variable in presence or absence and solidarity. The brown extreme 

 is heavily mottled and suffused fuscous on a tawny-olive ground, 

 the dark markings around the lateral carinae of the pronotum strik- 

 ingly velvety black, the markings of the lateral lobes, tegmina and 

 femora not pronounced. Between these two extremes runs a series 

 of about five phases, each sufficiently distinct to the eye to be readily 

 recognizable. In one the color is uniform honey-yellow with almost 

 no markings, another is similar with the dark markings around the 

 lateral carinae velvety black and a narrow postocular bar fuscous, 

 with faint indications of tegminal maculations and a faint greenish 

 wash on the dorsum of the pronotum. Another has the whole pat- 

 tern, i.e., femoral markings, linings on lobes and pleura, dark areas 

 about carinae and very weak occipital lines and tegminal maculations, 

 indicated, but also entirely washed with ochraceous-salmon. 

 Another phase, apparently unusual, as it is seen only in males from 

 Point Isabel and a female from Boot Key, has the markings similar, 

 but is unsuffused and the base color is quite pale, in fact light buff. 

 The last of these phases is near the brown extreme, but it has the 

 tegminal markings decided and the base color somewhat paler. 

 In addition there crops out in three of the phases that peculiar wash- 

 ing of all or parts of the tegmina, and occasionally part or all of the 

 pronotum, with rich purple seen in a number of the species of this 

 very variable group. The type belongs to the green extreme and 

 the allotype is of a brownish phase which predominates in the' male 

 sex. 



Correlating the material by locality for possible color relation to 

 environment is productive of little positive data, as the more extreme 

 color phases are usually from localities represented by uniques or 

 very small series, while the extensive Key West series (thirty-four 

 specimens) shows very great diversity in itself. The pale markings 

 on the lateral carinae of the pronotum, frequently broken mesad, are 

 the most striking constant color feature of the species.
