Prov. Parand, Brazil [coll. W. W. Saunders and H. W.

Of similar elongate form to Ommata atrata, &c., but more 

 exactly linear, the thorax being scarcely narrower than the 

 elytra, and not attenuated in front or broader than the head. 

 The whole insect with fine decumbent golden pile, besides long, 

 erect, fine hairs, which are especially long all round the hind 

 legs. The head, legs, and sides of the thorax are waxy yellow ; 

 the antennse are of the same colour, but sometimes varied with 

 black ; the eyes in the male are widely distant both above and 

 below, but the large lower lobes are a little frontal. The 

 thorax is long and cylindrical, closely rugose and opaque, with 

 an indefinite black dorsal stripe. The elytra reach to the 

 base of the terminal segment, and are very minutely rugose 

 and opaque, with a few larger punctures. 



The terminal ventral segment (male) is short, with the 

 apical margin broadly and deeply notched.
