Hab. Amazons, Ega (H. W. Rates). 



This species has the anterior tibiae rather more abruptly 

 enlarged on the inner side at the base than in the other species 

 I have been describing. The two examples before me differ 

 considerably in the punctuation of the thorax, one having it 

 extremely fine, the other much more distinct. The elytra 

 have the striae moderately deep, the punctures in them very 

 distinct and somewhat separated from each other. The 

 pygidium is pitchy, with a green tint. The posterior legs 

 have the tibiae short, suddenly enlarged at the base on the 

 inner side, forming an obtuse angle, thence to the apex gradu- 

 ally widened, the outer apical angle not produced ; the basal 

 joint of the tarsi at least twice as broad as long, deeply trian- 

 gularly emarginate at the apex, with the outer angles 

 prolonged (PL XI. fig. 3).

 corpore subtus piceo-nigro obscure aeneo tincto, abdoaiine apice 

 cupreo, pygidio virescenti ; capite fere Ja)vi, clypeo antice leviter 

 emarginato, medio bidentato ; thorace medio fere loevi, latera versus 

 subtiliter punctulato, medio linea brevi impressa ; elytris distincte 

 striatis, striis obsolete punctulatis, interstitiis fere planis, obsolete 

 punctulatis ; pygidio subtilitor punctulato ; tibiis posticis elon- 

 gatis, apicem versus paullo latioribus, angulo externo paullo pro- 

 ducto, tarsorum articulo basali longitudine vix latiori, ad apicem 

 emarginato.

Hab. Brazil {ex coll. Lacordaire) . 



This species is allied to 0. cequah's, but has the elytra a 

 little shorter and more rounded at the sides. The posterior 

 tibiae are elongate, sparingly punctured above (besides the 

 line of punctures), with no trace of median external projec- 

 tion. The basal joint of the posterior tarsi is longer, slightly 

 narrowed towards the base, not very deeply emarginate at the 

 apex, the outer angle scarcely more prolonged than the inner 

 angle (PI. XI. fig. 4).
