Tthynchophorous Coleoptera of Japan. 5G 
suturis rectis notata, pilosa. Prothorax subdepressus, lateribus 
determinatis, non tamen marginatis, basi immarginata. Wlytra ad 
basim singulatim convexa, thoracem superantia, Cox antice 
magn globose, a processu prosterni angusto separate. Pedes 
longi, tibiis subcompressis, leviter dilatatis, ad apicem oblique 
truncatis, margine exteriore inermi, ‘T'arsi articulo lo brevi, 2o 
paullo longiore incrassato, 30 brevi, subtus producto et profunde 
emarginato, 40 minimo, So magno ceteris conjunctim acquali, 
flead shortly rostrate, the sides of the rostrum carinate, differing 
according to sex in the single species. Eyes divided, their seg- 
ments distant, placed above and below the base of the rostrum. 
Antennge inserted below the rostral carina between the lower half 
of the eye and the base of the mandible, short, the club nearly 
equal in length to scape and funiculus together. Maxilla with 
outer border rounded, inner edge convex and narrowly produced at 
tip, set with straight flat spines. Submentum produced into an 
angle at either side and broadly emarginate between, witha second 
emargination in middle at base of mentum, which is nearly twice 
as long as broad, narrow at base and becoming dilated to middle 
with sides, thence parallel ; labial palpi long, with joint 1 as long as 
broad, 2 transverse, 3 longer than broad. Prothorax flattened 
above, its sides strongly inflexed to anterior cox, forming an 
angle with pronotum which is not sharp or margined. Anterior 
cox not situated near front border of prosternum, very large, 
prominent and globose, separated by a narrow process ; meso- 
sternum not strongly depressed, middle and posterior cox 
prominent, remote ; metasternum rather short with wide parallel 
episterna, First two abdominal segments little longer than two 
following, which are together equal to fifth, Legs long, tibime quite 
simple, flattened, slightly curved, obliquely excised at apex, with 
inner angle shortly spinose; fourth tarsal joint inserted near base 
of third, which is produced underneath into a long split lobe, but 
not laterally widened. 
The one species of this genus has, at least in the male, 
more the appearance of a Curculionid or an Anthribid, 
than a Scolytid, owing to the prominent rostrum, the 
general shape of its body, the vestiture, and the unarmed 
tibie. It is, however, a true Scolytid, and either one 
of the Hylesini, or not remote from them. I know, 
however, of no described genus with which it is 
closely allied.
