96 HEMIPTERA-HOMOPTERA. 
Besides the above species, there are three or four obscure insects in our collection 
which belong to this genus, but it is better not to describe them. There is also a 
single example of a species apparently allied to O. insignior, in which there is no frontal 
ocellus, and the division between the clypeus and frons is well-marked. 
CIXIUS.

The genus Cixius proper is distinguished by having the base of the vertex roundly 
emarginate, the pronotum tricarinate, and the granulations of the tegmina strong and 
distinct, and more or less setigerous. It is apparently very scantily represented in 
Central America, its place being taken by Gecleus and Oliarus. A distinct frontal 
ocellus is usually, but not always, present. 
1. Cixius montanus, sp.n. (Tab. X. figg. 25, 25 a.) 
Capite brevi, vertice transverso, excavato ; fronte rufo-brunnea, ocello frontali interdum distincto, interdum 
pene deficiente; pronoto perbrevi; scutello brunneo, ad latera dilutiori, sat levi, distincte tricarinato ; 
tegminibus pellucidis, vitta communi laté ad medium, maculisque quibusdam basim versus, fuscis, venis 
distincte fusco-granulatis; abdomine supra nigrescenti; pedibus testaceis. 
Head short, vertex transverse, excavate; forehead rufo-testaceous, with the central keel and margins ‘lighter ; 
frontal ocellus. sometimes distinct, sometimes very small or rudimentary ; pronotum very short; scutellum 
dark, lighter at the sides, with three distinct carine; tegmina pellucid, with a broad transverse band 
and some variable spots towards the apex fuscous, the band occasionally broken, the veins with strong 
dark granulations, the transverse ones towards the apex strongly but very narrowly marked with fuscous ; 
abdomen dark above, lighter beneath; legs testaceous. 
Long. cum tegm. 7 millim.; lat. ad hum. 23 millim. (Q.) 
Hab. Mexico, Omilteme in Guerrero 8000 feet (ZZ. H. Smith). 
Several specimens, all females. This insect superficially resembles the European 
C. nervosus and its allies. 
2. Cixius comptus, sp.n. (Tab. X. figg. 25, 26a.) 
Sat parvus, vertice brevi, excavato, carinato, antice subrotundato, testaceo, fronte clypeoque testaceis; ocello 
frontali indistincto; pronoto brevi, testaceo; scutello castaneo, distincte tricarinato; tegminibus pone 
humeros dilatatis, deinde subparallelis, pellucidis, parte basali ad suturam opaca, testacea, et vittis duabus 
irregularibus ad et pone medium brunneo castaneis, apicibus fusco-notatis; venis distinctis granulatis; 
abdomine plus minusve piceo; pedibus dilute testaceis. 
Rather a small species, with the vertex, frons, and clypeus testaceous, the former excavate and carinate and 
bluntly rounded in front; frontal ocellus small, but distinctly visible under a high magnifying-power ; 
scutellum castaneous or pitchy, with three distinct carine; tegmina dilated behind the shoulders, and 
from thence subparallel, transparent, with the parts near the suture in front opaque testaceous, bounded 
with darker colour, the shoulders with a dark patch, and at and behind the middle are two irregular
