SPECIMENS EXAMINED —47. 
In Fiigur.— April to October. 
Remarks.— L. occidentalis was based on two males and two females 
from California received by Packard from the collections of Edwards 
and Behrens. Of the three specimens (two males and one female) of 
occidentalis now in the collection of the MCZ, only the female can be 
definitely associated with the type series; it is labeled “‘Scopula occt- 
dentalis Packard, California, Edwards” and is hereby designated 
lectotype of the species. One of the males has no locality label; the 
other is from California, but there are no indications that either was 
Edwards’ or Behrens’ material. 
Differences in the genitalia, both male and female, distinguish 
occidentalis from rantalis and similalis and clearly indicate that it is 
a distinct species. 
The adults of occidentalis have not yet been associated with larvae.
