similarly black -speckled cephalic femora, which, however, bear 

 four striking, opaque, buffy patches; tegmina which have the median 

 vein with two weak branches beyond the forked first branch, 27 

 and male subgenital plate which is produced distad in two tri- 

 angular and not lobate projections, each showing on its inner 

 margin a minute rectangular offset, rather than an acuminate tooth. 

 Type: tf ; Singapore, British Straits Settlements. (From C. F. 

 Baker.) [Hebard Collection, Type no. 797.] 



Vertex narrowly V-shaped and sulcate to near apex. Maxillary 

 palpi exceedingly elongate and slender, fourth joint half as long- 

 as third and one-third as long as fifth. Pronotum with surface 

 smooth, disk defined from lateral lobes by the broadly rounded 

 lateral margins, lateral lobes decidedly deeper than wide, with 

 humeral sinus deep. Tegmina and wings fully developed, the 

 delicate but close veinulation of the former giving them somewhat 

 the appearance of ground-glass; tegmina with ulnar vein reaching 

 sutural margin slightly beyond end of its proximal two-thirds, 

 median vein branching distinctly before median point, two strongly 

 oblique and irregular branches of the median vein distad. Supra- 

 anal plate strongly deflexed, short, slightly broader than long, 

 triangular, with lateral margins broadly convex. Anal tergite 

 truncate distad. Cercus elongate, slender, weakly and evenly 

 curved inward, tapering gradually to its acute apex. Subgenital 

 plate narrowing proximad, distal portion V-emarginate, the lateral 

 portions thus formed narrowly triangular with apices rounded, their 

 internal margins each with a minute rectangular offset mesad. 

 Genicular lobes of femora unarmed, except those of caudal femora 

 which are unispinose. Ventral femoral margins armed with minute 

 spines as follows. Cephalic internal 8, cephalic external 0, median 

 internal 0, median external 8 and 9, caudal internal 6 and 7, caudal 

 external 5 and 7. 



Tegmina translucent light grape green, body and limbs in life 

 apparently of this color. Maxillary palpi immaculate. Pronotum, 

 abdomen, median and caudal femora minutely and thickly dotted 

 with hydrangea red. Cephalic femora very thickly dotted with 

 black, with five opaque buffy areas on dorsal surface, spines of 

 these members black. Cephalic tibiae with a few black dots prox- 

 imad, particularly dorsad on the auditory foramina. Tegmina, 

 in areolae on each side of the ulnar vein with a few of the minute 

 intervals between the veinlets mesad black, six or seven cross- 

 veins near median vein gathering knots of veinlets near their bases, 

 which are buffy; stridulating field with intervals between veinlets 

 embrowned latero-proximad and mesad, sutural margin beyond 

 very narrowly darkened, with veins brown and intervals between 

 veinlets blackish, to apex.
