Monerma Beauv.,

Leptocercus Raf., 
Amer. Monthly 
Mag. 4: 190. 1819. 
In a review of Nuttall’s 
Genera Rafinesque changes 
the name Lepturus R. Br. to 
Leptocercus because of a 
genus of insects by the name 
of Leptura. 
Our one species, Lep- 
turus cylindrica ( Willd.) 
Trin. (fig. 53), is intro- 
duced in salt marshes 
from San Francisco to 
San Diego. At matur- 
ity the spike breaks up 
into the 1-seeded joints. 
The species has no eco- 
nomic value. For other 
species that have been 
referred to Lepturus, see 
Pholiurus.
