(male) or a little (female), with the segments near the middle from 

 three to four times as long as wide. The pronotum has the three 

 carinas quite distinct, the two lateral carinae being strongly divergent 

 on the metazone and more nearly approximate upon the prozone than 

 in speciosa. They are most nearly approximate at the second sulcus. 

 All the carinas are cut very near the middle by the principal trans- 

 verse sulcus. 



The tegmina surpass the femora slightly (female) or considerably 

 (male). The ulnar area of the tegmina is usually little or no broader 

 than the intercalary and the latter is occupied even distally by two or 

 more rows of cells. The former is never, as in speciosa, occupied in 

 the male by a single row of cells. 



This species is extremely variable in color, but brown and fuscous 

 are the predominant tints. In some specimens brown is replaced by 

 various shades of green on the face, cheeks, occiput, disk and lower 

 part of the lateral lobes of the pronotum, anal and costal fields of the 

 tegmina. In these and other light colored specimens the fuscous 

 stripe behind the eye is quite broad especially in the male; in many 

 dark specimens, especially in the male, the fuscous stripe expands so as 

 to cover nearly the whole of the lateral lobes of the pronotum; gener- 

 ally, however, there is to be seen more or less of lighter sometimes 

 strongly contrasting color along the anterior and lower margins. The 

 lateral carinje are nearly always sharply outlined with yellowish brown 

 or green which cuts the fuscous band on the metazone. The disk of 

 the pronotum is sometimes dark except for a broad median light stripe. 

 The tegmina are commonly brown and the whole radial field is usually 

 mottled with lighter and darker brown or fuscous. The posterior 

 femora are brown with the outer face more or less infuscated, some- 

 times with traces of transverse brown bands. The posterior tibiae are 

 greenish yellow or obscure brown or plumbeous with the darker basal 

 half interrupted by a somewhat conspicuous light annulus a short dis- 

 tance below the knee. 



When compared with speciosas, the color is more mottled, especially 

 on the sides and in the radial field of the elytra and green specimens 

 are much less common. 



This species can be distinguished from speciosas by the length of 

 the tegmina, by the fact that the antennae are longer than the head 

 and pronotum and little or not at all depressed, by the narrower ulnar 

 area of the tegmina never (in the male) occupied by a single row of 

 cells, by the more compressed prozone and by the absence of the faint
