INSECTA SAUNDERSIANA. 
the apex, where its superior and inferior margins meet together; pitchy 
black. Extremities of the mouth pale yellow. Palpi pitchy black. An¬ 
tenna black, constructed as described in the generic characters. 
Thorax subrhombical; apex roundly truncate, less than half 
the width of the base at the posterior angles; sides more obliquely 
widened; posterior angles acute; base, from the latter to the middle, ob¬ 
liquely produced, somewhat emarginate near the angles; middle widely 
rounded, scarcely emarginate; upper side convex, especially longitudinally, 
inclined towards the apex; a thin slight longitudinal channel, becoming 
more and more obsolete towards the base, is impressed in the middle: dis¬ 
tantly punctate, covered with a thick dense ochraceous-yellow pile, with 
the middle of the convex part widely longitudinally denudate, forming a 
band, covered with a thin fuscous pile, divided by a thin yellow line filling 
the central channel. 
Scutellum minute, punctiform, impressed in the middle. 
Elytra oblong-subparallel, more than twice the central length of the 
thorax, this length being one-third more than the width beneath the 
shoulders ; base together deeply semicircularly emarginate for the reception 
of the thorax; produced part behind the angles of the latter rounded, 
with the shoulders callose, elongate, placed rather within the thoracic an¬ 
gles and the sides of elytra, which are abruptly and roundly dilated behind 
the angles, to about the transverse level of the basal emargination at the 
suture, or at about the fourth part of their lateral length ; then subparallel 
or nearly straightly narrowed towards the apex, which is in each elytron 
obtusely rounded, with the sutural angle very obtuse; upper side flat, 
widely flattened along the suture; regularly punctate-striate, punctures 
gradually approximating and minute tow'ards the apex; interstices flat, 
obsoletely and densely punctulate, with the shoulders (which are placed 
between the 6th and 8th striae, leaving the 7th almost obsolete upon their 
callosity) transversely rugulose; interstice between 1st and 2nd striae 
widened at the base, where it is sojnewbat convex; densely clothed with a 
thick ochraceous-yellow pile, leaving on each elytron several denudate 
blackish patches, having a hieroglyphical aspect; namely, 1st, a broad 
band extending from the base through the shoulders, widened inwards to 
the middle of each elytron, where it terminates, traversed by two yellow 
branches rising from the margin, one sub-basal, very oblique, passing 
beneath the shoulder, not reaching to the interior edge,—the other linear, 
subtransverse, slightly directed downwards inside, reaching the two edges,
