body, the costal margin distinctly expanded on the basal fifth or 

 less, increasing slightly in breadth apically, the tip narrowing and 

 rounded; wings almost half as long again as the tegmina, reaching 

 as far backward as the tips of the femora. Legs exceedingly long 

 and slender, the hind femora very slightly thickened; all the cox ae 

 with an inferior, the anterior coxae also with a superior spine ; under 

 surface of all the femora with a row of exceedingly delicate distant 

 spines ; fore femora nearly twice as long as head and pronotum to- 

 gether; geniculations of hind pair apically denticulate on either 

 side; all the tibiae sulcate externally, the foramina of the front pair 

 elliptical, about three times as long as broad ; hind tibiae equal 

 throughout, much longer than the femora, furnished beneath with, 

 two apical spines; second joint of all the tarsi apically bidenticulate 

 above. Abdomen compressed, with a median ridge on the basal 

 half; subgenital plate of male apically bidentate, destitute of styles ; 

 ovipositor of female very short and broad, upturned, strongly com- 

 pressed, very bluntly pointed. 



The excessive length of the legs gives this genus a very peculiar 

 appearance. It is allied to Acrometopa Fieb. 



Aegipan grallator. Green. A faint pinkish stripe behind the 

 top of the eye, crossed longitudinally by a slightly curving, tapering, 

 white line. Anterior lobe of pronotum with an oblique white line on 

 either side marking a ridge, approximating posteriorly, often bor- 

 dered above with pink; posterior border of pronotum edged rather 

 broadly on the ' deflected lobes, narrowly above, with white, every- 

 where delicately margined with pink. Limitation of the anal and 

 median field of tegmina marked with dull pink ; the hind femora 

 often, and occasionally the other femora tinged, excepting at the ex- 

 tremities, with pink. Abdomen with a faint whitish lateral line, 

 bordered distinctly below, faintly and narrowly above, with pink. 

 The tympanum of the male tegmina as long as the pronotum. Inner 

 margins of the apical denticles of the subgenital plate meeting at the 

 middle of its apex; ovipositor of female green, pinkish apically at 

 the edges, considerably longer than broad, externally scabrous with 

 raised points directed apically, the edges serrate, with small but stout 

 serrations. Length of body, cf , 16.5 mm., ?, 18.5 mm. ; of antennae, 

 cf, 56 mm., ?, 60 mm.; of tegmina, cf, 23 mm., ?, 26.25 mm.; of 

 wings, cf, 32.75 mm., ?, 34.5 mm.; of hind tibiae, cf, 37 mm., ?, 39 

 mm. ; of ovipositor, ?, 4.2 mm.
