SCUDDER — SUPPLEMENT TO A REVISION OF THE MELANOPLI. 205 



ASEMOPLUS Scudder. 



To this supposedly monotypic genus, Walker has added a new 

 species from the same general region as the type. It is wholly apter- 

 ous and hence the generic description needs to be in so far modified, 

 as well as the table of the genera in my Revision (p. 12) where the 

 category ^4- b'- c V^ ^' /' should read: Tegmina rarely absent (instead 

 of always present) ; and further in the final category for Asemoplus 

 (p. 14) the words " when present" should be added afier the word 

 " tegmina." The two species may be separated thus : 



TABLE OF THE SPECIES OF ASEMOPLUS. 



Tegmina normally present ;* abdomen mesially striped above with yellow- 

 ish; male cerci reaching as far back as the tip of the supraanal plate, slightly 



decurved at tip montanus Brun. 



Tegmina wanting; abdomen mesially striped above with black; male cerci 

 scarcely reaching so far back as the tip of the supraanal plate, in no 

 way apically decurved ni/dus Walk. 



*They are sometimes absent from one side or the other, apparently by accident; out of 

 fourteen specimens seen only one had them absent on both sides.
