632 FAMILY vn. TETTIGOXIID.T;. THE CAMEL CRICKETS. 



form which Scudder described in his last work on Ceutliopliilus 

 (1894, 50) as C. lapidicola Burin. (1838, 723) cannot be distin- 

 guished by any good structural character from what I recognize 

 above as C. gracilipcs. He separates them in his key only by the 

 hind tibiae of male being "at least a tenth longer than hind femora" 

 (gracilipcs) or ''distinctly less than a tenth longer," (lapidicola). 

 The specimens which he set aside in the Cambridge collection as 

 1< />idicohi differ from those of gracilipes only in their general 

 darker hue, the secondary genital characters of both sexes being 

 very nearly the same as those of gracilipcs, the only appreciable 

 difference being that in lapidicola the lobes of the subgenital 

 plate of male are a little more rounded at apex. The original de- 

 scription of both lapidicola and gracilipes are very brief, being as 

 follows: 



"Ph. lapidicola Germ.: Testacea nitida, dorso vitta utrique longitudi- 

 nal! fusco-nebulosa s. marmorata. Long. corp. 10"', ped. post 1%". Aus 

 Virginien uncl Sud- Carolina, 2 weibliche examplare in Germar's Samm- 

 lung." 



"Ph. gracilipes Hald. Shining yellowish-brown, mottled; colors ar- 

 ranged transversely ; limbs longer than in any other American species, the 

 posteriar femora of male being 12 and the tibiae 13 lines, in a specimen ten 

 lines long. This species is from central Pennsylvania and is nearest al- 

 lied to Ph. lapidicola Burm., which extends from eastern Pennsylvania to 

 Georgia. Ph. maculata Harris is allied to the latter, but it has the poster 

 ior tibiae in the male waved at base." 



Haldeman's description is scarcely more distinctive than Bur- 

 nieister's, but it has the advantage of having a certain form applied 

 to it from the time it was made until the present, while no one 

 can tell to what species the two females in the Gerniar collection, 

 described by Burmeister, belong. Scudder and other writers for 

 many years applied Burmeister's name to the form herein recog- 

 nized as C. terrestris Scudd. It is better, therefore, to drop the 

 name lapidicola from our lists until the species to which it was 

 originally applied can be correctly identified by an examination 

 of the types, if they still exist. 



The C. pallidipes Walker (1905, 115) is, as E. & H. (1916, 272) 

 have shown, only a small dark form of what they recognize (fol- 

 lowing Scudder) as G. lapidicola Burm. Specimens of this form 

 are at hand from various points in Michigan, some of them re- 

 ceived from Hubbell as C. meridional-is Scudd. (1894, 66), de- 

 scribed from Chihuahua, Mex. An examination of the type of 

 that form at Cambridge shows that it is at the most only a south- 

 western race of gracilipes.
