secondaries of a deep russet color; fringes and all maculations of dark 

 purple, strewn with black dots, much like in var. didyma DeB., thus 

 showing an irregular, triangular space of deep russet resting with its base 

 on apical half of costa pointing towards median nervure and bounded by 

 the discal spot and transverse apical arched line respectively. Seconda- 

 ries of a rich russet, with discal spot; mesial undulating band and basal 

 tinge of dark purple; some black dots along marginal area. 



Below: wings and abdomen of a lighter russet shade. Discal spots, 

 space between apical, arched transverse line and external margin of pri- 

 maries of dark purple, fading towards interior margin. The marginal 

 space of secondaries between mesial band and exterior margin of brownish 

 purple. 



Females. The same rich russet as in the males prevails, but only the 

 discal spots, the transverse apical, arched band of primaries, the mesial 

 band oj secondaries and the basal tinges are of dark purple. The mar- 

 ginal spheres in both wings resembling var. didyma, are of a bright 

 chestnut-brown. Below: both wings russet, with light brown marginal 

 sphere, somewhat fading into yellow in basal half of interior margin of 

 primaries. 



This is a remarkable variety from southwestern Texas; con- 

 stant in all its characters, as shown by a number of examples 

 I have lately received.

Citheronia regalis ab. Saengeri. Head, thorax and abdomen bright sul- 

 phur. Primaries grayish purple, with yellow nervures. Basal and discal 

 dots very large and like the transverse intercellular, oval maculations of 

 bright sulphur; apical part of costa and interior margin bright sulphur, 

 fringes equally so at intersection of nervures. Secondaries uniformly 

 bright sulphur, with a slight orange, basal tinge and faint indications of 

 grayish purple transverse maculations in cells near anal angle. 



Below: primaries of bright sulphur, with a slight orange tinge along 

 nervures. Discal spot and marginal space from apex to outer angle, as 

 well as the two upper cells near centre of costa, of grayish purple. Sec- 

 ondaries bright sulphur, with discal spot and mesial band of orange color; 

 apical part of three upper cells of grayish purple. 



Type "J> , coll. B. Neumoegen. 



A wonderful aberration, fresh and bright in appearance, and 

 entirely distinct from the typical form. It was taken in the upper 

 part of New York City by Mr. Herman Saenger, to whose in- 

 dustrious exploits I cannot do more honor than by dedicating 

 this beautiful insect to him. It is an enormously developed , 

 expanding 115 mm., the body having a length of 35 mm.
