COPAXA (Walker). 1 



[Copaxa Walker, Cat Lep. Het. Brit. Mus., V (1855), p. 1235.] 

 [Type according to Kirby, C. decrescens Walker.] 



Notes on Copaxa trotschi Druce (Biol. Centr.-Amer.); fore wing very falcate; three lines, 

 basal widely dislocated; extradiscal straight, broad, dark, bent outward toward apex; & median 

 line, scalloped and ending on the ocellus, no such line in hind wing, but latter has a basal and 

 two distinct extradiscal lines. Ocelli more or less pear-shaped, being produced backwards, 

 i. e., toward the median vein, each with a pear-shaped clear space. 



Is this a primitive or specialized genus ? 



[Venation: Various species have III 2 _ 3 joined to end. C. disjuncta has III 2 and III 3 



separate.]

COPAXA CANELXA Walker. 



Brazil; three <? , one 9 in Paris Museum. Fawn color; ocelli alike on each wing; three 

 bands on both wings; female antennae well pectinated. One male from Mexico is deep orange 

 red, with the ocelli on fore wing larger than on hind wing. 



[COPAXA (?) LAVANDERA (Westwood).] 

 Plate CV, figs. e-f. 



[At the Paris Museum Dr. Packard examined an example from Mexico (the species name 

 credited to Boisduval) and noted "Very near Saturnia."] 



[SATURNIODES Jordan, 1911. 



Based on S. medea (Saturnia medea Maass.) from Ecuador, of which Jordan describes three 

 subspecies from Peru, carina, charila, and miles; the last from an altitude of 12,000 feet. Dr. 

 Dyar adds to the genus 8. oclcendeni (Druce, Ann. Mag. Nat. Hist., (7) XVII, p. 411, 1906). 

 In the United States National Museum is a male of this genus from the mountains of Peru; 

 Dr. Dyar notes that it looks a good deal like Agapema.]. 



[OPODIPHTHERA Wallengren, 1859. 2 

 Plate CXII, figs, a, b. 



A genus of the Australian region. 0. astrophela (Walker, 1855) and 0. fervida Jordan, 

 1910, are from Australia. 0. papuana Rothschild, 1904, 0. albicera (Roth, and Jord., 1907), 



1 [Copaxa maTona Schaus, of which I examined the typo in the U.S. National Museum, has fasciculate antennae, and can not belong to Copaxa. 

 It is a most singular species; a sort of purplish red, with dark lines crossing the wings, part of them on the veins, part modified transverse bands, 

 but all narrow and similar. No discal ocelli or spots. A chalky-white subapical mark on primaries.) 



2 l Wallengren's original description of Opodiphlhera (6fv. Kgl. Akad. for 1S5S, published 1S59), kindly supplied by Mr. Watson, is as follows: 

 " Antennas utriusquo sexus pennatas, maris latiores; pecten utrinque duplicatum, radiis tequalibus. Palpi brevissimi, hirsuti, articulis indi- 

 stinctis. Caput retractum, in thorace intrusum. Frons hirsuta, per medium perpendiculariter haud canaliculata. Thorax antice declivus, supra 

 depressus, dense vQlosus scapulis brevissimis. Abdomen villosum, crassum. Pedes usque as apicem tarsorum dense hirsuti, prassertim apud 

 marem. Villositas tibiarum et femorum longissima. Alarum forma fere ut in genere praecedente, sed apex anticarum nunquam falcatus, et alse- 

 magis tenues, pragsertim in feminafere subdiaphanos. Angulus anticusal. posticarum fere rotundatus. Costae alarum omninout in Saturnia, sed 

 cellula! in partes 3 per plicam furcatam divisae. Fam. Satumides. Species typica: O. varicolor n. sp., e Nova Hollandia." O. varicolor is a syno- 

 nym of O. astrophela.]
