ANCHONUS. 83 
Hab. Costa Rica, San José (Biolley), Volcan de Irazu (Rogers). 
Two specimens, the one from San José being larger and more elongate than the 
other, with the prothorax carinate down the middle, the one from Irazu with the sete 
on the prothorax tending to form fascicles on the disc. Very like the Guatemalan. 
A. cirratus, but with the prothorax regularly rounded at the sides, and feebly constricted 
in front, the elytra widest a little below the base and more attenuate posteriorly. 
In general facies it resembles Cestophorus granulicollis, Faust, from Venezuela, but 
has a shorter scape to the antenne *,

Hab. Mexico}. 
This species, the type of which is figured, is not represented in our collection. It 
somewhat resembles A. elongatus, but is much smaller and shorter, and not so coarsely 
tuberculate ; the dorsal interstices of the elytra are interruptedly carinate and minutely 
granulate, the third and fifth + more raised at the base. The elytral elevations are less 
conspicuous, and more cariniform, than in any of the Mexican species here described. 
31. Anchonus crinitus, sp. n. (Tab. VI. figg. 4, 4a, 9.) 
Obovate, black, the antennx and tarsi partly rufescent, thickly coated with an earthy incrustation ; the sete 
coarse, erect, moderately long, and abundant. Rostrum stout, curved, slightly thickened towards the 
base, and there feebly constricted, coarsely seriate-punctate. Prothorax transverse, rather convex, with 
the sides much dilated a little before the middle, obliquely narrowing thence to the base, and strongly 
constricted and narrowed in front; the surface coarsely, closely varioloso-punctate, with the very narrow 
raised sinuous interspaces shining and tending to form an irregular transverse ridge near the anterior 
margin, the disc with an abbreviated shining median carina. Elytra convex, short-ovate ; seriate-punctate, 
each interstice with an interrupted row of small, smooth, somewhat closely placed, shining tubercles. 
Length 43, breadth 2,1, millim. ( 9.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. Not very closely allied to any of the other species here described, 
and recognizable by the hexagonal, varioloso-punctate prothorax, the interrupted series 
of small, shining tubercles on each of the dorsal interstices of the elytra, and the coarse, 
erect setosity of the surface. 
82. Anchonus alternans, sp.n. (Tab. VI. figg. 5, 5a, 2.) 
Ovate, moderately convex, black, the apex of the rostrum, the legs, and antenne obscurely rufescent ; the sete 
erect, long on the elytra, and short elsewhere. Rostrum stout, cylindrical, curved, slightly longer than 
the prothorax, feebly constricted at the base, rather coarsely seriato-punctate, not carinate. Prothorax 
transverse, somewhat arcuately dilated at the middle, strongly and abruptly constricted before the apex, and
