LONCHOPHORUS.—ANTHONOMUS. 155 
declivous towards the apex, rapidly narrowing from the rounded, prominent humeri, transversely 
depressed on the disc a little below the base, the suture also depressed in front, the basal margin raised ; 
punctate-striate, the strie coarsely punctured and deeply impressed at the base, the interstices smooth, 
almost flat, becoming convex at the base and apex, the fifth much raised at its point of termination. 
Femora cach armed with an acute tooth; tarsal claws with a long tooth. 
Length 3{-53, breadth 14-23 millim. (¢ 2.) 
Hab. Mexico (Mus. Brit.), Orizaba (Sallé), Jalapa (Héye), Teapa (H. H. Sinith) ; 
GuaTEMALA, Las Mercedes, Cerro Zunil, Sinanja (Champion); Panama, Volcan de 
Chiriqui (Champion).—CoLomBla. 
Numerous examples, varying greatly in size and colour. Easily recognizable by 
the sparse white pubescence, shining surface, and elongate-triangular elytra, the filth 
interstice of the latter sharply raised at its apex. The femora are unidentate. 
_  ANTHONOMUS. 
Anthonomus, Germar, Mag. Ent. iv. p. 320 (1821) ; Lacordaire, Gen. Col. vi. p. 581; Desbrochers 
des Loges, Ann. Soc. Ent. Fr. 1868, p. 411; Leconte, Proc. Am. Phil. Soc. xv. p. 194 (part.) ; 
Dietz, Trans. Am. Ent. Soc. xviii. p. 188 (part.). 
This genus includes a very large number of species, being especially well represented 
in America north of Mexico, whence Dietz recognizes eighty-two as distinct, which he 
places under nine subgenera, fifty-four of the former being referred to Anthonomus, 
s. str. The Central-American forms, most of which are treated as new, are almost 
equally numerous and of a very heterogeneous character, many of them differing greatly 
in general facies, but not in structure. As adopted here, Anthonomus (after the exclu- 
sion of the preceding genera, the characters of which have already been noticed) is 
restricted to those species with the funiculus 7-jointed (various forms with a 6-jointed 
funiculus are included by both Leconte and Dietz*), the tarsal claws toothed, the 
posterior tibiae unarmed or simply mucronate at the apex, and the femora bi- or 
unidentate, the hind pair sometimes unarmed. ‘The scrobes are usually lateral, but 
they sometimes descend to beneath the lower limit of the eyes in the species with 
a stout, curved, comparatively short rostrum (A. puncticeps &c.), and the length of the 
antennal club is also variable, being long and loosely articulated in the forms with 
long and slender antenne. . 
To facilitate their identification, the Central-American species are here arranged 
under “groups,” based mainly upon their general facies, rather than upon their 
structure, all attempts ‘at briefly tabulating them by their essential characters only 
having proved unsatisfactory, or of little practical value to the student. 
A. Elytra more or less tuberculate or nodose, at least towards the base ; 
autcrior femora much thickened, bi- or unidentate ; antennal club 
loosely articulated. [Subgen. Leprarrurvs, Dietz. | 
* Fifteen species with a 6-jointed funiculus are included by Dietz. _
