176 RHYNCHOPHORA. 
and there a little more raised, especially towards the base. Pygidium exposed, vertical. Fifth ventral 
segment broadly and shallowly emarginate at the apex. Anterior femora with a large triangular tooth 
and a minute one exterior to it, the intermediate and hind femora each with a single long tooth; tibi 
sinuate on their inner edge, the anterior pair strongly so; tarsal claws with a moderately long tooth. 
Length 44, breadth 23 millim. (<d.) 
Hab. Mexco, Cuernavaca (Sallé). 
One specimen. Distinguished by its rather broad form, dull, rugulose surface, 
the coarsely punctate-striate elytra, which are subfasciate and have strongly convex, 
somewhat uneven interstices, and flavo-annulate intermediate and hind femora and_ 
tibie. 
36. Anthonomus alternans, sp. n. (Tab. X. figg. 15, 15a, 2.) 
Subovate, piceous, the antennal scape testaceous ; the legs black, the tibize and tarsi, and the base of each of 
the four hinder femora, annulated with flavo-testaceous ; somewhat sparsely clothed with greyish-ochreous 
pubescence, which is condensed into a narrow vitta along the middle of the prothorax and into several 
scattered spots on each of the alternate elytral interstices, the vestiture of the scutellum and under surface 
paler. Head rugulose, foveate, the eyes prominent; rostrum strongly curved, not very stout, longer 
than the head and prothorax, shining, finely seriate-punctate, smoother in its outer half, the antenne 
inserted about the middle, joint 1 of the funiculus a little longer than 2-4 united. Prothorax transverse, 
rounded at the sides, narrowed and constricted in front, densely, finely punctate. Elytra comparatively 
short, convex, one-half wider than the prothorax, subparallel at the base, the humeri prominent; deeply 
punctate-striate, the interstices strongly convex and punctulate. Femora each with an acute triangular 
tooth, that on the anterior pair stout, the latter somewhat strongly clavate; anterior tibie sinuate 
within ; tarsal claws with a long tooth. 
Length 3, breadth 14 millim. (Q.) 
Hab. Guatemaus, Cerro Zunil 4000 feet (Champion). 
One specimen. ‘This species is perhaps nearest allied to A. annulipes, differing from 
that insect in its much smaller size and less elongate shape, the strongly curved rostrum, 
the tessellated arrangement of the elytral pubescence, &c. 
A. cyanipennis-group. 
37. Anthonomus cyanipennis, sp.n. (Tab. X. figg. 16, 16a, 3.) 
Subovate, shining, black, the elytra cyaneous, the antennal scape, and the intermediate and hind femora to 
near the apex, rufo-testaceous, the anterior femora at the extreme base in the 2 and to beyond the 
middle in the ¢ similarly coloured; very sparsely clothed with fine grey pubescence, which is a little 
condensed along the middle of the prothorax, that of the under surface slightly coarser and whiter. 
Head finely foveate above the eyes, the latter large and prominent; rostrum (¢) rather longer than the 
head and prothorax, curved, seriate-punctate, sparsely punctured at the tip, (2) longer and smoother, 
the antenne inserted at about one-third from the apex in the ¢ and slightly before the middle in the 9, 
joint 1 of the funiculus as long as 2-4 united, the club loosely articulate. Prothorax broader than long 
rounded at the sides, constricted and much narrowed in front, densely punctate. Elytra one-half wider 
than the prothorax, convex, narrowing almost from the base, the humeri obtuse, but prominent; deeply 
punctate-striate, the interstices strongly convex and faintly punctulate. Anterior legs very elongate, the 
others much shorter; all the femora somewhat strongly clavate, and each with an acute tooth, that on 
the anterior pair long; anterior tibiee strongly sinuate within, posterior tibie sharply mucronate at the 
apex, the others unguiculate ; tarsal claws with a long tooth. 
Length 23-3,45, breadth 13-13 millim. (¢ 9.)
