[Dr. Packard has since described the larva of Rhodia, showing that it has a single median 

 dorsal tubercle on the eighth abdominal segment. Mr. J. H. Watson (litt. 1912) states that in 

 Cricula trifenestrata there are two penultimate tubercles, but in C. andrei there is only one.] 



[Mr. C. L. Pollard (litt. 1912) would restrict the Attacinse to Coscinocera, Attacus, RoihscliiMia, 

 Philosamia, Epiphora, Samia, CaUosamia, and Eupackardia. This includes the " Samia group " 

 and " Attacus group" of Packard.]

PERISOMENA CjECIGENA (Kup.). 



Plate XXX, figs. 8-9; XXXVIII, fig. 2; C, fig. 2. 



[Saturnia csecigena Kup., Neuentdecktes Nachtpflauenauge, 1825, p. 1. A species of southeastern Europe and western 

 Asia.] 



[Egg glossy, flat, and marbled with white and brown ; several deposited together. — Jordan.] 



Larva. — (Zeller's collection; two blown specimens.) Small, two inches long; body cylin- 

 drical, hairy; six rows of tubercles, all small, rounded, and not prominent; the dorsal ones of 

 second and third thoracic segments only a little larger than the abdominal ones, and all four of 

 the same size; one on side low down, but none on dorsum of prothoracic segment. On eighth 

 segment six tubercles, the two dorsal ones remote from each other, twice as large as those on 

 the side. Body and base of legs covered with dense fine pilifcrous tubercles. Color uniformly 

 pale horn brown, with no bright markings, lines, or spots. Head darker than body. [Jordan 

 says: Larva first bluish gray, then green, more rarely reddish, the hairs white, the small warts 

 yellow, below the stigmata a raised longitudinal line.] 



Cocoon. — Open, can see pupa through. [Color dark brown.] 



Pupa (two broken pupa skins). — Rather stout, end of abdomen truncated-flattered, and 

 with a stout hook on each side, curving inward. [Food plant, Querents.] 



Perisomena is near Opodiphtera astropJiela (Walker) (simplex (Walker)), from Australia. 



Polythysana from Chili (P. rubrescens) I have from Paris Museum is near this Perisomena. 

 [Polythysana was however provisionally left in the Agliinas by Dr. Packard. The opinion 

 here given is from a small slip of paper, under the above description of the larva of Perisomena.] 



CRICULA Walker. 



Plate LXXXIV, fig. 3; CI. 



Cricula Walker [Cat. Lep. Het. Brit. Mus., V (1855), p. 1186.] 



Euphranor Herrich-Schaeffer, Samml. Aussereur, Schmett., p. 61, no description: fig. 80; 1854. 



[Dr. Dyar writes that Euphranor included trifenestrata Hell, and multifenestrala H.-S. ; the title page of the work is 



dated 1S50-1858. Kirby gives 1858 for multifencstrata. E. multi/eneslrata is herewith designated as the type of 



Euphranor, which thus becomes a synonym of Copaea.]

Imago. — J , 9 . Head narrowing perceptibly in front, so that it is triangular and rather 

 narrow. Eyes large. Palpi well developed, depressed, the ends pointed, extending below the 

 edge of the front of the head. Maxillae not visible in specimens with the scales undisturbed. 

 Antennae of the male broadly pectinated to the tip, the joints long, the pectinations of both 

 pahs of the same length and with long cilia. Those of the female have but one pair of short 

 slender pectinations, the distal pair wanting, the vestiges of them appearing as slight teeth; 

 of the basal pair the inner ones are about one-fourth shorter than the outer ones, and all end in 

 three or four short setas. 



Fore wings falcate, especially in the male; the costa is much curved toward the apex; 

 the outer edge is excavated in the s , scarcely so in 9 ; the inner edge is nearly as long as
