Rhynchophorous Coleoptera of Japan. 113 
wider than prothorax at base and about half as long again, 
humeral angles subrectangular, shoulders narrowly callose, sides 
parallel to behind middle, thence rounded to apex, which is not 
earinate below ; surface cylindrical with slightly impressed rows of 
oblong punctures, interstices narrow with a single row of very fine 
setigerous punctures, about as numerous as those of striz, the 
hairs stronger towards apex, which is strongly but obliquely 
declivous, slightly flattened, and impressed along the suture with 
the punctures of the striz larger, rounded, and shallow ; interstices 
flat with microscopic traces of tuberculation, rather more evident 
on the third interstice. Underside and legs ferruginous, the former 
shining, punctured, and pubescent. 
In the feeble development of any apical armature to 
the elytra, this species differs from any described by 
Kichhoff. Other examples of the same type occur in the 
Oriental and Polynesian regions, e.g., X. obliqwus, Sharp, 
from Hawai.
