Hylohiides, 
Hylohius abietis and pinastri differentiated, the latter occurring at 
about the rate of 10 per cent, compared with the former ; Kellner, in 
Protokoll der 15 Versammlung thuringischer Forstwirthe, 1875, p. 17, 
quoted in Ent. Nachr. ii. pp. 53-55. 
Lepyrus is associated with Phytonomus in a tribe Phytonomini of sub- 
fam. “ Curculionidse genuini ’’ (anted, p. 76). It differs from Hylohius in 
the form of the mandibles, which are simply emarginate, the oblong and 
rather large mentum, the much smaller ligula and palpi, and in the 
oblique form of the articular surface of the tibiae. L. colon occurs in 
Hudson’s Bay Territory. J. L. Leconte, P. Am. Phil. Soc. xv- 
p. 127. 
Leconte, 1. c. p. 137, associates Plinthus with recognized and new N. 
American genera as a tribe Hylohiini of the same subfamily. Pissodes 
should possibly be placed as a separate tribe, p. 142. 
Hypomolyx, g. n., Leconte, 1. c. p. 139. Thighs feebly clavate, not 
toothed, eyes small, elytra oval, convex. For Hylohius pinicola, Couper. 
Pachylohius, g. n., id. ibid. Differs from Hylohius in its much shorter 
and stouter tibiae, which are expanded at the tip, so that the corbels are 
much wider. For Hylohius picivorus, Germ. 
Pissodes fasciatus, Oregon, rotundatus, Lake Superior, spp. nn., id. 1. c.

Erirrhinides. 
J. L. Leconte, P. Am. Phil. Soc. xv. pp. 160-189, on the authority of 
Tychius amosnus, Say, and a new sp., includes Pachytychius, Jekel, in a 
new group Desmorrhines of his tribe Erirrhinini, which comprehends all 
Lacordaire’s groups, with others. The Desmorrhines include Smicronyx, 
besides the new typical genus, and have the rostrum strongly constricted 
at the base, and the claws connate or approximate. Stenopelmus, Sch., 
was unnecessarily renamed Monius by the author, and is removed from 
Lacordaire’s Storeides to form a separate group Stenopelmi, with simple 
3rd joint to the tarsi and short stout rostrum, diverging towards Prio- 
nomerus in the form of the head and antennae. Two new genera, appa- 
rently allied to Brachypus, constitute with that genus a distinct group, 
Brachypi, of narrow linear form, differing from the Hydronomi in the 
more or less bilobed 3rd joint of the tarsi, and truncate apex of the hind 
tibiae, which are only feebly mucronate. Another new group is Phy- 
cocoeies, with very short meso-sternum. Procas picipes, Steph., Grypidius 
equiseii, and hrunnirostris, Gy 11., and Tanysphyrus lemnce, Gyll., are 
recorded from N. America. Anthonomus tessellatus, Walsh, is a Dory- 
tomus, and is renamed squamosus, p. 166. Tychius corniculatus, Fahr., is 
a Smicronyx, p. 173.
