of upper side repeated, with pink shading at base of wing and a broken pink 

 band centrally in the postmedian pale area. Expanse 24 ram. 



Habitat: Paradise, Cochize Co., Ariz, (June, Aug.). 2 $. Types, 

 Coll. Barnes. 



A very striking species, allied to fervifactaria Grt. but differing in 

 the maculation of the secondaries. 



EUSTROMA FASCIATA sp. nOV. (PI. XXI, Fig. 1). 



Primaries with the basal area whitish, sprinkled with brown, crossed by 

 a fine brown rounded basal line and bordered outwardly by a broad deep choc- 

 olate brown band which tends to suffuse over the whole basal area; this band 

 is followed by a broad upright white ante-median band, faintly brown sprinkled, 

 the inner edge of this band is gently rounded at costa and is rather even with- 

 out prominent angles (in the 9 there is a small projection in the cell) the outer 

 edge is regularly dentate and curved slightly inward at costa; median area 

 deep chocolate brown, shaded with pale in costal portion around a small discal 

 dot and crossed by two waved dark lines, parallel above inner margin, diverg- 

 ing in the cell and approaching each other again at costa ; outer border of median 

 space with prominent bulges between veins 2 and 3 and 3 and 4 and a slight 

 inner angle on vein 1 ; subterminal and terminal spaces largely whitish, lightly 

 sprinkled with brown with a fairly evident crenulate pale s. t. line, shaded 

 inwardly with brown which forms a distinct patch at costa; a dark brown 

 subapical patch and a slight oblique apical streak; terminal broken dark line. 

 Secondaries whitish, lightly brown-sprinkled with a fairly evident median dark 

 line bent rather sharply at vein 4 and heaviest above inner margin ; faint traces 

 of a pale s. t. line, shaded inwardly with brown. Beneath pale with the macula- 

 tion of upper side partially showing through, a pale broken s. t. line on primaries 

 and a distinct discal dot on all wings. Expanse 5 34 mm., 9 i7 mm.

The species is allied to mihilata Pack. (Fig. 2) but has the ante- 

 median white band with much more regular edges and less bent in at 

 costa; there is also no trace of yellow shading; various other minor 

 points of distinction are best brought out by our figure ; the 3 geni- 

 talia offer no point of distinction from that of nnbilata as far as we 

 can see; the species should be readily recognized by the contrasting 

 nature of the alternate brown and white bands. 



Dysstroma mulleolata Hist. (PI. XXI, Figs. 7, 8). 



In our notes on truncata and its forms (1917, Contr. Ill (4), 

 227-30) we accepted tentatively Mr. Swett's determination of this forni 

 which we considered a race of truncata but which Mr. Swett treated
