CAMPTODES. 333 
16. Camptodes politus, sp. n. 
Subhemisphericus, supra nigerrimus, nitidior, subtus fusco-testaceus, pectore, abdomine pedibusque quatuor 
posterioribus nigris ; antennis brevibus, testaceis, clava fuscescente ; sparsim punctatus. 
Long. 33 millim. 
Hab. Guatemata, Zapote (Champion). 
We have received only one specimen, a female, of this species, and, though it resembles 
C. morio, it is very distinct therefrom, so that there will be no difficulty in recognizing it. 
The upper surface is remarkably polished, sparingly punctate ; the thorax is yellowish at 
the sides towards the front; the pygidium is sparingly and finely punctate, shining black. 
The prosternal process is small, the prosternum shorter than usual; the mesosternal 
carina is much more slender at the base than it is in C. morio; and the metasternal 
margin may be traced in the middle, though it is there both fine and obsolete. 
17. Camptodes nigriclava, sp. n. (Tab. X. fig. 22, ¢ .) 
Subhemisphericus, nitidus, ferrugineus, antennarum clava nigerrima ; supra sparsim fortiter punctatus. 
Long. 43 millim. 
Hab. Mexico, Tapachula in Chiapas (Hége).—Sourn America, Colombia (coll. 
Sharp). 
This is another species of which we have received only one female example ; though 
very like (except in colour) some of the varieties of C. morio, it is readily distinguish- 
able by the intense black colour of the club of the antenne in complete contrast to the 
rest of the surface; the club is also a little larger than usual. The legs, moreover, are 
all considerably more approximate than they are in C. morio or C. gaumeri. ‘The 
upper surface is very shining, its punctuation rather coarse but distant ; the punctures 
on the pygidium are few and subobsolete. 
18. Camptodes decipiens, sp. n. 
Rotundatus, convexus, ferrugineus, nitidus, parce subobsolete punctatus; stria suturali parum profunda ; 
pygidio nitido, fere levigato. 
Long. 4 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Smaller than C. nigriclava and less distinctly punctured, and, besides, readily distin- 
guished by the more pallid club of the antenne; there are no punctures on the 
pygidium, but its surface is obsoletely aciculate. 
C. decipiens is remarkably similar to C. communis and C. cognatus of the following 
section, but the sutural stria and the lobing of the tarsi are quite those of this group ; 
the margin of the metasternum is present though only slightly raised and inconspicuous. 
Two male specimens.
