POLYLOBUS.—OXYPODA. 159 
finely punctate. Elytra longer than the thorax, of a pale yellow colour, rather closely 
and finely punctate, the hind margin deeply sinuate at the outer angle. Hind body 
convex, much turned upwards, narrowed behind; the segments partly black, partly red ; 
on those at the base the red colour predominates, while at the extremity the reverse is 
the case; closely punctate. Legs clear reddish yellow. 
In the male there is an elongate carina along the middle of the posterior part of 
the sixth dorsal plate of the hind body, and on the following segment a similar but less 
elevated keel. 
Only a single badly preserved individual has been found. 
OXYPODA. 
Oxypoda, Mannerheim, Brachel. p. 69 (1830) ; Erichson, Gen. et Sp. Staph. p. 141. 
The species of this extensive genus reach the number of one hundred and fifty, and 
are chiefly characteristic of the European region; one or two, however, have been 
described from North America, one from Brazil, and several from Chili. Of the species 
here described, O. clavigera is assigned with some doubt to the genus, and another, 
O. palpalis, will no doubt prove to be entitled to generic distinction. 
1. Oxypoda clavigera. 
Minuta, brevior, dense subtilissime punctulata, omnino brevissime inconspicue pubescens, opaca, rufo-testacea, 
antennis, capite abdomineque ante apicem brunneis, antennarum basi pedibusque testaceis; antennis 
brevibus, extrorsum incrassatis, articulis penultimis valde transversis. 
Long. 14 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne short, much thickened outwardly, third joint shorter than the second, fourth 
to tenth each strongly transverse; terminal joint stout, as long as the two preceding 
together. Head broad and short, very finely punctulate; eyes rather small. Thorax 
strongly transverse, very convex transversely, very finely punctate. Elytra short, scarcely 
longer than the thorax, very finely punctate, hind margin almost without sinuation near 
the outer angle. Hind body very densely punctate, fourth and fifth segments infuscate. 
The antenne of this minute insect are very short and stout for an Oxypoda; but I 
believe it to belong to the genus, although the three individuals found are so much 
covered with gum tragacanth that I cannot verify their structural characters. 
2. Oxypoda certata. 
Angustula, posterius acuminata, dense subtilissime punctulata, opaca, testacea, antennis (basi excepta) elytris 
ad angulum exteriorem abdomineque apicem versus fuscescentibus; antennis subgracilibus, articulis 
penultimis leviter transversis. 
Long. 3-37 millim. 
Hab. Guatemata, Cerro Zunil 4000 to 5000 feet (Champion).
