INSECTA SAUNDERSIANA. 
thin and obsolete, rather more strongly indicated on the forehead (front), 
and another intra-lateral on each side observable from the apex to the pos¬ 
terior limit of the antennal groove, thence very obsolete to the eye; the base 
transversely impressed, from it to the apex sensibly widened, where it 
is hardly narrower than the hinder part of the head; its sides between the 
eye and the antennal groove are subconvex, or scarcely flattened, rugulose ; 
its apex is triangularly emarginate ; antennal groove shallow, ovate, and 
very obsoletely continued underneath. Labrum transverse, subconically 
raised in the middle of the emargination of the rostrum. Mandibles 
slightly thickened, incurved, acute. Mentum convex, widely triangularly 
emarginate, each lobe subincurved, obtusely acute, obliquely rugulose 
at its base. Palpi rather slender, filiform ; apical joint having some rigid 
hairs. 
Thorax subobliquely truncate at the apex, narrowly margined on each 
side under the eye, with a very shallow wrinkle beneath that emargination ; 
sides in front subconvex, thence subemarginately dilated towards the posterior 
carina (which is there angularly produced laterally), then emarginately 
obliquely narrowed to the base, where the thorax is much broader than at 
the apex; posterior carina very highly raised, not interrupted in the 
middle, straightly parallel to one-third of the length of the side, thence ob¬ 
tusely angular, afterwards obliquely directed in a straight line upwards to 
the side : disc with transverse shallow impression near the base, somewhat 
elevated behind that impression a little above the middle, there shallowly 
impressed in front of the posterior carina; rather convex transversely; 
clothed with a light green lutescent tomentosity, densely scattered with 
whitish on the disc, varied with fuscous marks: two apical short thin 
lineolae, equidistant from each other and the sides, two large basal 
maculae extending a little (punctiformly) above the posterior carina nearer 
to the sides, and two others obsolete, punctiform, each at the side of 
the median transversal elevation, a little farther from each other than the 
basal ones, very near to the sides. 
Scutellum small, rather longer than broad, subquadrate, clothed with 
whitish tomentosity. 
Elytra truncate and margined at the base, rather obliquely dilated 
for the shoulders (which are callose), broader at that part than the thorax ; 
sides subparallel to two-thirds of the length, thence slightly narrowed 
towards the apex, which is obtusely rounded, with a narrow emargination 
near the suture, and the sutural angle subspiniform ; disc rather flattened ;
