Perigea albigera Gn. 



1852, Gn., Spec. Gen. V, Noct. I, 228, Perigea. 



1908, Hamp., Cat. Lep. Phal. B. M., VII, 328, pi. CXVI. f. 14, PerigeaK 



Two male specimens from Brownsville, Texas, and one male 

 specimen from Chokoloskee, Florida, were sent to Mr. Schaus for de- 

 termination, the palpi being peculiarly modified as in some other 

 tropical species assigned to Perigea by Hampson. 



The present species would fall between sections II and III of 

 Perigea according to Hampson's tables (1908, Cat. Lep. Phal. B. M., 

 VTI ; the antenna being ciliated, possessing longer bristles, the shaft 

 not distorted; but the palpus has the basal joint large, the second joint 

 very long, unfringed in front but fringed in back practically its entire 

 length by long hair and hair-like scales, the third joint rather large 

 and similarly fringed. 



]Mr. Schaus' note reads : "Perigea albigera $ Guen.- was described 

 from 2 9$. I have a 9 (Aroe, Venez.) compared with type and 

 agreeing with description. If Hampson had the true $ I am sur- 

 prised he did not notice the palpi .... Our specimens are from 

 F. Guiana, Venezuela, Panama, Costa Rica, Guatemala, Cuba, Ja- 

 maica." 



The Barnes Collection also possesses a female from Black Jack 

 Springs, Texas (probably collected by Dr. Barnes). 



Perigea thyatiroides sp. nov. 



Male without peculiar secondarj^ sexual characters. Antennae heavily 

 ciliated. Head and palpi brown, mixed with some black. Collar black or black 

 and brown. Patagia variable, pale ochreous to dark olivaceous. Prothoracic 

 and metathoracic crests mainly black. Primaries : ground color variable, pale 

 ochreous, brownish, or dark olivaceous; basal line single, black obscured from 

 costa to submedian fold by a black patch connecting it to the t. a. line ; t. a. 

 line black, only distinct between the costal-basal black patch and a smaller 

 triangular black patch on the inner margin, distally outlined by white, mesially 

 outlined by violaceous-white between the black patches ; orbicular large, round, 

 concolorous, outlined by violaceous-white ; reniform large, semicircular, black, 

 with an inner crescent of ground color, the whole more or less outlined by 

 violaceous-white ; an oblique black blotch on costa, above cell, extending obliquely 



4Hampson figures a male from Paraguay. It is surprising if he had the true male he 

 did not notice the palpi which are quite conspicuous. He lists intermittens Wlk. and 

 berinda Druce (partim.) in the synonymy. It now seems best to await further work on this 

 group before listing these as synonyms.
