RHAMPHIXIUS, gen. nov. 
Capite longo, vertice perangusto in rostrum plus minusve elongatum prolongato, oculis longis, subtus emar- 
ginatis, ocello utrinque prope oculos tertioque frontali conspicuo, fronte perangusta; pronoto perbrevi, 
ad latera paullo ampliato; scutello magno, distincte tricarinato; tegminibus sat amplis, vena radiali et 
vend interiori ulnari pone medium eequidistanter furcatis, areis tribus subapicalibus obliquis; tibiis 
simplicibus. 
Head long, with the vertex extremely narrow and produced into a longer or shorter process, which is flattened 
at the sides, truncate at the apex, and sulcate above and beneath, the underside forming the continuation 
of the very narrow frons, the latter slightly widened in the centre and having the frontal ocellus very 
distinct ; eyes elongate; pronotum widened at the sides; scutellum long, distinctly tricarinate ; tegmina 
widened behind, with the radial and interior ulnar veins rather widely forked at about an equal distance 
from the apex, and with three oblique subapical areas; tibia simple. 
The position of this genus is somewhat hard to determine; at first sight it appears 
to be near Dictyophara, but the distinct frontal ocellus places it not far from Crrzus ; 
the venation of the apical portion of the tegmina is somewhat like that of Lycoderes 
among the Membracide. 
1. Rhamphixius championi, sp. n. (Tab. IX. figg. 10, 10a, 6.) 
Subpellucidus, testaceus, oculis fronteque nigris, processu frontali ad latera fusco-testaceo; scutello levi, 
carinis tribus distinctis; tegminibus sutura late, maculis marginalibus et apicibus infuscatis, venis 
distincte granulatis ; abdomine subtus pedibusque testaceis. 
Testaceous, with the sides of the frontal process darker, and with the eyes and frons black ; scutellum smooth, 
with the three carine very distinct ; tegmina subpellucid, with the suture and apex more or less broadly 
infuscate, and with a fuscous marginal spot at the sides before the apex, the veins very distinctly 
granulate; abdomen and legs testaceous. 
Long. cum tegm. (sed sine processu frontali) 6 millim.; cum processu frontali 72-8 millim,; lat, ad hum. 
2millim. (2.)
