 apex slightly narrower than base; frons narrowest at base between 

 eyes, sides slightly arcuate, median carina simple; antennae reaching 

 to base of clypeus, first joint slightly more than half the length of 

 second: lateral pronotal carinae not divergingly curved, straight, 

 diverging, not quite reaching hind marsin, or If they do they are

 anal spines contiguous at base, divergingly curved to apex; styles 

 small, their bases generally concealed within the pygopher so that 

 they appear curved and acute, but dissected out and viewed flat thev
