108 CORYLOPHIDZ. 
1. Conodes conicus, sp. n. (Tab. III. figg. 17, 17a.) 
Conicus, sat depressus, nitidulus, testaceus, pilis brevibus aureis vestitus; capite sat parvo, antice attenuato ; 
oculis nigris, sat magnis, haud prominentibus ; pronoto brevi transverso, ad basin latissimo, leviter alutaceo, 
lateribus circulariter rotundatis et marginatis, margine basali fere recta angulis obtusis ; elytris longis, 
quam caput atque pronotum haud latioribus, sed plus quam duplo longioribus, ad humeros latissimis, 
postice attenuatis, profunde et rugose punctatis, linea suturali profunda impressis, lateribus fere rectis, 
late marginatis, apicibus valde rotundatis; pygidio exserto ; pedibus atque antennis robustis, lete flavis, 
tibiis dilatatis. Long. corp. 38 lin.=1 millim. 
Head moderate, rather acuminate in front, finely punctured or alutaceous ; eyes rather large, not prominent ; 
antenne robust, bright yellow. Thorax short, transverse, widest at the base, finely alutaceous; sides 
margined and circularly rounded; basal margin nearly straight, with the angles obtuse. Scutellum large, 
rounded, and punctured. Elytra long, not broader than but more than twice as long as the head and thorax, 
widest at the shoulders, attenuated posteriorly, deeply and rather rugosely punctured, with a deeply im- 
pressed line on each side of the suture ; sides nearly straight and rather broadly margined ; each apex much 
rounded. Abdomen with the pygidium exposed. Legs robust, bright yellow, the tibiz more or less 
dilated. Underparts testaceous. 
Hab. Guatemata, Capetillo (Champion). 
This very distinct and pretty species, of which only two specimens were found, is 
probably, in life, of a bright golden-yellow. 
SACIUM. 
Sacium, Leconte, Proc. Acad. Phil. vi. p. 144 (1852). 
Body elongate, with the underside very convex. Head wholly concealed by the thorax. Thoraw with the 
front margin entire, the hinder angles not produced. Scutellwm small, generally rounded. Llytra long, 
with the apices separately rounded. Abdomen with the pygidium exposed. Antenne rather long, 
11-jointed—1 long, incrassate, and much recurved, 2 much shorter than 1, incrassate, 3-6 short and 
slender, 7 often much longer than 8, 8 small, 9-11 much incrassated, forming a subfoliate club. 
Palpt: maxillary large, 4-jointed—1 small and slender, 2 very large, pyriform, abruptly truncate, 
3 subquadrate, shorter, but scarcely narrower than 2, 4 long, robust, obtusely conical; labial large 
and circularly rounded, 3-jointed—l very minute, 2 cyathiform, immensely dilated, 3 very large, 
subquadrate, with anterior margin denticulate. Mentwm oblong, with the anterior margin deeply 
excavated. Labium elongate, oblong, slightly constricted near the middle, strengthened at the sides 
with strong coste, and armed at the anterior extremity with two long, erect, very sharp paraglossal 
processes on each side. Lingua large and broad, emarginate at the apex. Labrwm small, semioval, 
emarginate in front. Maaille unilobed, the lobe very robust, very strongly hooked at the apex, and armed 
with five very long and very sharp teeth. Mandibles not much curved, armed with five very sharp and 
strong teeth. Prosternum moderate, elevated between the coxee, produced and much dilated beyond them ; 
episterna minute ; epimera large, rather broadly enclosing the coxal cavities; coxal cavities large, rounded. 
Mesosternum short ; episterna rather small; epimera large and broad, not extending to the coxal cavities ; 
coxal cavities rounded, moderately distant. Metasternum large, not extending to the sides of the body, the 
posterior margin between the coxe straight; epzsterna very large and broad, longer than the metasternum ; 
epimera long, concealed by the elytra. Venter composed of six segments—l very large, as long as the 
metasternum, 2-6 equal to each other in length, the apical segment simple. Legs long: anterior with the 
trochanters long, not triangular; femora rather short, simple; tibie: moderate, widest at the apex; tarsi 
long, 4-jointed—1 and 2 slightly bifid, 2 smaller than 1, 3 very minute, 4 very long; claws robust, 
unidentate below ; intermediate similar to, but much longer than, the anterior; posterior similar to, but 
longer than, the intermediate. 
A widely distributed genus containing a large number of described species.
