5716 STAPHYLINIDZA. 
I can gather, is somewhat of a Lathrobioid type, and as the condition of the pieces of 
the prosternum cannot be ascertained, this may prove to be an erroneous conclusion. 
The two unique examples are in a decayed state, and the under surface is much covered 
with dirt, which, owing to the fragile condition of the specimens, cannot be thoroughly 
removed. 
1. Eusclerus rugifrons. (Tab. XIV. fig. 25.) 
Niger, opacus, capite prothoraceque vix subznescentibus, antennis, pedibus elytrorumque apice testaceis ; capite 
suborbiculari, dense rugoso-punctato, punctatura anterius grossiore. 
Long. 33 millim. 
Hab. GuatEMa.a, near the city (Champion). 
Antenne short, a little thickened outwardly ; third joint slender, much more so than 
the first and second. The punctuation of the head is coarse, rugose, and irregular, 
coarser in front, more indistinct behind, the eyes occupy nearly the entire length of the 
sides. Thorax narrower than the elytra, subquadrate, very densely punctate, the 
punctuation fine and granular, with a narrow smooth line on the basal portion. Elytra 
longer than the thorax, blackish, with the hind margin yellow, finely, extremely densely, 
subrugosely punctate, dull. The unique example is probably a female. 
2. Eusclerus sordidus. 
Sat latus, posterius attenuatus, fuscus, capite, prothorace elytrisque sordide ferrugineis, antennis pedibusque 
flavis; omnino densissime punctatus, opacus, prothorace in medio linea laevigata. 
Long. 3 millim. 
Hab. GuaTEMALA, Cubilguitz 1000 feet (Champion). 
Antenne small, reaching but little beyond the back of the head, entirely yellow. 
Head large, subcircular; eyes very large, convex ; surface excessively densely, finely 
rugose-punctate, quite dull. Thorax transversely subquadrate, a little narrowed behind. 
densely covered with aminute granular punctuation, with a distinct though narrow smooth 
line along the middle. Elytra rather short, but longer than the thorax, excessively 
densely, minutely subrugose-punctate, dull, infuscate-ferruginous. Hind body above 
black. Legs short, yellow. The male has a small emargination on the middle of the 
hind margin of the last ventral segment. 
STILOCHARIS. 
Caput elongatum. Labrum minute bidenticulatum. Caput collo angusto. Prothorax elongatus. Tarsi 
anteriores tenues ; posteriores sat elongati, articulo basali quam secundus conspicue longiore. 
This is one of several genera that connect Medon very closely with Stilicus. Stilocharis 
is near Medon, but differs by possessing a considerably narrower neck and a greater 
development of the anterior part of the prosternum. The left mandible is tri-, the
