 terminating in a sharply pointed cusp. Median carina dis- 

 tinct, sharp, nearly horizontal, with sometimes a slight 

 depression opposite the elytra. Wings and pronotum con- 

 siderably passing the posterior femora.

 the pronotum sinuate in [jrofilo, being more or less depressed 

 between the shoulders, and at the pronotal apex.
