72 RHYNCHOPHORA. 
these forming carine at the base of 3 and 5, and all finely granulate. Beneath and the femora coarsely 
punctate. Third tarsal joint moderately dilated, not very deeply excised at the apex. 
Length 6-64, breadth 23-24 millim. (<.) 
Hab. Muxico, Mexico city (Hoge). 
Three specimens. Allied to the Guatemalan A. mirus, but less elongate, with the 
rostrum shorter and slightly constricted at the base, the antenne not quite so stout, 
the prothorax less rugose, with much more definite punctuation, the elytra with less 
prominent, finely granulate elevations. The distinctly constricted rostrum and the 
form of the antenne, &c. separate it from A. elongatus and various other Mexican 
forms. In dirty specimens the small, smooth, granular elevations are conspicuous on 
both the prothorax and the elytra. 
6. Anchonus gibbirostris, sp. n. (Tab. V. figg. 11, lla, 8, ¢.) 
Elongate, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the setee rather long and coarse, 
and arranged into fascicles on the prothorax and elytra. Rostrum (¢) stout, cylindrical, strongly 
curved, gibbous above near the base, densely, rugosely punctate and minutely granulate to the tip, 
(2 ) coarsely, closely punctate, smoother at the tip. Prothorax slightly longer than broad, narrowed behind 
and constricted in front, flattened on the disc, the sides rounded at the middle; the surface irregularly 
granulate, except along the depressed median space and a sinuous space midway between this and the 
margin, which are smooth, and with two more or less distinct setigerous elevations at the apex and two 
more on the disc; the flanks coarsely punctate. Hlytra ovate, convex, wider than the prothorax, but of 
about the same width at the base, interruptedly seriate-punctate, the interstices 2-7 each with a scattered 
series of oblong or rounded, prominent, setigerous, faintly granulate tubercles, the basal margin raised. 
Beneath very coarsely, sparsely punctate. Femora coarsely punctate and minutely granulate. 
Length 54-64, breadth 23-3 millim. (¢ 9.) 
Hab. GuateMaLa, Senahu and San Juan in Vera Paz (Champion). 
Twelve specimens, from a limited district in the forest-clad mountains to the north 
of the Polochic Valley. Distinguishable from all the other Central-American species of 
the genus by the gibbous rostrum. The elevations on the prothorax are partly formed 
by the fasciculate arrangement of the sete, those on the elytra being more prominent. 
The rostrum is not constricted at the base. 
7. Anchonus nodosus, sp. n. (Tab. V. figg. 12, 124, ¢.) 
Anchonus nodosus, Chevr. in litt. 
Elongate, very convex, black, the antenne and tarsi obscurely rufescent; the sete very short and scattered. 
Rostrum (¢) stout, cylindrical, strongly curved, coarsely punctate to the tip, feebly constricted at the 
base, ( 2 ) slightly thickened towards the base, and smoother and more shining at the apex; joint 2 of 
the funiculus twice as long as 1. Prothorax about as broad as long, nearly or quite as wide as the 
elytra, strongly constricted behind and also before the apex, the sides rounded ; the surface very uneven, 
coarsely nodose and granulate laterally and also along either side of the depressed median space, for the 
rest smooth ; the flanks coarsely punctate. LElytra at the base very little wider than the prothorax, 
convex, ovate; each with about twelve very prominent, large, rounded or oblong, granulate elevations on 
the dise and scattered smaller tubercles towards the sides, between which seriate punctures are visible. 
Beneath shining, very coarsely punctate. Femora granulate. 
Length 7-10, breadth 3}-43 millim. (¢ 2.)
