely a descriptive title and should not be fol- 

 lowed unless passed upon by the nomenclature committee of this society. 



Nature of Injury to Host 



Thus far it has been taken in Connecticut on apple, cherry and rose, 

 but has not been collected from plum. On apple the most noticeable 

 effect of the infestation is a browning of the foliage, but some trees as- 

 sume a dull leaden appearance. Late in summer the trees lose a good 

 many leaves, and the size of the fruit appears to be affected. Thus
