FAM. MEMBRACID/E 289 



in the middle in a deep pit belovv the overhangiiig margin of the pronotum ; ejes small and giobular 

 (bright red in the type species); ocelli large, conspicuous (brilliant red in the type), twice as far removed 

 from the eyes as from each other and situated low on the face, about on a hne drawn through lower 

 margins of eyes; inferior margins of gense broadly rounded ; clypeus three times as long as broad, extend- 

 ing for its entire length below the inferior margins of the gense, tip pointed and pubescent. Pronotum 

 convex, gibbous, entirely unarmed, elevated into a crest with a high thin keel on the median dorsal 

 hne: metopidium sloping, broader than high, extended into a flange over the head; median carina 

 strongly percurrent, raised in a flattened plate on the pronotum; humeral angles very large, broad, 

 triangular and blunt; no suprahumeral horns ; no posterior process ; scutehum entirely exposed, sub- 

 triangular, swollen at the base, about as broad as long, tip acute. Tegmina long, narrow, opaque, 

 the entire surface reticulated by heavy raised veins which form a very large nuuiber of small, irregular 

 cells; basal area broadly coriaceous and punctate ; tip rounded ; no apical limbus. Legs long, slender 

 and simple; hind tarsi longest. Dorsal sclerite of terminal segment of abdomen extended into a long 

 tube-like rod, cyHndrical and pilose, as long or longer than the abdomen itself. 



Type hardwicki Gvay. 



Geographical distpibution : This is an Indian genus wilh the type species (which is the 

 only species known) apparently quite common and having a wide distribution over that region.

Characters : The insects of this genus, which are apparently very cercopid-hke in apjiearance, 

 are unknown to us but they have been recognized and described often enough to indicate that the\- 

 possess distinctive characters sufficient to justify the jistint^ of the genus as valid. The genus is certainly 

 quite different from either of tlie other genera of tlie tribe. (iermar's excellent original description of the 

 genus as well as the descriptions given by Stal for the synonymous genera make it possible to summarize 

 the more important generic characters as foUows : Head subquadrate, wider than high, dellexed ; e^es 

 large; ocelH prominent, equidistant from each other and from the e^es; inferior margins of gente flattened 

 and rounded; clypeus extencHng below inferior margins of gense. Pronotum convex and entirely 

 unarmed; no suprahumeral horns; no postei ior process ; scutellum entirelj' exposed, short, subtriangular, 

 base transversely impresseil. Tegmina coriaceous with reticulated venation. Legs somewhat flattened ; 

 hind tarsi longest.
