192 Mr. Walter F. H. Blandford on the 
of club very oblique. Prothorax rather broader than long (its 
apparent length varying according to the angle at which it is 
viewed), base truncate, basal angles obtusely rounded, sides 
rounded, above obliquely declivous and flattened anteriorly, the 
declivity prolonged backwards in the middle line to basal third, 
anterior border produced in a line with the declivous surface into a 
transverse lobe, covering head, its margin rounded and elevated ; 
surface obtusely elevated behind apical lobe and at sides of declivity, 
closely punctured, and with a more or less evident smooth median 
line from base to middle, the punctures, finely asperate anteriorly 
for a variable distance, interspaces finely reticulate. Scutellum 
small, rounded triangular. Elytra narrower than prothorax, an 
about one third longer, base truncate, basal angles rounded, humeral 
elevations scarcely traceable, sides parallel to behind middle, thence 
rounded to apex ; surface convex, subcylindrical at basal half, with 
indistinct rows of punctures, interstices multipunctate, apex 
very strongly but obliquely declivous, the declivity subconvex, 
circular in outline, not acutely margined, granulately punctured 
and indistinctly striate. Legs rather long, apices of anterior tibi» 
subtruncate, outer margin of middle and posterior tibie broadly 
rounded serrate. 
The specimens vary in colour, gloss, and the closeness 
and degree of asperity of the thoracic sculpture. One 
example from Higo is at first sight very different. It is 
smaller, darker, more truncate, with the prothorax 
shorter and the anterior lobe more declivous. It may 
quite possibly be the male of a different species, but 
presents no essential differences of structure or sculp- 
ture. ’. cucullatus is perhaps the male of X. brevis, 
Eicbh., and is certainly allied to it; but the Higo ex- 
ample alone appears small enough to stand as the male 
of that species, and in all the rows of punctures on the 
elytra are more evident than in _X. brevis. The specimen 
from Kurigahara has been placed, by Mr. Lewis, on the 
same card with the next described species, as the 
corresponding sex. But I do not see my way to accept- 
ing this. If it be so, XY. cucullatus must be the female, 
and in all characteristics it isa male; the generative 
organs, as far as I have been able to examine them, agree 
with those of Y. dispar g, the elytra appear to be 
soldered, and the wings are either completely absent or 
very minute.
