670 STAPHYLINIDZA. 
‘with two discoidal punctate impressions, an external lateral impression, and a not very 
definite transverse basal sulcus placed immediately in front of the basal margin. Elytra 
scarcely so long as the thorax, with two very closely placed series of large punctures, 
and on the deflexed lateral margin a patch of two or three punctures about the 
middle. 
Three examples from Guatemala, one from the State of Panama. 
Readily distinguished from its allies by the additional punctures on the outside of 
the elytra. | 
4, Megalops morosus. 
Niger, nitidissimus, elytris maculis humeralibus et suturalibus testaceis ; antennis pedibusque flavis ; prothorace 
minus grosse sulcato et punctato; elytris seriebus duabus brevissimis punctorum, 
Long. 4 millim. 
Hab. GvuatemaLa, Zapote, Cahabon (Champion); Panama, Volcan de Chiriqui 2000 
to 4000 feet (Champion). 
Head with numerous punctures on the space between the eyes. ‘Thorax with punc- 
tured grooves, as in MU. cruciger, but the grooves are not so broad or deep, and are 
interrupted on the middle. Elytra about as long as the thorax; each with a yellow 
spot on the shoulder, and another similarly coloured spot on the suture at the apex; 
and with two very short series of punctures, two or three punctures only in each series. 
Two examples. 
This species may be distinguished from the varieties of WZ. cruciger with small yellow 
markings by the yellow spot at the shoulder. Two examples from Guatemala and a 
like number from the State of Panama. 
5. Megalops armatus. 
Niger, nitidus, elytro singulo fascia curvata testacea ; antennis pedibusque flavis; elytris inzequalibus, seriebus 
duabus brevibus punctorum impressorum. 
Long. 4 millim. 
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 
Head with coarse punctures on the space between the eyes. Thorax with four 
punctured grooves, the two inner ones interrupted in the middle. Llytra longer than 
the thorax, each with a curved yellow mark extending from near the scutellum to 
the middle of the outer margin, and with two deep grooves formed by nearly united 
punctures, and with the space between these and the suture at the base a little 
elevated. Male with the terminal joint of the antenna elongate and setose, and the 
penultimate ventral segment armed with a long spine projecting backwards. ‘Two 
examples,
