Key to the Species of Campylacantha. 



A 1 . Distal half of anal cerci of male less than half as broad as the extreme base. 



b 1 . General color griseous, sometimes a slight greenish tinge, hind tibia livid, finely 

 flecked with griseous acttlipennis. 



b-. General color olivaceous; hind tibia yellowish green olivacea. 



A 2 . Distal half of anal cerci of male more than half as broad as the extreme base, .vivax. 



Campylacantha acutipennis Scudder. 

 Our specimens agree remarkably well with Scudder's description, and 

 vary only slightly, as follows: Antennae pale yellowish testaceous, some- 

 times becoming infuscated at the extreme tip; median carina distinct, 

 the lateral carina more distinct on the metazona than on the prozona.

 Campylacantha olivacea Scudder. 



General color varies from rather bright to dark olivaceous green. 

 The antennae are greenish at the base, sometimes mottled with brown; 

 beyond the base they are orange to ferruginous, infuscated at the tip. 

 The darker forms have very little of the lemon-yellow marking on the 

 pronotum; pronotum dusky. Legs yellowish green to dark olivaceous, 

 rarely tinged with orange; cerci slender, feebly incurved, the apical half 

 about half as broad as the basal half.
