REPORT 
ON THE 
ENTOMOLOGY OF BRITISH COLUMBIA. 
(By W. H. Danby and C. Be Blois Green.) 
It is very pleasing to know that the past year has fully proved British 
Columbia to be a mine of wealth to the Entomologist; but while the Main- 
land has produced many rare species of DIURN ALS, the palm must be 
awarded to Vancouver Island, where new species of the HETEROCERA 
have been found, owing to the untiring energy of members of this Society. 
In two instances new genera rewarded dilligent work, thus showing that 
Vancouver Island, in itself, is a grand field of research. 
A list of captures during 1892, is given as far as possible; but the names of 
species belonging to the GEOMETRINA, cannot be included in this report, 
for the reason that, to get them named by competent authorities takes con- 
siderable time, in consequence of the great care necessary to avoid mistakes. 
Many species have, however, been collected of this family, and their names 
will probably be known soon, when full information will be given the So- 
ciety for the benefit of collectors. Other new species, and probably new 
genera, are expected to be amongst the specimens which have been for- 
warded East for determination, and until they have been authenticated by 
comparison with known types, we must rest satisfied with the result as far 
as known. 
In regard to the DIURN ALS, much good work has been achieved. The 
beautiful Satyrid, CHIONOBAS gigas, which has hitherto been considered 
strictly local in its habitat on Mount Finlayson, being proved to be gener- 
ally common in the Highlands of South Vancouver Island. As far as known, 
CIIIONOBAS gigas is confined to this Island, no account of its capture on 
the Mainland being recorded. 
During 1892, the Vancouver Island oak tree pest, which has for years 
defoliated the oaks around Victoria, was conspicuous by its absence. There 
is no doubt but that the larvae of this insect (ELLOPIA somniaria) were
