I'ainily Himantariidae 



Antennip short, strongly flattened, broad at base and markedly attenuated 

 distad. Labrum well developed, composed of a single piece which is free, and 

 incurved and dentate along the margin. NLindible with a single dentate and with 

 several pectinate lamella". I'rehensorial feet we.akly developed, not dentate 

 within. The ventral pores are in a sharply delimited central area. Anal pores 

 never present. 



The two genera iiieludi-d in the key below are the only C'alifornian genera at 

 present known; but Ilaplophilus, which is known from Montana and .Mississip])i, 

 may be found to occur.
