Orchelimum campestre Blatchley. 



This insect, of less than medium size, with narrow and al- 

 most uniformly wide tegmina. with the posterior femora 

 unarmed beneath, and with a short and narrow ovipositor, 

 has been reported from the south-eastern part of the state, 

 but no specimens have been seen by the v^riter. 



Orchelimum nigripes Scudder. 



THE BLACK-LEGGED GRASSHOPPER. 



Somewhat smaller than vulgare ; the body moderately 

 robust. Pronotum short, the posterior lobe, especially in 

 the male, rather strongly upturned. Tegmina a little shorter 

 than the wings, surpassing slightlj^ the hind femora. The 

 shrilling organ of the male is unusually large and prominent 

 with strong cross veins, and behind it the tegmina taper 

 rapidl}' on both margins ; their shape and the size of the 

 tympanum causing the male to appear somewhat peculiar 

 and much more robust than it really is. Hind femora armed 

 on apical half of lower outer carina with from one to four 

 small spines. Cerci of male slender, tapering, the apex a 

 little obtuse; the sub-basal tooth long, slender and a little 

 curved. Ovipositor rather long, broadest in the middle, 

 tapering to a delicate point. The males vary much in size. 

 General color green or reddish-brown, the former prevailing 

 in the male, the latter in the female. Occiput and disk of 

 pronotum with the usual brown markings. Front and sides
