The Key West and Big Pine Key series are uniformly short-winged, 

 while the Homestead and Detroit representations have a far greater 

 proportion long-winged, abbreviate tegmina being present in five 

 females and the same condition approximated in two males. It is 

 probable that environment is the governing factor in regard to 

 tegminal and wing length in this form. 



All of the color phases known for this race are present in the series 

 in hand, the only lot very uniformly colored being the male series 

 from Key West, which are greenish with the usual postocular bars. 

 The females from Key West, however, show three different color 

 phases. 



At Key West this form was common in green herbage or grasses 

 in or near a gumbo limbo forest in company with Orphulella pelidna, 

 while on Big Pine Key it was taken in pine woods undergrowt.h.

Cruciform markings on the dorsum of the pronotum are more or 

 less noticeable in five specimens of the present series. The differ- 

 ences in coloration previously noted^** are found in the series before us. 



Examination of the material shows that Caudell's record of Arphia 

 sulphured from Key West is incorrect, the specimens belonging 

 unciuestionably to the present species. 



At the first three localities given above the species was scarce in 

 the low undergrowth of the pine woods, but at Key West it was well 

 distributed through the scrub and also in the open gumbo-limbo forest.
