80 HEMIPTERA-HOMOPTERA. 
Fam. CIXIIDA*. 
The Cixiide are here treated, for convenience, as a separate family, but there is no 
definite distinction between them and the Dictyopharine, of the family Fulgoride. 
The presence or absence of a frontal ocellus does not hold good, nor does the further 
character given for the Cixiide which do not possess a frontal. ocellus, viz. that “if 
the frontal ocellus is absent, the clypeus is not keeled.” In both groups species occur 
with a distinct cephalic process, although in this case the venation of the tegmina 
affords a good character for distinction. The Cixiide, together with the Dictyopharine, 
the Achilide, Derbide, Isside, and Delphacide, should be regarded as tribes or sub- 
families of the Fulgoride, under which Stal and others include as subfamilies the 
Flatide, Acanoniide, and Ricaniide. 
The following genera of Cixiide are represented in our collection :— 
I. Vertex produced into a long snout; apex of tegmina not reti- 
culate; frontal ocellus distinct . . . . . . . . . . . Ruampurxius, gen. nov. 
II. Vertex not produced into a snout. 
i, Frontal ocellus present, usually very distinct. 
1. Sides of frons produced at sides and auriculate, if viewed 
from above; tegmina not tectiform or adpressed to the 
sides. 
A. Frons and clypeus together forming an isosceles triangle 
with the vertex at base . . . » . « « « . . Borariocera, Klug. 
B. Frons narrowed towards base, widest towards apex . . BoTurioceRopEs, gen. nov. 
2. Sides of frons not produced or auriculate, except very rarely, 
in which case the tegmina are upright and adpressed to 
the sides. 
* Tegmina more or less evidently (though sometimes very 
slightly) dilated behind the apex of the clavus; mostly 
obscure, more or less opaque, dark species, with the 
tegmina adpressed . . . . . . . Meraprrxra, gen. nov. 
** Tegmina not dilated: behind the apex of ‘the clavus, not 
adpressed to the sides, almost always vitreous and 
transparent. 
A. Vertex extremely narrow, reduced to a mere slit between 
theeyes . . .. . soe ee ew .) .) 6<OcxreEvs, Stal. 
B. Vertex broader than long, or at most not much longer ~ 
than broad. . 
a. Scutellum with five keels . . . . . . . . . Ontarus, Stal. 
6. Scutellum with three keels. 
aa. Tegmina with the veins coarsely granulate. . . Crxius, Latr. 
6b. Tegmina with the veins not or scarcely visibly 
granulate . . . . . . . . . . . . . Hapraxtus, gen. nov.
