708 STAPHYLINIDA. 
Antenne of nearly equal thickness throughout; third joint a little shorter than the 
second. Head small, not visibly sculptured; eyes not prominent. Thorax transverse, 
nearly truncate (very feebly bisinuate) in front ; the sides slightly, the base very strongly, 
curved; the surface without impressions and not visibly sculptured. Elytra much 
longer than the thorax. Hind body with very fine punctuation and pubescence, the 
latter, however, more distinct than on the anterior parts; on the terminal two segments 
the punctuation and pubescence are very obsolete. 
Group PHL@OCHARINA. 
This group cannot very well be defined at present; the chief reason for retaining it 
is that the few genera it comprises cannot be satisfactorily placed in the other groups. 
of “ Oxyteline.” 
ECBLETUS. 
Corpus glabrum, depressum, abdomine parce pubescente. Tarsi quinque-articulati, posteriores elongati. Palpi 
maxillares articulo ultimo breviter conico. Antenne undecim-articulate, filiformes. 
The insect for which this genus is established is a peculiar one, having the appear- 
ance of an Omalium though really allied to Olistherus and Phiwocharis. The mandibles 
are short, thick, and curvate and acuminate at the apex. The maxillary palpi are short 
and thick; the terminal joint as broad at the base as the penultimate joint, thence 
gradually narrowed to the apex. The anterior coxe are oblique, moderately exserted, 
and extend nearly to the front angles of the prosternum; the side-piece of the pro- 
thorax is rather small, and only slightly enlarged behind the coxa, though distinctly 
broader there than it is nearer to the front. The middle coxe are contiguous; the 
hind coxe transverse, their interior lamine rather small; the hind trochanters small. 
Tarsi 5-jointed; the basal joints rather stout, those of the front pair slightly dilated 
in the male; posterior pair with the first joint distinctly longer than the second, the 
second, third, and fourth joints subequal in length, and the terminal joint nearly as 
long as the preceding four joints together.

Long. 3} millim. 
Hab. Panama, San Miguel in the Pearl Islands (Champion). 
Antenne rather stout; second joint stout, longer than the third; joints 4-8 differing 
little from one another and neither of them quite so long as broad, 9 and 10 rather 
longer, the terminal joint short; no elevations over the points of insertion. Eyes 
rather small, very finely faceted. Thorax strongly transverse, truncate in front, slightly 
curved at the sides; even, black, shining, not visibly punctate. Scutellum scarcely
