10. rewana, sp. nov. 



Yellowish-brown, paler beneath, pronotuni somewhat sordid, 

 abdomen blackish. Tegmina smoky hyaline ; clavus, sntural cell 

 of corium and svibcostal cell, pale yellow smoky in parts ; veins 

 pale yellow ; a dark smoky spot at apex of tegmen. Wings smoky 

 hyaline, veins smoky. Vertex somewhat convex, roundly pro- 

 minent in front of eyes, but not so long as wide. Four apical 

 cells to the tegmen, the first very small. 



Length 2^j-2y2 mill. 



Hab. Viti Levu, Rewa (Mar. & Dec. M.). 



The yellow is apt to fade and become obscure. 



Nymph: The ultimate stage (as far as can be judged from 

 the empty skin) is brcwnish-yellow. Head produced in front 

 of eyes at least as far as the length of the rather long eyes be- 

 yond them. Antennal peduncle elognate and conspicuous, flagel- 

 lum much longer than the body. There are a large number of 

 erect capitate hairs disposed as follows : 6 on the lateral and an- 

 terior margin of the vertex 4 on the pronotum, 8 submedian and 

 6 lateral on the abdoiuinal tergites, also a number on tlie meso 

 and metanotum, tegminal pads and legs. 



Dialecticopteryx, gen. nov. 



An aberrant genus, distinguished by the peculiar venation of 

 tegmina and wings. 



Vertex transverse, declivous, anteriorly rounded, not {cy 

 scarcely) prominent in front of eyes, longitudinally sulculate, 

 posteriorly marginate and raised from the pronotum. Pronotum. 

 tiansverse, little longer than the vertex, lateral margins short, 

 carinate. Scutellum longer than wide, abqut as long as the pro- 

 notum. Tegmina (PL i, fig. 7) sparsely punctured, venation 

 obscure ; the radial and median are united at the base, fork soon 

 after, but keep very close together till a little basal of the apical 

 calls when they reunite; cubital obsolete basally, only appearing 

 a little basal of the apical cells. The radiomedial reforks apical 

 of the subapical line, thus forming a triangular cell ; there are 2 

 quadrilinear cells interior of this (perhaps more if the apical 

 veins fork). No veins in the clavus and no appendix. The ex- 

 treme apex of the wing is unfortunately broken but enough re- 

 mains to show its peculiar character (see PI. i fig. 6). This 

 genus shows some relationship to Nesosteles, etc.
