WILLIAM G. DIETZ. 
slightly dehiscent and completely covering the pygidinm ; striie very 
fine, punctures small, not closely approximate; interspaces flat. 
Prosternum short in front of the coxie ; middle coxie subcontiguous, 
that is, very narrowly separated by the mesosternum, which ends in a 
point, and does not articulate with the metasternum behind. Meta- 
sternum long ; posterior cox?e not widely separated ; v'entral segments 
subequal, third and fourth but little shorter than the second ; fifth a 
little shorter than the preceding segment in the S and of about 
equal length in the 9 • Pygidinm concealed by the elytra and 
scarcely visible from below. Legs long and slender ; thighs feebly 
clavate, inutic. Tibiie slender, somewhat attenuate in their distal 
half, all armed with a hook at the ajiex, which is quite large and 
projecting at the anterior pair. Tarsi long and slender, first and 
second joints elongate triangular; third joint short, bilobed, lobes 
small, round ; fourth joint very long and slender, about as long as 
the three preceding joints together. Claws long and slender, slightly 
divergent, and armed with a long, slender tooth. 
This new genus is established upon an elongate, densely squamous 
species, remarkable for the construction of the antennal club and 
the almost contiguous middle coxie.
