ternal lobes are separa:ted by a space about twice as long as broad in 

 this species, in spcciosa by a space about as long as broad. In some 

 respects decora approaches O. orizahcB, but it is readily distinguished 

 from that species by the very much shorter vertex and the parallel 

 lateral carinas of the pronotum.

Scutellum of the vertex extending in front of the eyes much less 

 than the distance between the eyes, with the sides meeting at an angle 

 scarcely so little as a right angle even in the male. A somewhat 

 crescent-shaped sulcus extends across the scutellum and this is inter- 

 rupted by a faint median carina which extends backward more or less 

 distinctly to the middle of the occiput. The lateral foveolse are 

 usually indistinct and triangular. The frontal costa has the sides 

 slightly and somewhat regularly diverging from the vertex to the cly- 

 peus ; it is furnished with coarse lateral walls which are moderately 

 high or scarcely elevated. The eyes are distinctly less than twice as 

 long as the groove below the eye. The antennae are about as long as 

 the head and pronotum ; they are plainly depressed with the segments 

 near the middle from one and one-half to twice as long as broad. The 

 three carinas of the pronotum are distinct raised lines, cut slightly be- 

 hind the middle by the principal sulcus. The lateral carina are gently 

 sinuate and convergent to the second sulcus on the prozone and only 

 slightly divergent on the metazone. 



The tegmina are rarely longer than the abdomen in the female and 

 they very rarely surpass the knees in the male. The ulnar area is 

 usually twice as wide as the intercalary area in the middle of the elytra 

 and is furnished with one (male) or two (female) rows of cells. The 

 intercalary area has but a single row of cells at the distal end 



The color is extremely variable. Some specimens are a nearly uni- 

 form dark brown ; lighter colored specimens have the ground color 

 any shade of brown or green, sometimes varied with rose, with a rather 

 broad fuscous stripe extending from the eye across the upper margin of 

 the lateral lobes of the .pronotum, on the metazone crossing the lateral 

 carinse and edging the disk. In many specimens the lateral carinas
