COLEOPTERA OF SOUTHERN CALIFORNIA. 197 



May. Of T. prolixus one specimen has been found, also 

 on Lupinus, at Pomona in May: setosus is obtainable in 

 numbers on mesquite in the Colorado Desert; and with 

 it is what appears to be an allied, undescribed species: 

 semisquamosus is reported from Tejon. 



Sibynes. 8. fulvus, San Bernardino County. 



Paragoges. P. maculatus is an uncommon insect

 and Alameda County. 



Conotrachelus. C. duplex, ' ' California probably 

 southern" (Casey). 



Rhyssematus. R. pubescens is a rare species of which 

 I have seen but two examples; one swept from flowers

 light at Pasadena in April. Horn's type was obtained 

 in Owens Valley. 



Micromastus. M. gracilis, San Francisco. 

 Tyloderma. T. morbillosum, San Francisco. 

 Zascelis. Z. irrorata, "Gal., Nev., Col." 



Piazurus. P. californicus is abundant on pines in 

 the Sierras. 



Copturus. The type of mamiilatus was probably from 

 San Diego County, though the exact locality is not 

 known. The only other examples seen by me were 

 taken by sweeping weeds along the Colorado River at 

 Yuma, and a single specimen from Ensenada, Lower 

 California. G. adspersus is our commonest species; it 

 is obtained by sweeping weeds in waste places, and is 

 wide-spread: longulus is found only on coniferous trees 

 in the higher parts of the Sierras. In the northern
