Some New Insect Enemies of Greenhouse and 

 Ornamental Plants in New Jersey 1 



With the exception of Leptobyrsa rhododendri Horv. and Neo- 

 borus amoenus Rent., all of the insects mentioned herein have only 

 recently been found inhabiting New Jersey. The two exceptions 

 have been known to exist in New Jersey for some time, but hereto- 

 fore, very little has been published concerning their activities in this 

 state. 



The Ash Leaf Bug 



Neoborus amoenus Reut. 2 (Fig. 1, 2, 3) 



This species was described by Reuter 3 in his paper "Bemer- 

 kungen iiber Nearctische Capsiden nebst Beschreibung neuer Ar- 

 ten", where it appears under the name Tropidosteptes amoenus, 

 Reuter adopting the manuscript name of Professor Uhler. 



In Van Duzee's 4 check list of the "Hemiptera of America, 

 North of Mexico", it appears as Neoborus amoenus Reut., with 

 saxeus Uhl., as a name cited in error, and the following varieties, 

 palmeri Reut., plagiata Rent., signata Rent,, and scutellaris Reut. 

 In the same list, its distribution is given as Canada, Eastern states 

 to the Mississippi Valley and eastern Canada. In Smith's "Insects 

 of New Jersey", 5 it is recorded from New Brunswick on ash. It 

 has however, a much wider distribution in New Jersey, having been 

 found at Somerville, Milburn, South Orange, Kingston, Springfield, 

 Irvington, Rutherford, Morris Plains, and Elizabeth, and is un- 

 doubtedly a well-distributed species.
