Iiiuiqo. — 2 (J , 2 9 ■ Hody !iii(l wina-s pule fawn color or hrowni.sli ocherou.s. Abdomen of 

 the same hue a.s the head and thorax al>ove and lielow. Leg.'* darker, becoming- purplish on the 

 outside of the tibia? and tarsi. 



Fore wing's fawn color within and a little darker beyond the extradiscal line. Basal line 

 obscure, a little irregular, ol)lique, slightly curved outward behind the costal edge. Extradis- 

 cal line light brown, oblique, not sinuous in $ , very slightly siiuious in 9 . Apex of S very 

 acute, below the apex the edge is excavated, leaving a projection in the middle of the wing, while 

 between this and the inner angle of the wing is a rather deep hollow subdivided into two sinuses; 

 in 9 outer edge moderately convex, not scalloped. In $ the outer margin beyond the extra- 

 discal line is somewhat darker than the re.sfof the wing, and with scattered obscure dusk}- strigte, 

 while along the middle of the wing is a hoary purplisli or lilac discoloration, which in 9 is 

 wanting. 



Hind wings of the same hue as the anterior pair, liut reddish ])ink in tlie middle of the wing 

 extending from near the base of the wing to the extradi.scal line, but not reaching the costal or 

 inner edge, which is pale ocherous, and of the same hue as the outer edge of the wing beyond 

 the extradiscal line. A large black discal spot, a little larger and rounder in 9 than in S . The 

 extradical line is definite and a little curved in <? . in 9 much wider and more diffuse, and merging 

 into the pink area. Beneath, the fore wings are stained deep roseate in the middle, including the 

 large discal spot; extradiscal line pink behind, becoming wider, more diffuse, and tawnj' ocherous 

 toward and on the costa. 



Hind wings beneath with no piidv and no lines, the extradiscal being obsolete or quite faint. 

 and when visible broad and diffuse. In the $ the abdomen is slightly ringed with dark ocherous. 

 The genital armature is a.s represented on PI. lix, figs. 3, .3«; as there is no other species of the 

 genus known, the specific characters can not be drawn up with precision.

Geograplucal dhtrihution. — Jalapa, Mexico (O. T. Barrett); Mexico (H. Edwards). The 

 following localities are given by Druce: Costa Rica (Van Patten, GabI), Mus. Druce); Panama, 

 Volcan de Chiriciui (Arce in Mus. Druce); Colon (Boucard, Mus. Druce); Guiana, Surinam, Brazil. 

 Trinidad, "West Indies. He adds that the examples from Costa liica are the darkest and agree 

 fairly well with Cramer's figure. The specimens from Panama agree well with those descrilied 

 b}' Grote and Robinson, which Mr. Edwards apparently received from the eastern coast of Mexico. 

 It is recorded from South Amei'ica by Sepp and by Stoll; from the Brazilian coast at Rio b\- Bur- 

 meister. Peters states that it is tolerably common at Novo Friburgo. a town .30 miles north- 

 west of Rio de Janeiro, and he adds that its .southern range extends to La Plata. 



Jlahits. — Regarding the breeding habits of this interesting moth ^Ir. Otis W. Bairett writes, 

 luider date of May 12, 19()(), •■ Eggs of S;/ssphhi:ein(il!n(i are hatching to-day" (twelve days incu- 

 bation); "'oddest looking fellows imaginable." 



E(j(j. — It is very large compared with that of Anisota, being 2 mm. in length and 1.8-1.9 mm. 

 in width. It is closely similar in shape and nearly as large as those of luides imperial is and 

 C regalls, being flattened, oval, elliptical. The surface with obscurely hexagonal areas, and from 

 a central bo.ss arises a slender, fine hair, whicii projects into the interior of the egg, pre<'isely as 

 de.scribed under Eacles I nqjerialla.
