548 | STAPHYLINIDA. 
20. Scopzus delicatulus. 
Haud depressus, politus, nitidus, rufo-piceus ; pedibus pallide flavis; elytris nigris, angulo apicali externo minute 
flavo-guttato ; antennis testaceis; abdomine dimidio apicali nigro. , 
Long. 3 millim. 
Hab. GuatEMALA, El Jicaro (Champion); Panama, San Miguel in the Pearl Islands 
(Champion). 
This insect is very similar to S. apicipennis, but is smaller, and has the head and thorax 
less elongate, and the apical pale spot of the elytra more minute. In some examples 
the legs are entirely pallid yellow, in others the femora are a little infuscate at the 
extremity. 
The unique example from Guatemala is a variety of rather paler colour. The eight 
examples from the State of Panama exhibit but little variation. | 
EUSCOPARUS. 
Labrum longius bispinosum, medio fere ad basin exciso. Mandibule sat elongate, tantum minute 
denticulate, quasi serrate. Caput collo angustissimo. Tarsi breves, robusti, articulo ultimo presertim 
lato. 
These insects are allied to Scopus, but are of rather broader and heavier build; and 
the very long teeth in the middle of the labrum, in conjunction with the peculiar minute 
teeth of the mandibles, seem to me to render it necessary to treat them as a genus distinct 
from Scopeus; the latter character is not to be found in any of the allied genera so far 
as I have been able to observe. 
Same habits as Scopewus (Champion). 
1. Euscopzus crassitarsis. | 
Haud depressus, robustus, brunneus, pedibus testaceis; omnium subtilissime vix perspicue punctulatus; tarsis 
latis. 
Long. 44 millim. 
Hab. GuatTEMALA, near the city (Champion). 
Antenne rather slender, the penultimate joint as long as broad. Head broad, convex, 
slightly narrowed in front, the hind angles much rounded ; surface excessively minutely | 
and indistinctly punctate and pubescent, not shining. Thorax broad, but rather longer 
than wide, subovate, much narrowed in front, almost impunctate. Elytra longer than — 
the thorax, finely and not densely punctate, shining. Hind body broad, narrower 
towards the base. Front tarsi thick; terminal joint of all the tarsi very stout. The 
male has a large and deep emargination of the last ventral plate. One example. 
2. Euscopzeus gracilicornis. (Tab. XIV. fig. 9.) 
Haud depressus, brunneus, pedibus pallide flavis ; omnium subtilissime vix perspicue punctulatus ; labro longius 
bispinoso. 
Long. 44 millim.
