a new subfamily of Scolytide. 429 
abdomine brevius, utrinque ante coxas pro receptione femorum 
posticorum excavatum. Abdomen segmentis longitudine sub- 
sequalibus. 
Mas. Capite transverso, fronte valde deplanata et excavata; 
femoribus anticis tibiisque subtilioribus, his obsolete tuberculatis ; 
elytris ad apicem spinulis vel tuberculis armatis. 
Fem. Capite globoso; in pronoto medio poro magno ; 
femoribus anticis et tibiis fortiter dilatatis, his valde scabrose 
porcatis. 
Of robust cylindrical form, not elongate, and of moderate size. 
Head visible from above, large and globose in the females; in the 
males the whole front is depressed and excavate, and the gular 
region is flattened to afford a hollow for the reception of the 
antenne, so that the head viewed from the side appears rostrate. 
Eyes oblong or oblong-oval, not very convex, narrower and flatter 
in the females, without a trace of anterior emargination. Antenne 
with six-jointed funiculus, variable in length and shape in the 
males, in the females with very short straight scape and funiculus, 
the latter not geniculate, with the basal joint strongly capitate, 
mushroom-shaped and not cupulate, the rest very transverse. 
Club large, flat and solid, impressed with close circular or irregular 
fover, the narrow interstices between which give it a reticulate or 
honeycombed appearance; these large fover show no trace whatever 
of hair-follicles, but two irregular vittz crossing the club, which 
perhaps take the place of the obliterated sutures, are covered with 
minute crowded pits, which, under high magnification (1-12th 
oil-imm. obj.), show papillz projecting from them; the rest of the 
club is hairy, the hair-pits being situated on the borders between 
the fove, and it may be ciliated. Labrum* connate, only distinct 
on buccal surface. Epistoma slightly produced in the males in 
front of antennx, covering the greater part of the mandibles. 
These are larger and prominent in the females, but present no 
special characters. Maxilla with a strongly chitinised cardo, its 
mala quadrate, with the outer apical angle shortly produced in the 
males, and hairy; inner edge straight in that sex, dilated at base 
and sinuate in females, its apex short, rounded, and closely set with 
fine faleate setiform spines, the rest of edge with a row of similar 
nearly straight spines. Maxillary palpi short, triarticulate, with a 
well-marked palpiger simulating a fourth joint, joints cylindrical, 
decreasing in width, first oblique, slightly transverse, second very 
short, third longer than broad, with obscure longitudinal striation. 
* My description of the mouth-parts is based on those of the 
Japanese species alone.
