has very well developed wings, and the elytra not connate.

J. L. Leconte, P. Am. Phil. Soc. xv. pp. 391-409, adopts for the N. 
American species practically the same tribes as those employed by 
Lacordaire, separating, however, as a distinct group, Hormisci, of his 
Tropiderini, the genus Hormiscus of Wollaston and two new genera, 
defined by the emarginate eyes and distinct suture to the mentum. 
Cratoparis is also separated from the Anthrihi, chiefly by the 3rd joint 
of the tarsi being bilobed, not visible from above. Anihrihus cornutus^ 
Say, is wrongly referred to Tropideres by Harold & Gemminger, and A. 
mcestus^ Lee., is not an Arceocerus but a Piazocorynus ; Brachytarsus 
ohsoletus, Fahr., ? = variegatus, Say, var. 
The following new genera and species are described : — 
Gonotropis, p. 393. Differs from Tropideres in the narrow, not com- 
pressed club of its antennae. G. gibbosus, p. 394, Colorado. 
Eurymycter, p. 394. Represents the European Platyrrhinus, but with 
the rostrum narrower than the head and strongly dilated at the tip. 
Differs from its ally Gonotropis in the prothoracic ridge being straight 
in the middle, with the base deeply bi-emarginate, and in the acutely 
toothed claws. For Macroceplialus fasciatus^ 01. 
A /ZcmcZrws, p. 396. Tropiderini: differs from J'rop^c?eres in its longer 
rostrum, very long antennae in the $ , and rounded eyes. A. bifasciatus^ 
ibid., Canada, Illinois. 
Toxotropis, p. 397. Ilormisci : differs from Hormiscus in its elongate- 
oval compressed club, which is composed of 3 distinct joints equal in 
length. For T. pusillus^ Florida, and approximatus, California, p. 398. 
Gonops, p. 398. Differs from Toxotropis in its strongly emarginate 
eyes, and claws cleft almost to the base, with the inner portions converg- 
ing as in Anthonomus. For G. Jissunguis, ibid., California. 
Eusphyrus, p. 399. Anthribi : eyes emarginate, hind angles of pro- 
thorax directed outward ; front coxae contiguous. For E. walshi, p. 400, 
Illinois. 
Phcenicobius, p. 400. Allied to the preceding: claws almost cleft, 
body elongate-cylindrical, hind angles of thorax not directed outward. 
P.chamceropis, p. 401, Florida. 
Anthribuhis, p. 406. Bracliytarsi : differs from Brachytarsus in the 
basal ridge of the prothorax being gently rounded and becoming obsolete 
at the hind angles. A. rotundatus, p. 407, Massachusetts to Louisiana. 
Euxenus, p. 409. Xenorchestini : prothorax punctured, elytra with 
irregular double rows of punctures [only specific characters]. For E. 
punctatus, p. 409, Michigan, Canada. 
Tropideres rectus, p. 395, Florida.
