COLEOPTERA OF SOUTHERN CALIFORNIA. 197 



May. Of T. j^rolixus 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. — S. fulvus, San Bernardino County. 



Paragoges. — P. maculatus is an uncommon insect

Micromastus. — M. gracilis, San Francisco. 



Tyloderma. — T. morbillosum, San Francisco. 



Zascelis. — Z. irroraia, "Cal., Nev., Col."

 taken by sweeping weeds along the Colorado River at 

 Yuma, and a single specimen from Ensenada, Lower 

 California. C. adspersuus 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
