nentibus : prothorace cylindrico-ovato, antice et postlce 
truncato, mox pone apicem leviter transversim constricto : 
scutello subrotundato, valde distincto : metasterno elon-

versus apicem rostri insertas ; scapo elongate, curvato, 
gradatim valde clavato ; funiculo 7-ai'ticulato, brevi, 
art.° 1""° subquadrato, vix incrassato, sequentibus brevissi-

antici minus et postici magis inter se separati) : tibiis 
(praesertim anticis) robustis, et ad apicem externum in 
uncum magnum deflexum productis : tar sis elongatis, 
latiusculis, pilosis, art." 1"'° elongato. 3*'° sensim latiore ac

Obs. — Genus prsecipue insignum rostro brevissimo 
crasso, sed tamen parallelo (nee triangulari), antennis 
crassis, scapo elongato, funiculo brevi, et capitulo per- 
magno rotundato abrupto, oculis prominentibus, pedibus 
ad basin subaequaliter separatis (sc. anticis magis sed pos- 
ticis minus remotis quam in Cossonidis plerisque obtinet), 
corpore subtus distincte breviter pubescente, tarsisque 
latiusculis pubescentibus, articulo primo elongato, tertio 
sensim latiore ac conspicue bilobo. 
A a-(paiga, globus, et KO^uvri, clava. 
A well-defined genus, whicli may at once be recognized 
by the shortness and thickness of its rostrum (which is 
nevertheless parallel, and not triangular as in Stenoscelis^, 
by its thickened antennje having their scape elongate and 
very robust, their funiculus short, and their club extremely 
large, rounded, and abrupt, by its tarsi (the first joint of 
which is lengthened, and the thu'd bilobed) being rather 
broad and pubescent, and by the fact of its legs being 
suhequally distant at their base, — the anterior pair being 
less approximated, and the hinder ones more so, than is 
usually the case iu the Cossonidce. And it is further 
remarkable for its body (which is nearly cylindrical, and 
with the eyes prominent) being sparingly clothed beneath 
with a fine and short pile ; and for its front tibias being 
somewhat widened, flexuose, and robust, with their apical 
hook largely developed.
