Pale greenish testaceous; teg'niina hyaline, veins more or 

 less greenish testaceous. 



Length: lo-ii mill. 



Hab: Viti Isls. (iii), arboreal. 



Nymphs: The vertex is angular anteriorly, and angulately 

 emarginate posteriorly. The pronotum is acute-angled an- 

 teriorly, reac'hing almost to apical margin of eyes, posteriorly 

 emarginate. Whole insect medianly carinate from apex of ver- 

 tex to apex of abdomen. Ventrally, the frons is nearly twice 

 as long as wide, carinate laterally and medianly, the latter keel 

 not reaching anterior margin, and at visible base of Irons send- 

 ing out forks at ri'gfht angles which curve around and meet 

 again at apex of frons. The transverse space between this 

 basal keel and the anterior margin of the vertex, is dorsal and 

 is rounded anteriorly (as seen dorsally). It is crowded with 

 sensory organs, and lightly keeled medianly. The space be- 

 tween lateral and sublateral keels on frons is also provided 

 (much less thickly) with sensory organs. Eyes prominent. 

 Nota and teg-minal pads with a few sensorv organs. 



Pale greenish testaceous, a crimson stripe (or keel) from 

 apex of vertex to apex of abdomen, broadening sufifusedly as

 each side and a median, also a curved submedian keel on each 

 side, becoming- obsolete on the basal ihalf. Pronotum tricarin- 

 ate, angularly rounded anteriorly, deeply rectangularlv emar- 

 'ginate posteriorly. Scutellum short, tricarinate, the lateral 

 keels rounded, meeting anteriorly. Costa arched, costal cell
