- flight they are almost invisible. The species is rather small, expanding only 11 mm., and the 
wings are very narrow, the fore wings being about 44 mm. broad and the hind wings about 1 mm. 
It is an extremely handsome insect when viewed under a lens, ail the wings being of an 
iridescent purple with a large golden spot on the fore wings about two-thirds out from the base. 
We also took three or four specimens which were unspotted. At first these were thought to be 
a different species, but later on Mr. Busck made slides of the wings and genitalia, which disproved 
-that idea. He considers them to be merely varieties of the typical form. 
This species is interesting from the fact that it is a representative of the family Microptery- 
_ gids, which is the most primitive family of all the Lepidoptera. The fore and hind wings each 
contain twelve veins, and a jugum is developed at the base of the inner margin, which serves 
as a wing-coupling apparatus. This family is very closely allied to the order Trichoptera 
(caddice-flies), and it is from this latter order that the Lepidoptera have undoubtedly evolved.

929. dmilia roscata Wik. Taken by Mr. L. E. Marmont at Maillardville on July 2nd, 1922. 
This is one of the finest captures of the season, as it is the rarest of all our species in this 
family. The specimen illustrated is the first one taken since 1906 that I have any knowledge of. 
In the 1906 Check-list it is recorded from Goldstream and Mission. I have not been able to find 
any trace of the Goldstreum specimen and I know nothing of the one from Mission. In the 
Bull. B.C. Ent. Socy., Sept., 1906, under the heading of “ Notes on the Season of 1906,” it says: 
“Mr. Harvey received from a friend a fine specimen of AJmilia roseata, taken early in July*on | 
the Squamish River.” This record is authentic, as I found the specimen referred to in the 
Harvey collection. 
Noctuide (Plate V.). 
1507. Aplectoides occidens Hamp. This is another very fine record, as very few specimens 
of this species have been taken in the Province. The specimen illustrated was taken’ by the 
Hon. J. G. Colville at Saanichton on August 15th, 1922, and is the first that I have seen siuce 
I discovered a specimen in the Bryant collection which was taken at Wellington on August 4th, 
1902. This latter specimen was labelled “ Wadena mustelina Sm.’ and was listed under that 
name in the 1906 Check-list. I had great difficulty in getting this species determined, as it was 
not represented either in the Canadian National Collection or the U.S. National Museum. Later 
Dr. J. MeDunnough identified it from the co-type in the Wolley Dod collection, which was 
bequeathed to the Dominion Government by the late F. H. Wolley Dod. Dr. MeDunnough also 
informed me that they have a specimen from Ucluelet, which is on the west coast of Vancouver 
Island. In the Entomological Record for 1919 Gibson and Criddle record a specimen of occidens 
taken by Mr. J. B. Wallis at Sicamous, B.C., on August 12th, 1915. I have also recently 
determined a specimen as this species for Mr. A. W. Hanham, taken at Quamichan Lake, V.I., 
on August 23rd, 1918. These five records are the only ones that I know of from this Province. 
1900. Perigrapha algula Sm. ‘Three specimens were taken by Mr. T. A. Moilliet at Vavenby 
on April 30th, 1922. We were glad to get these, as this species was not previously represented 
in our collections. I have seen specimens from Kaslo, where Mr. Cockle takes it oceasionally, 
and Dr. W. R. Buckell also records it from Salmon Arm. 
1901. Perigrapha achsha Dyar. A single specimen of this species was also taken by Mr. 
Moilliet on April 20th. This is a rather rare species, as I have only seen two other specimens 
in British Columbia collections; one was taken in the Penticton District by Mr. FE. M. Anderson 
in 1913, and the other by Mr. G. O. Day at Quamichan Lake, near Dunean. This latter is rather 
an unexpected locality, but I do not think that there is any doubt about the determination, as 
it agrees with the Penticton specimen which was determined for me by Dr. A. W. Lindsey. In 
the Barnes collection at Decatur, Ill., is a specimen from Arrow Lake, B.C., which bas been 
compared with the type, and the Penticton specimen agrees with this. Algula and achsha are 
closely allied and have been somewhat confused in collections, but can be differentiated by the 
fact that achsha is hoary grey powdered, except in the inner part of median and basal areas, 
while algula is evenly coloured and ranges from dark slaty grey to a purplish red. 
2030. Oncocnemis levis Grt. This fine noctuid was captured by Mr. W. B. Anderson at Fort 
Steele on September 16th, 1918, and as far as I am aware has not previously been recorded from
