586 STAPHYLINIDA. 
12. Stilicus dissimilis. 
Niger, subopacus, pedibus fusco-testaceis, femoribus ex parte majore testaceis ; capite prothoraceque densissime 
punctatis, hoc medio subtiliter canaliculato; elytris crebrius subtiliter punctatis, subnitidis, angulo apicali 
externo flavescente; tibiis anterioribus subincrassatis. 
Long. 4 millim. 
Hab. GuatEMALA, Quiche Mountains 7000 to 9000 feet (Champion). 
Antenne short, much thickened externally, the penultimate joints strongly transverse. 
Labrum with two very prominent teeth in the middle. Head elongate, densely rugose- 
punctate. Thorax broad and short, very densely rugose-punctate. Elytra much longer 
than the thorax. Front tibie thicker than usual, rounded externally. Underside of 
the head very densely and coarsely punctate. 
This very distinct species is unique ; the example obtained being a female. 
SUNIOCHARIS. 
Corpus angustulum ; facies quasi Suntorum. Caput posterius truncatum, collo sat angusto. Tarsi omnes 
tenuiores ; anteriores nullo modo dilatati, posteriores articulo basali quam secundus fere duplo longiore. 
This genus is not only remarkable from its resemblance to Sunius, but has really the 
tarsi constructed to a certain extent like those of that genus, though owing to their great 
tenuity this is very difficult to perceive ; the terminal joint is, however, inserted above 
the fourth joint very near the base of the third; as the fourth joint is thus placed 
underneath the terminal one, and is not wider than it, the foot appears to be only 
4-jointed. The mandibles are short, acutely tridentate; the labrum is large, very 
indistinctly bidenticulate in the middle. The neck is not so narrow as in Lithocharis ; 
the thorax has the front margin only gently curved so that the form is quadrangular. 
The prosternum is large, the prosternal process is elongate, and the side pieces large. 
The front femora are rather dilated. The basal ventral segment is carinate at the base. 
1. Suniocharis modesta. (Tab. XV. fig. 9.) 
Angustula, ferruginea, elytris dilutioribus, abdomine obscuriore, pedibus flavis; capite prothoraceque opacis, 
fere impunctatis ; elytris dense subtilissimeque punctatis. 
Long. 4 millim. 
Hab. Mexico, Cordova (Sallé), Mirador (Hége); Guatemaa, Mirandilla (Champion) ; 
Nicaragua, Chinandega, Managua (Sal/é) ; Panama, David, Bugaba, San Miguel in the 
Pearl Islands (Champion). 
Antenne small and slender; ninth and tenth joints distinctly longer than those 
preceding, the tenth a little longer than broad, the terminal joint still longer. Head 
nearly as broad as the thorax, straight at the sides and quite truncate behind, exces- 
sively obsoletely punctured. Thorax about as long as broad, very slightly narrowed 
behind, the sides a little curved, impunctate, but quite dull, with the marginal sete black
