I OVITATES ZOOLOGICAE XXIII. 1916. 179 



Thorax and abdomen concolorons with wings, abdomen dotted or strigulated with 

 fuscous dorsally and with paired blackish spots (almost or quite connected into 

 belts) at the ends of the segments. 



Shape and aspect of emberizata Guen., but larger. Forewing rather more 



uniformly dull olivaceous, generally without reddish admixture, median band 

 broader, at least at hindmargin, its proximal edge more sinuous, the two lobes at 



its distal margin more equal, distal area generally confusedly marked. Hindwing 



rather more greyish, often darkened at distal margin. 



Underside dirty yellowish white, forewing with fuscous cell-spot, postmedian 

 band from costa, joining a fuscous cloud which runs behind cell from R 3 to M 2 , in 

 varying extent and strength distally, but generally continuing narrowly in front of 

 M 2 as far as termen ; an apical cloud from costa to R 3 , leaving the extreme apex 

 clear, often a line connecting the proximal edge of this cloud with the posterior 

 one. Hindwing beneath with cell-spot, very feeble greyish cloudings and usually 

 rather narrow dark marginal band. 



Sapucay, Paraguay (W. Foster), a long series in coll. L. B. Prout (including 

 the type) and coll. Brit. Mus. ; mostly from end of August to beginning of October, 

 a few in November and December. 



62. Rhopalista hypochrysa sp. nov. 



6, 34 mm. Shape and structure essentially as in viridifusata Walk. (= gaza- 

 pina Dogn. = albidivi&a Warr.), palpus perhaps slightly shorter, abdominal crests 

 less developed. Head and body mostly ochreous, tegula blackish-spotted. Legs in 

 part (especially on the tarsi) infuscated, with the ends of the joints remaining pale. 

 Forewing with proximal area mostly occupied by olivaceous basal and subbasal 

 bands, the narrow interspace whitish ; both with some blackish marking at costa 

 and hindmargin ; median band moderate, olivaceous, from fold to hindmargin black, 

 the olivaceous part appearing rippled with indeterminate lines, which become 

 distinct and black (four in number) at costa ; proximal boundary of band concave, 

 marked by a white line, which is slightly dentate on the veins ; distal boundary 

 augalated outward at R 3 , slightly concave before and more deeply behind the 

 angle, terminating at hindmargin near tornus ; cell-spot black, somewhat elongate ; 

 pale band beyond the median area somewhat lunulate-dentate, double, whiter 

 proximally than distally, divided by an olivaceous line ; area between this band and 

 the subterminal line reddish-brown ; subterminal line whitish, lunulate-dentate, 

 ending at tornus, the deepest tooth on SC 5 ; distal margin olivaceous, paler behind 

 R 3 , some dark marking at apex and between radials ; terminal black dots strong, 

 in pairs at the vein-ends, but slightly connected by a fine blackish line ; fringe 



spotted with blackish opposite the veins. Hindwing golden yellow, with grey 



suffusions basally and along abdominal margin, becoming blackish on the marginal 

 fold ; terminal dots and fringe spots obsolete anteriorly. 



Both wings beneath golden yellow, forewing with a large, hindwing with a 

 small black cell-spot ; forewing with some faint greyish median suffusions, strongest 

 at hindmargin, and with a black distal border from costa nearly to tornus, com- 

 mencing nearly 4 mm. wide at costa and leaving free a small white apical spot, 

 narrowing gradually to R 3 , where it is 2 mm. wide, scarcely widening again pos- 

 teriorly ; hindwing with a much narrower and more incomplete border, not reaching 

 costa and only strong between the radials ; folded area and the contained hair- 

 pencil whitish.
