surface, the head, and legs with sparser, white pubescence, the elytra bare. Head rugose between the 
eyes, the latter large and prominent; rostrum stout, curved, not longer than the head and prothorax, 
seriate-punctate, and sharply tricarinate, smoother at the tip, the antenne inserted at one-third from the 
apex, joint 1 of the funiculus nearly as long as 2-4 united. Prothorax convex, broader than long, 
strongly constricted and much narrowed in front, the sides parallel at the base and rounded before the 
middle; the surface with coarse, deep, scattered punctures. Elytra convex, much wider than the 
prothorax, subparallel before the middle, the basal margin acutely raised, the humeri slightly swollen ; 
coarsely punctate-striate, the interstices smooth and somewhat convex. Femora each with an acute 
tooth, that on the posterior pair very small, the anterior pair moderately clavate ; anterior tibiee strongly 
sinuate; tarsal claws with a long tooth. : 
Length 3, breadth 15 millim. (d.) 
Hab. Mexico, Guanajuato (Sad/é). 
One specimen. ‘This is the only species of the genus known to me with a red head 
and prothorax and blue elytra. It is allied to A. cyaneus, &c. 
28. Anthonomus ceruleus, sp. n. 
Oblong-ovate, shining, black, the elytra blue, the rostrum reddish at the tip, the antenne testaceous at the 
middle. the abdomen fusco-testaceous; the under surface and legs with a sparse white pubescence, the 
prothorax also with a dense line of white pubescence down the middle extending on to the scutellum, 
the rest of the upper surface almost bare. Head foveate above the eyes, the latter somewhat depressed. 
and not prominent; rostrum curved, rather stout, widened at the tip, more than twice the length of the 
prothorax, seriate-punctate, rugulose at the sides, sparsely punctured at the apex, the antenne inserted 
at about the middle, joint 1 of the funiculus nearly as long as 2-4 united. Prothorax convex, broader 
than long, somewhat rounded at the sides, constricted and moderately narrowed in front, coarsely, closely 
punctate. Elytra one-half wider than the prothorax, gibbous, parallel towards the base, the latter 
margined, the humeri swollen and somewhat prominent; coarsely and deeply punctate-striate, the 
interstices smooth and convex. Legs rather stout; femora moderately clavate, each with an acute tooth, 
the tibie sinuous within ; tarsal claws with a long tooth. 
Length 23, breadth 1 millim. 
Hab. Paxama, Bugaba (Champion). 
One specimen. Differs from A. cyanicolor, Gyll., from Antioquia (to judge from 
the description), in having the prothorax less narrowed in front (one-half narrower at 
the apex than at the base in Gyllenhal’s insect), and with a dense line of white 
pubescence down the middle, the elytra narrower, &c. 
A. alboscutellatus-group. 
29. Anthonomus alboscutellatus, sp.n. (Tab. X. figg. 10,104, 2.) 
Short-ovate, convex, eneo-piceous, faintly shining, the antenne (the club excepted) testaceous, the base of 
the femora, and the tibie and tarsi in part, sometimes obscure ferruginous; the elytra with a small 
patch of dense, white, squamiform pubescence on the suture at the base, extending forward over the 
scutellum, the rest of the upper surface bare; the under surface sparsely clothed with white pubescence, 
which becomes denser at the sides. Head almost smooth, foveate above the eyes, the latter narrowly 
separated ; rostrum curved, stout, slightly longer than the head and prothorax, coarsely seriate-punctate 
and 5-carinate, confusedly punctured and shining at the tip, the sc:obes descending to beneath the 
eyes, the antenne inserted at about two-fifths from the apex, joint 1 of the funiculus nearly as long 
as 2-4 united, 3-7 short and transverse. Prothorax transverse, rounded at the sides, narrowed and 
constricted in front, strongly bisinuate at the base, closely, coarsely punctate. Elytra considerably wider
