Dyar in 1902. but is a distinct species, a very excellent fiis;-ure of which 

 is given in Packard's Monograph, Plate IX., Fig. 75. 



Sciagraphia meadiaria Pack., taken by Mr. W. Newcomb at Chil- 

 cotiii in June, 1914. Thi.s one was rather damaged, but we are glad to 

 have the record of it. This group sadly needs revising, hut unfortunately 

 (jur material in this group is very limited. 



Macaria praeatomata Haw. This prett)' species was taken by Mr. 

 Downes at Armstrong in 1915. It is accurately figured by Packard in 

 his Monograph on Plate X.. Fig. 18. The name will probably fall 

 before bicolorata Fab., as I believe the two species are the same. Packard 

 had never seen a specimen of bicolorata, which was described from \'ir- 

 ginia in 1794. Praeatomata, vi'hile not common, is widely distributed 

 throughout the New England States. 



Diastictis decorata Hulst. A specimen of this species was taken 

 by Mr. Anderson at Lillooet in July, 1916. This species was described 

 from specimens taken by Dr. Barnes at Platte Canyon, Colorado, in 

 1896. 



Alois sulphuraria var. baltearia Hulst. This pretty variety was 

 taken by Mr. Downes in June, 1915, and also by Mr. Anderson at Lillooet, 

 27th June, 1916. I have specimens exactly like this one, taken at San 

 Diego, Cal., in July. 



This concludes the list of those that we are absolutely certain of as 

 being new to British Columbia, although there are a few more yet to be 

 correctly placed. We seem to have quite a number of intermediate 

 forms in this Province, perhaps it would be better to say local races, and 

 until these are bred and their life histories worked out, it cannot be 

 definitely ascertained what their relationships are to closely allied 

 species, appearing in other parts of the country. 



Author's Note (July, 1918). — Since the above paper was written, 

 many new facts have come to hand which makes it necessary to add the 

 following notes and remarks : 



Nomenia obsoleta Swett. On looking over the collection of Mr. 

 G. O. Day, of Duncan, in September, 1917, I found that he had four 

 specimens of this species amongst his material, all taken in the Duncan 

 district. Showing how rare this species is, not more than one specimen 

 was taken in any one y.ear, the dates of capture being March 20th, 1914; 

 x\pril 16th, 1915; May 7th, 1916; and April 3rd, 1917. I was extremely 

 glad to get these records, as I had feared that the species was extinct. 



Xanthorhoe defensaria form thanataria Swett, and Xanthorhoe 

 defensaria form suppuraria Swett. These two forms have both l)een 

 placed in the synonymy by Messrs. Barnes and McDunnough in their 

 New Check List. In the case of thanataria they are probably correct, 

 as in my opinion it is only a partial third brood which is produced in 

 those season's having a long, dry fall. The food plant at that time of 

 the year being much less succulent, thus producing a small stunted form
