ANCHONUS. 85 
35. Anchonus affinis, sp. n. 
Obovate, black, the antenne and tarsi obscurely rufescent, thickly coated with an earthy incrustation ; the 
sete short and abundant. Rostrum stout, curved, cylindrical, feebly constricted at the base, closely 
seriate-punctate. Prothorax transverse, rather convex, the sides rounded at the middle, converging 
thence to the base and apex, and constricted in front; the entire surface closely, uniformly punctate. 
Elytra oblong-ovate, at the base wider than the prothorax; seriate-punctate, the interstices 2-7 each 
with a series of feeble, oblong, granulate elevations, those at the base of 3 and 5 cariniform. 
- Length 4, breadth 23 millim. (¢.) 
Hab. GuatemaLa, Cerro Zunil, Pacific slope (Champion). 
One specimen. Extremely like A. puncticollis, but differing from it in having the 
prothorax less rounded at the sides behind, the elytra oblong-ovate in shape, with the 
interstices 2-7 feebly seriato-tuberculate, the tubercles granulate, and those on 3 and 5 
not larger than the rest, the elytral setze shorter and not so coarse. 
36. Anchonus hirsutus, sp. n, 
Oblong-ovate, black, the apex of the rostrum, the antennsw, and tarsi more or less rufescent; the sete rather 
short, semi-erect, and abundant. Rostrum curved, moderately stout, slightly thickened at the base, and 
there feebly constricted, seriate-punctate, shining and smoother at the tip, faintly carinate. Prothorax 
broader than long, somewhat convex, the sides slightly dilated at the middle, rapidly converging in front 
and behind, and constricted before the apex ; the surface closely punctate, the narrow interspaces here 
and there raised and shining, the disc with indications of an abbreviated, very narrow, shining median 
carina. Elytra subelliptic, convex, at the middle very much wider than the prothorax; seriate-punctate, 
the interstices 2-6 each with a scattered series of oblong, moderately prominent, finely granulate 
elevations, those at the base of 3 and 5 cariniform, and 7 more or less distinctly granulate. 
Length 4-41, breadth 2 millim. (@.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Two specimens. The chief characters of this small species are the transverse, closely 
punctate prothorax, in which the narrow sinuous interspaces are here and there raised 
and shining (appearing granulate in places), and the subelliptic elytra, the interstices 
2-6 of the latter with narrow, oblong, moderately prominent elevations, these about 
equal in size. ‘The setosity is short, but conspicuous. In general shape it is more 
elongate than A. hystrix and A. alternans. The following is a very closely allied 
form. 
37. Anchonus subcarinatus, sp.n. (Tab. VI. figg. 7, 7a, 2.) 
Oblong-obovate, moderately convex, black, the apex of the rostrum, the antenne, and legs more or less 
rufescent ; the sete short, coarse, and erect. Rostrum moderately stout, curved, slightly thickened (but 
not constricted) at the base, seriate-punctate, the punctuation becoming finer and more scattered towards 
the apex, shining, not carinate. Prothorax broader than long, a little flattened on the disc, the sides 
rounded at the centre and converging thence towards the base and apex, slightly constricted before the 
middle ; the surface closely, coarsely punctate, with the interspaces narrow and dull. Elytra oblong- 
oval, at the middle very much wider than the prothorax; seriate-punctate, the interstices 3-6 feebly, 
interruptedly costate, 7 granulate, 2 without distinct prominences. 
Length 33, breadth 2 millim. ( 2.) 
Hab. Panama, Volcan de Chiriqui (Champion).
