length of the fourth and fifth respectively; next three decreasing in 

 about the same ratio; terminal joint one-half longer than the penulti- 

 mate. Prothorax much narrowed anteriorly and strongly elevated 

 posteriorly, but without any transverse depressions. Mesonotum 

 somewhat shorter than the pronotum, with strong, moderately con- 

 vergent parapsidal furrows; its surface indistinctly punctate. Scutel- 

 lum as broad as long, with a shallow transverse depression across its 

 base. Metanotum gradually declivous and tapering apically, with 

 reticulations and some carina 1 , the exact position of which cannot be 

 made out in the type specimen. Abdomen as long as the head and 

 thorax together, lanceolate, acute apically. Wings fully developed, 

 appearing hyaline; stigma very narrowly lanceolate. Veins piceous, 

 only the radial, basal, transverse, median and basal section of the sub- 

 median vein thickly chitinized, the first basal and first cubital cell 

 defined by nearly hvaline veins. Radial cell almost closed bv the 

 heavy part of the radius, and completely by its thinner, weakly chitin- 

 ized tip. First discoidal cell above with a petiole fully one-third as 

 long as the entire basal vein; first cubital cell receiving the recurrent 

 nervure at its apical third; median and submedian cells of equal 

 length. Legs very long; anterior coxa? and trochanters extremely 

 elongated, the coxa? nearly as long as the femora; the trochanters 

 equally long and strongly arcuate. Femora and tibiae of equal length, 

 the former strongly obclavate and the latter slender, straight. First 

 tarsal joint four times as long as the short second; third much swollen; 

 fourth very long; two-thirds as long as the tibia; fifth very short, 

 quadrate; forceps denticulate on both arms, the inner one reaching 

 the base of the second tarsal joint, at the tip with a large tuft of den- 

 ticles. Middle and posterior legs elongate and slender, but otherwise 

 of the usual form. 



Described from a female XXB1547. 



This species will be easily recognized by its extremely elongate and 

 slender antennae.

 brownish legs. Head transverse, about twice as broad as thick 

 antero-posteriorly, the lateral ocelli as far from the median one as 

 from the eye-margin. Surface of head smooth and shining above,
