Larva unknown. 



Mr. Henry Edwards says of this species : " It is found in rather high regions. 

 I have seen it most abundant at Virginia City, where it flies in the mountain 

 canons, as llutulus does in those of the valley. I have also taken it on the coast 

 range in Napi County, and near Mt. Diable, and have some beautiful specimens 

 which I found at the Dalles, Oregon. I did not see it in Vancouver. It may be 

 regarded as one of our rarities." 



Drnmus has been brought from Southern Utah and Arizona by Lieutenant 

 Wheeler's expeditions, and from Montana Ijy those of Dr. Hayden. According 

 to Mr. Ridings, the specimen described by him was taken in Kansas.
