556 FAMILY VII. TETTIGONIID.E. THE KATYDIDS. 



England and Ontario west to northern Michigan, southeastern 

 Minnesota and central Montana and south and southwest to Flor- 

 ida, Mississippi, central Texas and New Mexico. 



In Florida it has been taken by me at Dunedin in December 

 and January from tall grasses about the margins of shallow ponds 

 where it occurs in company with Leptysmu imirginicoUis and Con- 

 ocephalus gnu-HHmns. It has also been recorded from scattered 

 localities throughout the State, but the adults were usually scarce, 

 though Hebard (ll)lob) says that "In July the marshes of the 

 region about Miami swarm with the young." 



Under the name of 0. uullnnense Walker (1905, 37) recorded 

 it as common in August near Sarnia, Out., in a large tract of 

 open grassy laud, and also as found in marshes at Aruer and on 

 Walpole Island. R. & H. (1915a, U5) state that: "From the east- 

 ern States we know of no correct record of the occurrence of the 

 species at a locality away from the general vicinity of the coast." 

 In Virginia Fox found it abundant among the grasses and sedges 

 of the tidal marshes. 



254a. ORCIIELIMUM CONCINNUM CAMPESTRE Blatchley, 1893c, 91. 



Differs from typical concinnum in its slightly larger, more robust 

 form, generally paler color, the ground hue being more often green than 

 pale brown, uniform green face, longer, more narrow and less tapering 

 tegmina and relatively longer and more slender hind femora. Length of 

 body, $, 17.5, .2, 19; of antennas, 46; of pronotum, $, 4.24.5, $, 4.55; 

 of tegmina, $, 2124, $, 2025; of hind femora, $, 1617, 9, 1617.5; 

 of ovipositor, 7 7.5 mm. 



While this form agrees with coiic'mnuin in the size and shape 

 of the male cerci, it differs sufficiently in the characters given to 

 justify at least a varietal name. In Indiana it is frequent as far 

 south as Knox County, inhabiting for the most part upland blue- 

 grass pastures and the tall grasses of the dryer prairies and being 

 seldom, if ever found about the lakes and marshes in company 

 with typical concinnum. I have taken it at Buffalo, N. Y., on 

 Sept. 4, and it has been definitely recorded from Ontario, Ohio, 

 New Jersey, Illinois and Minnesota. It is also known (Fox Ms.) 

 to occur near C larks vi lie, Tenn. 



254b. ORCIIELIMUM CONCINNUM DELICATUM B rimer, 1892a, 264. Delicate 



Meadow Grasshopper. 



Smaller and more slender than 0. concinnum. Color much the same, 

 the face without a dark stripe. Pronotum shorter and narrower, the hind 

 margin of metazona more rounded; lateral lobes less deep, the humeral 

 sinus more evident. Stridulating field narrower, the cross-vein shorter, 

 more slender. Subgenital plate of male narrower, more strongly keeled be-
