size, different colour, and the less dilated antennal joints, the smooth and glabrous femora 
separate U. vermiculata from U. reticulata. 
8. Uroplatopsis planicollis. 
Elongate, opaque, sparsely clothed with erect hairs; reddish-ochraceous, the head in front, the neck, the eyes 
and oral organs, a longitudinal stripe down the middle of the prothorax (sometimes indistinct), and the 
suture of the elytra narrowly, to about the middle, piceous or fuscous. Head deeply longitudinally grooved 
between the eyes, coarsely rugose in the middle in front, and with numerous coarse deep setiferous 
punctures, the eyes convex and rather small; antennx black, joints 3-10 in both sexes broadly flattened 
and each angularly dilated towards the apex, 3 much shorter and narrower than 4, the intermediate joints 
the widest—the apical joint in the male about as long as 8-10 united, very little shorter in the female; 
prothorax rather longer than broad, a little narrowed in front and (if viewed from the side) moderately 
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 scarcely 
visible from above), the broad space enclosed flat and very rugosely (but shallowly) punctured, a narrow 
space within the lateral margin similarly punctured, the hind angles prominent, the basal margin rather 
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 third, fifth, seventh, and ninth 
interstices narrowly costate nearly to the apex, and very closely and deeply transversely notched on each 
side, the second, fourth, sixth, and eighth each with a double row of closely-packed granules, the apices 
each with a short tooth within the angle ; beneath varying in colour from piceous to brownish-testaceous, 
the sides of the metasternum coarsely punctured; legs moderately slender, piceous, the basal half or 
the middle of the femora more or less testaceous, the femora and tibis somewhat thickly clothed with long 
hairs. 
Length 7-84 millim.; breadth 17-2 millim. (¢ 9.)

Numerous examples. From U, mimica this species may be at once distinguished by 
the very broadly flattened and rugose disc of the thorax, the more slender and more 
hairy legs, and the second, fourth, sixth, and eighth elytral interstices in the form of a 
double row of very closely packed granules, the other interstices being narrowly costate 
and closely and transversely notched on each side nearly to the apex. ‘The antenne 
are similarly formed, but not quite so broadly serrate. 
4. Uroplatopsis reticulata. (Tab. III. fig.11, 2.) 
Elongate, subopaque, sparsely clothed with erect hairs; black, the head between and behind the eyes, the sides 
of the prothorax broadly, and the sides of the elytra from the shoulder to about the middle (but rapidly 
becoming more narrowly so) flavoug, and slightly shining. Head shallowly grooved between the eyes, 
coarsely rugose in front, and with numerous coarse deep setiferous punctures, the eyes convex and rather 
small; antenne black, joints 3-10 in both sexes broadly flattened, and each angularly dilated towards the 
apex, 3 much shorter and narrower than 4, the intermediate joints the widest—the apical joint in the male 
about as long as 8-10 united, scarcely shorter in the female; prothorax rather longer than broad, a little 
narrowed in front and (if viewed from the side) feebly 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 scarcely visible from above), the broad space enclosed 
flattened and very coarsely and deeply rugose and at the sides irregularly depressed, the hind angles 
rather prominent, the basal margin narrow and moderately 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 fifth, seventh, and ninth interstices narrowly costate for the greater part of their length
