in the medial area by white scaling, again present as a dash in anal angle above 

 vein 1, and there underlined with whitish. T. a. line black, lined with pale 

 inwardly, zigzag, slight points on subcosta and radius, produced to a long point 

 in the cell where it nearly reaches to the center of the wing, from thence oblique 

 inwardly to a point on cubitus, again outv/ardly oblique to a point of intersec- 

 tion with the black basal streak in the submedian fold, again outwardly oblique, 

 ending on vein 1, about 4 mm. from body. A short black streak present near 

 base of wing below vein 1, oblique, subparallel to basal part of the t. a. line 

 of which it is probably a part. Another more or less suffused black streak near 

 inner margin, almost connecting t. a. and t. p. lines. T. p. line represented as ?. 

 poorly written black shade, somewhat dentate inwardly between the veins and 

 excurved from the costa to vein 4 (M^), thence inwardly dentate to below sub- 

 median fold, connected with the black streak in the median area. A few sagitate 

 black dashes between the veins, at and near apex, causing an apical shade. The 

 lowest of these dashes is produced into a long dash and crosses the t. p. line 

 between veins 4 and 5 (M^-M^). S. t. line ill defined. Fringe checkered gray 

 and white. Secondaries : almost uniformly deep fuscous, scarcely paler toward 

 the bases. Fringes white, with a checkered fuscous interline. 



Beneath : primaries deep fuscous, slightly paler basally especially in the 

 anal region. A trace of a spot present at the end of the cell. Hair in the cell 

 somewhat deeper in color than the general ground. Secondaries : deep fuscous 

 along the costal regions and around outer margin to near middle of the wings; 

 basally pale. Conspicuous black spots present on the discocellulars connected 

 by bars of the same color thru the cells to the wing bases. 



Sexes : similar ; the male as dark as the female. 



Closely allied to briicei, Sm., but the t. a. and t. p. lines are strong 

 enough to give the species almost the habitus look of a Lathosea. The 

 male antennae are the most heavily pectinate in the genus Rancora, 

 in this way approaching Lathosea. The overhanging cilia of the 

 eyes are not as strong as in Lathosea and the smoother vestiture com- 

 bined with the conspicuous heavy spot and dash on each secondary 

 below places the species in Rancora. The species is placed before 

 strigata, Sm.
