164 HEMIPTERA-HOMOPTERA. 
1. Stylocentrus championi, sp. n. (Tab. X. figg. 8, 84.) 
Niger, capite, metopidio et lateribus pectoris squamis albis maculato, et lineé utrinque pronoti albo-squamosé ; 
oculis valde prominulis ; pronoto haud nitido, remotius punctato, lined centrali elevata, processu trispinoso 
gracillimo, spina intermedia fere ad apicem tegminum producto; scutello brevi, apice acuto; tegminibus 
pellucidis venis nigris, quibusdam latis; abdomine rufo, apice fusco; pedibus nigris, tarsis tibiarumque 
apicibus flavis. . 
Black, dull, with the head and front parts of the pronotum furnished with more or less distinct patches of 
white scales, which are present in two broad lines on each side of the pronotum, these lines almost meeting 
beneath the base of the trispinal process, where they are separated by a narrow line; the sides of the 
chest also, which is dark, are furnished with large patches of similar white scales; the trispinose process 
is very long and slender; the pronotum is distinctly but somewhat remotely punctured, as is also the 
scutellum, which is very short and terminates in a short sharp point; the tegmina are transparent, with 
dark veins, some of which are broad and thick; the clavus and external part of the corium are rather 
strongly punctured, especially towards the base, and the claval margin is somewhat thickened, with the 
dark colour tapering to the apex, so that the scutellum appears to be elongate until the tegmina are 
divided ; abdomen red, with the apex fuscous; legs black, with the tarsi and the apex of the tibie yellow. 
Long. 6 millim.; lat. inter spinas exteriores processus pronoti 4 millim.

LYCODERES. 
Lycoderes, Germar, Rev. Ent. Silb. iii. p. 259 (1835); Stal, Kongl. Vet.-Ak. Handl. Band viii. 
1, p. 52 (1869). | 
The two species below described evidently belong to Lycoderes, Germ., but they 
differ from the normal members of the genus in having the scutellum concealed. Some 
of the species, of which there are a considerable number (mostly from Brazil), are 
among the most extraordinary of the Membracide. The genus Stegaspis is closely 
allied to Lycoderes, but the pronotum is more foliaceous in front and is never lobed at 
the apex. 
Stal (/. c. p. 53) has divided Lycoderes into several subgenera on the formation of 
the pronotum and the areas of the tegmina. 
1, Lycoderes phasianus, sp.n. (Tab. X. figg. 9, 9a.) 
Elongatus, brunneo-ferrugineus, unicolor, supra visus angustatus maxime compressus, a latere visus ampliatus, 
ab apice tegminum usque ad basin cornus pronoti leviter et equaliter rotundato, hoc porrecto, haud 
longo, parallelo, apice bilobato ; pronoto acute carinato, fortiter et rugose, sed varie, punctato, apice postico 
obtuso apicem clavi vix superante ; scutello obtecto; tegminibus cum pronoto concoloribus, opacis, ad 
basin fortiter punctatis ; abdomine pedibusque testaceis. 
Much compressed, of a unicolorous ferruginous-brown colour, very narrow if viewed from above, if viewed 
from the side broad and evenly rounded from the apex of the tegmina to the base of the pronotal horn ; 
the latter is comparatively short, porrect and elevated, rugose at the sides, and bilobed at the apex; the 
pronotum is strongly punctured, but more closely at the shoulders than on the sides, on which are present 
several rugose raised lines ; the apex just reaches the apex of the clavus ; scutellum concealed ; tegmina 
dark, opaque, punctured strongly at the base; abdomen and legs clear yellow-testaceous. 
Long. cum tegm. 9 millim.; lat. int. hum. 17-2 millim.
