AUSTRALIAN LEAF-HOPPERS.

The pronotuin is transversely striated, produced anteriorly and narrow laterally. 
The propleurae separate the eyes from the bases of the tegmina. Posteriorly the 
pronotum is at a higher level than anteriorly. The scutellum is flat and transversely 
striated. The tegmina are brown, narrow apically and the veins are much branched 
apically. The hind tibiae have three rows of small spines and a row of six flattened 
spurs with apical spines, diminishing in size from the apex to the base. The first tarsal 
segment of the hind tibia is more than twice the length of either of the other tarsal 
segments.

The crown is only slightly wider medianly than laterally. The tegmina are 
largely transparent, brown or black basally and medianly, and have many less ante- 
apical cells than with the $. The body is usually black whilst that of the female may 
be light or dark brown. 
SMICROCOTIS Kirk. 
H.S.P.A. Exp. Sta. Bull. 1 (9) ; 370, 1906. 
The following five species belong to this genus ; obscura Kirk. (1906) (Type) 
sidnica Kirk. (1907) ; pallescens Dist., infuscata Dist. , projecta Dist. (1907) ; claudenda 
Walk. (1858). It is probable that S. infuscata is synonymous with the genotype. 
Two new species are described below, a re-description is given of the genus, and 
figures of the genotype (figs. 7-9). 
$, The head ventrally is longer than wide and is recurved apically. The 
maxillary plates extend alongside and beyond the clypeus as narrow borders. The 
labium extends to the middle of the hind coxae and the antennal ledges which are 
indistinct reach only as far as the frontal sutures. The hind margin of the frons (or 
post-clypeus) is distinct and lies well forward of the apex of the head ; posterior to 
this the margin of the vertex (here doubtless the true frons), is raised into a median 
ridge. The ocelli which are marginal are directed ventrally. The crown of the head 
is produced anteriorly, the apical margin is straight or irregular and in some species 
the apex of the head is tilted dorsally. The eyes are not prominent. 
The pronotum may be flat or raised, either anteriorly or posteriorly, and is 
transversely striated posteriorly. The tegmina which are an opaque brown are 
rounded apically and the veins are raised in relief. The hind tibiae in addition to three 
rows of small spines have a row of four flattened spurs bearing apical spines, these 
diminish in size from the apex to the base.
