70 RHYNCHOPHORA. 
1 and 2 separated by a deep sinuous suture. Legs stout, the femora coarsely punctate and very finely 
granulate. 
Length 8-82, breadth 33-3,%, millim. (d 2.) 
Hab. Costa Rica, San José 1135 metres, La Palma 1600 metres (Biolley). 
Five specimens. “More robust than A. articulatus, the prothorax less dilated at 
the sides and more sparsely granulate, the tubercles of the elytra rounded, larger, and 
fewer in number, the humeri angular and projecting. The elytral elevations are nearly 
as large as in the Mexican A. nodosus. 
9. Anchonus articulatus, sp.n. (Tab. V. figg. 7, 7a, b, 2.) 
Oblong, rather broad, black, the funiculus and tarsi obscurely rufescent; the sets very short, fine, and 
scattered. Rostrum (¢) stout, curved, cylindrical, coarsely, closely punctate, (2) thickened towards 
the base, shining, and more finely punctate at the tip; antenne stout, joints 7 and 8 of the funiculus 
transverse, 8 much broader than 7. Prothorax about as broad as long, arcuately dilated at the sides, 
sinuously narrowing behind and abruptly narrowed and constricted in front, the hind angles rectangular ; 
the surface closely, somewhat coarsely granulate, except along a narrow smooth space down the middle, 
the flanks.and base punctate. Elytra ovate, convex, at the middle broader than the prothorax, but at the 
base of nearly the same width ; seriate-punctate, the interstices 2~7 each with a row of oblong or rounded, 
scattered, setigerous, moderately prominent tubercles, the humeri obtuse. Beneath very coarsely punc- 
tate, the ventral segments 1 and 2 separated by a deep suture. Femora coarsely punctate and very 
finely granulate. 
Length 64-8, breadth 31-31 millim. (¢ 2.) 
Hab. Panama (Mus. Brit.), Volcan de Chiriqui 3000 feet (Champion). 
Three males and two females. Differs from A. diolleyi, with which it agrees, in 
having the first and second ventral segments separated by a deep suture, by the obtuse 
humeri, &c. The prothorax is sinuously narrowed behind, so that the hind angles are 
rectangular, as viewed from above; the disc is closely granulate, except along the 
middle. 
8. Anchonus brevisetis, sp. n. (Tab. V. figg. 8, 8a, 2.) 
Oblong, black, the antenne and tarsi obscurely rufescent, the surface usually coated with an earthy incrustation ; 
the setee very short, fine, and scattered, not forming fascicles on the prothorax or elytra. Rostrum (¢) 
stout, curved, cylindrical, closely and rugosely punctured to the tip, not carinate, ( 2 ) thickened towards 
the base, shining and more finely punctate at the tip; antenne stout, joint 2 of the funiculus nearly 
twice as long as 1, 7 and 8 transverse, 8 much broader than 7. Prothorax broader than long, somewhat 
flattened on the disc, strongly constricted and narrowed in front and much narrowed behind, the sides 
rounded at the middle; the entire surface closely varioloso-punctate, the very narrow raised interspaces 
smooth, shining, and sinuous (appearing more or less granulate through the earthy incrustation), the disc 
sometimes with indications of an abbreviated median carina. LElytra ovate, convex, at the middle 
considerably wider than the prothorax, but very little broader than it at the base, the basal margin raised 
and sinuous ; seriate-punctate, the interstices 2-7 each with a series of small setigerous tubercles, those 
at the base of 3 and 5 sometimes forming a short ridge. Beneath very sparsely punctate. Ventral 
segments 1 and 2 separated by a rather deep suture. Femora coarsely punctate. 
Length 53-72, breadth 23-34 millim. (¢ 2.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).
