7. Oreodei'a reniota, Pascoe. 



jEgomorphus remotus, Pascoe, Trans. Ent. Soc, n. s. vol. v. pt. 1. 



O. elongata, minus depressa, postice valde attenuata, tomento holo- 

 sericeo viclaceo-bruuneo vestita : elytris marginibus maculis tribus 

 lateralibus punctisque discalibus nounullis quorum duobus majo- 

 riijus pone medium atro-violaceis. Long. 8 lin. $ . 



Head brown : eyes distant on the vertex. Antennae brown -, 

 basal half of eacb 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, 

 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 much coarser texture than that of most other species of the 

 genus ; it resembles in this respect 0. ghnicu, but it does not lie
