outer side is a difficult and not a very satisfactory character. The 

 claw of P. tepperi is quite small and apparently on the inner side. 

 "Polenta" gladiola Barnes is an intermediate species between Chry- 

 soecia and Polenta and may best be tentatively placed in Chrysoecia 

 with which it agrees in tibial armature and possesses a not dissimilar 

 habitus. There is a slight difference in the frons, notably in the lack 

 of connection between the central tubercle and the raised ring, while 

 the horizontal plate below the tubercle is stronger. The authors do 

 not, at this time, consider this slight difference in the frons of any 

 special significance. 



The authors are placing Chrysoecia between Stiriodes and 

 Polentia.

Proboscis fully developed, rather long; palpi upturned, closely scaled, the 

 second joint reaching somewhat above the clypeal plate, the third joint short, 

 about one-half the length of the second joint, and reaching to the center of the 

 frons ; which has a large corneous prominence with raised edges and a central 

 horn which is more or less connected to the dorsal margin of the prominence 

 by rough chiten ; a corneous plate below it ; eyes large and round ; antennae of 

 male almost simple ; thorax clothed chiefly with scales, with some admixture 

 of spatulate scales, flattened hair and hair, the prothorax with a slight spread- 

 ing crest, the metathorax with a well developed spreading crest; patagia not 

 markedly curled upward at extremities; tibiae moderately fringed with hair, 

 unarmed ; tarsi armed only with thin or normal spines the fore tarsi rather 

 long; abdomen with dorsal crest at base only. Fore wing with the apex rather 

 acute but rounded, the termen evenly curved and slightly crenulate, the tonius 

 with slight scale-tooth ; veins 3, 5 from near angle of cell ; 6 from slightly 

 below upper angle; 7 connate with 8 + 9 from end of areole; 9 from 10 an- 

 astomosing with 8 to form the areole; 11 from cell. Hind wing with veins 

 3, 4 from angle of cell ; 5 obsolescent from about one-third below middle of 

 discocellulars; 6, 7 connate from upper angle; 8 anastomosing with cell near 

 base only. 



The present genus apparently belongs between Nocloa and 

 Oslaria. It possesses a central process to the corneous prominence 

 somewhat as in Nocloa; altho this central process is not truncate; but 

 the fore tarsi are normal in length and are not armed with short 

 heavy spines or very short claws as in Nocloa (type plagiata). The 

 normal length of the fore tarsi are probably responsible for mirabilis 

 being placed by other authors in Basilodes where it cannot remain
