MEGALOPS. 675 
or black in the middle, the margins in great part, and the apex, red. Under surface 
piceous-red, with the breast red. Male with the terminal joint of the antennez broad 
and not acuminate and considerably larger than in the female. 
Two examples. 
18. Megalops porcatus. 
Nigro-subzneus, nitidissimus ; antennis pedibusque flavis, femoribus sordidis ; capite prothoraceque numerose 
punctatis, hoc haud sulcato ; elytris seriebus duabus punctorum, punctis nonnullis ad suturam et ad mar- 
ginem lateralem adjectis. 
Long. 37 millim. 
Hab. Guatemata, Cerro Zunil 4000 to 5000 feet (Champion). 
The antenne are short, the eyes small. The head and thorax covered with large 
punctures; on the latter there are, however, some small, irregular, shining spaces. 
There are six small distinct foves at the base of each segment of the hind body. 
Of this distinct little insect we have received but one example ; its sex is uncertain, 
the terminal joint of the antenne being of moderate size. 
19. Megalops peploides. (Tab. XVII. fig. 24.) 
Brevis, nigro-piceus, minus nitidus; prothorace omnino densissime, grosse punctato ; elytris sulcatis, 
Long. 24 millim. 
Hab. Panama, Bugaba (Champion). 
Independently of its extraordinary sculpture, this little insect could be recognized by 
its comparatively small eyes and short legs. The antenne are very short; the terminal 
joint sub-globular, the preceding one very strongly transverse. The head is small, its 
width, including the eyes, being much less than that of the elytra; the sides of the 
front are greatly elevated over the insertion of the antenne, and the intervening space 
bears some coarse punctures. ‘The thorax is broad and rather short, denticulate at the 
sides, with coarse punctures so crowded that they are in part confluent. The elytra are 
broad and short, and each bears four or five deep, though irregular, punctate longitudinal 
grooves. The six fovee on the basal segment of the hind body are rather large, 
those on the following segments smaller. Unique. 
§ 2. Tarsi with the fourth joint prolonged as a lobe or style beneath the terminal joint. 
20. Megalops incultus. 
Nigerrimus, nitidus; pedibus antennisque flavis, his extrorsum fuscis; prothorace punctato-sulcato, preterea 
vix punctato; elytris striola curvata impressa. 
Long. 32 millim. 
Hab. Mexico, Teapa (Sallé); Panama, Bugaba (Champion). 
Head with a few punctures only between the eyes, these latter large. Thorax with
