pecially in the female, but little narrower than posterior ; the lateral 

 carinse somewhat rounded. The ovipositor is more curved and more 

 strongly serrate than in either the preceding or the following species. 

 The color is essentially the same as that of dbhngifolia. 



Measurements : Male — Length of body, 19 mm.; of tegmina, 27 mm.; of 

 posterior femora, 25 mm.; of pronotum, 5 mm.; width of tegmina. 10 mm. 

 Female — Length of body, 20 mm.; of tegmina, 27 mm.; of pronotum, 6 mm.; 

 of ovipositor, 10 mm.; width of tegmina, 11 mm. 



As far as my observation goes, rotundifolia is, by far, the most common 

 member of Amblycorypha found in Indiana. It is more of a terrestrial 

 species than the preceding, being often seen on the ground, or on the 

 clumps of tall grass and weeds, which grow in damp ravines. Its flight is 

 comparatively noiseless and less prolonged than that of dblongifolia. In 

 Central Indiana it makes its first appearance about the fifth of August. 

 Of its note, Mr. Scudder says: " This insect stridulates both by day and 

 by night, and without variation. The song consists of from two to four 

 notes— sounding like chic-a-chee, repeated rapidly so as to be almost con- 

 founded, and when three requiring just one third of a second ; the song is 

 repeated at will, 'generally once in about five seconds, for an indefinite 

 length of time."

Our smallest species of the genus measuring but about 27 mm. to end 

 of tegmina. Posterior femora armed as in rotundifolia, slightly exceeding 

 the tegmina in both sexes. Pronotum narrower in front, the anterior 

 half of lateral carina' rounded, the posterior, rather sharp. The male 

 with longer wings and narrower tegmina than the female. Ovipositor 

 less curved than in either of the other species, the apical half with com- 

 paratively strong serrations on both margins. General color, alight, grass 

 green. 



Measurements : Male — Length of body, 14 mm.; of tegmina, 23.5 mm.; of 

 hind femora, 20 mm.; of wings beyond tegmina, 5 mm. Female — Length of 

 body, 17.5 mm.; of tegmina 20.5 mm.; of hind femora, 21.5 mm.; of wings 

 beyond tegmina, 3 mm.; of ovipositor, 8.5 mm.
