what luteous towards the base, less roughly punctured than the thorax, 
much attenuated towards the tip, which is very acute. Abdomen slightly 
keeled beneath; hind angles of the segments successively more elongated 
and acute, those of the apical segment forming two long spives, which are 
blackish towards the tips. Legs luteous. Fore wings smooth, reddish
