one at a third, another at two-thirds the length of the elytra, and 
the third, much smaller one, near the apex. Under-surface of the 
body and legs clothed with ashy-brown pile. The tarsi, espe- 
cially the claw-joints, are remarkably elongated. 
Taken at St. Paulo on the Upper Amazons, on the slender 
trunk of a dead standing tree. The pile covering this species is 
of a mueh coarser texture than that of most other species of the 
genus ; it resembles in this respect O. glauca, but it does not lie 
so compactly as in that species. The species was referred by Mr. 
Pascoe to the j^gomorphus oi Dejean,- which, however, had 
not at that time been characterized, and was a loose assemblage 
of species belonging to four or five different genera. 
8. Or coder a sericatOj n. sp. 
O. valde depressa, fulvo-brunnea, tomento tenuissimo holosericeo 
griseo subtus densiore vestita : elytris plaga magna laterali pone 
humeros albo-grisea, prope basin punctatis, dimidio apicali Isevis- 
simo. Long. 5| lin. 
Head brown : eyes distant on the vertex : antennae piceous. 
Thorax with the lateral tubercles obtuse, the three dorsal ones 
very slightly elevated and clothed with pile. Elytra obliquely 
truncated at the apex, sutural angles rounded off, the external 
ones obtuse ; base with a number of large simple punctures, 
which do not reach beyond one-third the length except along 
the sides, the rest perfectly smooth and silky; the pile is ex- 
tremely fine, thin, silky, and changeable. Legs clothed with 
grey pile. Under-surface densely clothed. The white patches 
on the elytra reach the suture and occupy nearly one-half the 
surface. 
Taken at St. Paulo on the Upper Amazons. 
9. Oreodera cretata, n. sp. 
O. depressa, apicem versus attenuata, tomento tenuissimo holosericeo 
fulvo vestita: elytris plaga oblonga laterali apud medium cretaceo- 
alba. Long. lin. 
Head and antennse fulvous : eyes rather distant on the vertex. 
Thorax with the lateral tubercles obtuse and the three dorsal ones 
only slightly indicated ; punctured on the hind part of the disk 
as well as along the fore and hind margins. Elytra truncated 
obliquely at the apex, sutural angles very obtuse, external ones 
slightly produced and acute; punctured, partly in lines and 
sparingly over the basal half. The oblong lateral chalky spot 
is clear white. Body beneath and legs silky fulvous. 
On the banks of the Cupari (R. Tapajos), on dried branches.
