48 CALIFORNIA ACADEMY OF SCIENCES. 



Ega. E. Icetula, found at East Bridge, on the 

 Arizona side of the Colorado, by Mr. Wickham, and 

 without a doubt occurs also on the California side; 

 found also at Yuma. 



Tetragonodera. T. fasciata, margin of Colorado River; 

 Yuma, July: pallidus, one specimen, taken under dried 

 remains of Opuntia, Pomona, May; others under boards 

 at Palm Springs in April; a very active insect and every- 

 where rare; so far as observed, it does not seem to share 

 the littoral habits of its congeners. 



Lebia. L. cyanipennis, not rare: ruficollis, much less 

 frequent; Riverside, April; Redondo, March: viridis, 

 quite common in numerous localities; generally smaller 

 than Eastern specimens: furcata, one example, Pomona, 

 July: guttula, usually rare; occasionally found in small 

 colonies under the loose bark of Eucalyptus in December 

 and January: bilineata, San Bernardino Mountains, 

 July; rare. 



Dromius. D. piceus, not rare under bark of live-oak in 

 foot-hills near Pomona in February and April. 



Apristus. A. laticollis, rather common on banks of 

 streams or ditches, and occasionally running on garden 

 walks, usually in April and May. 



Blechrus. B. glabratus and B. lucidus occur in situ- 

 ations similar to the preceding, but are less common. 



Axinopalpus. A. biplagiatus, not rare under Eucalyp- 

 tus bark in winter: fusciceps, only one specimen seen, 

 Los Angeles County (Van Dyke). 



Tecnophilus. T. croceicollis is said by Horn to occur 

 " from San Diego to Oregon," but I have not yet met it. 



Callida C. platynoides, "Mountains east of Visalia" 

 (Horn).
