Lastly, by what means the migrants were enabled to follow one 

 another so unerringly upon their journey we have no means of learn- 

 ing. A possible clue to the situation lies in the fact that both sexes

 grance of violets, [f we assume that from hour to hour, nay even 

 from day to day, sufficient of this fleeting perfume lingered in the 

 air to show the way to succeeding but terflies, then we are confronted 

 by a wonderful phenomenon indeed.

THE NEW PEACH MITE Prof. Johnson's note in December 

 EXTOMOLCK AI. XKWS and Prof. Webster's in January remind me 

 that it may be interesting to note that the peach mite, to which 

 Mr, Johnson refers, is quite widely distributed in the United States. 

 It was first pointed out to me by Prof. Waite. After that I found 

 it at the following stations in Florida: "Macclenny, Glen St. Mary. 

 DeFuniak, Lake City, and, very recently, at Cocoauut Grove. It 

 also occurrs in the Missouri Botanical Garden on an almond-tree. 

 The effect is the same as in the case of the peach-tree, causing what 

 may be termed a silvering of the leaves. While attending a meeting 

 of the Georgia Horticultural Society I found it at Savannah, in 

 '97. and a >'e.ir later at Columbus. It occurs also on the peach-trees 

 of the Experiment Station ot Georgia, at Experiment, Ga , and at 

 the Iowa Experiment Station, at Ames, la. It is also found in 

 Eastern Iowa, at Le Claire. These observations stretch over a 

 considerable time and likewise over a considerable area. I think 

 the mite may occur in any section where the almond or peach is 

 growing. In Florida it rarely causes any perceptible damage to 

 nursery stock, from the fact that as soon as the rainy season sets 

 in the mite is almost eradicated. As Prof. Johnson is making a 

 study of this mite, I thought it would be interesting to note it- 

 occurrence . 



Another mite, which seems to belong to this same genus and U 

 possibly the same species, occurs on rose leaves, causing on these a 

 somewhat metallic appearance' P. II Hoi.i s.
