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. laticoUis, rather common on banks of 

 streams or ditches, and occasionally running on garden 

 walks, usually in April and May. 



Blechrus. — B. glahratus 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. — G . platynoides , "Mountains east of Visalia" 

 (Horn).
