like marks, some of which are united near the middle of the 
disk of each elytron so as to form the letter V. Body beneath 
rust-coloured : legs duskj^, base of thighs pale testaceous, the 
tibise in the middle and the basal and claw-joints of the tarsi 
ringed with pale testaceous. 
On dried twigs in the forest at Obydos, on the Guiana side of 
the Lower Amazons; also at Para. A closely allied species, 
having, however, different markings on the elytra, is found at 
Cayenne, and exists in several collections*.

, O. subellipticus, olivaceo-cinereus fusco variegatus : thoracis spinis 
lateralibus prope angulos posteriores sitis : elytris oblique sinuato-

Head and thorax olivaceous ashy. Antennse brown, the third, 
fourth, sixth, and eighth joints with their basal halves pale 
testaceous. Thorax partially punctured, its small acute lateral 
tubercles placed very near the posterior angles, a minute notch 
only appearing between them and the hind margins. Elytra 
subelliptical and depressed, the tips obliquely sinuate-truncate ; 
the centro-basal ridge slightly elevated and crowned with blackish 
hairs ; the basal half of the surface is punctured, and the colour 
is the same as that of the head and thorax, but varied with small 
olive-brown specks placed partly in rows, and an undulated 
fascia of the same behind the middle interrupted at the suture. 
Body beneath and legs yellowish testaceous, thinly clothed with 
ashy pile ; apex of femora and tibise and middle part of the 
tarsi blackish. 
Taken on dead slender branches at Santarem and on the 
banks of the Tapajos. At Villa Nova, on the banks of the 
Lower Amazons, I obtained one example, which differs consider- 
ably in colour from the Tapajos form. This may be called 
Local var. 0. pallipes. Same size and shape as the type. 
General colour tawny ashy. Antennse with the basal joint red- 
dish, the remaining joints dusky, with the basal portions of the
