marked; border thick, extending round anterior angles and 
across base, very little reflexed on sides, more strongly so between 
the posterior marginal punctures (7.e., on base and posterior part 
of sides), thickened and most prominent at basal angles; mar- 
ginal channel wide on sides, narrow on base; median line linear, 
very lightly impressed ; two marginal punctures on each side, 
the anterior about 1:5 mm. from anterior angle, the posterior 
about same distance from posterior angle. Elytra of same 
breadth as prothorax (14 x 8 mm.), widest behind middle, a little 
narrowed to base, widely rounded at apex, very comyex, impunc- 
tate, sub-opaque (covered with minute scratches) ; base roundly 
and deeply emarginate between shoulders, abruptly declivous to 
peduncle ; shoulders prominent ; lateral border finely reflexed ; a 
row of umbilicate punctures along lateral margin, two punctures 
on basal declivity of each elytron about middle of width; in- 
flexed margin narrow behind first ventral segment. Prosternum 
sloping to peduncle (not vertical on base), widely and lightly 
excavate between coxe. Ventral segments smooth, impunctate ; 
suture between second and third well marked in all its course. 
Legs not long, rather heavy ; femora compressed ; anterior short, 
wide, thick, very lightly sinuate on lower side near apex; anterior 
tibie wide towards apex, bidentate; external ridge forming a 
slight but marked projection above upper external tooth ; inferior 
ridge weakly developed, irregular, not serrate ; apical plate form- 
ing a thick prominent projection below tarsus; intermediate 
tibie thick towards apex, strongly bidentate externally, the 
anterior tooth at apex, the upper (strong, erect, triangular) about 
apical third ; posterior coxe and trochanters impunctate. 
Length, 28; breadth, 8 mm. 
This species differs conspicuously from WV. elongatwm, Macl., in 
having the elytra without the submarginal row of large punctures, 
and in having the intermediate tibie bidentate externally. In 
these respects it resembles WV. retuswm, Bates, to which it is 
evidently closely allied; but, judging from the description of 
NV. retusum, differs in the anterior tibiz, which are bidentate 
externally, not tridentate (in V. Blackburni the external ridge 
forms a rather prominent, though not dentate, projection above 
the upper external tooth, but the tibiz cannot be said to be tri- 
dentate), and have the inferior ridge and apical plate not differ- 
ing much from those of WV. elongatwm, not with “ two broad con- 
spicuous teeth,” as in WV. retuswm. N. Blackburni, too, seems a 
more convex species, and probably has the humeral angles of the 
elytra less strongly dentate. From WJ. parviceps, Sl., a species 
that has the elytra impunctate, it differs greatly in facies, being 
more convex, the head larger, with the eyes more deeply embedded 
n the orbits, the prothorax less transverse, the intermediate
