ANTHONOMUS. 167 
by its oblong shape, gibbous prothorax and elytra, and shining black surface, the suture 
of the elytra depressed at the base, the depression clothed with a line of dense white 
pubescence. 
16. Anthonomus aterrimus, sp. n. (Tab. X. figg. 2, 2a, 4, 2.) 
Obovate, very shining, black, the basal joint of the funiculus and the scape of the antenne ferruginous, the 
femora sometimes rufo-piceous at the base; the elytra with a line of dense white pubescence along 
the suture in front, extending forward over the scutellum to the base of the prothorax, and also with a 
line of white pubescence near the apical margin; the prothorax with long white hairs at the base and 
sides; the head, under surface, atid legs with scattered, and the metasternal side-pieces with a dense 
line of, white pubescence. Head thickly punctured, foveate above the eyes, the latter large ; rostrum 
moderately curved, rather stout, slightly longer than the head and prothorax, in the ¢ seriate-punctate 
and feebly carinate, with the tip sparsely punctate, in the 2 smoother, the antennae inserted at about 
one-third from the apex in the ? and a little more forward in the ¢, joint 1 of the funiculus nearly as 
long as 2-4 united. Prothorax broader than long, transversely convex, rounded at the sides, constricted 
and narrowed in front, and narrowed behind, coarsely punctate. Elytra rather short, much wider than 
the prothorax, gibbous, the suture depressed at the base, the latter sharply margined, the humeri obtuse 
and a little swollen; very finely and lightly punctate-striate, the striz deeper at the extreme base, the 
interstices smooth and flat. Femora each with an acute triangular tooth, the anterior pair strongly 
clavate and with a small additional tooth exterior to the other ; anterior tibie sinuate within ; tarsal claws 
with a long tooth. 
Length 24-22, breadth 13-13 millim. (¢ 9.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Seven specimens. Very like some of the small species of Otidocephalus inhabiting 
the same region. Less elongate than A. funereus, the elytra much shorter, the anterior 
femora bidentate, the last-mentioned character and the gibbous elytra separating it 
from A. mexicanus and other allied forms. 
A. albolineatus-group. 
17. Anthonomus albolineatus, sp. n. 
Oblong-ovate, shining, black or piceous, the antenne (the club excepted) rufo-testaceous ; very sparsely clothed 
with rather coarse white decumbent pubescence, which is more or less condensed down the middle and at 
the sides of the prothorax and arranged in interrupted lines on the elytra, becoming evanescent on the 
dise anteriorly, the suture of the latter at the base, the scutellum, and sternal side-pieces densely, and 
the rest of the under surface somewhat thickly, pubescent. Head sparsely punctate, foveate above the 
eyes, the latter large and somewhat narrowly separated; rostrum ( ¢ ) moderately curved, much longer 
than the head and prothorax, seriate-punctate, sparsely punctured at the tip, (@ ) longer and smoother, 
the antenne inserted near the middle in the and at about two-fifths from the apex in the ¢, joint 1 
of the funiculus not longer than 2 and 3 united. Prothorax convex, slightly broader than long, rounded 
at the sides, much narrowed and feebly constricted in front, coarsely, rather sparsely punctate. Elytra a 
little wider than the prothorax, oblong, convex, sharply margined at the base, the humeri swollen, rounded, 
the suture slightly depressed in front ; punctate-striate, the interstices moderately convex and faintly 
punctulate. Anterior femora somewhat strongly clavate and with a stout triangular tooth, the other 
femora with an acute tooth ; anterior tibie strongly sinuate within ; tarsal claws with a long tooth. 
Length 34-44), breadth 13-13 milim. (3 ¢ .) 
Hab. Mexico, Orizaba (Sallé); GUATEMALA, Cubilguitz in Vera Paz (Champion). 
Four specimens. Very like A. funereus, but with the elytra less gibbous, more
