185. Cymatophora ochrea sp. nov. 



Forewings : 3elIowisli claj-colonr, speckled with dark fuscous ; a diffuse curved 

 fuscous basal shade at oue-fourth ; a broad diiFase nearly straight dark fuscous 

 median shade, followed b}' a thick dentate-edged postmediau line, which joins the 

 median shade on inner margin, and projects slightly along veins 3 and 4 ; the band 

 between this line and the submarginal is paler, less speckled with fuscous ; sub- 

 marginal line fine, but blotched on costa, beyond cell, and at inner margin ; the 

 blotch beyond cell connected with hindmargin by a triangular iliffuse fuscous patch ; 

 marginal spots dark fuscous ; fringe concolorous ; cell-spot dark fuscous, lost in the 

 median shade. 



Hindwings : with two dull fuscous lines, median and postmedian, near together ; 

 a less distinct dark submarginal line. 



Underside similar, but all the tints duller. Thorax and abdomen like wings ; 

 face, vertex, and collar yellower. 



Expanse of wings : 3U mm. 



One c? from Chiriqui, Panama. 



The hindmargin of hindwings is slightly and irregularly indented beyond cell. 

 The forewings have no fovea, but it may be left in C ijiwxtophorn provisionally. 



186. Cymatophora paraphiata sp. nov. 



Forewings : pale grey, more or less suffused with dull tawny, speckled and 

 striated with fuscous ; the lines fuscous, irregularly waved ; first at one-fifth, 

 second at two-fifths, both obscure, slightly bent out in cell ; outer line more distinct, 

 denticulate outwards on the veins, and somewhat projecting between veins G and 3 ; 

 submarginal indistinct, pale, preceded and followed by dark striae partially confluent 

 into clouds ; fringe grey with dark spots at base between tlic veins ; cell-spot grej', 

 indistinct ; a fulvous cloud below costa beyond the outer line ; a diffuse pale space 

 at apex and anal angle. 



Hindwings : with the extreme base pale, the lines as in forewings, the dark 

 dusting stronger beyond first line ; area beyond submarginal line paler, without the 

 tawny suffusion of the central area. 



Underside whiter, the speckling coarser ; marginal third much darker, fulvons 

 and fuscous, less marked in the hindwings ; cell-spots blackish, distinct. Head, 

 thorax, and abdomen like wings. 



Expanse of wings : 43 mm. 



One ? from British Guiana. 



The reference to Cymatophora is provisional. The hindmargin of both wings 

 is subcrenulate. The nenration is somewhat abnormal, the cell being only one-third 

 as long as wing ; veins 3 and 4 from the lower end of cell ; the lower radial from 

 above the middle of discocellular ; 7, 8, 9 stalked, 10 and 11 free. The costa of 

 forewings is rather prominently arched near base and incurved at middle. 



187. Cymatophora ustifumosa. 



Bri/optera (?) ustifumosa Warr. Nov. Zoul. IV. p. 466 ? . 



Having lately seen twelve sj)ecimens (six SS, six ??)of this insect from 

 Parana, Entre Kios, Argentina, I can refer it ;to the genus (ywa^oyV/orrt, and describe 

 the 6, which differs very considerably from the ?, having the hindwings white, 

 while those of the ? are smoky fuscous.
