or standing out at right angles to the body; surface pinkish 
grey, with a large irregular brownish blotch in the middle, and 
a stripe of the same colour on each side beneath, above the 
sockets of the haunches. Elytra depressed, tapering from base 
to apex, the latter obtusely and obliquely truncated ; base near 
the scutellum slightly convex ; surface punctured, pinkish ful- 
vous or grey, silky, with a few brown spots and patches, namely, 
one on the convex part near the scutellum ; a second, kidney- 
shaped, on the margin near the humeral angle; a third, behind 
the middle, extending as a large angulated blotch towards the 
suture ; and a fourth, small and oblique, near the apex. Body 
beneath and legs pinkish fulvous or grey; front and middle 
thighs with dusky patches. Hind thighs gradually thickened. 
Tarsi greatly elongated, the hind pair nearly as long as the tibiae, 
the basal joint especially being of excessive length. 
This handsome little species was only once met with, namely, 
flying in the evening twilight on the banks of the river at 
S. Paulo, Upper Amazons. It differs from all other species of 
the genus in the length of its tarsi and the slenderness of its 
hind thighs, in which characters it approaches the genus Farm- 
cus'j but the depressed form and general facies make it consort 
better with Lepturges than with Par mens. 
2. Lepturges linearis, n. sp, 
L. linearis, fuliginosus : elytris griseo bilineatis. Long. 4 lin. c? $ . 
Head sooty, with a shining olivaceous pile. Thorax with the 
lateral spines placed near the hind angles, and forming each a 
large acute tubercle separated by an impressed line from the 
body of the thorax ; surface with an impressed dorsal line, sooty, 
varied with silky greyish-olivaceous pile. Elytra greatly elon- 
gated, almost linear, sinuate-truncate at the tips, the external 
angle of the truncature produced and acute; surface coarsely 
but somewhat evenly punctured, sooty brown, each elytron with 
two olive-grey vittse united before reaching the apex. Scutellum 
grey. Body beneath and legs clothed with iron-grey pile. Legs 
rather short ; all the thighs clavate ; tarsi slender and elongate. 
Ega; not uncommon on dry twigs in the forest. 
3. Lepturges flaviceps, n. sp. 
L. elongatus, sublinearis, niger : capite, vittis duabus thoracis, annu- 
loque antennarum flavis. Long. 4 lin. $ . 
Head shining testaceous yellow, with two black vittse extend- 
ing from the front of the eyes to the occiput. Antennae twice 
the length of the body, the basal joint very greatly elongated ;

with the lateral spines placed near to the hind angle; surface
