numbers of crickets are materially reduced by summer applications 

 of these poisons. Both of these measures — clean culture 

 and spraying with arsenicals — are fortunately standard orchard 

 operations which are invariably practised by the most 

 successful fruit-growers. 



THE NARROW-WINGED TREE CRICKET. 



(Ecanthus angustipennis Fitch. 



historical notes. 



This species was first described by Fitch * as a variety of niveus 

 from a single male specimen. The description is very brief and the 

 only distinguishing character mentioned is the narrow wing covers. 

 Beutenmuller 2 says that this characterization " applies equally 

 as well to quadripunctatus as to the insect determined by recent 

 writers as angustipennis. Whether the latter has been correctly 

 determined or not can never be definitely ascertained, as Fitch's type 

 of the species, as well as all his other species of (Ecanthus, have been 

 destroyed. I would propose that the name angustipennis neverthe- 

 less be retained for the species so well known to us by this name." 

 This species is not generally as familiar to economic workers 

 as niveus, although it has somewhat similar habits. References 

 to the insect are largely found in systematic writings, and as regards 

 its life history and habits very little has heretofore been published. 



DISTRIBUTION. 



Our knowledge of the extent of distribution of this species in New 

 York is very limited. It is common in the lake region of the western 

 part of the State and on Long Island, and probably the insect ranges 

 over about the same territory as niveus. It has been recorded in 

 literature from other states as follows: Massachusetts (Faxon), 

 Connecticut (Walden), Georgia, Florida, Texas (Allard), Illinois 

 (Forbes), Kentucky (Garman), Kansas (Tucker), Minnesota (Lugger). 

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

 New Jersey, North Carolina, Florida (Amer. Mus.), Virginia 

 (Schoene), Ohio (Kostir). Of the states mentioned, Minnesota 

 represents the most northern limits of distribution, while Texas 

 appears as the most western area of its occurrence.
