rmago.—2 S . — Body, wings, and legs uniformly dark gray with a lilac tinge, nearly of the 

 hue of C. regal is between the orange-colored veins of that species. No yellow or orange marks; 

 thorax and abdomen with no yellow or orange spots; head as in C. regalis; s antenna- with 17 

 pairs of double pectinations, C. rt'galis having two more pairs (19); palpi large and stout, a little 

 more so than in C. regal h and asteca. 



Fore wings with two pale pink spots at the base, one just l)ehind the base of the median vein; 

 the other behind the origin of the vein at the base of the wing next to the pink patch on the body 

 at the insertion of the hind wings. (PI. LVIII, figs. 4, 4«.) A moderately large dusky discal 

 spot centered by an irregular crescent-shaped orange-red mark. No other markings. 



Hind wings pale pink on the basal half or two-thirds of the wing, and the pink area incloses 

 the discal discoloration, which is smaller than on the fore wings. 



Under side of the fore wings pink from the base along the middle to the discal spot: the 

 veins are as above, but a little paler, and more lilac. The fore legs are not spined; the fore 

 tibial epiphysis differs in shape from that of C. regalis, being a little longer and less acute. 

 (PI. XXXVI, fig. 23, 23a.) Hind $ tibiic with a stout spine on the inside, the outer one ves- 

 tigial. They are a little larger than in C. r.-gaHs. The genitalia (PI. LX, fig. 3, 3^/, 3/^) ditter
