PINOPHILUS. 623 
shorter antenne; the head and anterior parts of the thorax more shining; this latter 
is about as long as broad, scarcely at all narrowed behind, transversely convex, the 
coarse punctuation shallow and not at all dense, and the smooth space on either side 
near the front very distinct and polished. The cedeagus is shorter and not so slender 
as it is in P. albipes, and its lateral corneous wings do not appear as detached 
prominences. 
7. Pinophilus guatemalenus. 
Niger, opacus ; palpis, pedibus antennisque pallide flavis, his articulis extrorsum fuscescentibus ; capite prothora- 
ceque punctatis pretereaque minute punctulatis ; elytris prothoracis longitudine, densissime, fortiter, rugose 
punctatis. 
Long. 15 millim. 
Hab. GuateMALa, Torola, Paraiso, San Gerénimo, Balheu, San Joaquin (Champion). 
Externally this insect is excessively similar to P. albipes, but the sculpture is rather 
coarser and denser; the cedeagus, however, shows distinctions indicating that this may 
probably be a different species ; the median style is shorter and broader, and instead of 
being gradually narrowed from the base to the apex, it is parallel-sided for three fourths 
of the length, and thence more abruptly narrowed; the short corneous lateral wing 
is shorter and broader than in P. albipes. There is also an external sexual distinction, 
inasmuch as the last ventral plate is much shorter than in P. aldzpes. 
We have received only six examples of this species. 
8. Pinophilus iners. : 
Angustulus, subopacus, niger ; elytris rufis, densissime fortiter punctatis ; antennis, palpis pedibusque flavis ; 
prothorace sat crebre et fortiter punctato, subopaco. 
Long. 12-13 millim. 
Hab. Panama, Tolé, San Feliz (Champion). 
Head picescent in front, the mandibles red. Thorax quite as long as broad, with 
rather close but shallow coarse punctures, and with a dense, interstitial, minute 
sculpture rendering the surface dull. LElytra no longer than the thorax, with very 
dense coarse punctuation, dark red. Hind body black, with one or two of the terminal 
segments a little rufescent behind. 
The external distinctions of the sexes are not very conspicuous, but in the male the 
last ventral plate is more shining and impunctate in the middle behind, the hind margin 
of the plate is more truncate, and the ventral valve of the armature has the apical 
portion strongly laterally compressed and acuminate, but scarcely recurved. 
This is another species closely allied to P. albipes. Only one pair was found at Tolé ; 
a female specimen of a variety from San Feliz, of broader form and with feebly rufescent, 
rather larger elytra, may not be the same species.
