Papaipema plaeida n. sp. 



Head smooth on frons, antenna simple, ringed at base by white scales. 

 The thoracic vestiture is normal in tuftings and density, dull yellowish inter- 

 mixed with purple-brown; abdomen paler, lustrous luteous. Fore wing- in 

 outline rather more falcate below apex than usual; basal area defined in the 

 dull yellow ground color, basal line double; median field evenly defined in 

 dull yellow except above median vein inward from reinform, where a powder- 

 ing of purple brown occurs; the orbicular and claviform show as three super- 

 imposed white spots, the middle one being a mere dot ; the reniform is broken 

 into dots by the veins, clustered about the central lunulate line, and all pure 

 white except the middle outer one, which is yellow ; the median shade line is 

 prominently marked in brown from reniform to inner margin ; post-medial 

 line is double and bends outward with pronounced sweep past reniform; sub- 

 terminal area dull purplish ; terminal space scarcely differentiated in paler shade ; 

 the usual apical dash is of the ground colour. Hind wing much paler, of a 

 luteous shade of the ground color of fore wing, with the veins, a discoidal 

 spot, a median line and a subterminal band marked in brown powderings. 

 On the under surface the wings are glistening luteous, a median line observ- 

 able and brown powderings which are deepest at the costal margins. 



Expanse 31 mm. 



The male genitalic structure is of the conventional pattern of the genus. 

 In minor degree, a narrowing of the valva immediately behind the costa is 

 noteworthy in being more pronounced than with any other species. The 

 usual curved, and sharp-pointed harpe has its outward edge finely toothed. 

 The unique male type is with the writer and was taken at New- Brighton, Pa., 

 (F. A. Merrick), September 6, 1907. This single example is in good condition, 

 and unless a dwarf, indicates a small species of a coloration similar to ditovata, 

 or to occasional specimens of harrisii. From the latter and from asfiita, it differs 

 in the greater curve of the post-medial line. 



NOTES ON A COLLECTION OF LABRADOR LEPIDOPTERA. 



BY J. MCDUNNOUGH, PH. D.* 

 Entomolosical Branch. Ottawa. 

 Through the kindness of Dr. E. M. Walker, of Toronto, a very inter- 

 esting lot of Labrador Lepidoptera, collected in the vicinity of Hopedale, and a 

 much smaller lot, taken at Nain, has passed through my hands for identification. 

 Due to the long series of several species I have been enabled to clear up some 

 doubtful points of synonymy and append herewith a list of the species collectevl 

 with notes on certain of them. Where no definite locality is mentioned it is 

 understood that the species were captured at Hopedale.

I have already on two occasions discussed the status of this race (B. &
