There appears to be a significant amount of intraspecific variation in the width and shape of the yellow-orange transverse FW band, and in the shape and size of the yellow-orange HW area, all of which contributed to making this a particularly difficult identification problem.    Lyces angulosacan be characterized by its relatively large size (FW length 516.5– 21.5 mm), by having a slightly curved, light yellow to lemon-yellow transverse band in the FW, and by having a mostly rounded central area of the HW(pl. 29). The majority of material in museum collections from Pelotas, Brazil, identified by C. Biezanko as ‘‘  L. vittula’’, a species now in the new genus  Proutiella, is instead  L. angulosa. A female from Teresopolis, Brazil, somewhat further north than the majority of material examined, matches the typeprecisely. Its genitalia ( JSM-1492) are indistinguishable from more southerly females.  Lyces angulosaoccurs exclusively in the Atlantic forests of central and southeastern Brazil. Dissection of the USNM typeof  Ephialtias morenaWarren( JSM-1379), from Rio Grande do Sul, previously regarded as a distinct species ( Bryk, 1930), shows that its male genitalia are identical with those of  L. angulosa. Its wing pattern is also the same. For these reasons I propose  morenaas a new synonym of  L. angulosa. The following is an undescribed  Lycesspecies, perhaps related to  L. angulosa: ³, Brazil, Rio de Janeiro, 7 Aug 1932, leg. P.
