SYNONOMY 



The generic name, Phylloscelis, was given to this insect in 1839 

 by Germar 7 who described two species from a collection of two 

 specimens, both of which had short wing covers and abortive wings. 

 In 1907 Van Duzee s described the alate forms of both species basing 

 the distinction of the two on the venation of the elytra. Osborn ° 

 in 1904 described the alate form of P. atra illustrating the venation 

 of the wings. 



In our collections of this insect we have obtained specimens that 



not only accord with the descriptions of atra and pallescens but 



others also that are intermediate forms between these species. We 



are not stating positively that only one species exists, but until 



more marked and constant characters can be found for separating 



the different forms we see no reason for listing them as separate 



species or for separating the insects into varieties. Since Mr. Van 



Duzee has pronounced the specimens sent to him as P. atra, we 



have retained that name.
