Hyphoraia festiva Bork. 



Bombyx festiva Bork.: Eur. Schmett., Ill, p. 191 (1790), nee. Hufn. 

 Bombyx lapponica Thunb.: Diss. Ent., pt. II, p. 40, f. 7 (1791). 



Four specimens of this rare species from the following localities: 

 Bernard harbour, Northwest Territories, July 9, 24, 1915, July 3, 1916, 2 males, 

 1 female (F. Johansen) ; Port Epworth, Coronation gulf, Northwest Territories, 

 July 15, 1915, 1 male (J. J. O'Neill). The specimen obtained on July 24, 1915, 

 was reared. (Breeding record 68.) 



These specimens resemble rather closely the figure of the species which is 

 given in Seitz's Macrolepidoptera of the World. 1 As is to be expected among 

 arctlid moths the markings are variable. Such variation is indicated in the 

 two male specimens figured on PL V, figs. 19 and 20. The abdomen of the 

 female is much redder than that of the male as is also the underside of the 

 wings. The antennae of the males are distinctly pectinate similar to the males 

 of //. parthenos Harr. 



On July 7, 1915, Mr. Johansen found the cocoon of the moth which emerged 

 on July 24, attached to a stone near a river bed at Bernard harbour, Northwest 

 Territories. His notes indicate that the pupa was 20 mm. long, smooth and 

 black. The resultant moth a female, was kept alive. Mr. Johansen's notes 

 read : 



"August 8 Imago still living. During the last few days she laid about 

 one dozen pale-green eggs (1 mm. in diameter) on different places in the jar. 



"August 16 Imago dying. She has now laid seventy eggs all told." 



The cocoon is thin, pale yellowish-white, oval, 25 mm. long, 14 mm. wide; 

 the pupa and cast larval skin are plainly observable through the cocoon. 



The following notes on the larva have been made from the cast skin removed 

 from the cocoon: 



Head 3 mm. wide, rounded, black, polished, mouth parts reddish. Body 

 black, tubercles large, each bearing a bunch of spreading, rather long hairs, 

 slightly spinulose, those from the dorsum being mostly of a sordid whitish 

 colour with black and dark brown hairs intermixed, while those from the lower 

 lateral and ventral areas are darker, being black or dark brown. Thoracic feet 

 black, red tipped, shiny; prolegs also black, shiny, crotchets mostly reddish. 



PUPA. Length 18 mm., width at widest part 6-5 mm., polished, anterior 

 half of abdominal segments slightly pitted and with short setae; posterior half 

 smooth, as in Hyphoraia alpina Quens. Wing-cases and thorax slightly wrinkled. 

 Cremaster different from this latter species being shaped as shown on PL III 

 at fig. 11, and bearing about forty stout capitate dull reddish bristles. 



Seit/ 2 refers to the larva as being dark grey with small black head and 

 long black or foxy red hair. The food plant is given as Vaccinium uliginosum 

 and other bog plants. 



In addition to the above specimens there is in the Ottawa collection a female 

 bearing the label " Hudson bay, Dr. Bell," which we associate with this' species. 



Genus Apantesis Wlk. 

 Apantesis quenseli Payk. 



Hombyx quenselii Payk.: Skriv. of Nat. Selsk., II, 99, 1793. 



In the Entomological Record for 1915 3 I recorded this species from 141st 

 meridian, north of mount Natazht, 6,500 feet, July 1, 1913 (E. W. Nesham). 

 This specimen, a female, is in the Canadian National collection.
