Habitat. —Q2,\\{oxmz, (Coll. Dr. Behr.) 



Described from a single specimen raised from a larva found in May 

 in Marin county. t)r. Behr states that the larva bore a striking resem- 

 blance to that of Syntomis and the cocoon to that of Halesidota, but is 

 unable to give the characters of the larva more in detail, as it changed 

 to the pupa immediately after it was found. The anterior wings have 

 the costa and inner margin more parallel, and the apex of the wing 

 more quadrate, than in the other species of the genus.
