( 181 ) 



cell-spot near beyond second line ; outer line at five-sisths, parallel to hindmargin, 

 yellowish white finely edged on both sides with black and again with a pale black- 

 edged line ; onter half of central fascia with several darker olive waved lines ; sub- 

 marginal line formed of white-edged dark lunules ; fringe concolorous. 



Ilindwings : similar, the spaces between the dark lines paler. 



Underside cinereous olive, with a rufous tinge along the disc of forewings ; the 

 hindwings paler. Head, thorax, and abdomen olivaceous cinereous. 



Expanse of wings : 24 mm. 



One ? from Azalar de Carthago, Costa Rica, 5000 to 6000 ft. (Underwood). 



The hindmargin of both wings is simply bulged, not angled, below the middle. 



151. Polyphasia truncata rufibrunnea snbsp. nov. 



This South American form is distinguished by the fasciae before and after the 

 central area being reddish brown, this tint also extending to the basal area, and in 

 one of the two examples being also diffused over the whole wing, of which in the 

 other example the central area is whitish; all the shades are more precise above the 

 subcostal and below the submedian vein. 



Hindwings : shining whitish grey. 



Two ? ? from Parana, Entre Rios, Argentina, of 32 mm. expanse. 



152. Psaliodes infantula, sp. nov. 



Forcivings : dull lilac, crossed by three pale green lines ; the first at one-fourth, 

 its outer edge concave ; second shortly beyond first ; third from two-thirds of costa 

 to three-fourths of inner margin, sinuous, and inbent below median ; joined above 

 the middle by an oblique green streak from the apex. 



Hindwings : pale grey. 



Underside darker, and freckled ; the markings of the forewings showing 

 through ; the hindwings with traces of lines along inner margin. Head damaged ; 

 thorax and abdomen cinereous. 



Expanse of wings : 16 mm. 



One (? from above Chimbo, Ecuador, 30U0 ft., August 1897 (Rosenberg). 



The single specimen is not in good condition ; but its size and coloration 

 distinguish it well from other species of the genus. 



Ptychorrhoe gen. nov. 



Forewings : triangular ; costa straight, but strongly convex before apex ; 

 hindmargin oblique, faintly elbowed at vein 4, but not curved, as long as inner 

 margin, which is somewhat convex. 



Hindwings : narrow ; a slight prominence at vein 7 and a strong tooth at 

 vein 6, thence sabcrenulate to the apparent anal angle, the abdominal margin 

 below vein 2 being folded under as a flap. 



Antennae simple, filiform ; palpi porrect, the terminal joint drooping. 



JS'euration : forewing, cell nearly half of wing ; discocellular concave, oblique 

 below ; first median nervule at one-half, second close before end ; 7, 8, 9 stalked ; 

 10 anastomosing with 11 far back, and again with 8, 9, forming a double areole ; 

 hindwiug with discocellular oblique, and radial from the centre ; 6 and 7 stalked.
