Diagnosis. — The presence of a well-developed digitate medial 

 process on the gnathos serves to delimit this species from among 

 those of the genus with similar wing venation. 



Description. — Frons conical, varying b^o^vn to Ught pink; labial 

 palpi mth basal segments white, outer sides of second and third 

 segments varying brown to light pink, inner sides with white-tipped 

 scales; maxillary palpi approaching frons, brownish white; antennae 

 light brown, laminate in male; occiput broAvn, vertex white behind 

 antennae, patagia and tegulae varying grayish red to brown, legs 

 grayish red to brown on outer sides, white on inner sides. 



Forewings mth extremely variable maculation; area anterior to 

 cell red, brown, white, or mixtures of scales of these colors; cell usually 

 red or white, brown in some (Mississippi) specimens, often a mixture 

 of these three colors; area posterior to cell usually red, sometimes 

 brown; veins traced with white, tracing variable, sometimes absent; 

 10 veins, R2 stalked with R3+4; M2+3 fused, from lower outer angle. 

 Hindmngs light brown, darker in apical area; 7 veins; M3 and Cur 

 long stalked. 



Male genitalia with gnathos bearing apical digitate process. Juxta 

 V-shaped. Vinculum with anterior margin flat and flanged. Valvae 

 mth costa sparsely setose, bearing blunt apical tooth; sacculus with 

 fine hairs. Aedeagus with vesica bearing single subserrate cornutus. 



Female genitaha with ovipositor finely setose on caudal margin, 

 moderately setose laterally. Apophyses curved, posterior curving 

 upward at base and tapering to point, anterior shghtly thickened 

 at base.
