CURCULIONIDiE. 
Im. 93 
Gryptorrhy nchides . 
J. L. Leconte, P. Am. Phil. Soc. xv. p. 223, et seq., discussing the N. 
American species, establishes a new group, Acampti, for a new genus, in 
which the pectoral groove is confined to the prosternum and open behind, 
the rostrum is broad, and the tarsi are narrow. Schonherr wrongly states 
that the antennae in Conotrachelus are “ longe medium rostri sitae”; 
he should have written “ ultra.^’ Chalcodermus pruinosus^ Boh., is re- 
moved to Bhi/ssematus, in which the claws are cleft, and the two outer 
striae of the elytra are separated by a costa. Tyloderma, Say, 1831, is 
restored for Analcis, Sch., 1837, and these names stand also for "Bub- 
genera. Cryptorrhynchus ohlique-fasciatus^ Boh., = luctuosus, Boh., var., 
= bisignatus, Say. 
Ithyporus Lucas, is wrongly placed in the Cry ptorrhy nchides, 
being closely allied to Trachodes ; L. Bedel, Bull. Soc. Ent. Pr. (5) vi. 
p. Ixxi. 
New genera and species 
Micralcinus, Leconte, 1. c. p. 235. Ithypori : resembles Tyloderma ; 
closely allied to Conotrachelus, but of different shape, emarginate at base, 
with shorter rostrum and untoothed claws. For M. crihratus, p. 236, 
Florida. 
Zaglyptus, id. 1 . c. p. 236. Resembles miniature Rhyssematus, but with 
slender simple tarsi and different antennae. For Z. sulcatus, Alabama, 
and striatus, Pennsylvania, p. 237. 
Microhyus, id. 1 . c. p. 237. Resembles small Conotrachelus, but with 
simple divergent claws and different funiculus. M. setiger, p. 238, 
Georgia. 
Acamptus, id. 1. c. p. 238. Acampii : differs from the Ithyporides as 
Camptorrhinus does from the true Cry ptorrhy nchides, by the shorter 
rostrum resting on the front coxae. Body elongate, tibise stout, sinuate 
internally, strongly hooked at tip ; tarsi not dilated or spongy beneath, 
antennae with pubescent club. Relations indicated with Byrsopides and 
Cossonides. For A. rigidus, p. 239, S. Carolina to Texas. 
Eur\y]hoptus, id. 1. c. p. 245. Cryptorrhynchi : differs from Acalles in 
the club of the antennae, which is stouter, less elongate, and annulated 
only near the tip. For E. pyriformis, ibid., Illinois. 
Micromastus, id. 1 . c. p. 246. Differs from Acalles in the mesosternum 
being small, and very slightly prominent, and the larger, divergent claws. 
For Crypt, gracilis. Boh. 
Phyrdenus, id. 1 . c. p. 249. Form of Conotrachelus, but with pectoral 
canal as in Cryptorrhynchus ; claws broadly appendiculate at base. For 
P. undatus, ibid., Missouri, Georgia, Texas. 
Zascelis, id. 1 . c. p. 256. Allied to Cnema,rgus and Enteles, but with 
toothed tibiae. For Z. serripes, squamigera, and irrorata, p. 257, California. 
Bar[i(r\opsis, id. 1. c. p. 258. Differs from Codosternus essentially 
in the first ventral suture being more distinctly sinuate and nearly oblite- 
rated in the middle, with the second segment as long as the two following 
united. Facies of Tyloderma, sculpture of Baris. For Bar \id~\ oq)sis 
crihratus, p. 259, Kansas and Texas.
