546 STAPHYLINID. 
Hab. Guaremata, Rio Naranjo 450 feet (Champion). 
Antenne a little thickened externally ; second and third joints equal, the penultimate 
joints transverse. Head oblong, the vertex a little emarginate ; surface extremely finely 
punctate, only slightly shining. Thorax suboblong, minutely punctate, more shining 
than the head. Elytra excessively densely punctate, so as to be quite dull; black, the 
basal portion with a griseous pubescence, the hind margin rather broadly yellow. | 
Femora blackish, the tibie and tarsi pallid yellow. The unique example of this very 
distinct species is a male, and has a deep excision of the terminal ventral segment, a- 
very slight excision of the preceding segment, and on the three more basal segments a 
transverse shining space, depressed, but with the front margin somewhat carinate. 
_ § 4. Larsi longer ; surface of the body, including the elytra, polished. 
16. Scopzus politus. (Tab. XIV. fig. 8.) 
Elongatus, haud depressus, politus, nitidus, fere impunctatus, rufo-testaceus ; elytris fusco-nigris, abdomine apice 
nigricante, pedibus pallide flavis; antennis articulis quarto ad sextum interdum infuscatis. 
Long. 33 millim. 
Hab. Guatemata (Sallé), near the city, San Gerdnimo, El Jicaro, Rio Naranjo 
(Champion). 
Antenne not quite so long as the head and thorax, a little thickened externally, the 
third joint nearly as long as the second, the penultimate joint not quite so long as broad. 
Head suboval, convex, the eyes prominent, a little narrowed behind, the hind angles 
rounded, the vertex not emarginate; surface impunctate, with a scanty, not short, 
depressed pubescence. Thorax considerably longer than broad, a little narrowed behind, 
and still more strongly in front, shining and impunctate. Elytra scarcely longer than 
the thorax, blackish, obscurely rufescent about the suture. Hind body very finely 
punctate, the terminal segments blackish. Legs clear pale yellow. The male has a 
broad rather shallow excision of the hind margin of the last ventral plate. 
The small series of this species exhibits some variation in the colour of the elytra, 
the fuscous coloration being sometimes so much reduced that these parts are nearly 
entirely pale with an infuscation near the apical angle; this is especially the case in 
the examples from the Rio Naranjo. One or two of the specimens are intermediate. 
17. Scopeus discoidalis. 
Haud depressus, politus, nitidus, fere impunctatus, testaceus; elytris oblique nigricantibus, sutura, apice basique 
dilutioribus, abdominis apice nigricante. 
Long. 23 millim. 
Hab. Guatemaua, San Gerdnimo (Champion); Nicaracua, Chinandega (Sai/é). 
Antenne rather short, thickened externally, the penultimate joint strongly transverse. 
Thorax oblong oval, not elongate. Elytra very sparingly punctate.
