124, Mr. Walter F. H. Blandford on the 
prothorax, antenne ferruginous. Prothorax longer than broad, 
subtruncate at base with posterior angles rounded, sides slightly 
rounded, apical angles strongly rounded, apex transverse but 
produced in middle into a strong triangular spine directed forwares 
and upwards, anterior opening of protkorax horizontal, slightly 
produced downwards below spine ; surface convex, with a median 
obtusely pointed elevation, in front of which is a deep triangular 
impression reaching apical spine, its anterior half very finely 
asperate, its posterior half with distinct scattered punctuation. 
Scutellum very small, triangular. Elytra narrower than prothorax 
and one-third longer, separately convex at base with margin 
elevated, humeral prominences obsolete, sides subparallel to apex, 
which is broadly rounded; surface nearly cylindrical, declivous 
and convex at apex, the declivity finely carinate below for a short 
distance, with rows of fine punctures ; interstices flat, subrugose, 
with a single row of remote piliferous punctures, on declivity more 
distinctly and transversely rugose, Ist and 3rd with four or five 
fine tubercles, 2nd with traces of two tubercles on summit only. 
Legs ferruginous, tibize strongly dilated and serrate. 
This insect is the male of a species in Hichhoff’s section 
+ + to which Xyleborus obliquecauda, Mots., X. aquilus, 
M., and X. validus, Hichh., belong. It is most like the 
last species, but does not resemble it very closely, and 
may be the male of a species of which Mr. Lewis has 
not taken the female. 
TRYPODENDRON, Steph. 
‘There are at present two Japanese species, one of which 
is merely a geographical variety of the European Trypo- 
dendron quercus, Kichh. 
Trypodendron quercus, Hichh., var. niponicum. 
Majus, prothorace pro maxima parte nigro, plaga basali testacea, 
elytrorum lateribus ad versuram apicalem angulatis, subproductis, 
apice utrinque distincte sinuato. Long. 36—4 mm. 
A dozen examples taken at Miyanoshita, and one at 
Oyayama. 
The black patches on the thorax and the elytral vittz 
are of the same shape as in the type, but better marked, 
the thorax being suffused as a rule with black except at 
the base, and the elytral vittee reaching the base in all 
mature specimens. ‘he most distinct character is the 
prominence of the angle of junction between the sides of
