Under side of the wings red center and a broad almost oval white central spot. On the 

 hind wings the ocellus is reduced just as in P. rubrescens. 



The ? is very different, there is no ochreous or pink hue, but the ground color is olive 

 green, paler along the edge beyond the extradiscal line of both wings, but the lines and ocelli 

 are the same. Ocellus of the fore wings large, round, black, only the center white, with a few 

 pink scales. The' abdomen is banded above and with scattered long light hairs; and beneath 

 olive ochreous, with a lateral row of dark irregular roundish spots. 



Expanse of fore wings, s 70 mm. ; 9 95 mm. 



Length of fore wing, <? 39 mm. ; 9 52 mm. 



Breadth of fore wing, S 21mm.; 9 30 mm. 



Length of hind wing, <$ 30 mm. ; 9 42 mm. 



Breadth of hind wing, <$ 22 mm.; 9 31 mm. 



Ocellus of fore wing, e? 1\ by 7^ mm. ; 9 9 by S \ mm. 



Ocellus of hind wing, s %\ by SJ mm.; 9 10 by 10 mm. 

 Geographical distribution. — Chile (Franck). 



Subfamily 3. Urotix^e Packard. 



Head of moderate size; front moderately wide, and not narrowing toward the oral region; 

 its vestiture either not very long and shaggy (Urota), or quite shaggy in Eudelia and the hairs 

 spreading so as to partially conceal the eyes. Antennas of the male plumose, but a single pair 

 of pectinations to a joint, in 9 but little less pectinated than in & . Palpi short, porrect or 

 depressed, feeble. Maxillae not visible. 



Fore wings falcate, the apex squarish, not acute or much produced; outer edge with a 

 shallow (Urota) or deep excavation (Eudelia), inner angle well rounded. Hind wings in <? 

 with a well marked tail about one-fifth to one-fourth as long as the wing itself; in 9 there is 

 instead a distinct angle; apex of the whig well rounded. The abdomen in <? does not extend 

 to the inner angle of the wing. 



Venation: There are 11 veins in the fore wings; discal cell rather small, the outer side 

 formed by the discal veins taken together, is short and straight not oblique; vein III 2 either 

 partly detached (Urota) or wholly so (Eudelia), forming a true independent vein. In Urota 

 the venation of the fore wings is much as in Aglia tau, though that of the hind wings is quite 

 different; in these the two discal cells taken together are oblique (Urota) or extremely so 

 (Eudelia), vein III 3 alone entering and supporting the s tail. There are eight veins in the 

 hind wings. 



Legs moderately long; the <? fore tibial epiphysis in Eudelia very large, nearly as long 

 as the tibia itself. 



The two genera forming the types of this group (and Cercophana most probably) can not 

 apparently be placed in the Agliinse, though very near Aglia. Cercophana is tailed, and seems 

 to be near Eudelia, and the larva is apparently similar to that of Aglia; on the other hand 

 they can not be placed in the Bunseinse; at present it seems best to provisionally assign the 

 three genera to an independent group, until the larva of Eudelia has been discovered. 



Also the larval characters, the two separate dorso-median tubercles of Urota, forbid the 

 assignment of that genus to the Agliinse or Bunseinse ; on the other hand there is a resemblance 

 between the full fed larva of Aglia and Cercophana. 



Larva. — Body cylindrical, generalized in its outlines, head large, round, unarmed; tubercles 

 very minute, reduced, flattened, giving rise to flattened seta?. On the eighth abdominal seg- 

 ment not a double (fused) median tubercle, as in Bunandse and most Agliinse, but two separate 

 minute ones. The discovery of the first larval stage of these genera will throw much light on 

 the phylogeny of the group; at present it appears as though it may have sprung from some 

 primitive spined form, resembhng the freshly hatched larva of Arsenura and Aglia. 



[A separate memorandum notes :] Larva with multisetose tubercles. [The same (provisional) 

 memorandum refers Tagoropsis, Urota, Usta, and Ludia to Urotinse, but notes that Ludia and
