258 STAPHYLINIDZ. 
8. Gyrophena flavipes. 
Nigra, elytris nigro-fuscis, antennis fusco-testaceis, basi pedibusque testaceis, nitidissima, fere impunctata ; 
antennis articulis 5°-10™ transversim quadratis ; prothorace fortiter transverso. 
Long. 13 millim. 
Hab. Mexico, Cordova (Sallé). 
Antenne rather short and stout; terminal joint but little longer than the tenth. 
Thorax very strongly transverse, about twice as broad as long, almost without punctua- 
tion, but with two very minute punctures some distance in front of the base. Elytra 
very shining, not quite so black as the thorax, the shoulders scarcely paler; finely and 
extremely sparingly punctate. 
In the male there are some granules on the sutural portion of the elytra, and the 
third and fourth joints of the antennz are excessively short; the dorsal plate of the 
seventh segment of the hind body has on each side a fine incurved spine, and, between 
these, is angularly prominent in a tuberculiform manner. ‘The female has the third 
joint of the antenne not quite so short. 
Only a single pair is before me; and I have not succeeded in getting a very definite 
sight of the male structural characters. 
9. Gyrophena granulata. 
Subconvexa, nitidula, picea, abdomine rufo, elytris sordide testaceis extrorsum late fuscis, antennarum basi 
pedibusque testaceis; antennarum articulis 3° 4°que brevibus, 5°-10™ leviter transversis ; elytris crebre 
subeequaliter granulatis. 
Long. 2 millim., 
Hab. Panama, Bugaba (Champion). 
Antenne rather short and stout; the first four joints yellow, the rest infuscate ; 
terminal joint short; head without punctuation. ‘Thorax very strongly transverse, 
on the disk with four small punctures placed quadrately, the anterior pair very minute. 
Elytra rather longer than the thorax, bearing numerous fine granules over the whole 
surface. Hind body convex, red, with the fifth segment darker, not very shining, but 
only very obscurely punctate and pubescent. 
In the male the granules on the elytra are rougher than in the female, and the dorsal 
plate of the seventh segment of the hind body terminates on each side in an elongate 
rather slender spine, and between these spines forms a prominent angle, which, however, 
does not project so far back as the apex of the lateral spines. The female has in the 
middle of the hind margin of the corresponding plate two minute slender acuminate 
teeth, and on each side a rather longer, slender, curved spine. 
Five specimens of this species, only one of them a female, have been found. It is 
allied to the Amazonian G. sparsa. 
10. Gyrophena brevidens. 
Vix depressa, nitidula, fusca, antennis pedibus elytrisque testaceis, his ad angulos externos infuscatis ; antennis
