24: THE SPECIES OF THE GENUS MELANOPLUS. [Jan. 15, 



half, the upper angle of the apex prolonged and often 



subacuminate (Femur-rubrum series). 



^. Distal half of male cerci much less than half as 



broad as the extreme base ; interspace between meso- 



sternal lobes of male nearly or quite twice as long as 



broad ; tegmina usually surpassing the hind femora. 



/i^. Pronotum marked above with light carina! 



streaks on a dark ground ; tegmina dark olivaceous 



green plumbeus. 



h^. Pronotum uniform in coloring above ; tegmina 

 dark fuscous. 



V-. Furcula not reaching or scarcely reaching the 

 middle of the supraanal plate. . . .femur-rubrutn. 

 i"^. Furcula extending considerably beyond the 



middle of the supraanal plate propifiquus. 



g"^. Distal half of male cerci distinctly more than half 

 as broad as the extreme base ; interspace between 

 mesosternal lobes of male scarcely if at all longer 

 than broad ; tegmina usually falling far short of the 

 tips of the hind femora. 



h}. Apical margin of subgenital plate not elevated 

 where it joins the lateral margins, so that it is 



straight as seen from behind extremus. 



h^. Apical margin of subgenital plate elevated tO' 

 form a tubercle where it joins the lateral margins,. 

 so that it is broadly notched as seen from behind . . 



monticola. 

 c^. Cerci of male more or less expanded apically, so as to be 

 broader at some point beyond the middle than at the middle, 

 spatulate or subspatulate or apically bifurcate. 



//^ Cerci of male simply spatulate or subspatulate, at most 

 moderately broad, apically entire and no broader than at 

 base ; furcula always developed as distinct denticulations, 

 generally as long or very long ones. 



<?\ Furcula of male long and prominent, the projecting 

 portion much longer than the last dorsal segment from 

 which it springs, generally more than a third as long as- 

 the supraanal plate. 

 /\ Subgenital plate of male only moderately broad at 

 apex, distinctly narrower than long, never in the least
