EULYTOCERUS. 161 
EULYTOCERUS, gen. nov. 
Caput rostratum; oculi oblongi, integri; antennarum funiculus 5-articulatus, articulis latitudine paullo 
crescentibus, claya oblonga, subreniformis, articulis tribus liberis composita, 1° subtriangulari angulo 
apicali inferiore producto, 2°-3° transversis subtus productis. Coxe antice anguste separate; tibie 
superne rotundate, serrate ; tarsorum articulus 3 simplex. 
Head rostrate; eyes oblong, entire; antenne inserted before the lower angle of the eye at the sides of rostrum, 
but above the mandibles, in a pit separated by a plica from the anterior surface ; scape strongly clubbed, 
the funiculus short, 5-jointed, its 1st joint globose, the remaining joints transverse, increasing in width ; 
club oblong, subreniform, pubescent, three-jointed, the joints loosely articulate, the 1st triangular, about 
as long as broad, with the apical border oblique and the lower angle produced, the 2nd and 38rd _ joints 
transverse, oblique. Prothoracic pleura strongly inflexed, but not separated from the dorsum by a 
lateral border. Elytra separately rounded and overlapping the prothorax at the base. Anterior coxe 
separated by a narrow prosternal process, middle coxe large, globose, remote; mesosternum and meta- 
sternum short; 1st abdominal segment as long as the 2nd and 3rd together, its intercoxal process acute. 
Tibiee curved, the upper margin rounded and serrate, lower apical angle with a short uncus; tarsi with 
joints 1-3 equal, simple. 
Allied to Dryotomus, Chap., and Aricerus, Blandf.; separated from the former by 
the antennal club, which in Dryotomus is constructed as in Phieotribus, and by the 
less remote anterior coxe; from Aricerus, an Australian genus, it is distinguished by 
the transverse apical joint of the club, the structure of the anterior tibiae, and the 
simple 3rd tarsal joint. 
1. Kulytocerus championi, sp.n. (Tab. VI. figg. 19; 19a, antenna.) 
Oblongo-ovalis, subopacus, brunneus, breviter pilosus ; prothorace transverso, lateribus valde rotundatis, dense 
rugoso-punctato, linea media elevata levi; elytris prothorace latioribus, punctato-striatis, interstitiis 
subconvexis multipunctatis, breviter pilosis, uniseriatim setosis. 
Long. 4 millim. 
Oblong-oval, scarcely shining, brown. Front (¢) excavate to the eyes, the fundus subnitid, finely punctate, 
with short erect pubescence; rostrum tuberculate over mouth, arcuately impressed at base. Prothorax 
transverse, widest before the bisinuate base, the sides strongly rounded and somewhat contracted in 
front, the apex obtuse and subproduced, completely hiding the vertex, and separated from the pleura by 
a distinct though non-bordered flexure ; surface close, with very strong, rugose punctuation, the median 
line elevated, shining, abbreviated. Scutellum minute. Elytra wider than the prothorax and a half 
longer, margined but not crenate at base, the humeral angles obliquely rounded, the sides slightly 
rounded but not narrowed before the hinder third; surface convexly declivous for the hinder two- 
thirds, punctate-striate, the strie not deep, with close, large, subquadrate punctures, interstices narrow, 
slightly convex, shining, finely multipunctate, and very shortly pilose, with scanty uniseriate sete. Legs 
piceous, the tarsi lighter. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example, doubtless a male. Owing to the deep frontal excavation, the 
head is entirely concealed from above as in a Tomicid, though the relationship 
of the genus to Phicotribus is close and unmistakable. The scape is fringed towards 
the apex.
