Listronotus. Two undescribed species of this genus 

 are known from our district. One of these is near tere- 

 tirostris; it has been taken at San Diego, Pomona, and 

 Antelope Valley. Of the second species, a small form 

 near gracilis, one example only has been found by me at 

 Long Beach . 



Macrops. M. hyperodes and M. californicus are known 

 from the central or northern parts of the State. 



Emphyastes. E. fucicola is not uncommon along the 

 sea beaches, beneath sea-weed, etc. 



Lixus. L. asper, not frequent at San Bernardino, on 

 Rumex (Wright): perforatus, not rare at Pomona, March 

 to June: semivittatus, specimens which do not appear to 

 differ from typical Arizona examples of this species are 

 not rare on and about the roots of a plant growing 

 along the sand-dunes near the beach at Santa Mon- 

 ica: auctus is northern: parcus is described from San 

 Francisco. 



Dinocleus. One specimen of pilosus found at Coro- 

 nado in July is scarcely different from the Le Conte 

 type. The type is without exact locality but is doubt- 

 less from the south, and probably from the same region. 

 D. jacobinus is described by Casey from San Diego: 

 farctus, from "near the southern boundary:" albovesti- 

 tus is not rare near Los Angeles in August and Septem- 

 ber: molitor is common on the desert at Indio and 

 Yuma: wickhami was taken by Mr. Wickham at Indio. 



Cleonus. C. inornatus, Owens Valley: jxicificus, one 

 example at Redondo in April, on Astragalus crotalarce: 

 erysimi, not rare at Redondo on flowers of Erysimum 

 asperum, March and April: lobigerinus, from the south- 

 east: vittatus, Owens Valley, if Casey is correct in his
