488 Report of the Department of Entomology of the 



preventive and remedial measures. 



The similarity in the behavior of angustipennis to niveus in apple 

 orchards suggests that this insect is susceptible to the same measures 

 as outlined in detail for the latter species. 



THE STRIPED TREE CRICKET. 

 (Ecanthus nigricornis Walker. 



This is apparently the insect described by Fitch 1 in 1856 as (E. 

 fasciatus De Geer, but according to Beutenmuller he " erroneously 

 mistook his insect for De Geer's 2 Gryllus fasciatus which is a Nemo- 

 bius." A description at a later date by Walker 3 under the appellation 

 of CE. nigricornis fits the striped tree cricket very well, and 

 for this reason Beutenmuller 4 in 1894 recommended that 

 this name be accepted since Fitch did not really denominate 

 the insect. As stated previously Walsh and Riley considered 

 this tree cricket as a dark variety of niveus. Others have 

 also held that nigricornis and quadripunctatus are varieties of 

 the same species, but in our studies of these two insects 

 we have found constant differences in their habits as well 

 as body characters, which have led us to regard them 

 as quite distinct insects. 



DISTRIBUTION. 



This tree cricket is very common and is widely distributed over 

 New York and throughout the United States. From literature it 

 is recorded as follows: Massachusetts* (Faxon), Connecticut 

 (Walden), New Hampshire (Henshaw), New Jersey (Davis), Ontario 

 (Walker), Tennessee (Morgan), Mississippi (Ashmead), Michigan 

 (Allis), Illinois (Forbes), Minnesota (Lugger), Nebraska (Bruner), 

 Oklahoma and Arizona (Caudell), Texas and Kansas (Tucker). 

 From specimens examined we can record it from the following states : 

 New Jersey and Connecticut (Amer. Mus.), North Carolina (C. L. 

 Metcalf), Ohio (Kostir).
