no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 239 



Mode of casting its skin. — Before molting the abdominal legs are folded together and the 

 crown or rings of both are contracted. 



One was seen in the act of ecdysis; the skin had split open at various places from one end 



of the body to the other. The thoracic legs become free or are drawn out of the old skin before 



the head is cast off. 



EPIPHORA WaUengren. 



[Epiphora Wallengren, Wien, Ent. Mon., IV (I860), p. 167. Type, E. mythimnia (Westw. )=scribonia Walleng.] 

 [Faidherbia Gtjerin, Compt. Rend., Ix (1865), p. 162. Type, E. bauhinise Guer.] 



[Kirby lists four species: 



(1) E. mythimnia (Westw.). South Africa. 



(2) E. perspicua (Butler). Old Calabar. 



(3) E. aibarina (Butler). Abyssinia. 



(4) E. bauhiniae (Guer.). West Africa. 



E. rectifascia Rothschild, 1907 (figured in Nov. Zool., 1908, PI. IX, fig. 3) is from Stanley 



Falls.] 



EPIPHORA BAUHINLE (Guer.). 



Plates XLIV, fig. 1; XCIV, figs, d, e.f. 



Larva. — Size and general shape of [Samia] cecropia larva, with blue tubercles ending in 

 vermihon; tubercles rather long and blunt at end, those on abdominal segments 4 to 8 all red. 

 A lateral row of blue spots, a pah* on each segment. Head pale, of same color as body ; body 

 is represented as whitish. From a poor colored figure in Museum at Paris. 



Cocoon. — Oval, with a stalk. A cocoon observed with two larvae in it. 



EPIPHORA MYTHIMNIA (Westwood). 



Plate XLIV, fig. 2; LXXXVIII, fig. h; XCIV, fig. g. 



PHTLOSAMIA Grote. 



Samia Hubner, Verz. bek. Schmett., p. 156, 1822? [Sherborn and Prout (Annals and Mag. Nat. Hist., 8th series, 

 vol. 9, p. 179) have adopted the date 1820 for this part of the Verzeichniss; but they admit that the precise date 

 is a matter of "pure speculation."] 



Philosamia Grote, Proc. Amer. Phil. Soc, XIV, p. 258, 1874. 



[Rothschild, Nov. Zool., II (1895), arranges the species thus:] 



1. P. cynthia (Drury). [Java.] 



2. P. lunula (Walker). [East Indies.] 



ab. obscura (Butler). 



ab. guerini (Moore). [Bengal.] 



3. P. walkeri (Felder)= cynthia auctt (nee Drury). [North China.] 



ab. iole (Westw.). [Assam.] 

 subsp. pryeri (Butler). [Japan.] 



[Rothschild has the type of P. walkeri. He also has two specimens of iole bred from eggs 

 laid by typical P. walkeri. Dr. Packard copied out the data from Rothschild, without indi- 

 cating his opinion of them.] 



Imago. — c? . Antennae pectinated to the end, those of the ? nearly as broad as in 3 . 

 Fore wings more elongated and falcate than usual, much more so than in Callosamia. Hind 

 wings much elongated posteriorly, triangular, more so than in Callosamia. 



The discal spots of the fore wings long and narrow, curved sometimes (vacuna), comma- 

 shaped and connecting the very distinct basal and extradiscal bands, and situated more or 

 less parallel with the costal edge of the wings; those of the hind wings are usually boomerang- 

 shaped, being much bent or sharply curved. The middle of the spots are clear, nearly 

 diaphanous, and the posterior side of the clear space is filled in with yellow ocher scales (cynthia). 

 These spots are much more specialized than in Callosamia. 



The subapieal ocellus is somewhat reduced, compared with those of Samia and Callosamia, 

 with a tendency to become flattened oval.
