THE ASH LEAF BUG, NEOBORUS AMOENUS 

 REUT. (HEM.)' 



By Edgar L. Dickerson and Harry B. Weiss,^ 



New Brunswick, N. J. 



This species was described by Reuter, who adopted the manuscript 

 name of Professor Uhler. In his paper, " Bemerkungen iiber Nearc- 

 tische Capsiden nebst Beschreibung neuer Arten," in which the de- 

 scription appears under the name Tropidosteptes amoenus, he states 

 that the above mentioned species is usually placed in American col- 

 lections under the name Neohorus saxeus Dist., the light varieties 

 under the name Neohorus amoenus Uhl., and that it cannot possibly 

 be identical with Distant's species. He further states that in Neo- 

 horus saxeus Dist. (Biol. Centr. Amer. Rhyn. Heter., I, 1884), p. 276, 

 T. XXVI, f. 5) the first antennal joint is pointed out as being longer 

 and dark, the ground color of the beak pitch brown, the femoral joint 

 chestnut brown, etc., and that the North American species must there- 

 fore be known as Neohorus amoenus Uhl., which is very variable in 

 color, extending from the lightest varieties through all the variations 

 to the darkest (see Uhler, Neohorus saxeus, Proc. Cal. Acad. Sc. (2), 

 IV, 1894, p. 264), also that this species is distinguished from the re- 

 maining species of the genus by the light antennae and by the colored 

 tips of the sides of the pronotum, otherwise it conforms with them in 

 all generic characteristics. 



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

 of Mexico, it appears as Neohorus amanus Reut., with saxeus Uhl., 

 as a name cited in error and the following varieties, palmcri Reut., 

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



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

 states to the Mississippi Valley and eastern Canada. Smith in " In- 

 sects of New Jersey " records it from New Brunswick on ash.^ It has

3 It has been found by the authors on the white ash (Fraxinus americana), 

 green ash (F. lanceolata), red ash (F. pemisylvanica ipubescens)), and the 

 English ash (F. excelsior var. pendula).
