 This species differs in coloration from C. Ochroscapus, in having 

 the head and patagia crimson instead oi yelloiv, and the costa of the 

 anterior wings prominently white. It is abundant round the Bay of 

 San Francisco, frequenting low marshy places, and in this particular 

 appears to differ widely from C. Ochroscapus, which is a true moun- 

 tain insect. C. Multifaria flies in June and July; is exceedingly slug- 

 gish in its habits, and is frequently found clinging to the stems of 

 grasses and carices, from which it may be easily shaken into the col- 

 lecting net. When worn and faded, the vermillion of the head and 

 epaulettes assumes an orange tint, but never the deep yellow so 

 characteristic of C. Ochroscapus.
