GLISCHROCENTRUS.—CENTRUCHOIDES. 161 
GLISCHROCENTRUS, gen. nov. 
Gen. Phaulocentro maxime affine, sed oculis minus prominentibus, haud subpetiolatis, pronoto simplici obtuse 
supra metopidium producto, areisque tegminum discoidalibus duabus, facile distinguendus. 
Very closely allied to Phaulocentrus, but distinguished by having the forehead more even, the frontal tubercles 
very small, the eyes less prominent, and the pronotum without the ordinary central carina, and obtusely 
produced above the metopidium; the teemina, moreover, have only two discoidal areas; the latter 
character, however, is somewhat difficult to distinguish in these genera. 
A single species from the State of Panama is referred to it. 
1. Glischrocentrus cucullatus, sp. n. (Tab. X. figg. 5, 5a.) 
Opacus, testaceus, unicolor, subtiliter flavo-pubescens; capite quali, subtilissime punctato; pronoto dense 
punctato, a latere viso sensim antice a basi elevato, perobtuse cucullatim producto, carina centrali utrinque 
leviter impresso, supra viso ad humeros latissimo, deinde versus apicem basinque sensim et equaliter 
angustato ; processu postico modico, fere recto, emarginatione utrinque angusta apice rotundato; scutello 
plano; tegminibus cum pronoto concoloribus; abdomine pedibusque testaceis, tibiis ad partem perobscure 
infuscatis, 
Testaceous, dull, finely pubescent; head even, very finely punctured; pronotum, if viewed from above, quadri- 
lateral, with the sides equal, broadest at the shoulders, produced behind into a straight process, on each 
side of which the base is narrowly and roundly emarginate; if viewed from the side gradually raised from 
the base to the front, where it is very obliquely produced above the metopidium ; scutellum level; tegmina 
concolorous with the pronotum ; abdomen and legs testaceous, the tibiz in parts very obscurely darker. 
Long. cum tegm. 5 millim.; lat. int. hum. 2 millim. . 
Hab. Panama, Volcan de Chiriqui 2500 feet (Champion). 
One female example. 
CENTRUCHOIDES, gen. nov. 
Oblongus, capite inter oculos lato, oculis fortiter prominentibus, ocellis inter se quam a basi horum minus 
remotis ; metopidio supra caput leviter plicato; pronoto humeris obtuse prominulis, cornibus supra hos 
magnis, latis, oblongis, truncatis, latere superiori seepe apicem versus exciso; basi pronoti utrinque ad 
basin processus postici profunde circulariter emarginata, hoc longo, angusto, subparallelo, apice acuto, fere 
ad apicem abdominis extenso; tegminibus totis opacis, corio areis apicalibus quinque, discoidalibus tribus, 
clavo venis duabus in disco distinctis; alis areis apicalibus quatuor, discoidali nullé; pedibus teretibus ; 
abdomine supra et subtus cereo. 
Oblong, with the head broad between the eyes, which are very strongly prominent and almost entirely 
exposed if viewed from above; ocelli nearer each other than to the eyes; pronotum with the shoulders 
obliquely prominent, above which are two very large and broad, though not long, horns, which are trun- 
cate at the apex and carinate above, and often notched on their upperside, thus presenting a short sharp 
point at about the middle—they are, however, somewhat variable in size, direction, and shape; base of 
the pronotum strongly excavated on each side of the posterior process, which is long, subparallel, and 
acute, and reaches almost to the apex of the abdomen; scutellum about as broad as long, strongly 
emarginate at the apex ; tegmina opaque, corium with five apical areas, which are more or less oblong 
and subequal, and three discoidal areas, radial vein straight and uninterrupted, ulnar vein bifurcate 
near the base and again at about the middle near the transverse vein of the third discoidal area; wings 
with four apical and no discoidal areas ; abdomen cereous. 
This genus in facies appears to be closely allied to Centruchus and Oxryrhachis, both 
of which are peculiar to the Old World. Apart from other differences, it may be
