C. cassiae was not available for study, but the specimen upon which 

 the original description of P. rebeli was based was examined. This 

 pupa possessed two very minute anal hooks of unequal lengths. 

 Very likely the relative development of these small protrusions may 

 vary; perhaps the specimen of C. cassiae that Koehler (1939) described 

 represented such a variation. The present author currently believes 

 that C. cassiae and P. rebeli are synonymous. 



For similar reasons Prochalia rugosa also has been synonymized 

 under Curtorama cassiae. The differences of the larval cases and the 

 pygidia of the female pupae between P. rugosa and C. cassiae are 

 too insignificant to be of specific importance.

12. Astala, new genus 



Eurukutturus, Eurycyttarus, Manatha, Pachythelia, Platoeceticus, and Psyche, 

 in part, of authors. 



Type of genus. — Psyche confederata Grote and Robinson, 1868. 



Male. — Body and wings usually various shades of fuscous. An- 

 tennae (fig. 375) broadly bipectinate; pectinations gradually de- 

 creasing in length toward tip, arising from middle or slightly above 

 middle of each segment; sensory hairs erect, very fine, 3-5x diameter 

 of pectinations in length. Vesture of thorax variable; wooly or less 

 so. Legs (fig. 178) without epiphysis or tibial spurs. Forelegs 

 greatest in length; first tarsal segment of forelegs longest, longer than 

 that of second pair of legs. End of abdomen slightly surpassing 

 hindmargin of secondaries. 



Wings (fig. 160) uniformly scaled except in A. hqffmanni. Fore- 

 wings 11-veined; apex slightly acute or moderately rounded; discal 

 scales broad or extremely slender, hairlike; if hairlike, majority 

 with bidentate tips; E,3 and 4 stalked, R5 most frequently separate; 

 in both wings Mi absent, M2 and Mg usually separate, base of medius 

 undivided in cell (in one specimen of A. confederata intercalary cell 

 present) ; base of lA vestigial, becoming prominent at point where it 

 bends abruptly down to join 2A, occasionally short spur continuing 

 toward outer margin; 2A angulate at juncture of lA; 2A and 3 A 

 separate at base, fusing for some distance, finally forking again, 3 A 

 continuing down toward hindmargin as short spur. Secondaries 

 7-veined; 8+ M Rj and Rs connected by crossvein; M2 and 3 some- 

 times shortly stalked.
