UROPLATOPSIS. 5d 
coarsely rugose along the middle, the epistoma smoother, the base with very coarse scattered setiferous 
impressions, a narrow convex space along each side of the inner margin of the eye and the orbits smooth, 
the eyes convex ; antenne fusco-ferruginous or fusco-piceous, the basal joints darker, joints 3-10 very 
broadly flattened and each angularly dilated towards the apex, 7 and 8 the widest, 3 very much narrower 
and shorter than 4, 11 longer than 8-10 united; prothorax longer than broad, slightly and somewhat 
obliquely narrowed in front and (if viewed from the side) strongly constricted behind, obsoletely margined 
at the sides, with a sinuous, smooth, shining, raised space on each side extending from the base to the 
apex (the true lateral margin placed almost beneath this, and posteriorly scarcely visible from above), the 
broad space enclosed flat, and, like the sides, very rugosely punctured, the hind angles very prominent, 
the basal margin broad and much raised ; 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 inter- 
stices each with a double (the sutural with one) row of very closely-packed granules which extend to 
the apex, the fifth and ninth nearly to the apex (the fifth sharply), and the seventh at the base, costate 
and smoother, and closely and transversely notched on each side, the apices each armed with a sharp 
triangular tooth within; beneath varying in colour from piceous-brown to testaceous, with the venter 
partly piceous, the sides of the metasternum coarsely punctured ; legs piceous-brown or piceo-testaceous, 
the femora testaceous towards the base, the latter smooth and glabrous, the tibiee clothed with long 
hairs. 
Length 10 millim.; breadth 24 millim. (¢.) 
Hab. Nicaraeua, Chontales (Belt). 
Two specimens only. JU. imitator resembles U. planicollis, and has the thorax 
similarly shaped and sculptured ; it differs, however, in its larger size, still more broadly 
dilated antenne, the groove between the eyes broader and rugose within, the fifth 
elytral interstice sharply (the third not) costate, and also in the smooth and glabrous 
femora. 
2. Uroplatopsis vermiculata. (Tab. III. fig. 10, ¢.) 
Elongate, clothed with a few scattered erect hairs, opaque; reddish-ochraceous, the head in front, the eyes, the 
neck, a narrow stripe down the middle of the prothorax, the scutellum, the suture for a short distance, 
and the apical two-fifths of the elytra black or brownish-black. Head with numerous very coarse seti- 
ferous punctures, coarsely rugose in front, and grooved in the middle between the eyes, the latter convex ; 
antenne and prothorax as in U. imitator; elytra as in U. imitator, but with the double rows of granules 
of the interstices replaced on the dark-coloured apical portion by crowded minute granular points, the 
fifth and the ninth interstices nearly to the apex, and the seventh at the base, costate, the apices each 
armed with a sharp triangular tooth within ; beneath more or less piceous at the sides, the venter in part 
testaceous; legs as in U. imitator. 
Length 9 millim.; breadth 23 millim. (<¢.) 
Hab. Nicaracua, Chontales (Belt). 
Two male examples. Rather smaller than U. imitator, the thorax with a longitudinal 
stripe down the middle and the apical two-fifths of the elytra black or brownish-black ; 
the interstices of the dark apical portion of the elytra sculptured in a ‘different manner 
to the rest of the surface, the double rows of granules being replaced by crowded 
minute granular points. In this last-mentioned character U. vermiculata resembles 
U. reticulata, in which the dark-coloured portion of the elytra is differently sculptured 
from the rest of the surface, the other species of the genus having the dark-coloured 
apical portion (when present) sculptured like the paler parts. Apart from the smaller
