per cent, of the females in Indiana being brown, and a much 

 smaller proportion of the males being green. The male, when dis- 

 turbed, usually flies bnt a few rods, moving in a circling or zig- 

 zag course, and producing a low but distinct shuffling or rattling 

 noise during the whole of its flight. The female moves noise- 

 lessly and more directly to a greater distance, her flight being 

 often abruptly ended by a headlong dive into weeds or other con- 

 cealing vegetation. 



The more important known synonyms of C. rir'ulifasciata, the 

 names of which have many times been used in American litera- 

 ture when referring to that species, are Gri/Uns ciryinianus Fabr. 

 (1775, 2!>1), Loc-itxlfi hifiixt-trhi Harris (1841, 147), Tomonotus 

 ''iiiinicnminiii Sauss. (18(51, 320) and Locust <t nuliitta Harris 

 (1841, 148). Besides these it has been referred to casually under 

 three or four other scientific names.

"Differs from C. viridifasciata in the less strongly keel-like median 

 carina of the pronotum, in the less acute angle of the caudal margin of 

 the pronotum, in the broader fastigium and in the markedly different color 

 pattern, which is essentially that of C. cubensis." "Green phase. Head, 

 pronotum, pleura, caudal femora, a longitudinal bar on the medio-proximal 

 portion of tegmina, a median and a costal premedian patch on the same, 

 apple-green; remainder of tegmina and venter brownish. * * * * Dorsum 

 of caudal femora marked with 3 patches of clove-brown, the median the 

 largest and triangular in shape; ventral faces of caudal femora black with 

 two whitish bands, one median, the other preapical; caudal tibiae glaucous, 

 the genicular extremity clove-brown with a broad yellowish-white annulus. 

 Wings with the disk yellow. Brown phase. Similar to the green one, 

 except that the green of the latter is replaced with clay-color, ochraceous 

 or ochraceous-buff much marked with clove-brown on the head, pronotum 

 and pleura. Length of body, $ , 18, 9, 24.5; of tegmina, $ , 18, 9, 21.5; of 

 caudal femora, $ , 12, 9, 13.8 mm." (7?. & H.} 



The above are the essential parts of the original description of 

 this southern form. A careful comparison of many individuals of 

 riridifdxdata from Indiana and anstridior from Florida, shows 

 that only one structural character between the two is apparently 

 fixed, viz., that pertaining to the proportional greater width of 

 the vertex in uustnilior. The height of the median carina and the 

 degree of angulation of hind margin of metazona show individual 

 variations, which are as marked in specimens from the north as 

 from the south. Scudder < !X7r>c, 482) set forth in parallel col- 

 umns the differences between New England, Texas and Florida 

 specimens of riri<lif<ix<-i<it<i. and the only structural difference of 

 any note which he gives between the first and last is that pertain-
