18 RHYNCHOPHORA. 
3. Stereobates chiriquensis, sp.n. (Tab. I. fig. 15, front tibia and tarsus.) 
Rufus, opacus, breviter parceque hispidus; rostro ante antennas crebre punctulato; vertice profunde emar- 
ginato ; pedibus posterioribus robustis, minus elongatis. 
Long. 7 millim. 
Hab. Panama, Bugaba (Champion). 
Very closely allied to the other two species of the genus, but doubtless quite 
distinct. The depression on the vertex indistinct, quite dull. Eyes more convex. 
Thorax with coarse obsolete sculpture on the lateral parts. Carine of elytra feeble, but 
with fine erect distant sete, particularly well developed on the humeral carina. Legs 
with the tibie largely compressed-dilated, and armed with numerous very short stiff sete 
Metasternum and abdomen with very short, but conspicuous, depressed flavescent setae 
One specimen. 
HOMCEOLIZUS, gen. nov. 
Corpus gracile, setis erectis armatum. Antenne elongate ; clava valde elongata, triarticulata. Pedes elongati, 
graciles ; tibiis anterioribus intus excisis; tarsis omnibus gracilibus, articulo basali posteriorum maxime 
elongato. 
The remarkable species for which I have established this genus should be placed 
near Stereodermus and Cerobates, though in its elongate slender antenne it resembles 
Tonthocerus, having, however, joints 9-11 abruptly longer than those preceding it. The 
elongate antenne and legs, the slender tibiz, and the extremely long basal joint of the 
tarsi distinguish the genus from Stereodates, next which it should be placed. 
The antenne are inserted in the middle of the rostrum, which is about as long as the 
thorax; the latter is convex, with the base depressed, the middle sulcate, and feebly 
bicarinate. The breast and the basal ventral segments are elongate and not sulcate. 
The legs are unusually elongate and slender, the hind pair being remarkably so. The 
hind coxe are less widely separated than they are in Stereodermus, but not so approxi- 
mate as they are in Trachelizus. 
1. Homeolizus salvini, sp.n. (Tab. I. fig. 16.) 
Gracilis, setis erectis undique armatus, opacus, fusco-niger ; elytris fulvo-variegatis ; antennis rufo-obscuris ; 
pedibus variegatis. 
Long. 6-10 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne elongate; club long, its joints scarcely broader than those preceding, each 
of them several times longer than broad, terminal joint very long ; the erect sete very 
conspicuous. Rostrum moderately long, shining in front, quite opaque behind, and 
only obsoletely sculptured, convex between the eyes, which are moderately large. 
Vertex not impressed, and only feebly emarginate behind. ‘Thorax elongate, dull, not
