>■-. Polyphasia schistacea s^p. nnv. 



Fomviiigx : whitish, iliisted with <rrc_v aufl tawny scales, theso thickest in basal 

 area, miildle band, and marginal border ; the edgeof tlic basal j)atch and inner edge 

 of central fascia are iioth cnrved and waved, the onter edge from quite two-thirds 

 of costa to five-sixths of inner margin, toothed ontwardlv l)etween the veins, bnt the 

 three centra! teeth not particularl\' jjrominent ; the fascia is edged outwardly by 

 a whitish sj)ace, followed immediately by a dark dentate wavy line parallel to the 

 edge of the fascia itself, beyond which tlie margin is darker, with the snbmarginal 

 line faintly shown ; a dark ()lilii|ne apical sliade : fringe concolorons, darker marked 

 beyond the veins. 



Hinchcings : dnll whitish grey, t1ie basal three-fourths, as far as a crenulate 

 postmedian cnrved line, darker ; triices of a discal dot and a snbtuarginal line. 



Underside ochreons grey, dnsted witli darker grey ; the discal spots and onter 

 lines showing darker on 1ioth wings. Head, tjiorax, and abdomen varied like 

 the wings. 



Expanse of wings : 31 mm. 



One ? from Boulder, ( 'olorado (Osier). 



Tn this species the forewings are more pointed, almost snbfalcate : the hind- 

 margin of the hindwings is distinctly crennlate, and these wings themselves of 

 a different shape from any of the forms of ir/inrnt", being prodnced at apex : the 

 central fascia of forewings is of nearly uniform breadth throughout, and externally 

 reaches nearer the hindmargin. 



S3. Rhopalista semiobliterata, 



Ilammaptcra srmiobliferata Warr., Nov. Zooi.. II. ]i. ll."i. 



I find that this insect belongs to the genus Rhopalista. At tlie time of 

 describing the species I had not differentiated the genus from Ildintmiptera. The 

 tuft of hairs in the furrow on the hindwings above is pinkish ochreous. 



84. Sparg'ania bellipicta sp. nov. 



Forcivinga: whitish; the cross-lines and bands leaden fuscous, slightly 

 greenish-tinged, with nnmerons yellowish scales intermixed ; central fiiscia narrow, 

 its onter edge prominent at vein (J and with two consjiicuous teeth between veins 

 2 and 4, lunulate below ; the usual ]iale band between basal patch and central 

 fascia almost as dark as the patch and fascia, so that the whole basal two-thirds of 

 wing appears dark, crossed [ly the usual darker waved transverse lines ; cell-spot 

 blackish, distinct ; a pale band with a waved threadlike central line beyond the 

 fascia, followed by three similarly waved and dentate lines : the whole apical space 

 as far as vein 4 sufinsed with darker, which beyond the cell forms two deeper, 

 lilackish shades to hindmargin ; pairs of dark marginal dots at the vein-ends ; 

 fringe whitish in the apical half, dark grey in the basal half, with darker quadrate 

 j)atche8 beyond veins. 



Hindwings: uniform pale orange, with a slightly darker marginal line and 

 some dark scales at anal angle ; fringe yellow. 



Underside of both wings dnll brick-red ; the forewings tinged with grey to
