ANTHONOMUS. 189 
this being condensed in places in some specimens, forming three faint vitte on the prothorax and numerous 
scattered spots on the elytra; the under surface densely pubescent at the sides. Head rugulose, faintly 
foveate above the eyes; rostrum (d) moderately curved, much longer than the head and prothorax, 
rugulosely punctate and very finely carinate, smoother and shining at the tip, (2) a little more elongate 
and smoother, and with the apical half shining, the scrobes descending to the lower edge of the eyes, the 
antenne inserted at about one-third from the tip in the ¢ and at a little before the middle in the @, 
joint 1 of the funiculus as long as 2 and 3 united, joints 3-7 about as long as broad, the club narrowly 
ovate. Prothorax transverse, rounded at the sides, narrowed and moderately constricted in front and a little 
narrowed behind, the surface densely punctate. Elytra moderately long, much wider than the prothorax, 
subparallel towards the base, shining, the humeri rounded ; deeply punctate-striate, the interstices convex 
and faintly punctulate. Femora each with a narrow acute tooth, the anterior pair moderately clavate ; 
anterior and intermediate tibiz sinuate within, posterior tibiw triangularly dilated on the inner side near 
the base in the ¢ ; tarsal claws with a long tooth. 
Length 2-3, breadth 1-14 millim. (¢ 9.) 
Hab. Guatemata, Mirandilla (Champion); Panama, Bugaba, Volcan de Chiriqui, 
David, Tolé, Petia Blanca (Champion). 
Numerous examples from the State of Panama, two only from Guatemala. A small 
species, ferruginous in colour, with a common, dark triangular patch at the base of the 
elytra and often a dark spot or fascia on the disc beyond it; the femora each with a 
single sharp tooth; the pubescence moderately close, and sometimes condensed into 
three faint vittz on the prothorax and numerous spots on the elytra. The specimens 
with infuscate rostrum may be discoloured. 
64. Anthonomus isthmicus, sp.n. (Tab. XI. fige. 9, 9a, b, 3.) 
Subovate, moderately shining, obscure ferruginous, the legs and antenne paler, the club of the latter black, 
the elytra with the suture, and in some specimens a patch on the disc beyond the middle, infuscate or 
black, the sutural stripe sometimes dilated anteriorly into a common triangular patch; clothed with fine 
greyish or yellowish-grey pubescence, this being denser and whiter at the sides of the body beneath, and 
sometimes condensed into a few spots on the elytra. Head rugulose, dull, faintly foveate above the eyes; 
rostrum (¢) not longer than the head and prothorax, rugulose and very finely carinate, smoother and 
shining at the tip, (2) a little longer, smoother, and more curved, the antenne inserted slightly before 
the middle in the 2 and at about one-third from the apex in the d, joint 1 of the funiculus almost as long 
as 2-4 united, joints 3-7 short, the club narrowly ovate. Prothorax transverse, rounded at the sides, 
narrowed and slightly constricted in front, densely punctate. Elytra one-half wider than the prothorax, 
moderately long, subparallel towards the base, the humeri rounded; deeply punctate-striate, the interstices 
feebly convex and rugulose. Femora each with a narrow acute tooth ; tibiz sinuous within, the posterior 
pair sharply, triangularly dilated on the inner side a little beyond the middle in the ¢ ; tarsal claws with 
a long tooth. 
Length 2-24, breadth 1-1? millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui, Tolé, Petia Blanca (Champion). 
Nine specimens. Nearly allied to A. triangulifer, differing from it in the shorter 
rostrum and antenne, the dark elytral suture (the triangular patch at the base, at 
most, faintly indicated), and the sharply, triangularly dilated hind tibie in the male, 
the dilatation arising beyond (instead of before) the middle. The pubescence is 
rather sparse above, not hiding the sculpture.
