INSECTA SAUNDERS! AN A. 
inserted in a deep fovea under the lateral ridge of the rostrum, close to the 
eyes, and separated from them by a raised ridge, which continues that of 
the rostrum angularly downwards ; 1st joint oblong-ovate, concealed when 
observed from above the rostrum; 2nd shorter by one-half, obovate, trun¬ 
cate, one-half longer than wide ; remainder wanting. 
Thorax transverse, nearly one-third shorter than the width of its base ; 
apex truncate, narrower by one-third; sides roundly dilated towards the 
middle, thence slightly emarginated before the posterior angles, which are 
produced laterally, but obtuse ; base slightly sinuated, appearing to be 
margined by the posterior ridge, which is very close to it, and is angulated 
at the side, nearly confounded with the true angle, but separated, thence 
forming the margins of the sides for two-thirds, where it finishes, leaving 
the apical third without the carina; upper side most convex transversely, 
especially on the anterior part, which is subpulvinate ; there is a little im¬ 
pression above the middle of the base; punctate-rugose, black, covered with 
a grayish fulvous pile, here and there yellowish or subochreous, condensed 
at the middle and base in several lighter punctiform spots, leaving also 
some indistinct denuded places, of which two short thin oblique lines 
at each side of the basd are the best indicated and circumscribed. 
Scutellum transversely subovate-quadrate, clothed with a yellowish 
fulvous pile. 
Elytra oblong-subparallel, nearly thrice as long as the thorax, together 
half the width of their length ; base very obtusely rounded, marginated, 
basal margin somewhat continued behind the shoulders, which are obso- 
letely callose and placed within the thoracical angles; sides parallel from 
the base to three-fourths of the length, then roundly narrowed towards the 
apex, which on each elytron is slightly emarginate, with the sutural angle 
acute, subspiniform ; most convex transversely; there is behind the base a 
transversely subrhombical elevation, of which the sides, and particularly 
the angles, are evanescent, the supposed basal angle being cut away by the 
base of the elytra and the scutellum ; the supposed posterior angle also cut 
away at the suture by a transverse impression, placed at one-third of 
the length ; they are from that impression to the apex longitudinally regu¬ 
larly convex, without any other transversal or longitudinal impression ; 
they also have no callosity above the apex, and are remotely punctate- 
striate, the innermost stria duplicated at the base upon the gibbosity, its ex¬ 
ternal brauch ejected obliquely outwards, ejecting in the same manner the 
other striae ; suture and alternate interstices slightly convex, the remainder
