O. ovatus, robustus, pubescens, flavo-fuscus ; capite punctato ; 

 thorace transverso, lateribus parcdlelis (Jumd ad basin coarctatis) ; 

 elytris punctatis, striatis, valde pubescentibus, maculis sex circu- 

 laribus ornatis (maculis ad scuteUum et ad apicem fuscis, ad

 quis fuscis. 



Long. corp. 2|-3 lin., lat. li lin. 



Ovate, broad, subcylindrical, robust, pubescent, flavo-fuscous. 

 Head short, slightly produced ; above the labrum is a transverse tri- 

 angular depression ; the surface is thickly and coarsely punctate and 

 impubescent (except at the inner margin of the eyes). Thorax 

 transverse ; the anterior angles subacute and depressed ; the sides 

 marginate and parallel ; the surface is subcylindrical, more distinctly 

 pubescent at the sides, finely punctate. ScuteUum triangular, finely 

 pubescent, impunctate, fuscous. Elytra robust, subparallel, punctate- 

 striate (the striation being almost concealed by the pubescence) ; be- 

 tween the second and fourth striae are placed on each elytron three 

 circular spots, which are formed by a darker colour of the pubes- 

 cence ; those near the scutellum and also that near the apex are in 

 colour fuscous, the central spots being more distinct and black. 

 Antenna short, robust, dilated towards the apex ; the joints third to 

 fifth elongated and slender, sixth to eighth abruptly dilated; in 

 colour, the first to fifth are flavous, sixth to eighth black (the base of 

 the sixth being fuscous), ninth to eleventh flavous. Legs flavous 

 throughout. 



This species differs from 0. bimacidatus in the form of its thorax 

 (the sides of which are parallel, and not constricted at the base), as 

 well as in the six spots on the elytra. 



From Ega (River Amazon).
