no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 11 



is edged externally with pale steel blue; directly on the costa is a secondary linear black spot. 

 Below, at the beginning of the bay or sinus, is an irregular black spot, edged with very few 

 scattered blue scales. 



Hind wings with no discal spot. A median brown band curved a little outward on the 

 costa. A marginal curved whitish band beyond which is a deeper fawn-colored wide band, 

 edged heavily with black and tending to divide into rings, a little as in Rothschildia. This band 

 reappears beneath, but the other lines are nearly effaced. No discal spots on the under side, 

 though the apical eye like spot reappears. 



Expanse of the fore wings, 6" 180 mm. 



Length of a single fore wing, <? 88 mm. 



Breadth of a single fore wing, <? 38 mm. 



Length of a hind wing, 6" 60 mm. 



Breadth of a hind wing, 6* 37 mm. 



Larva. — Unfortunately the larva of either species of this genus is as yet unknown. 



Geographical distribution. — Central America, British Guiana, Dutch Guiana, and Brazil 



(Rothschild). Canta Gallo, among the mountains a little north of Rio de Janeiro (Mus. Comp. 



Zoology, L. Agassiz). 



RHESCYNTIS MORTH (Perty). 



Saturnia mortii Perty, Del. Anim. Art., p. 159, Tab. 32, fig. 1, 1834. 

 Rhescyntis mortii Kirby, Syn. Cat. Lep. Het., I, p. 745, 1892. 

 Rhescyntis mortii Rothschild, Nov. Zool., II, p. 35, 1895. 



Geographical distribution. — As observed by Rothschild this species has almost the same 

 range as R. hippodamia; it was originally described from southern Brazil, but the Tring 

 Museum possesses one from British Guiana. 



[Two other species belong to this genus — R. norax (Druce) and R. hermes (Rothschild). 

 An allied genus is Grammopella Rothschild, based on G. cervina Rothschild, from Peru (Nov. 

 Zool., 1908, pi. XI, fig. 5).] 



Rhescyntis norax is in general shape like [Philosamia] cynthia, but with no ocelli or corre- 

 sponding spots; basal and extradiscal bands ill defined; no apical ocellus. Two submarginal 

 lines on both wings. [Dr. Packard also adds, "it is an extreme departure from Attacus prob- 

 ably," but see the remarks above under the genus Rhescyntis.] 



GOODIA Holland. 



Goodia Holland, Entomological News, May, 1893, p. 177. 



Orthogonioptilum Karsch, Berlin ent. Zeitschrift, 1892, p. 501, taf. XX, fig. 1, May 15, 1893. 



Goodia Aurivillius, Ent. Tidskrift, p. 246, 1899. 



[Dr. Dyar writes that Goodia Holland was published at the beginning of May, 1893, while 

 Orthogonioptilum Karsch appeared in the part of Berl. Ent. Zeit. dated on cover "mitte mai 

 1893," and received at Library of Congress July 19, 1893. Goodia thus has clear priority.] 



Imago. — Head rather prominent; eyes rather large; front of the head only moderately 

 wide and narrowing perceptibly toward the labrum. Antennae of the male very short bipec- 

 tinated (about 19 or 20 joints in all), with 13 or 14 joints each bearing two pairs of pectina- 

 tions; those of the basal and distal pair spreading widely apart from the base and provided 

 with long dense cilia, which are curved at the end; the tip subfiliform, composed of 5-6 joints 

 of which all except the two last bear fine short minute vestigial pectinations, with long crowded 

 cilia. Palpi small and short, not reaching the front; brush like, the scales at the end scraggly 

 and irregular, with no sign of a third joint (probably only composed of a single joint) ; of the 

 shape and proportionate size of those of Pseudantheraea [Cremastochrysallis] arnobia. 



Thorax moderately stout; the collar distinct; vesture of moderate length. 



Fore wings about half as wide as long; unusually falcate, the costal edge much arched 

 and almost suddenly bent on the outer fourth; apex unusually sharp; outer edge deeply but 

 not suddenly excavated; inner angle squarish, and the inner edge shorter than the outer.
