THE CANADIAN ENTOMOLOGIST. 153 



Vol. XXV., 1902, Dr. Dyar published the following description of the 

 larva of the form f -pallida: " Head shining black ; epistoma and 

 bases of antennae pale; width 2.7 mm. Body brown-black, the abdominal 

 feet pale reddish. A broad, distinct, sharp dorsal line, narrowed between 

 warts i., cream-white, pinkish shaded in the incisures. Warts black, hair 

 bristly, sparsely barbuled ; i. small, less than one-third the size of ii., i. 

 with small, ii. with large shining base, normal. Hair all black, even the 

 subventral, longer on joints 12 and 13." 



Distribution. — Toronto, Ont. (Gibson); Meech Lake, Que., May 31 

 (Young); Aylmer, Que., June 5 (Young). 



18. Nais. — This is a very variable species and one which is 

 constantly being mixed up with phalerata. Dr. Seifert has recently 

 published an article on the species in the Journal of the New York 

 Entomological Society, March, 1902, and the plate accompanying his 

 paper gives an excellent idea of the extent of variation in the moths of 

 this Arctian. Through the kindness of Dr. Seifert in sending us eggs, we 

 were able, the past season, to rear a good number of the imagoes. The 

 larvje also vary considerably and we cannot find any character whereby 

 to distinguish them from the larvae oi phalerata. 



Distribution. — Springfield-on-Credit, Ont. (Bethune) ; Kingsville, 

 Ont., Sept. 9 (C. T. Hills); Hamilton, Ont. (Evans); Montreal, Que., 

 July 7 (Stevenson). These records are included on the authority of the 

 collectors themselves. We have not examined the specimens. 



19. ViTTATA. — This species, while it has often been collected, in 

 different localities, cannot be considered a common insect in Canada. 

 The moths are closely related to nais and phalerata, and a series will 

 show considerable variation. A single specimen was bred at Ottawa in 

 1900 from a larva collected in a wood on the 26th May. The following 

 description was taken from the cast skin and head : Head black ; skin 

 of body velvety black, tubercles black, rough, not polished, each bearing 

 a bunch of bright rust-red bristles, those on the dorsum being slightly 

 darker ; none black. Bristles smooth, not barbed ; tubercle i. about 

 one-fifth the size of ii. Thoracic feet blackish-brown. 



Distribution — Hamilton, Ont. (Moffat, Evans); St. Catharines, Ont. 

 (Beadle) ; Toronto, Ont., June (Metcalfe, Gibson) ; Cobourg, Ont., 

 August (Bethune); Ottawa, bred, June 11 (Gibson); Montreal, Que. 

 (Brainerd).
