no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 89 



Dirphia. [Dr. Packard would doubtless have wished to revise and extend these preliminary 

 notes. In Kirby's Catalogue both T. socialis and Dirphia hoegei Druce (from Mexico) appear 

 in Ormiscodes. Dirphia angulifera Walker and Thauma ribis Hy. Edwards (which in Kirby's 

 Catalogue appears in a different family) are synonyms of T. socialis. T. ribis (Proc. Calif. 

 Acad., V (1S75), p. 266) was said to be from Vancouver Island, where it must have been intro- 

 duced. The species inhabits Peru and Chile.] 



PHRICODIA Hiibner. 



[Phricodia Hubner, Verz. bek. Schmett., p. 187.] 



[Kirby lists 25 species, all Neotropical except P. (?) albida Plotz, from west Africa.] 



Imago. — 9 . Head, front as in Dirphia. Palpi small, rather slender, not reaching the 

 front, otherwise as in Dirphia; the tlrird joint well developed but drooping. [Antennae wanting 

 in specimen examined.] 



Thorax somewhat shaggy, but with no specialized flattened scales, the vestiture being long, 

 but soft and woolly. 



Wings very broad, much as in Dirphia, the 9 abdominal tip extending slightly farther than 

 in Dirphia, as far as the inner angle of the hind wings. Fore wings of the same shape as in 

 Dirphia, the costa only slightly arched ; apex rectangular, and the outer edge slightly convex. 

 Hind wings long and broad, much as in Dirphia. 



Markings: Instead of a discal spot only a faint diffuse discal line as in Dirphia; extra- 

 discal line oblique and not wavy, but as in Dirphia, irregular. Abdomen banded with snuff- 

 yellow and brown. 



Geographical distribution. — South and Central America; Jalapa, Mexico (Barrett). 



PHRICODIA AGIS (Cramer). 



Plate LIII, fig. 8. 



[Atlacus agis Cramer, Papillons Exotiques, I, pi. 30, F (1775).] 

 Phricodia agis Kirby, Syn. Cat. Lep. Het., I [p. 788]. 



Imago. — One 9 . Body and wings chestnut brown, head a little paler, snuff-yellow, 

 ochreous on each side. Palpi black brown. Fore wings chestnut brown, snuff-yellow on the 

 costal edge, and the veins also more or less snuff- yellow. A very faint diffuse smoky discal 

 linear discoloration which is obsolete beneath; no basal line. A straight, firm (not wavy or 

 scalloped) white extradiscal line, with the outer edge brown. No white costal spots or any 

 other white spots. 



Hind wings uniformly chestnut brown, the only mark being a faint pale extradiscal line. 

 No discal spot. Beneath, as on the upper side of the wings, but no traces on the fore wings of 

 the extradiscal line. 



Abdomen banded with snuff -yellow and black-brown; the end snuff -yellow. 

 Expanse of fore wings, 9 100 mm. 

 Length of fore wing, 9 48 mm. 

 Breadth of fore wing, 9 26 mm. 

 Length of hind wing, 9 37 mm. 

 Breadth of hind wing, 9 27 mm. 

 This species in its broad wings and general style of coloration and markings closely 

 resembles Dirphia hoegei. 



Geographical distribution. — [Mexico to Brazil, Kirby]; Jalapa, Mexico (O. T. Barrett). 



HYLESIA Hubner. 



[Hylesia Hubner, Verz. bek. Schmett. (1822), p. 186.] 



[The type of the genus, according to Kirby, is H. canitia Stoll from Surinam.] 



Imago. — <f and 9 . Head rather broad in front, subtriangular. Antennas of male short 

 with long joints, a single pair of long well-developed pectinations, those at the base very long
