This species has two well-marked color phases, one pea-green, the 

 other dull wood-brown. The males all belong to the latter phase, and 

 have the internal edge of the tegmina and the internal edge of the basal 

 portion of the wings with a rather broad longitudinal bar of dull 

 3^ellowish. 



The following description is of the male, which appears never to have 

 been recorded. 



Size medium; form elongate; surface granulosc. Head somewhat 

 depressed, posterior portion of subequal width; occiput with a very 

 deep longitudinal sulcus ; eyes subovate ; ocelli distinct; antennae equal 

 to the body in length. Pronotum distinctly longitudinal, twice as long 

 as broad ; anterior margin broadly emarginate, posterior margin broadly 

 arcuate, lateral margins bearing a rather acute process anteriorly; 

 transverse sulci two in numl3er, one immediately posterior to the ante- 

 rior margin, the other just anterior to the middle. ]\Iesonotum dis- 

 tinctly tuberculate (a condition shared by the meso- and metasternum 

 and pleura), slender, subequal; median carina rather broad, low. 

 Tegmina subpyriform, apex obliquely truncate; costal field subequal 

 in width; median protuberance very distinct. Wings about twice the 

 length of the head, pronotum and mesonotum together. Abdomen 

 with the seventh and eighth dorsal segments subequal in length, cari- 

 nate, the ninth shghtly shorter than the eighth, apical emargination very 

 deep, expanded, the lateral portions incurved and enclosing the expanded 

 sinus; cerci subequal in width, not quite equal to the ninth segment in 

 length; subgenital opercule reaching to the tip of the eighth dorsal seg- 

 ment, cymbiform, apex narrowly rounded. Anterior femora with the 

 basal flexure moderately distinct, equal to the head, pronotum, meso- 

 notum and tegmina in length; tibiae equal to the femora in length; 

 metatarsi nearly twice as long as the following tarsal joint. Median 

 femora equal to the pronotum and mesonotum in length; tibiae some- 

 what shorter than the femora ; metatarsi about equal to the remaining 

 tarsal joints in length. Posterior femora and tibiae about equal to the 

 anterior in length; metatarsi slightly longer than the remaining tarsal 

 joints. 



General color dull wood-brown, blotched and suffused with dull 

 ochraceous, the limbs obscurely annulate. Tegmina with a spot on 

 the median protuberance and the internal border as well as the adjoin- 

 ing portion of the wings dull yellow; posterior field of wings vinaceous. 

 Antennae dull brownish-ochraceous with obsolete annuli of a dark 

 l^rown.
