Color of dried specimens: Tegrnina and wings a transparent whitish, 

 tinged with green on the front or lower longitudinal nerves ; the cross 

 nervules of the latter darker. Sides of pronotum and abdomen, and all 

 the femora, light green ; the tibiae and tarsi of a brownish hue. Face 

 yellowish white, with a dark reddish brown stripe the width of the lab- 

 rum, starting with the mouth and passing upward to the vertex, where 

 it narrows to the width of that organ ; then, broadening on the occiput, it 

 passes back to the front border of the pronotum, where it divides into two 

 narrow streaks, which enclose a whitish area and extend a little beyond 

 the posterior transverse suture, where they taper to an end. Subgenital 

 plate of male yellow. Basal third of ovipositor dark brown, the re- 

 mainder light reddish-brown. 



Measurements : Length of body, male, 17 mm.; female, 17.5 mm.; of 

 pronotum, male and female, 4 mm.; of tegmina, male, 21 mm.; female, 19 

 mm.; of hind femora, male, 14 mm.; female, 15.5 mm.; of ovipositor, 7.5 

 mm. 



This graceful and prettily marked species was found to be quite com- 

 mon among the rank grasses and sedges growing about the margins of a 

 tamarack swamp near Kewanna, Fulton county. It was first taken on 

 August 26th and again on September 24th, when it appeared more plen- 

 tiful than before. It is the smallest and most slender of the nine species 

 of the genus so far known to occur in the state, and its markings are very 

 distinct from those of any of the others. 



aa. Ovipositor straight or nearly so, the under side of apical third tap- 

 ering rather abruptly to a fine point ; its length 10 or more mm. 

 h. Posterior femora smooth beneath.

" In its general structure this species resembles the more robust forms 

 like 0. glaberrimum and 0. concinnum. It differs from these however in 

 having shorter legs and antennae. The posterior femora are rather slen- 

 der ; the cone of the vertex is short and obtuse, with the extreme tip shal- 

 lowly sulcate ; the hind wings are little if any longer than the tegmina, 

 which do not quite reach the tip of the ovipositor. 



" Color, pale transparent grass-green throughout, save the usual mark- 

 ings upon the occiput and disk of pronotum, which are dark brown, on 

 the latter composed of two well defined, narrow, slightly diverging lines.
