strong teeth. General color a bright pea-green, the shrilling organ of 

 male brownish with a heavy green cross vein. The abdomen yellowish 

 or brownish green. 



Measurements : Male — Length of body, 21 mm.; of tegmina, 38 mm.; of 

 posterior femora, 30 mm.; of pronotum 6.5 mm. Female — Length of body, 

 23 mm.; of tegmina, 36 mm., of posterior femora, 31 mm.; of ovipositor,

This species is rather common throughout the state from August 1st to 

 October, frequenting the shrubbery along fence rows and the edges of 

 thickets and woods, especially in damp localities ; and when flushed, flies 

 with a kind of whirring noise, alighting on fence or the lower branch of 

 tree. I have not distinguished the note made by the male, but McNeill 

 (he. cit.), says that it is a " quick, shuttling sound which resembles " Katy " 

 or " Katydid " very slightly." 



aa. Tegmina less than 30 mm. in length ; sometimes reaching but not 

 exceeding the tip of posterior femora. 

 b. Greatest breadth of tegmina contained less than three times in 

 their length ; ovipositor strongly curved.
