sometimes with a feeble greenish tinge. Rostrum, tibie, and 
tarsi with dense, short, stout setæ, on prothorax shorter and 
sparser, on elytra moderately dense, and towards the sides 
and on tubercles becoming longer, darker, and straggling ; 
undersurface and legs with long pale setze. 
Head, rostrum, and antenne as in preceding, except that 
the antenne are thinner. Prothorax subcylindrical, in male 
apparently longer than wide, but at widest as wide (male, 
3 x 3); at sides with numerous transverse irregular impres- 
sions; median line marked in middle by a raised, shining, 
somewhat elliptic tubercle. Klytra considerably wider than 
prothorax at base, shoulders oblique, scarcely dilated towards 
apex in male, strongly in female; seriate-punctate, punctures 
comparatively small and distant; third and sixth interstices 
tuberculate from base to summit of posterior declivit , Which 
is crowned with a transverse row of four large Ант Л соп1- 
cal in male, subconical in female, the outer large tubercles 
are on the fifth (not the sixth) interstice, and immediately 
below them are several smaller ones; several feeble tubercles 
on each side near apex. Length, male 13; female 194; ros- 
trum, male 33; width, male 62, female 102.

This species is reported to be very destructive (both in its 
adult and larval stages) to sugar cane. From the preceding 
species (which it greatly resembles) it may be distinguished 
by its elytral setæ, but especially by the tubercies of the third 
and sixth interstices; in the latter character it approaches 
tuberculata, but the elytra are not at all rounded, as in that 
species, and the prothorax is different. 
LEPTOPS sETOSUS, n. sp. 
Male. Densely clothed with scales having a somewhat cop- 
pery hue, with (especially on the under surface) a more or 
less rosy tinge; elytral tubercles, muzzle, tarsi, сохе, and 
knees more or less distinctly tinged with green. Densely 
ervered with stout, short, testaceous setze, longer and paler 
on antennz except upper surface of scape; abdomen with the 
usual sete more or less intermingled with long, pale, hair- 
like setze. 
Head feebly depressed between eyes. Rostrum stout; 
grooved in middle; a short, deep sulcus towards each side, 
scrobes short, strongly curved, shallow, terminating consider- 
ably before the eyes. Antenne stout; scape short, stout, 
curved; joints of funicle feebly decreasing in width and 
length, the second very slightly longer than the first, the 
otners subeylindrical, but all longer than wide. Prothoran 
considerably narrower at apex than at base, shghtly trans-
