3. Priotoma brevis. 
Breviter orbicularis, subglobosa, nigra, nitidula, parce brevissime pilosa ; elytris creberrime confertim punctato- 
striatis, striis duabus submarginalibus subintegris, tertia antice abbreviata; antennis pedibusque fuscis. 
Long. 14 millim. 
Hab. Panama, Bugaba, David (Champion). 
About as large as P. contracta, and equal to the specimens of middle size of that 
species, but more convex, and at once to be distinguished by the punctuation of the 
elytra, which in this species is composed of series of large distinct points with fine striz 
between about every third row of punctures; the points, though very thickly distri- 
buted, are not confluent, and there is generally room for other punctures of the same 
size between each ; the interstices are smooth, and smaller points are here and there 
interspersed. The head and thorax are also thickly punctured. The antenne are 
apparently eight-jointed; the funiculus is very short, and may perhaps be composed 
really of four joints, it being to me uncertain whether what appears to be a very short 
joint immediately before the first club-joint does not in fact form its base or stalk; 
the club is well developed ; the first joint is triangular, almost equilaterally, but its 
_ inner angle is rounded off, the second triangular, but not so wide, the last oblong and 
rather narrow. ‘The antenne and legs are dark fuscous-red. The whole body is black, 
but with a very faintly bluish tinge. 
Two specimens are all I can assign to this species. 
4. Priotoma tenuistriata. 
Breviter oblonga, valde convexa, nigra, subtus rufa, nitidula, densius setosa; capite et prothorace subtomentosis ; 
elytris striis tenuibus striatis, creberrime confertim punctatis, striis duabus submarginalibus subintegris 
valde impressis ; antennis, pedibus corporeque infra rufis. Long. 2 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui 4000 to 6000 feet (Champion). 
Very distinct from either of the species yet described. The body, though strongly 
convex, is more oblong; the punctuation is so fine and dense as not to be resolved 
except under the microscope, the strize are, however, distinct enough, although fine ; 
the setose pubescence is denser than in the two preceding species. The antenne are
