136 RHYNCHOPHORA. 
PYR/ECHMES, gen. nov. 
Rostrum stout, curved, widened at the apex, as long as the prothorax, slightly constricted at the base, the 
scrobes descending at once, their anterior opening visible from above ; antenne inserted near the apex of 
the rostrum, rather long, the funiculus 7-jointed—joint 1 stout, 2-7 very gradually widening,—the club 
ovate, shining, and sparsely pubescent; eyes transverse, finely facetted ; prothorax convex, nearly as 
long as broad; scutellum not visible ; elytra oblong, much wider than the prothorax, with very prominent, 
obliquely truncated humeri; prosternum emarginate at the apex, short, flattened in front ; anterior coxe 
contiguous, the intermediate pair narrowly, the hind pair very widely, separated; ventral segments 1 
and 2 very short, the sutures straight ; femora moderately incrassate, unarmed ; tibize curved, stout, 
sinuous within, obliquely truncated at the apex, armed with a long claw at the inner apical angle, and 
also feebly mucronate; tarsi short and stout, smooth, joint 2 transverse, 3 broad and bilobed, 4 slender, 
extending considerably beyond the apex of 3, the claws small, divergent, and unarmed; body oblong- 
ovate, covered with a dense clothing of agglutinated scales. 
The single species from which the above characters are taken is related to Onychylis, 
Bagous, and other allied genera, but cannot be included in any of them. The chief 
characters are the short, stout, smooth tarsi, with bilobed third joint and feebly 
developed claws, the apically inserted, rather long antenne, with sparsely pubescent 
club, the long tibial claws, and the rapidly descending scrobes. 
1. Pyrechmes brevitarsis, sp.n. (Tab. VIII. figg. 17, 17 a.) 
Oblong-ovate, nigro-piceous, the tip of the rostrum, the antenne, tibie, and tarsi ferruginous ; the surface 
densely clothed with brownish-grey agglutinated scales, the prothorax with a large patch on the disc 
behind, and the elytra with a common transverse patch at the base and a rather broad transverse fascia 
a little beyond the middle, dark brown, and also with scattered, fine, curled, decumbent sete, which are 
serially arranged on the elytra. Rostrum bare and shining at the tip; joint 2 of the funiculus a little 
longer than 3, and shorter and smaller than 1, 3-7 transverse. Prothorax constricted in front, subparallel 
behind, densely punctate. Elytra one-half wider than the prothorax, subparallel in their basal half, the 
humeri swollen and obliquely truncated ; very coarsely punctate-striate, the interstices rugulose, narrow, 
convex, the alternate ones costate. 
Length 22, breadth 1,45 millim.

This genus, to which six North-American species are referred by Leconte, will 
probably have either to be sunk as synonymous with Tanysphyrus, or restricted to 
those forms with a large terminal joint (6th) to the funiculus, a character possessed by 
the type, E. limatulus (Gyll.). In most or all of the other forms the joints 2-6 of 
the funiculus are sma]l and narrow, as in Tanysphyrus. The tarsi are very stout, the 
third joint dilated and strongly bilobed, the fourth scarcely extending beyond it.
