CERTAIN BUTTERFLY GENERA — FIELD 115 



Venation: Figure 21. Forewing either with three radial veins 

 (R4+5 having anastomosed with R3) or with two radial veins (R3+4+S 

 having anastomosed with Mi); Ri long, nearly the same length as R2 

 or only slightly shorter. Hind wing with the distance between bases 

 of Cui and C112 greater than distance between Rg and Mi. 



Legs: Paronychium (fig. 29) slightly over one-half length of claw, 

 rather narrow, tapering and constricted near middle with its width at 

 base about one-half its length. 



Genitalia: Alale (figs. 5, 13) with lateroventral wall at base of 

 uncus not at all folded inward; subscaphium present, only slightly 

 sclerotized, harpe broadly produced apically and not acuminate and 

 with a small clasper flap above middle on inner face. 



Female (fig. 38) with eighth tergite not developed in dorsal region, 

 forming two sub triangular shaped lateral plates; these plates are much 

 broader than the lateral arms of the eighth tergite in Phulia {Phulia) 

 and are more distad of the eighth sternite than in that subgenus; 

 inner pair of genital plates greatly reduced, being a narrow sclerotized 

 smooth band and lacking the finger-like process; signum reduced in 

 size and with a very few dentations or entirely smooth and semi- 

 circular in shape; bm*sa lacking the accessory pouch found in most 

 pierids. 



Species: 

 1. Phulia {InfraphuHa) illimani Weymer, in Weymer and Maassen, in Stubel and 



Reise, Reissen in Sud-Amerika . . . Lepidopteren . . . pp. 98, 125, pi. 4, 

 fig. 12, 1890. 



Piercolias Staudinger 



Trifurcula Staudinger, Deutsche Ent. Zeitschr., "Iris," Dresden, vol. 7, pt. 1, 

 pp. 56-59, July 14, 1894. Type: Trifurcula huanaco Staudinger= PzercoZfos 

 huanaco (Staudinger), by reason of being single included species. 

 Preoccupied by Trifurcula Zeller, 1848 (Lepidoptera: Nepticulidae). 



Piercolias Staudinger, Deutsche Ent. Zeitschr., "Iris," Dresden, vol. 7, pt. 1, 

 p. 56, 1894; Grote, Canadian Ent., vol. 35, p. 139, 1903. This is a Stau- 

 dinger manuscript name, mentioned in the original description of Trifurcula 

 as a name that author formerly used for the genus. Grote applied it to the 

 genus after discovering that Trifurcula Staudinger was preoccupied. Some 

 authors have attributed the name Piercolias to Grote; however, following 

 section 115, paragraph 2, page 63 of the Copenhagen Decisions on Zoological 

 Nomenclature, 1953, the name Piercolias of Staudinger is here accepted, even 

 though it was originally a manuscript name. 



Andina Staudinger, Deutsche Ent. Zeitschr., "Iris," Dresden, vol. 7, p. ii (of 

 the Inhalts-Uebersicht), 1895. Rober, in Seitz, Gross-Schmetterlinge der 

 Erde . . . , vol. 5, p. 97, 1909. Type; Trifurcula huanaco Staudinger= 

 Piercolias huanaco (Staudinger), by reason of being sole included species in 

 Trifurcula, for which Andina is a substitute name. 



Type: Trifurcula huanaco Staudmger=Piercolias huanaco (Stau- 

 dinger).
