ANCHONUS. (oy 
12. Anchonus obovatus, sp. n. (Tab. V. figg. 17, 174, 3.) 
Obovate, robust, convex, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the set coarse, 
rather long, forming conspicuous erect fascicles on the prothorax and on the elytra, chiefly placed on the 
elevated portions of the surface. Rostrum stout, curved, cylindrical, closely, rugosely punctate to the tip, 
not carinate; joint 2 of the funiculus about twice as long as 1. Prothorax about as broad as long, 
narrowed and constricted in front and narrowed behind, the sides rounded at the middle; the surface 
closely punctate, in some specimens with a smooth slightly raised median line, binodose and fasciculate at 
the apex, and with two other fascicles on the disc and one on each side before the middle. Elytra ovate, 
convex, at the middle fully one-half wider than the prothorax, but at the base scarcely wider than it, 
seriate-punctate, the interstices 2-6 each with a scattered series of very prominent oblong or rounded 
setigerous tubercles, the suture also tuberculate beyond the middle. Beneath coarsely, sparsely punctate. 
Femora coarsely punctate. 
Length 6-7, breadth 3-34 millim. (d @.) 
Hab. Costa Rica, Tucurrique (Mus. Dresden); Panama, Volcan de Chiriqui 
(Champion). 
Eighteen specimens, mostly in very clean condition. A rather large, convex species, 
of obovate form, with the rostrum coarsely punctate to the tip in both sexes, the 
prothorax coarsely, rugosely punctate and conspicuously fasciculate, and the elytra 
with prominent setigerous tubercles. There is no trace of granulation on the pro- 
thorax, the punctures appearing variolose in dirty examples. 
13. Anchonus validus, sp. n. 
Obovate, robust, convex, black ; the sete coarse and rather long, forming fascicles on the prothorax and on 
the elytra, chiefly placed on the elevated portions of the surface. Rostrum very stout, curved, cylindrical, 
a little longer than the prothorax, densely, rugosely punctate, not carinate; joint 2 of the funiculus 
nearly three times as long as 1. Prothorax broader than long, narrowed and constricted in front and. 
narrowed behind, the sides rounded at the middle; the surface densely, rugosely punctate, the intervening 
ruge here and there transversely confluent. Elytra ovate, convex, at the middle about one-half wider 
than the prothorax, seriate-punctate, the interstices 2-6 each with a scattered series of moderately 
prominent oblong setigerous tubercles, those on 2 and 3 larger and more conspicuous than the rest. 
Legs very stout, the femora coarsely, rugosely punctate. 
Length 73, breadth 4 millim. (¢-) 
Hab. Guaremana, San Juan in Vera Paz (Champion). 
One specimen, from the vicinity of the Polochic Valley. Very like A. obovatus, 
from Costa Rica and Chiriqui, but larger and more robust, the prothorax transverse, 
relatively broader, and with the ruge transversely confluent, the elytral elevations 
less prominent, especially towards the sides, the tibie straighter. 
14. Anchonus nodipennis, sp.n. (Tab. V. figg. 18, 184, ¢.) 
Obovate, convex, black, the funiculus and tarsi obscurely rufescent, thickly clothed with an earthy incrustation ; 
the sete short, fine, and scattered, but coarser, longer, and clustered together on the elevated portions of 
the surface, forming eight fascicles on the prothorax. Rostrum stout, cylindrical, feebly curved, coarsely, 
seriately punctate. Prothorax transverse, somewhat flattened on the disc, dilated at the sides a little 
before the middle, gradually narrowing thence to the base and abruptly constricted and narrowed in 
front; the surface very closely, coarsely punctate, with the narrow raised interspaces here and there 
shining and granulate, distinctly binodose at the apex and on each side before the middle, and less
