154 THE CANADIAN ENTOMOLOGIST. 



20. Phalerata. — The life-history of this Arclian was published by 

 the writer in the Canadian Entomologist, Vol. XXXIL, p. 369, and 

 in the February (1902) number of the same journal further additional 

 notes were given. On the whole, the moths of phalerata are fairly 

 constant. In those which we reared in 1900, there was a remarkable 

 lack of variation ; but in some of those bred the following year the W 

 mark on the primaries was indistinct, and in a few (females) nearly 

 obsolete. In none of our specimens, however, is the W mark altogether 

 absent, as is often the case in nais. In all the specimens of nais which 

 we have reared, the costal edge of the primaries is black, and this 

 character has been referred to in several accounts of that species. In 

 phalerata., however, the costal edge of the primaries is yellow in some 

 specimens and black in others, in the same brood. On the accompany- 

 ing plate two females and two males are figured, one female with a black 

 costa, the other with a yellow costa, and the same with the males. The 

 larvee of phalerata vary chiefly in the colour of the bristles ; in most of 

 our specimens these were black dorsally and rust-red subventrally. Some 

 larvae had bristles of a decidedly pale grayish colour, other specimens had 

 these more of a yellowish tinge, while still other examples had nearly all 

 the bristles of a pale rust-red colour. A dorsal stripe, or a series of 

 elongated spots, was present in some specimens, while others had no 

 niarkings whatever on the body. 



Distribution. — This species doubtless occurs in various districts in 

 eastern Canada, but the only Canadian specimens examined and 

 identified by Dr. Dyar were collected at Toronto, Ont., by the writer. 



In conclusion, I beg gratefully to acknowledge much assistance in the 

 preparation of this paper from my kind and ever-helpful teacher. Dr. 

 James Fletcher. The writer is also under much obligation to Dr. Dyar 

 for help, and to his many friends who have sent him material to study 

 and specimens to examine, as well as records of species in their 

 collections. My thanks are also due to Dr. Charles Saunders who took 

 the photograph from which the accompanying plate was made. We shall 

 be very glad indeed at all times to corresi)ond with any one interested in 

 these Arctians, and shall, of course, be most happy to receive for study, 

 eggs or larva; of any species of the genus. Material of the commonest 

 kind will be gladly welcomed.
