Description. — Much smaller than fuligimmi and very distinct from 

 that .species. Head and pronotum essentially as in ftiliglnosa., except 

 that the pronotum is scarcely at all elevated posteriori}', while this is 

 only true of some specimens oifuHginosa. Legs as mfHJiglitox((^ the 

 anterior femora with a few short s})ines on the inner inferior carina, 

 the outer margin unarmed or sometimes with infuscated spots repre- 

 senting si)ines, in the nymphs with more distinct 

 spines. Elytra generally more slender than com- 

 mon in y>iI/'gif>o.s<t^ but with the same general color 

 pattern, the ol)lique discal spots sec^mingly a little 

 less elongate; wings shaped as in fuI/)/inosa., ))ut 

 difi'ering radically from those of that species in IxMng 

 transparent instead of fuliginous, the costal l)order 

 onlv suhopaque. Last abdominal segment with the „ ,„ „ 

 anal prolongations not quite as elongate as in occidentaus. cekcus 

 fuHgmos^i,at least in the male; cere i of the male "^ ^«^ ^^i-^- 

 much shorter than those oi fnltg/udsa., being a))out four times as long 

 as the basal breadth and apicalh' armed on the inner side with a very 

 short l)lunt spur, often a mere shoulder, and subapically with a long 

 well-developed tooth or spur (tig. 23). Ovipositor curved gently 

 downwai'd and somewhat variable in length. 



Color similar to that of fuUguiosa^ ])ut usually more bleached in 

 cabinet specimens, being of a fawn color. The wings are nearly 

 transparant, not fuliginous as in fitVtginom. There are two color 

 varieties, both green,
