 Very close to and perhaps only a larger form of 0. vulgarc. The general 

 color is the same, but the brown line on the disk of pronotum is, in the 

 female, more plainly margined with black, while in the male the black 

 dashes at ends of tympanum are larger and more completely enclose that 

 organ. The tegmina of the male exceed the hind femora by about 4 mm., 

 and are exceeded by the wings about the same distance; those of the fe- 

 male are proportionally a little shorter. 



Measurements: Male — Length of body, 22.5 mm.; of pronotum, 6 mm.; 

 of tegmina, 25 mm.; of hind femora, 19 mm. Female— Length of body, 

 23 mm.; of pronotum, 6.5 mm.; of tegmina, 24 mm.; of hind femora, 19 

 mm.; of ovipositor, 8.5 mm. 



Burmeister's original description of this species is very short and not 

 distinctive. It is as follows : " Verticis et pronoti medio fulvo, nigro- 

 marginato; elytris ab alis dimidia linea superatis. Long. Corp., II"'." Bur- 

 meister knew but two species from the United States, and this short de- 

 scription was sufficient for him to distinguish these, but of the twenty or 

 more species now known it is difficult to say just which one he had in 

 mind when he wrote the above. Of the specimens referred to this species 

 I have but three examples. One is from Fulton county, the other two 

 from Vigo. They were taken from tall grass growing near the margin of 

 ponds. Nothing distinctive of their habits is known. 



dd. Tegmina of equal width throughout ; body slender.
