248 RHYNCHOPHORA. 
Numerous examples. Perhaps a form of C. rectirostris, from which it may be 
separated by the structure of the rostrum, the difference being well-marked in the 
females, and in the feebly-notched anterior femoral tooth. C. guadrinotatus bears a 
somewhat similar relationship to C. tetrastigma. 
10, Conotrachelus latidens, sp. n. (Tab. XVIII. figg. 10, 10a, 2.) 
Oblong-ovate, shining, piceous, the elytra mottled with ferruginous, the antenne, and the rostrum and legs in 
great part, of the same colour; thickly clothed with narrow pale yellowish-brown scales (except along a 
narrow space on the middle of the prothorax behind), the femora with a whitish ring, the anterior pair 
with a fulvous line along their basal half above. Head densely punctate, slightly depressed in front ; 
rostrum moderately stout, curved, nearly twice as long as the prothorax, rugulose and unicarinate, the 
apical portion thickly punctate, the antenne inserted slightly beyond the middle, joints 1 and 2 of the 
funiculus subequal in length. Prothorax broader than long, abruptly narrowed and tubulate towards 
the apex, the disc longitudinally depressed on each side of the middle, the depression curving outwards 
anteriorly, the sides rounded in front and parallel behind, the base strongly bisinuate; densely, 
rugulosely punctate, and finely carinate to near the base. Elytra rather long, subtriangular, flattened 
on the disc anteriorly, the humeri prominent, obliquely truncated; seriate-punctate, the interstices 
densely rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 and 7 interrupted below the base, 
that on 3 curving towards the suture posteriorly. Intermediate coxw rather narrowly separated, the 
mesosternum somewhat raised between them and declivous in front. Ventral segments finely punctate. 
Legs stout; femora strongly clavate, each with a large triangular tooth. Tarsal claws with a very 
short tooth. 
Length 7+1,, breadth 34 millim. (9.) 
fab. Panama, Bugaba (Champion). 
One specimen. A large species, with close, uniform, pale brownish vestiture, the 
disc of the prothorax hollowed down each side of the middle, the elytral coste 
uninterrupted posteriorly, the femora each with a large triangular tooth. It approaches 
C. fulvomaculatus. 
11. Conotrachelus varicolor, sp.n. (Tab. XVIII. figg. 11, lla, ¢ .) 
Subovate, shining, black, the head in part, the front of the prothorax, a broad humeral patch on each elytron, 
and the apex of the latter, more or less ferruginous, the antenne and legs also of this colour, except that 
the intermediate and posterior femora are black in their basal half; the vestiture fine and rather close, 
fulvous or ochreous, dense at the sides of the prothorax, which are faintly bilineate with white (there 
being an oval space on the disc, interrupted by a faint median line, much more sparsely clothed), the 
alternate elytral interstices (except at the base and apex) whitish, the clothing of the under surface and of 
the dark portions of the femora also white, the latter obsoletely annulate. Head densely punctate, faintly 
foveate between the eyes; rostrum ( ¢) stout, curved, about twice as long as the prothorax, rugulosely 
punctate and 5-carinate, thickly punctured at the tip, (Q) much longer and smoother, shallowly striate 
towards the base, sparsely punctate throughout, the antenne inserted at the middle in the Q and at 
one-third from the apex in the d, joint 2 of the funiculus shorter than 1, 6 and 7 transverse. Pro- 
thorax strongly transverse, narrowed and constricted in front, deeply bisinnate at the base, densely, 
rugulosely punctate. Elytra subtriangular, about one-half wider than the prothorax, strongly sinuate at 
the base, the humeri prominent, but obtuse; coarsely seriate-punctate, striate near the suture, the 
interstices rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 abruptly twice interrupted, the 
median elevation on 3 very prominent. Mesosternum simply flattened between the coxe. Ventral 
segments sparsely, very finely punctate, 5 foveate at the apex in the ¢. Femora clavate, acutely
