oblique distal truncation, as found in chutnash, the margin 

 being there moderately denticulate, about intermediate 

 between the typical conditions found in californicum and 

 chumash. The presence of a geographic race or distinct 

 species in the southern Sierras is a possibility which addi- 

 tional material, including adult males, alone can determine. 



Though we have consistently endeavored to secure material 

 of this genus whenever working on the Pacific Coast, all 

 efforts have been unsuccessful.^ 



The species is now known from Bair's Ranch on Redwood 

 Creek in Humboldt County, California, southward along the 

 coast as far as Carmel in Monterey County. It is also found 

 in the Sierras, being here recorded from the vicinity of Lake 

 Tahoe, in Eldorado County, and from Kings River, in Fresno 

 County. As is true for many secretive species, the actual 

 distribution of this insect is probably considerably more 

 extensive than as at present defined. 



Specimens examined, in addition to 6 previously recorded: 28; 8 males, 

 17 females, 3 immature individuals.

^From the data at hand the species of Timema appear to be spring 

 forms, reaching their greatest numerical abundance in May or June. 

 Our Californian work has all been accomplished much later in the season, 

 this probably in large part accounting for our failure to find the insects.
