same plane as the vertex. Ocelli immediately basal of this, much 

 nearer the eyes than to one another. Frons excavate as in the 

 other genera, but the head not at all foliaceous. Pronotum 

 roundly declivous, anterior margin rounded in front, posterior 

 margin roundly emarginate medianly. Tegminal venation ob- 

 scure, subreticulate; with an appendix.

Bluish black; vertex, pronotum and scutellum polished; be- 

 neath dull black. The whole surface more or less covered with 

 red powder, doubtless similar to the white flocculence of the 

 Fulgoroidea. The dorsal part of the irons, eyes, and small 

 false-ocellar spots on vertex, etc., are certainly red, and possi- 

 bly other parts, but it is impracticable (in the unique type) to 

 determine what is colour, what powder.

Subfamily Agalliinae.

Distinguished from Idioceriis by the quite different ventaion, 

 especially the constitution of the discoidal cells and the pres- 

 ence of 5 apicals; there are also transverse veinlets towards the 

 apex of the subcostal (marginal) cell, and there are 2 transverse 

 veins standing on the cuibital. The antennal ridges also extend 

 only a'bout one-half of the distance from frons to eye, and are 

 shallow. 



Very little of the vertex can be seen dorsally, 'and the eyes 

 are prominent, not forming part of the curve oi the head; the 

 apical margin of the vertex is ventral and is emarginate round- 

 ly, to admit the base of the diamond-shaped frons; ocelli placed 

 a little laterally, right against the frons, close to the apical mar- 

 gin of the vertex. Frons with a very slight, ovate swelling in 

 the center, from base to apex. Clypeus o'blong, longer than 

 wide, lorae rhomboid, about as wide or a little wider, each, than 

 clypeus, slightly rounded posteriorly exterolaterally. Rostrum 

 about twice as long as clypeus. Antennae socketted on a level 

 with the posterior margin of the eyes, simple in both sexes. 

 Vertex and pronotum^ transversely, finely, but a little irregular- 

 ly, aciculate-punctate. Head and eyes distinctly wider than
