THE CANADIAN ENTOMOLOGIST, 113 



In our rather extended observations on the species we have 

 everywhere found it associated with Humidus hipiilus, where 

 conditions were at all favorable for the species to gain a foothold, 

 and we wish to propose as a name: 



Papaipema huniuli, n. sp. 



Ground colour a rather even brick-red brown. Head and 

 thorax shaded purplish, the base of the antenna encircled by a 

 cluster of white scales; the tufts on thorax and abdomen specially 

 prominent in both sexes, the anterior one above collar wide-tipped 

 and spreading. Fore wing almost without contrasts, excepting 

 the white stigmata; basal area concolorous, median field similar, 

 the postmedial area narrow, tinted purplish, a yellow shading 

 near apex; antemedial line indistinct, postmedial line double, 

 curving out broadly past reniform, subterminal, faint and very 

 irregular; a conspicuous white scale at extreme base of wing, also 

 along the costa above the stigmata and near the tip, several whitish 

 dots occur; the orbicular and claviform are brightly white, super- 

 imposed as usual, the central spot much the smaller; reniform 

 narrow, but made up of broken pure white spots collected around 

 the central, yellow, lunulate line; fringes purplish dentate. Hind 

 wings paler, silken, yellowish rufous with dull purplish shading 

 at the terminal area, above which a medial line is indicated. The 

 abdomen is of similar hue. Expanse 30 to 38 mm. The male 

 genitalia are generically typical and show little individuality; the 

 trigonate costa is not deeply indented on the outer margin, the 

 anal angle much produced and at a right angle with the axis of the 

 valva; the clasper proportionately large and heavily toothed. 



Habitat: Eastern United States, southeastern Canada; New 

 Brighton, Pa., Wilmington, Del., West Chester Co., N. Y.; Cart- 

 wright, Manitoba; type locality. Rye, New York. 



Thirty bred specimens are at hand, the type with the author, 

 paratypes will be placed in the United States National and the 

 British Museums and in other American collections, rectifying as 

 far as possible the wrong determination of the species as dissemin- 

 ated from Rye. 



The species seems closest superficially to marginidens Gn.,
