624 STAPHYLINID. 
9. Pinophilus lineaticollis. 
Angustulus, piceus; antennis, palpis pedibusque flavis; elytris densissime fortiter punctatis, prothorace fere 
brevioribus ; hoc crebrius fortiterque punctato, subopaco, medio linea angustula nitida, 
Long. 13 millim, 
Hab. Panama, Pefia Blanca 3000 to 4000 feet (Champion). 
This may possibly prove to be a variety in an immature state of P. iners, but I think 
it more probably distinct, though the male characters externally appear almost 
identical. P. lineaticollis, however, is more uniform in colour, the elytra being but 
little more rufescent than the rest of the surface, and there is a distinct shining line 
along the middle of the thorax. Unique. 
10. Pinophilus fragilicornis. 
Niger, subdepressus ; capite prothoraceque picescentibus, omnino opacis, hoc alutaceo et sat crebre subtiliterque 
punctato ; antennis, palpis pedibusque pallide flavis; elytris dense fortiterque punctatis, sat nitidis. 
Long. 11 millim. 
Hab. Panama, Bugaba (Champion). 
This is a very distinct species, distinguished by the regularly alutaceous, very dull 
thorax, which bears also numerous larger but yet fine punctures. The elytra are 
evidently longer than the thorax. ‘The unique example found is a male, and has the 
last ventral plate prolonged behind, and with an angular notch at the extremity. I 
do not detect any spine at the apex of the ventral valve of the armature. 
11. Pinophilus opacicollis. 
Subdepressus, nigricans, opacus ; antennis, palpis pedibusque flavis; prothorace peropaco, subtiliter punctato ; 
elytris densissime punctatis. 
Long. 15 millim. 
Hab. Panama, Pefia Blanca 3000 to 4000 feet (Champion). 
Similar in form to P. albipes, though more depressed, and with a shorter thorax, 
which is less narrowed behind; the thoracic sculpture, however, is very different, the 
surface being alutaceous so as to be quite dull, and the larger punctures, so conspicuous 
in P. albipes, are here small and indistinct. The elytra are obscurely rufescent at the 
base. 
The only example discovered is a female. 
§ 2. Thorax globose, oblong, shining (Pinophilus spurius). 
12. Pinophilus penetrans. (Tab. XVI. fig. 14.) 
Nitidus, niger, laxe pubescens; antennis, palpis pedibusque flavis, elytris sanguineis, abdominis apice late 
rufo; prothorace vix transverso, lateribus rotundatis, basin versus angustatis, fortiter punctato.
