OXYTELUS, 693 
very slight, almost the same as in O. spinifrons, the chief one being that the penultimate 
segment has some fine punctuation on the middle of the hind margin. 
14. Oxytelus latifrons. 
Niger, nitidus; elytris piceis, antennarum basi, mandibulis pedibusque testaceis; prothorace trisulcato, inter- 
stitiis latioribus, parce punctatis; elytris punctatis, vix strigosis. 
Mas clypei medio longius spinoso-producto. 
Long. 43 millim. 
Hab. Panama, Bugaba (Champion). 
Head of the male short and broad; the vertex smooth, not channelled, the middle 
finely strigose ; clypeus polished, and produced into a very long spine in front, the 
oblique channel on each side deep; mandibles very long. Terminal ventral plate 
deeply bisinuate, so that the middle forms a short, broad lobe; hind margin of the 
penultimate segment emarginate in the middle, and obsoletely punctate in front of this. 
Though we have only one male, and it is very close to the three preceding species, it 
will probably be found more easy to separate it, as the intervals between the thoracic 
grooves are rather more flattened and broader. 
15. Oxytelus incilis. 
Piceus, capite nigro, pedibus flavis; clypeo nitido, vertice strigoso-punctato; prothorace profunde trisulcato ; 
elytris brevibus, parce punctatis, vix strigosis. 
Mas clypei medio breviter spinoso-producto. 
Long. 3 millim. 
Hab. GuatEeMaLa, Coatepeque 1300 feet (Champion); Panama, San Miguel in the 
Pearl Islands (Champion). 
This is smaller than either of the foregoing species, and has joints 7-10 of the 
antenne transverse. The head has the vertex strigose, and a short channel in the 
middle; it has no oblique lateral channel. There is very little punctuation on the 
thorax, and the sculpture of the elytra is much effaced. The male can be readily 
distinguished from the female by its head being larger and spinose in front; this sex 
is destitute of any notable abdominal character. 
16. Oxytelus exaratus. 
Niger, sat nitidus; fortiter strigosus; pedibus flavis, mandibulis antennarumque articulo ultimo rufescentibus ; 
prothorace profunde trisulcato. 
Long. 4 millim. 
Hab. Guatemaa, Balheu in Vera Paz 3000 feet (Champion). 
This, though closely allied to the preceding species, is readily distinguished from all 
of them by the dense coarse strigosity of the wing-cases, on which no punctures can be 
detected. We have only one example, which is no doubt a female. The antenne are 
elongate, the basal joints piceous, the penultimate joint quite as long as broad, the
