siderable numbers, late in September, which I have sent to several 

 correspondents in Europe who have written me that they were quite 

 unlike anything there. These proved to be like the slate-colored 

 and red mixed form mentioned above, except considerably 

 larger; I can see no difference except in size. There is no cran- 

 berry growing where these are found, but other related plants, as 

 blueberry, upon which they might have fed. My impression is 

 that they hibernate in the imasjo state, but of this I am not sure. 

 A few years ago I received several specimens from Mr. G. M. 

 Dodge of Glencoe, Neb., 'bred on wild rose,' which are so like 

 those taken here that I could separate them only by their greater 

 depth of coloring and their much larger size, for they are as much 

 larger than those taken here, as these are larger than those from 

 Prof. Eiley and others from Texas. I received T. minuta from Mr. 

 Dodge, and also from Mr. Morrison, taken in Nevada, and they 

 also were unusally large. I am, therefore, inclined to believe 

 them all the same species, but I am not yet ready to concede that 

 oxycoccana is the same thing. It will be better to allow it to 

 remain separate till it can be proved to be the same, rather than 

 to unite them now, and separate them later, should they prove 

 distinct. 



"The synonymy is as follows: 



Teras mimda. 



Tortrix minuta, Robs., 1869. 



Tortrix malivorana, Le Baron, 1870. 



Tortrix vacciniivorana. Pack., 1870. 



Teras variolana, Zell., 1875. 

 "The above are the orange forms. 



Tortrix Cinderella, Riley, 1872. 



"Riley's name may be used to indicate the slate-colored form. 



Robinson's T. minuta was published in February, 1869, and 

 Packard's T. oxycoccana not until April, 1869." 



The species next attracted attention during 1883 and '84 by its 

 extraordinary abundance in nurseries in McLean county, Illinois. 

 Prof. S. A. Forbes called attention to the outbreak in a paper 

 read before the State Horticultural Society in 1884, (Transactions, 

 p. 124), stating that thick-leaved trees were relatively little 

 affected, but that all the others were so seriously checked in their 

 growth as to excite 'the serious apprehension of the owner. As 

 to remedies. Prof. Forbes stated that "methods of precaution must 

 be the main reliance," and also recommended that the foliage be 

 sprayed with arsenk^fCt mixtures early in the season, when the 

 injury is just beginning. 



Similar observations concerning the same attack were published 

 in the Fourteenth Report of the State Entomologist of Illinois.
