THE CANADIAN ENTOMOLOGIST 403 



The Moth. — The moth is a rather striking species. With the 

 wings spread it measures from about 37 to 45 mm. in width. The 

 fore wings of the male are dark purpHsh brown shaded along the 

 lower edge, and in the space about midway between the reniform 

 and outer edge with dull red. The costal area is similarly coloured. 

 In the female all such areas are of a grayish-white colour. The 

 orbicular and reniform spots are conspicuous in both sexes, being 

 whitish with brown centre. A pale, apical spot is also present, 

 as well as a short, pale dash adjoining the dark claviform. The 

 transverse lines are pale. The hind wings in both sexes are whitish 

 tinged with brown. The moth is figured by Hampson, Plate 

 LXVI, 8 (Lep. B.M., Vol. IV). 



Natural Enemies. 



From the larvae received in 1916 we reared at Ottawa several 

 specimens of ichneumonid parasites of two species, namely, 

 Amblyteles suhfuscus Cress., and Amblyteles nuncius Cress.,* both 

 species of which emerged in August. 



In addition to these parasites an important percentage of the 

 larvae were destroyed by the fungus known as Sorosporella uvella, 

 the disease being so determined by Dr. Roland Thaxter. 



Control. 



At the time of Mr. Wilson's visit to Sechelt at the end of 

 May the efficacy of the well-known poisoned bran remedy was 

 explained and its immediate use was urged. Reporting further 

 under date of June 19, Mr. Wilson stated, "I am glad to report 

 that where my instructions were carried out the cutworms were 

 destroyed to the extent of 95 to 100 per cent. I asked the Sister 

 Superior at the school to have the mixture of bran, Paris green 

 and molasses, applied and to leave a certain number of check row^s 

 without any treatment. The untreated check rows have been 

 eaten as bare as the road, not a vestige of plant life remaining, 

 while the other rows have not lost a plant since the mixture was 

 applied." 



*Both species determined by Mr. W. H. Harrington.
