 base of the median segment strongly longitudinally striated. 

 First abdominal segment twice as broad as long ; pygidial 

 area transversely riigulose, nearly three times as long as 

 broad, the sides almost parallel, truncate at the apex. Ven- 

 tral segments more sparsely and finely punctured ; second 

 segment without a raised basal area, sixth segment deeply 

 and narrowly emarginate and ending in two small spines on 

 each side, the outer spine the shortest. First recurrent 

 nervure received at three-fifths from the base of the second
