from "Gal." without definite locality: rectangula and 

 imitatrix are northern, the latter occurring also on the 

 Farallon Islands (Fuchs): stupida is described from 

 Sacramento; it is very near jacobince: conflata was de- 

 scribed from San Francisco. There is a specimen of 

 latior in the Le Conte Collection bearing a gold disk, 

 Le Conte's customary California label. 



Badister. B. anthracinus, a single specimen from Los 

 Angeles County (Van Dyke): ferrugineus, "Alaska- 

 Cal."; doubtless confined to the northern part of the 

 State. 



Calathus. The name C.ruficoUisie generally used for 

 our very abundant species, and it is not quite plain how 

 it is to be separated from obscurus, which, according to 

 description, is a "So. Cal." species.* Le Conte described 

 quadricollis from San Francisco, and behrensii is from 

 "Cal." It is impossible to separate these four species 

 by Le Conte's table, and it is more than likely that 

 all the names apply to a single moderately variable 

 species. 



Pristonychus. P. complanatus, San Bernardino, about 

 stables in December; San Diego, uncommon. 



Platynus. P. agilis, found at St. Isabel, San Diego 

 County (Le Conte); I have never taken it: simplex, 

 specimens so referred occur on the banks of the Colo- 

 rado River: frater is recorded as from San Diego and 

 San Francisco; it is unknown to me: brunneomargi- 

 natus, calif ornicus, funebris, maculicollis and variolatus 

 occur nearly everywhere and are generally very com- 

 mon: fossiger and deplanatus are less frequent, the latter 



*ln his list of species from Guadalupe Island (Trans. Am. Ent. Soc , Vol. V, p. 198), Dr. Horn 

 refers a large species of Calathus to C. obscurus. The Guadalupe species appears to me to be dis- 

 tinct, and I believe Major Casey is justified in giving it the name C. guadalupensis in a recent 

 description.
