The distribution of species in America and Burma, and their extra- 
ordinary mixture of characters, indicate the preservation of an ancient 
form, out of place in any linear arrangement. J. L. Leconte, P. Am.

Oeuthorrhynchides. 
Mononychus is separated as type of a tribe Mononychi, in which the 
pygidium is not carinate in front, and has no transverse line for the 
reception of the tip of the elytra. Cosliodes epilobii^ Gyll., occurs at 
Great Slave Lake and in British Columbia, and is made type of a new 
genus. Ceuthorrhynchus rapes, Gyll., Phytobius velatus, Gyll., and 
Rhinoncus pericarpius, Gyll., occur in N. America. J. L. Leconte, 1. c. 
pp. 267, 271, 274, 281, & 284. The following new genera and species 
are described by him : — 
Craponius, p. 268. Differs fi’om Coeliodes in its tibiae being flattened, 
and toothed and broadly grooved on the outer side, and in its pectoral 
groove extending to the metasternum. For Ceuthorrhynchus incequalis, 
Say. 
Cnemogonus, p. 269. Differs from Cceliodes in its tibiae being much 
flattened and dilated externally, so as to form a largo angle near the 
knee ; also in the untoothed femora, and the claws being armed with a 
short tooth, not cleft. From Craponius, it differs in the ungrooved tibiae, 
and in the pectoral groove not being prolonged into the metasternum. 
For Cceliodes epilobii, Payk. 
Acallodes, p. 271. With the pyriform body of Scleropterus, but the 
funiculus has seven distinct joints, &c. For A. ventricosus, p. 272,
