DOLiOPIUS Esch. 



While preparing the species of Agriotes for publication finding in the 

 same box a very large series of Dolopius lateralis with all variations, I 

 have found that D. macer Lee. cannot be retained as distinct. It is 

 more slender than the majority of the other D. lateralis, and entirely 

 piceous, but either character is observed in the series, so that they have 

 no value in specific definition. 



D. simplex Motsch. is one of the bicolored forms of lateralis so 

 common in California (G. H. Horn).
