This South American species expands nearly two inches. 



It is black, with a black and yellow head, and rather long 

 tawnv palpi. The antennae and legs are yellow, and the antennce 

 are pectinated. The thorax is striped and spotted with 

 yellow. The abdomen has four yellow spots at the base, 

 three interrupted yellow bands to beyond the middle, and 

 three spots of the same colour on each side. The wings are yel- 

 lowish and semi-transparent; the fore-wings bordered with black 

 towards the tips, which are widely black, and with a yellowish 

 stripe, bordered with black, along part of the hind border. 

 The hind-wings are black above, yellowish beneath in front 

 and behind. The hind tibice have four rather small spurs. 



This fine species has been known to entomologists for more 

 than a century, but does not appear to have been figured 

 before.
