 rust red with the b;is;il half clotlied with wliiic scales interspersed 

 with a few black ones. Thorax above, and i)atagia dark gray with 

 brown and green reflection. Abdomen animlated wi th brown and light 

 gray ; the brown predominating above, the light gray Ijeneath. Fore 

 wings light gray marked with brown and Idaek. A light band ex- 

 tends across the outer part of the basal third of the wing ; tlie costal 

 half of this l)and is wide, reaching nearly to the base of the wings ; 

 the remaining half is narrow. Xear the ))asc of the wings there is 

 a short transverse gray baud which is sometimes obsolete ; exterior 

 to this is a short longitudinal Idack si)ot.Avhich also varies greatly in 

 size and intensity of color. The light band which extends across the 

 outer part of the basal third of the wing is bordered externally by 

 a dark band, which is narrow on the costal and near the middle of 

 the wing widens so as to reach the outer third of the wing. There 

 are two black discal spots which are sometimes distinct but more 

 often united so as to form a single crescent shaped spot o])ening 

 outward. Tiie markings of the outer third of the wing resemble 

 greatly those of Acrobattis nehuJo, there being a row of six or seven 

 dark spots on the onter margin, and one fourth of the distance to 

 the body a wavy light gray band parallel to the exterior nuirgin, 

 and ])ordered on each side with dark brown; the costal end of the 

 outer of these brown borders is usually darker and widened exter- 

 nally forming a conspicnous black triangular spot. Lower surface of 

 the front wings dark gray especially toward the apex, with a faint 

 brassv tinge. Hind wings light gray with the apex clouded.
