UROPLATOPSIS. 57 
and transversely notched on each side, the dark-coloured portion of the others with crowded and irre- 
gularly packed granular points, the apices obtuse ; beneath piceous, the sides of the metasternum coarsely 
punctured ; legs moderately slender, brownish-piceous, the anterior femora at the base and apex, and 
the intermediate and posterior pairs at the apex, testaceous, the femora and tibiz sparsely clothed with 
long hairs. 
Length 6-74 millim.; breadth 13~13 millim. (¢ @.) 
flab. Panama, Bugaba (Champion). 
Two examples. JU. reticulata is closely allied to U. planicollis; it differs, however, 
in the shallowly and indistinctly canaliculate head, the more coarsely rugose thorax, 
the basal margin of which is narrower and less raised, and in the third elytral interstice 
not being costate, as well as in colour. The dark-coloured portion of the elytra (instead 
of having a closely-packed double row of granules on each interstice) is accompanied 
by a difference of sculpture, the interstices having on this part more irregularly-packed 
fine granular points. | 
5. Uroplatopsis mimica, (Tab. III. fig. 12, ¢.) 
Elongate, subopaque, clothed with scattered erect hairs; black, the head in great part, a broad stripe on each 
side of the disc of the prothorax extending from the base to the apex (leaving a rather broad longitudinal 
median stripe, and the sides, narrowly, of the ground-colour), and rather more than the basal half of the elytra 
(except the suture.and epipleure) dull reddish-yellow. Head with a long and very deep groove between the 
eyes and numerous very coarse and deep setiferous punctures, the narrow space on each side behind the eyes 
and the middle of the front coarsely rugose ; eyes convex, moderately large ; antenne black, joint 3 short 
and not half the width or length of 4, joints 4-10 in both sexes very broadly flattened and each angularly 
dilated towards the apex, 4-7 increasing and 8-10 decreasing in width, 7 and 8 the widest—the apical 
joint in the male nearly as long as joints 8-10 united, slightly shorter in the female; prothorax longer 
than broad, a little narrowed in front, and feebly constricted behind, the sides margined at the base and 
apex, the basal margin thick and raised, the hind angles prominent but not acute, the disc broadly and 
longitudinally depressed from the base to the apex and with a very irregular deep oblong depression on 
each side, the surface very uneven and coarsely, irregularly, and closely punctured, the punctures on the 
depressed portion of the middle of the disc running into deep transverse or sinuous ruge; elytra long, 
rounded at the shoulders, the sides almost straight from a little below the base to beyond the middle, very 
deeply punctate-striate throughout, the interstices narrow and very closely and deeply transversely notched 
on each side from the base to the apex, the third, fifth, seventh, and ninth narrowly costate for the greater 
part of their length, the apices obtuse; beneath piceous-black, the sides of the metasternum coarsely 
punctured ; legs rather stout, piceous, the femora towards the base and the coxe more or less testaccous, 
the femora almost smooth, but with a few widely scattered hairs, the tibiee clothed within and without 
with rather long hairs. 
Length 8-9 millim.; breadth 23-23 millim. (¢ 2.) 
Hab. Panama, Bugaba 1000 feet (Champion). 
Four examples. This species bears a most remarkable resemblance to Uroplata 
dimidiata, a species of Hispide inhabiting the same locality (cf. Biol. Centr. Am., 
Col. vi. pt. 2, p. 103, t. iv. fig. 13), the colour, structure of the antenne, elytral sculp- 
ture, &c. being reproduced in a very similar manner. The longitudinally grooved and 
irregularly wrinkled thorax and other particulars described above separate U. mimica 
from the allied species described here.
