 less graceful, a trifle shorter than the pronotum. Lateral lobes 



of the pronotum highest at middle Prosagoga Brunner. 



dd. Fastigium of the vertex contiguous with the fastigium of the front. 

 (In Pycnopalpa bicordata it is not contiguous, and in this case the 

 margins of the antennal scrobes are rather distant.) 

 e. Anterior femora dentate below on the anterior border. Anterior 

 tibiae above dilated in the apical portion and provided with an 

 external spine. Tegmina ovate, in their apical third three 

 times as wide as the length of the pronotum. 

 /. Disc of the pronotum ornamented with two roughened heart-
