Harriman Expedition.—Prince William Sound, at Fox Island (Kin- 
caid) and Virgin Bay (Coe). This is the most northern locality known 
for this species. 
Distribution.— Prince William Sound; Kasaan Bay, Prince of Wales 
Island, Alaska (U.S. Nat. Mus.); Vancouver Island, British Columbia 
to Monterey, California (type locality of Xanthodes hemphillit Locking- 
ton). Lower California (A. Milne Edwards). 
The figure given by A. Milne Edwards resembles Z. de//us more than 
it does any of the other species here described; the locality given is 
Lower California. 
There are on the Pacific coast six closely allied species of Lophopano- 
peus ; some of these have been confused with LZ. de//us and L. leucomanus ; 
therefore the published localities from which I have not examined speci- 
mens are accepted with a reservation. 
1 I have concluded to omit Daiva americana Stimpson from the list until it is known 
that the species really occurs in California in contradistinction to Lower California.
