SUBGENUS GRAMMIA RAMBUR
Diagnosis: All but two of the 36 species of the genus are included in the subgenus Grammia . Although the wing pattern is superficially like Mimarctia , the forewing costal cell is never entirely pale-scaled, and the costal portion of the postmedial band is not angled sharply basad. Structurally, the dorsal margin of the male juxta is broadly concave and u-shaped (somewhat v-shaped in Mimarctia ). The male vesica is moderately developed with poorly to moderately differentiated chambers and diverticula ( Figs 44–71 View Figures 40–45 View Figures 46–51 View Figures 52–57 View Figures 58–63 View Figures 64–68 View Figures 69–71 ); Mimarctia exhibits large, well-defined chambers and diverticula ( Figs 40, 41 View Figures 40–45 ). The male distal portion of valve is well developed, simple, and rounded to slightly pointed (rounded or sickle-shaped in Mimarctia ). The female ductus bursae has two sclerotized lateral plates near the ostium, absent in Mimarctia . Where known, the cremaster of the pupa is short and broad, not elongate as in Mimarctia , and lacks the basal folds or grooves (except for G. virgo ) of Mimarctia ( Smith, 1938a, b). The larval tubercles are shiny silvery-white not dull as in Mimarctia , with coarsely barbed (vs. finely barbed) setae ( Smith, 1938a).
