INSECTA SAUNDERSIANA. 
raised in the middle, obsolete towards its sides, which are somewhat 
projected upwards beyond the basal angle of the thorax, where they are 
subangular; thence the base is slightly obliquely dilated to the shoulders; 
these are obtusely angular subcariniform; the sides slightly narrowed to 
four-fifths of their length (more so in the males), thence obliquely roundly 
narrowed to the apex, which is subemarginately truncate; disc very slightly 
depressed, sides roundly convex, thick; longitudinally they are first a little 
elevated behind the base, then shortly impressed, afterwards not quite 
straight, but subconvex, and with a more evident declivity on the posterior 
part, to the callosity, which, though rather elongate by being narrowed at 
its base (a character which separates it immediately from the preceding), 
and resembling a tubercle, does not reach the perpendicular level of the 
apex, which is subobliquely depressed, and forms the continuation of the 
posterior declivity, the callosity not extending widely, as in the preceding, 
upon the elytra, but being detached. This character of a regular circular 
declivity leads naturally to the following species, in which the callosity is 
shorter, and finally to those in which it is entirely wanting. Their colora¬ 
tion is more mixed than in the above-described species; their common 
longitudinal band is slightly determined, the sides being densely variegated 
with its colour, which is of a greenish or olivaceous white, mixed with 
numerous olivaceous dots; the ground of the sides is of a greenish oliva¬ 
ceous hue, darker on the emarginations of the band, and laterally densely 
mixed, as above said, with the olivaceous white of the band. 
Pygidium semiovate, oblique, with a ridge in the middle: the ridge 
not reaching to the apex, which is deflected. 
Body beneath clothed with whitish, lighter and less olivaceous pile 
than the upper band; segments of the abdomen marked at the base on 
each side with a subquadrangular olivaceous macula. 
Obs .—I have seen a number of this fine and robust species.
