25. Orphulella robusta, sp. n. 



Bather robust, with the tegmina and wings only slightly surpassing ( tf ) or not quite reaching ( 2 ) the tip of 

 the abdomen. Basal joints of the antennae depressed, in the S considerably longer than, and in the 2 

 about as long as, the head and pronotum together. Head large, a little wider than the front edge 

 of the pronotum above, evenly expanding below and gently sulcate throughout ; fastigium of the vertex 

 rather prominent, the sides in the tf meeting in front in an acute angle, in the 2 in about a right angle, 

 shallowly sulcate and provided in the middle anteriorly with a well-defined carina; lateral foveoloe 

 obscure, triangular. Pronotum moderately long, the anterior lobe somewhat the longer, only the last 

 transverse sulcus at all profound; lateral carinse parallel on the anterior lobe, gently divergent on the 

 posterior lobe, hind edge subangulate. Tegmina irregularly reticulate, their costal edge somewhat dilated 

 near the base. Hind femora moderately robust^ surpassing the abdomen in both sexes. 



General colour above greenish or testaceous, varied with the usual dark line along the upper edge of the sides 

 of the pronotum. Anterior edge and disc of tegmina brownish or fuscous, and in some specimens showing 

 a central series of dusky dots, the dorsal edges green or greenish. Hind femora with their apices dusky ; 

 tibiae brownish-purple.

[PAEACHLOEBATA, gen. nov. 



Not unlike Orphulella and Amhlytropidia, but structurally quite different from either of them, though closest 

 to the former, as will be seen by the characters given in the analytical table for the separation of the 

 genera of this subfamily, as treated in the present work. 



Body compressed, rather smooth. Head of medium size, about as wide as the front edge of the pronotnm, the 

 occiput nearly straight and about on the same plane with the disc of the pronotum ; eyes not prominent, 

 pointed above, straight in front, rounded behind ; fastigium of the vertex convex (instead of grooved), 

 wider than long, the bounding walls rounded, low, meeting in front in more than a right angle ( 2 ) and 

 with a slight median carina at the apex (thus calling to mind the vertex of Amhlytropidia) ; lateral: 

 foveolae subobsolete, represented only by slight irregular depressions. Face, when viewed in profile, very 

 gently sinuate, owing to the prominence of the frontal costa between the antennae and a slight depression 

 of it at the ocellus, its sides gently divergent to just below the ocellus, where they approach and again 

 diverge to the clypeus ; plain above, but gently sulcate below the ocellus. Antennae filiform, apparently 

 shorter than the combined length of the head and pronotum (partially broken in the specimen at hand). 

 Pronotum with the sides nearly perpendicular, gently contracted in the middle, the median and lateral 

 carinse prominent, the latter broadly arcuate and approaching much more closely on the front margin of 

 the anterior lobe than on the hind edge of the posterior lobe ; the transverse sulci very dim, the last about 

 the middle ; front edge straight, the hind edge scarcely angulate ; sides about as deep as long, their upper 

 edge excavated, so as to leave a broad irregular depression next the lateral carinae on the anterior lobe, 

 the remaining portion, except near the middle, roughened. Tegmina about as long as the abdomen, with
