9. Megalops cognatus. 
Niger, nitidus, elytro singulo macula magna externa testacea ; antennis pedibusque flavis ; capite prothoraceque 
haud numerose punctatis, hoc sulcato ; elytris pone humeros punctis quatuor impressis. 
Long. 43 millim. 
Hab. Panama, Volcan de Chiriqui between 2000 and 4000 feet (Champion). 
This species appears to be very close to M. integer, but the yellow spot is much more 
separated from the suture, and there are four punctures on each wing-case. We have 
only received one example; and I do not know which sex it represents. The terminal 
joint of the antenne is similar in shape to that of M/. integer, but it is much smaller ; 
on the other hand it is much larger than in the female sex of M. cruciger and its allies. 
10. Megalops elegans, (Tab. XVII. fig. 20.) 
Niger, nitidus, elytris abdomineque testaceo-variegatis ; antennis pedibusque flavis; prothorace elytrisque 
ineequalibus, his multipunctatis. 
Long. 5 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne short. Head with very numerous punctures on the space between the 
eyes. Thorax without grooves, but with very many punctures, and with smooth, 
shining, elevated spaces. Elytra short and very broad, testaceous, marked with black 
about the scutellum and at the four angles, with an elevated space near the suture 
towards the base, and with numerous coarse punctures placed in two series, and a large 
external patch. Hind body with pallid marks on the penultimate segment and on the 
margins of the other segments. 
A single female. 
11. Megalops preditus. (Tab. XVII. fig. 21.) 
Niger, nitidus, elytro singulo macula externa rufo-testacea; antennis pedibusque flavis, illis extrorsum fuscis ; 
oculis majoribus; prothorace transversim sulcato ; elytro singulo striola curvata impressa. 
Long. 43 millim. 
Hab. Panama, Volcan de Chiriqui between 2500 and 6000 feet (Champion). 
Head with very large eyes, moderately numerously punctate. ‘Thorax with three 
broad and deep furrows bearing punctures, and the base in front of the hind margin 
depressed, the two furrows near the disc interrupted for a short space only; there are 
no punctures except in the grooves. Elytra broad, shining, each with a deep, impressed, 
curved striola behind the shoulders. Legs elongate. 
Two examples; they have the terminal joint of the antenna small, and are probably 
females. 
This is a very distinct species, resembling in its large eyes, long legs, and the striole 
on the wing-cases the species of the next group, from which, however, it remains quite 
distinct by the structure of the tarsi.
