6. Oreodera lacteo-strigata, n. sp. 
O. curta, tomento holosericeo rufo-brunneo vestita : elytris apicem 
versus attenuatis, pone medium fascia pallidiore strigis lacteis un- 
dulatis marginata, prope apicem linea transversa undulata lactea 
ornatis. Long. 6 lin. c? . 
Head brown : eyes rather distant from the central line on 
the vertex. Antennse pitchy-brown, base of joints paler greyish. 
Thorax punctured on the disk as well as along the fore and hind 
margins : the anterior pair of tubercles prominent, conical, 
dusky ; the posterior one slightly elevated ; the lateral ones coni- 
cal. Elytra rather thickly punctured from the base to three- 
fourths the length, punctures large, the basal ones accompanied 
by granulations, each near the base furnished with a longitudi- 
nal ridge-shaped tubercle, slightly hooked behind; the basal 
half is deep red-brown, deepening on the sides to violet-black ; 
the space between the pale-brown median belt and the sub- 
apical transverse undulated line is lighter brown, streaked longi- 
tudinally with dark brown ; the subapical milky belt emits short 
branches, and is edged posteriorly with dark brown ; extreme 
apex light brown : the apex is obliquely truncated ; the external 
angles of the truncature acute, but not produced. Legs and 
under-surface of the body clothed with silky-brown grey pile. 
This species was rare on the Upper Amazons. In facies it 
resembles species of the genus Alcidion (group Acanthocinitse) ; 
it is readily distinguished, however, by the short clavate basal 
joint of the antennae. 
7. Oreodera remotay Pascoe. 
jEgomorpJius remotus, Pascoe, Trans. Ent. Soc. n. s. vol. v. pt. 1. 
O, elongata, minus depressa, postice valde attenuata, tomento holo- 
sericeo violaceo-brunneo vestita : elytris marginibus maculis tribus 
lateralibus punctisque discalibus nonnullis quorum duobus majo- 
ribus pone medium atro-violaceis. Long. 8 lin. $ . 
Head brown : eyes distant on the vertex. Antennae brown ; 
basal half of each joint, from the fourth, greyish. Thorax with 
the disk as well as the fore and hind margins punctured; 
lateral tubercles prominent, acute; anterior dorsal ones acute, 
posterior more obtuse, shining black. Elytra rather elongated, 
tapering to the apex, which is very obliquely truncated, the 
external angles of the truncature produced and acute ; the base 
is densely studded with shining black granulations accompanied 
by punctures; the small rounded violet spots on the disk, near the 
apex, cover each a shallow shining puncture ; the lateral spots 
are merely expansions of the dark violet border, and are placed.
