This dull coloured grasshopper has been found in small numbers in 

 both Vigo and Fulton counties, in upland prairie meadows, where it 

 frequents the tall grasses, usually in company with Xiphidium strictum, 

 Scudder. 



It is a smaller and more slender bodied insect than the common O. 

 vulgare, Harris, and has a shorter and narrower pronotum and a much 

 smaller ovipositor than that species. 



Orchelimum Bruneri, nov. sp. 



A species of about the same length, but less robust than O. vulgare, 

 Harris, having the posterior femora armed beneath, and the ovipositor 

 very broad, nearly straight and of more than average length. 



Cone of the vertex narrow, moderately elevated, rounded at apex. 

 Tegmina long and narrow, a little shorter than the wings. Posterior 

 femora rather stout, the apex, when appressed, not quite reaching the tip 

 of ovipositor ; armed beneath on the apical half with three or four small 

 spines. Cerci of male stout, acuminate, with the internal tooth prominent. 



Ovipositor very similar to that of O. gladiator, Bruner, being very 

 long and stout, nearly straight above, and with the under side of apical 

 third sloping rapidly to the acute apex. 



Colour of dried specimens. — With the exception of the ovipositor, 

 which is a light reddish-brown, and the usual stripe on occiput and disk 

 of pronotum, the whole body is a pale, transparent brownish-green, the 

 green showing plainly only on the lower half of the side of pronotum and 

 on the meso and metapleura. The reddish -brown dorsal stripe of occiput 

 and pronotum is bordered laterally throughout its entire length with a 

 very narrow one of much darker brown. When immersed in alcohol the 

 reddish-brown stripe fades to a yellowish white, leaving the two lateral 

 ones as prominent dark streaks, widest on the central portion of the 

 frontal disk.
