160 HEMIPTERA-HOMOPTERA. 
2. Phaulocentrus proximus, sp.n. (Tab. X. figg. 2, 2a.) 
P. pileato maxime affinis, sed tuberculis capitis minoribus, emarginationibus ad basin processus pronoti minus 
latis, angulis lateralibus magis productis, et preecipue scutello ad basin vix elevato, processuque pronoti 
haud arcuato, fere recto, longiori, distinguendus. 
Very closely allied to P. pileatus, and at first sight inseparable from it; the general colour, however, is more 
uniform, the tubercles at the base of the head are smaller, the formation of the disc of the pronotum is 
somewhat different, the space included by the carinzee being wider behind and more narrowed in front; 
the posterior pronotal process is longer and almost straight, and not arcuate above the scutellum as in 
that species, its extreme apex being dark, and the tegmina are obscurely lighter at the base. 
Long. cum tegmn. 7 millim.; lat. int. hum. 23 millim. 
Hab. GuateMAta, Cerro Zunil 4000 feet (Champion). 
One female example. There is also in our collection a specimen with the abdomen 
wanting, which is closely related to this species; it is, however, smaller and much 
darker and more variegated, and has the raised disc of the pronotum somewhat 
differently formed. When more specimens are obtained, it may possibly be found to be 
the male of one of the species here described, but I believe it will prove to be distinct. 
8. Phaulocentrus sordidus, sp.n. (Tab. X. figg. 8, 3a.) 
P. proximo affinis, sed colore magis brunneo, tuberculis capitis vix distinctis, pronoto supra excavato et 
utrinque in lobum perobtusum elevato, margine anteriore excavationis recta, marginibus lateralibus 
leviter postice convergentibus, carina centrali in metopidio continuato, processu postico fere recto, apice 
fusco, emarginatione ad basin utrinque lata rectilineari ; tegminibus ad basin testaceo fuscoque variegatis, 
pubescentibus, venis rufo-testaceis; corpore subtus pedibusque testaceis, his obscure variegatis. 
Allied to P. proximus, but rather narrower and more darkly coloured, with the tubercles at the base of the 
head very small, and the disc of the pronotum differently sculptured, the lateral carine being raised on 
each side into a blunt lobe, and being slightly convergent behind ; the posterior process is almost straight 
and the emarginations on each side of it are broader and squarer than in P. provimus; the tegmina have 
a testaceous patch at the base, bordered broadly on each side with fuscous, the colour being more or less 
obscure, and the apex of the clavus is testaceous, followed by a small fuscous patch on the corium, the 
veins rufo-testaceous; legs and abdomen testaceous, the former very obscurely variegated. 
Long. cum tegm. 7 millim. ; lat. int. hum. 24 millim. 
Hab. Mexico, Soledad in Guerrero 5500 feet (H. H. Smith). 
In the single example of this species received, a female, the tegmina have six apical 
areas, but the first external area is small and perhaps abnormal, the regular number 
for the genus being evidently five. 
4. Phaulocentrus cornutus, sp.n. (Tab. X. figg. 4, 4a.) 
P. proximo quoad staturam et colorem maxime affinis, sed pronoto antice duobus magnis latis cornibus 
instructis, auriculatis, ad apicem late rotundatis, introrsum carinatis, processu postico testaceo, apice 
nigro, leviter recurvato. 
Of about the same size and colour as P. proximus, but easily distinguished by the pronotum being furnished 
with two large porrect auriculate horns, which are broadly rounded at the apex, and are carinate on their 
inner side; the pronotal process is testaceous, black at the apex, and if viewed from the side is curved, 
and widened at the apex. 
Long. 72, cum cornibus 9 millim.; lat. int. hum, 24 millim. 
Hab. Mexico (Mus. Oxon.).
