 Crystal Springs, San Mateo Co., June 25, 1916; Niles Can- 

 yon, September 2, 1916; Walnut Creek, August 10, 1916. 

 Common on willows in the coast region. I have examined 

 a great number of examples from Alameda Co., the type 

 locality for Ball's var. depictus and have seen nothing but the 

 typical form and a deeply colored variety which I describe 

 below : 



211. Idiocerus amoenus pictus, new variety 



Differs from the species in being darker in color; vertex 

 and face above marked with brown and irrorate with pale; 

 pronotum and scutellum chestnut brown; elytra smoky with 

 a broad whitish transverse band across the middle of the 

 clavus followed by a band of deeper chestnut brown; oviduct 

 fuscous-brown. 



This is the most common form of the species throughout 

 the bay region in spring and early summer, later in the sea- 

 son they become paler or mostly revert to the typical form 

 which was the only form I took in San Diego Co. 



Holotype (No. 362), female, from Niles Canyon, in collec- 

 tion of the California Academy of Sciences.
