§ § Disk of thorax with no trace of tubercles. Elytra less distinctly, 
sometimes scarce perceptibly, truncated at the apex. 
a. Elytra depressed. 
10. Oreodera simplex, n. sp. 
O. elongata, angustata, tomento holosericeo varia sordido olivaceo 
vestita : elytris fasciis tribus abbreviatis indistinctis pallidioribus. 
Long. 5 lin. 
Head and antennae dark brown, the base of each antennal 
joint (from the fourth) ringed with grey. Thorax with the lateral 
tubercles obtuse ; disk uneven, punctured posteriorly and on the 
lateral tubercles as well as along the fore and hind margins. 
Elytra narrow and only slightly tapering, the apices slightly trun- 
cated, punctured moderately over the basal half and on the disk 
to the apex. The pile is of a dingy yellowish olivaceous colour, 
varied with a paler shade, which forms three obscure semi-belts 
on the elytra. Legs and under- surface ashy-brown. 
Ega, on dried branches. 
11, Oreodera griseo-zonata, n. sp. 
O. depressa, apud humeros lata, apicem versus attenuata, tomento 
holosericeo griseo-brunneo vestita : elytris fascia latissima basali 
albo-grisea, apices versus lineis flexuosis griseis brunneisque ornatis. 
Long. 4^ lin. 
Head and antennse brown ; base of each antennal joint (from 
the fourth) grey : eyes distant on the vertex. Thorax with the 
disk nearly even j a few punctures on each side, besides those on 
the fore and hind margins. The elytra have the shoulders more 
produced and pointed than in the allied species, they have a few 
punctures near the base, and the apices are singly rounded : the 
broad grey belt across the basal half has its fore margin arched 
posteriorly, so as to leave a space around the scutellum dark 
brown ; it passes beneath entirely over the mesosternum : the 
grey and brownish waved lines on the apical half are obscure 
and silky. Body beneath and legs pitchy-brown, clothed with 
ashy-brown pile. 
Ega and banks of the Tapajos, on dead twigs. 
b. Elytra somewhat convex. (Subgenus Anoreina.) 
12. Oreodera [Anoreina) nana, n. sp. 
O. curta, convexiuscula, fuliginosa, tomento fusco et flavo-ferrugineo 
vestita ; elytris lateribus rotundatis, apices versus attenuatis, utrin- 
que apud medium macula magna lateral! triangular! albo-grisea. 
Long. lin. 
Head and thorax dark drown : eyes distant on the vertex.
