Endeodes. The species of this genus are found only 

 on the sea beaches. E. abdominalis is at times quite 

 common at Redondo (April and May): collaris is much 

 rarer, in the south at least, ; and I have found but a 

 single example on Catalina Island: basalis has not yet 

 been recorded from our district. 



Malachius. M. auritus and M. thevenetii are not rare 

 on willow blossoms in early spring; they are generally 

 diffused: inornatus occurs at Pomona from March to 

 May: acutipennis is not rare at the same place a little 

 later in the season: prolixicornis has occurred only at 

 Pasadena, June and July: directtis is known from Los 

 Angeles County and from the San Bernardino Moun- 

 tains: nigrinus and pristinus are, so far as known, 

 found only in the Sierras, at an altitude from 5000 to 

 7000 feet; the latter has been taken only in Los 

 Angeles County; nigrinus ranges from near San Ber- 

 nardino to Lake Tahoe. The species are all found on 

 flowers, and are to be obtained by sweeping and beat- 

 ing. In addition to the above, the following are found 

 in other parts of the State: biguttulus, mirandus and 

 spinipennis at Fort Tejon; macer at Lake Tahoe; and 

 mixtus is from "Cal." without more definite statement 

 of locality. 



Tanaops. T. abdominalis is rather common on flowers 

 at Pomona, Pasadena, etc., in June: longiceps is said by 

 Horn to occur with the preceding, but I have not yet 

 detected it in our district; it is not rare near Lake 

 Tahoe and at Sylvania. 



Microlipus. M. laticeps occurs from San Francisco to 

 San Diego; I have seen specimens from San Diego, 

 Pasadena and Long Beach in our district; it is not com- 

 mon: longicollis is still scarcer, and I have met with it
