698 STAPHYLINID A. 
2. Trogophleus suffusus. 
Angustus, subdepressus, subnitidus, nigricans ; prothorace piceo, elytris rufis, antennarum basi apiceque cum 
pedibus testaceis ; prothorace dorso bi-impresso ; elytris minus obsolete punctulatis. 
Long. 2? millim. 
Hab. Guatemata, Paso Antonio (Champion). 
Antenne short and stout; third joint smaller than the second, the penultimate 
joint strongly transverse. Head a little narrower than the thorax; eyes small. Thorax 
not very strongly transverse; much rounded at the sides, so that the front angles. 
are quite obtuse; surface visibly punctulate, the disc with two elongate impressions. 
Elytra rather longer than the thorax, rather closely and distinctly punctate, somewhat 
shining. Hind body becoming broader towards the apex. Unique. 
This Zrogophieus has an appearance quite similar to the European species of the 
T. riparius and T. corticinus group; it is not closely allied to any of the others here 
recorded. 
3. Trogophleus planellus. (Tab. XVIII. fig. 16.) 
Sat latus, subdepressus, sat nitidus, nigricans; antennis fusco-testaceis, basi pedibusque testaceis, elytris fulvis ; 
prothorace fortiter transverso, basi minus profunde bi-impressa, angulis anterioribus obtusis; elytris quam. 
prothorax multo longioribus, densius, subtiliter, sed perspicue, punctulatis, sat nitidis. 
Long. 22 millim. 
Hab. Guatemana, Rio Naranjo (Champion); Panama, Bugaba (Champion). 
Antenne slender, thicker externally; penultimate joint about as long as broad. 
Head broad, very short; eyes large. Thorax twice as broad as long, rounded at the 
sides and much narrowed behind, quite truncate in front; anterior angles but little 
deflexed, obtuse ; the two basal impressions short and rather indefinite. Elytra much 
longer than the thorax, finely but quite distinctly punctulate, shining. 
This species is very closely allied to the Cuban 7. aridus, Jacq. Duv., but is con- 
siderably smaller, has shorter antenne, more pallid elytra, and less distinct thoracic 
impressions. It varies in the colour of the elytra, which sometimes are nearly black. 
4. Trogophleus filarius. 
Angustus, haud convexus, dense subtilissimeque punctulatus, subopacus, nigricans ; antennis pedibusque testaceis, 
illis extrorsum magis obscuris; prothorace minus transverso, basin versus angustato, angulis anterioribus. 
rotundatis et fere equali; elytris fulvis. 
Long. 2 millim, 
Hab. Guatemata, San Gerdnimo (Champion). 
Antenne short and rather slender; third joint much smaller than the second, the 
penultimate joint slightly transverse. Head short, deeply bi-impressed. Thorax rather 
broader than long; the front angles rounded, whence the sides are narrowed to the 
base ; the surface very finely punctulate, feebly shining, just visibly bi-impressed at the
