nearest colonies known arc on the border of Lenox and Stockbridge, 

 Mass., and at Great Barrington. The first named is practically ex- 

 terminated and the other on the verge of extinction. It is extremely 

 important that these infestations be detected early and the insects 

 destroyed if possible, otherwise the State of New York will soon have 

 a serious gipsy moth problem comparable to that of the New England 

 States. 



Norway maple leaf hopper (Alebra albostriella Fall.) . 

 The Norway maple is comparatively free from injurious insects and 

 the reported severe injury to foliage by a leaf hopper was therefore 

 unexpected. Mr F. A. Bartlett of the Frost & Bartlett Company, 

 states that Norway maples in the vicinity of Stamford, Conn., are 

 frequently seriously injured by this species, many leaves dropping 

 in midsummer. Similar conditions were found to obtain in New 

 Jersey' in the vicinity of Morristown and also at certain Long Island 

 localities. Under date of July 23, 19 14, Mr Clinton C. Lawrence 

 forwarded from Newburgh, N. Y., an excellent series of this species, 

 together with leaves which showed severe and characteristic leaf 

 hopper injury. 



This small leaf hopper is only about one-eighth of an inch long and 

 so far as specimens in the State collections are concerned, is mostly 

 yellowish or yellowish orange. It is about the same size as the 

 whiter and much better known rose leaf hopper and presumably 

 has somewhat the same habits, though records concerning its life 

 history and food plants are lamentably scarce. This leaf hopper is 

 evidently quite variable, as it has been described under no less than 

 seven different names in Europe and four in this country. It has 

 been recorded in America from Canada south to Washington and 

 west to Illinois and Michigan. Mr E. P. Van Duzee captured 

 specimens at Hamburg, N. Y., " sweeping ferns and rank weeds," 

 and it has been reported as occurring on pear and cherry. Melichar, 

 in his work on the Cicadas of middle Europe, states that this 

 species is quite abundant on oak. State Museum material indicates 

 the occurrence of adults during July and August at Jamaica, New- 

 burgh, Kingston, Phoenicia and Ausable Lake. These data, taken 

 in connection with what is known of the insect, indicate a wide and 

 general distribution. 



This species was first recorded in America in 1 864. It probably sub- 

 sists for the most part upon comparatively valueless plants, though 

 the above-mentioned injury indicates a probable change in food 

 habits and the possibility of it becoming of considerable economic 

 importance. Mr Bartlett states that last year he was able to con-
