Tegrodera. T. erosa, San Diego, Riverside, Owens 

 Valley (race latecincta). Certainly very rare at River- 

 side, but common enough at times at various places on 

 the Desert. Horn states that it occurs in Owens Valley 

 in "the latter part of June, on a low plant bearing blue 

 flowers." 



Phodaga. P. alticeps, Indio, Owens Valley. 



RHIPIPHORID.E. 



Rhipiphorus. R.flavipennis and R. cruentus are rather 

 uncommon, on flowers in the southern Sierras, at an 

 altitude from 1,500 to 5,000 feet; I have taken them in 

 the San Gabriel and San Bernardino ranges; var. rufus 

 of the latter species has occurred at Los Angeles (Fuchs). 



Myodites. M. californicus, Los Angeles County (Van 

 Dyke). 



RHINOMACERID^E. 



Rhinomacer. R. comptus and R. bombifrons occur on 

 conifers, in the Lake Tahoe region: pilosus is described 

 from "Cal." 



Diodyrhynchus. D. byturoides is found in the middle 

 Sierras (Placer County). 



RHYNCHITID.E. 



Auletes. A. nasalis is found near San Diego, also in 

 Los Angeles County; not common: latifrons, Southern 

 California (Casey). 



Rhynchites. R. bicolor, Pasadena, May; San Bernar- 

 dino Mountains, August; common wherever wild roses 

 occur: aureus, Riverside, San Diego, and Ojai Valley, 

 from February to May; San Clemente Island, June 1. 

 A blue variety, supposedly of this species, has been 

 taken in the San Bernardino Mountains. R. ceratoides
