without in any way holding on to them. Whether this position is 

 intentional or not, I cannot say, but certain it is that when looked 

 for from above they offer the smallest extent of their bodies to 

 view and may thus escape many enemies." 



Hart (1907) records robust us as occurring on waste sandy land 

 in central and southern Illinois, and has observed them resting, 

 head downward, on a green stem, thus closely resembling a grass 

 leaf. At Tappahannock and Charlottesville, Va., Fox (1917) 

 found robustits frequent on dry land or at the borders of tidal 

 marshes, occurring on tall grasses and herbage in fields, pastures 

 and roadsides. 



238a. NEOCONOCEPHALUS ROBUSTUS CREPITAXS (Scudder), 1862, 450. 



Crepitating Cone-head. 



Size very large for the genus; form very robust. Color of robustus, 

 the brown form more often found than there. Differs mainly in the 

 shape of the fastigium which is distinctly broader, but feebly narrowed 

 on apical third, and with tip bluntly rounded (Fig. 169, g. ) Disk of pro- 

 notum broader, that of female with lateral carinse parallel or nearly so 

 not feebly divergent as in robiistus. Hind femora proportionally longer, 

 with spines of lower carinae longer and more slender. Length of body,

Vigo Co., Ind., Aug. 8, one male; St. Louis, Mo.; Sedgewick 

 Co., Kansas, August, taken at electric light by E. S. Tucker. In 

 addition to the single A^igo Co. male this form is known from In- 

 diana only from Lake Maxinkuckee (R. & H., 1915, 394) and from 

 Tippecanoe County, where Fox (1915) took two specimens in the 

 corn plats of Purdue University farm on August 26. 



In Florida it has been recorded from Warchard, Levy Co., At- 

 lantic Beach, Hastings and Fort Barrancas. Scudder's types of 

 crepitans were from Texas and Nebraska and its range is given 

 by R. & H. (1915, 392) as extending from ''extreme southern New 

 Jersey over the entire coastal plain of the southeastern United 

 States as far south as Hastings, Fla. Westward it is widely dis- 

 tributed over the entire Mississippi Valley region as far as White 

 Bear Lake, Minn.; Garden City, Kan.; Clarendon and Cisco, 

 Texas, and Nugent, Miss." They state (1915, 3S9) that in the 

 vicinity of Ocean View, N. Jer., and on the Delaware River near 

 Philadelphia intergrading specimens between V. robustus and V. 

 crcpitans occur and on the basis of this intergradation they place 

 <> -('/titans as a race of robustus. 



Davis (1913, 178) states that at Erma, N. Jer. the song of 

 crepitans (so-called by R. & H.) ''while it consisted of the same
