-UROPLATOPSIS. 59 
8. Uroplatopsis excavata. (Tab. III. fig. 14, 2.) 
Elongate, narrow, subparallel, thickly clothed with erect hairs ; the head and prothorax shining, the head piceous- 
brown, testaceous between the eyes, the prothorax testaceous, with a broad or mcderately broad longitudinal 
piceous stripe on the middle of the disc extending from the base to the apex; the elytra dull, flavo-testaceous, 
with a small (in the female) perfectly opaque fulvous lateral patch about the centre, the apical portion from 
a little below the middle fusco-piceous, this colour extending along the suture and widening out a little 
towards the base. Head with scattered very coarse setiferous punctures, sparsely and finely punctured in 
front, shallowly canaliculate between the eyes, the latter convex and moderately large; antenne black, the 
apical two-thirds of the last joint flavous, joints 3-10 very broadly flattened, and each angularly dilated 
towards the apex, 6-10 very sharply so, 3 the length of but narrower than 4, 11( 2) about as long as 7-10 
united ; prothorax longer than broad, a little narrowed in front, and feebly constricted behind, the. sides 
completely immarginate, the hind angles prominent, the disc deeply canaliculate in the centre anteriorly and 
with a very deep <-shaped impression on each side about the middle, the basal margin much raised and 
preceded by a deep groove extending completely across, the surface with a few widely scattered fine 
punctures, the disc smooth ; elytra very long, subparallel nearly to the apex, the disc flattened, the sides 
towards the base almost vertical from the sixth row of impressions, the surface with regular rows of deep 
foveate rounded impressions which extend to the apex, the interstices quite narrow and convex, each with 
a row of closely placed very fine setiferous punctures extending from the base to the apex, the fifth and 
seventh towards the base and the ninth towards the apex broader and costate, the apices obtuse ; beneath 
entirely piceous ; legs rather long, piceous-brown, the femora and coxe piceo-testaceous, the femora and 
tibia sparsely and rather deeply punctured and somewhat thickly clothed on all sides with very long 
hairs. 
Length 63 millim.; breadth 14 millim. (@.) 
Hab. Panama, Bugaba (Champion). 
One female example. This species closely resembles U. simulans; it differs thus :— 
The apical joint of the antennz is in great part flavous; the head is smoother and 
more sparsely punctured, the coarse deep punctures on the vertex being distant from 
one another and not confluent; the prothorax is almost smooth at the sides; and the 
elytra have the foveate impressions coarser, more rounded, and less numerous (owing 
to their more rounded shape and larger size), aud the fusco-piceous apical patch very 
much larger. From U. dilaticornis the smoother sides of the thorax and the larger and 
less numerous foveate impressions of the elytral series sufficiently distinguish it; the 
former, moreover, has the apical patch gradually (and not abruptly) narrowing anteriorly 
and broadly extending along the suture to the base. | 
9. Uroplatopsis appendiculata, (Tab. III. fig. 15, 3.) 
Very elongate, narrow, subparallel, shining, sparsely clothed with long erect hairs, testaceous ; the prothorax 
with a broad longitudinal piceous stripe on the middle of the disc extending from the base to the apex; 
the elytra flavous, with (in the male) a large, oblong, perfectly opaque, fulvous lateral patch about the 
middle, and the suture to some little distance below the base indeterminately and rather broadly fuscous. 
Head shallowly canaliculate between the eyes, and with scattered setiferous punctures at the sides and 
base, for the rest smooth, the eyes moderately large ; antenne ( ¢) long and stout, black, the apical joint 
testaceous, joints 2 and 3 about equal in length, each slightly shorter than 4, 3-10 moderately widened 
and each angularly dilated towards the apex, 7 and 8 the widest, 11 exceedingly elongate, equal in 
length to 6-10 united, and much curved; prothorax considerably longer than broad, the sides completely 
immarginate, feebly rounded, a little narrowed in front, and moderately constricted behind, the hind 
angles very prominent, the disc with a small shallow fovea on each side before, and a very deep oblique 
groove on each side behind the middle, the basal margin thick and much raised, and preceded by a deep
