SUBFAMILY IV. CONOCEPHALIN^E. 561 



Walker (1905, 38) found aohi-ntmn very abundant in southern 

 Ontario where it occurs among the rushes and tiayitturlu, growing 

 in open marshes bordering the streams. He says : "McNeill has 

 well represented its song, but I have never noticed the preliminary 

 ziji-.:ip." 



259. OKCHELIMUM BRADLEYI Rehn & Hebard, 1915a, 73. Bradley's Meadow 

 Grasshopper. 



Very similar to 0. volantum. Differs in its larger size, with fore and 

 middle femora more distinctly tapering and basal two-thirds of hind fe- 

 mora more swollen. Male with cercus differing as described in key, the 

 dorsal surface of the shaft inflated near middle and with a curved carinate 

 ridge on basal half. Ovipositor more than half the length of hind femora, 

 its apical half gradually narrowing to apex; upper margin nearly straight, 

 the lower one straight from base to middle (Figs. 183, 184, g.) Length of 

 body, $, 23.225, 9, 21.5 23.6; of pronotum, $, 4.8 5, 9, 4.95.2; of 

 tegmina, $, 25.7 27.7, 9, 2628.9; of hind femora, $, 1920, 9, 18.9 

 21.2; of ovipositor, 10.411.5 mm. (Fig. 187, c.) 



Dunedin, Fla., June 10 (W. 8.B.) ; Wilmington, X. Car., Aug. 

 1 (Daris.) Ranges from southeastern North Carolina south to 

 central western Florida and inland as far as the Okeefenokee 

 Swamp of southern Georgia. In Florida it is known only from 

 Jacksonville, Tallahassee and Dunedin. Dr. J. C. Bradley, who 

 collected the types, furnished the following notes to E. & H. re- 

 garding their habits: 



"In the eastern half of the Okeefenokee Swamp are extensive so-called 

 prairies. These are really inundated plains grown up with sawgrass and 

 maiden-cane, or in places open shallow lakes covered with a multitude of 

 water plants. The natives of the Okeefenokee told us of diving grasshop- 

 pers which lived on these prairies, and in making the trip to the Chase 

 Prairies in September, 1913, I found these grasshoppers in great abundance 

 in the grass-like plants growing out of the water or along the banks of the 

 old canal. As the boat approached them they jumped from the grass into 

 the water, completely disappearing, and so quick were they to do this when 

 alarmed that it was only after some difficulty that I succeeded in catching 

 a series of specimens." 



This aquatic habit is also recorded by Engelhardt 68 who says : 

 "Of interest is the aquatic habit of Orchelinnnii roltnituin which 

 was abundant about the grassy borders of Greenfield Pond near 

 Wilmington, N. Car. When pursued and hard pressed it would 

 dive into the water and cling to the submerged grass stems or 

 the under side of a water-lily leaf, where it remained for several 

 minutes, sustained by a supply of air which showed in glistening 



8s .Tourn. N. Y. Ent. Soc., XVIII, igio, 130. The first records of O. bradlcvi. R. & H. 

 (igM) and Sherman and Brimley (1911) were made under the name of i'i>lantnm 

 McNeill, to which it is very closely allied and of which it may prove to be only a 

 southern race.
