674 STAPHYLINIDA. 
15. Megalops vulneratus. 
Nigerrimus, nitidus ; antennis pedibusque flavis ; capite prothoraceque numerose punctatis, hoc parum profunde 
sulcato ; elytris seriebus duabus punctorum abbreviatis punctisque nonnullis externis adjectis ; oculis haud 
magnis, 
Long. 3} millim. 
Hab. Panama, Caldera in Chiriqui 1200 feet (Champion). 
Head with numerous punctures, which are not so coarse as in most of the other 
species of the genus. Thorax with the anterior channel almost obsolete and not parallel 
with the anterior margin, its situation rendered very definite by the numerous rather 
fine punctures; the second groove more distinct, and likewise very definitely punctate, 
and on the middle angulate behind; just behind the middle on each side is a 
punctate depression, and the disc is occupied by an angular elevation. The punctures 
of the elytral series are large and definite, and there are seven or eight on the outer, 
and five on the inner series; the punctures on the outside are placed in an irregular 
manner, and are five or six in number. 
This species has smaller eyes than any other MJegalops, except the aberrant 
M. peploides ; it will be identified by this character and by the punctures on the thorax 
being less coarse than usual. The unique example is in very bad condition; it isa male 
and has the terminal joint of the antenne large, suboblong, with gently rounded apex. 
16. Megalops obscurus. 
Nigro-piceus, nitidus ; capite prothoraceque nigris, elytrorum basi dilutiore, antennis pedibusque flavis ; capite 
prothoraceque sat numerose punctatis, hoc obsolete sulcato; elytris seriebus duabus abbreviatis punctorum. 
Long. 35 millim. 
Hab. Guatemata, San Isidro 1500 feet (Champion). 
Apparently closely allied to WM. guatemalenus, but I think distinct: independently 
of the more dilute colour (which is perhaps in part due to immaturity) IZ. odscurus is 
rather more slender, and has considerably smaller eyes, and the thoracic sulci are a 
little deeper and more definitely punctate. The unique example is a female; its 
antenne are nearly similar to those of I. guatemalenus. 
17. Megalops basalis. (Tab. XVII. fig. 23.) 
Piceo-rufus, nitidus ; capite superne, pronoto elytrisque ex parte majore nigricantibus, his basi abdomineque 
apice rufis, antennis pedibusque flavis, abdominis lateribus rufo-variegatis ; capite prothoraceque crebrius 
fortiter punctatis, hoc ineequali, haud sulcato ; elytris seriebus punctorum duabus abbreviatis. 
Long. 34 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne short. Head with numerous large punctures ; eyes only moderately large. 
Thorax with the grooves effaced, but their position still indicated, the punctuation on 
the other hand greatly developed. Elytra broadly red at the base. Hind body piceous
