Rhynchophorous Coleoptera of Japan. 87 
scales. Legs fusco-piceous with tarsi lighter, outer border of 
middle tibiz distinctly serrate. 
This insect is very like Hypothenemus tristis and 
peritus, but is more elongate; the base of the thorax 
and the elytra are differently sculptured, and the struc- 
ture of the antennz and legs will at once separate it 
without comparison. 
PityopntuHorvs, Kichh. 
But one species has yet been found in Japan. It is 
likely that there are others as, in addition to the Euro- 
pean species, there are several from both N. and 8. 
America. 
Pityophthorus jucundus, sp. n. 
Elongatus, oblongus, nitidus, fere glaber, niger vel fusco- 
testaceus ; prothorace antice subconstricto, post medium utrinque 
impresso, anterius exasperato, posterius fortiter punctato, linea 
media subelevata laevi; elytris cylindricis, haud acuminatis, 
regulariter punctato-striatis, striis non impressis, interstitiis fere 
planis hic illinc subrugulosis, apice impresso-retuso, striis obsoletis, 
lateribus elevatis et sutura versus apicem tuberculis setigeris raris 
ornatis. Long. 1°6 mm. 
Fem. Fronte media villosa. 
Four specimens, near Nagasaki. 
Head black, finely reticulate, front strongly punctured, with a 
circular patch of villous pubescence in female. Antenne fusco- 
testaceous, their club ovate, tri-articulate with slightly curved 
sutures. Prothorax with base finely margined, truncate, basal 
angles obtuse, sides behind nearly straight, rounded in front and 
sinuate before apex, which is somewhat obtusely rounded, and 
feebly crenate, the apical constriction much slighter than in 
P. lichtensteini, Ratz; surface depressed on either side of a median 
smooth elevated line, reaching to the middle of the prothorax, 
with very short pubescence at sides and apex, its anterior half 
asperate, posterior half with rather strong subrugose punctures 
becoming weaker on sides, Elytra rather narrower at base than 
prothorax, and nearly twice as long, sides straight to middle then 
feebly rounded, apex obtusely rounded, not acuminate but with 
suture slightly prominent ; glabrous except at apex, with regular 
lines of strong punctures, not impressed, interstices impunctate and 
flat, feebly rugose here and there, apex nearly vertically declivous,
