PSYCHE. 



[February, 1902 



the genera may have to be merged in 

 with the Agliinae. 



4. Bunacinae. Antennae bipectinate, 

 tip filiform, or pectinated to the tip. 

 Vein IIIo is never detached so as to 

 form an independent vein. Wings 

 usually very large, and in the more 

 specialized genera closely approaching 

 the Saturnian Antheraea (a case of 

 parallelism or convergence), bi:t the 

 larvae are entirely different, not spinning 

 a dense cocoon and being armed with 

 stout long spines (in certain genera 

 spinulated), instead of soft tubercles 

 crowned with several small short spines. 

 Pupa like that of Eacles in type, ending 

 in a large spine-like cremaster, and 

 subterranean. Usta, Cirina, Imbrasia, 

 Thyella, Bunaea, Antherina, Nudaurelia, 

 Gynanisa, Lobobunaea, Salassa. 



5. Cyrtogoniinae. Antennae of $ with 

 a single pair of pectinations to a joint, 

 in venation differing from that of the 

 other groups, in veins IIi, IIo and II4 

 of the fore wings all originating at nearly 

 the same point, quite far beyond the 

 outer end of the discal cell. This is an 

 entirely provisional group (perhaps an 

 offshoot from the Bunaeinae) as my 

 material is imperfect, and we know noth- 

 ing of the transformations of the single 

 genus Cyrtogone. 



6. Eicdaemoniinae. An aberrant group 

 not improbably of full family rank, per- 

 haps belonging here, or near Urotinae. 

 The single genus is remarkable for the 

 excessively long tails of the hind wings, 

 the long slender palpi, the end of the 

 second joint extending just beyond the 



front, and the third joint very long; and 

 the venation. Head in front squarish ; 

 when denuded of scales fiat, scarcely 

 narrowing in front. Antennae of $ with 

 but a single pair of pectinations to each 

 joint. Maxillae very slender, not united, 

 but nearly half as long as the palpi. 

 Fore wings short and broad. Hind 

 wings small, triangular, the tail being 

 from three ( 9 ) to five times ( $ ) longer 

 than the main portion of the wing. Ven- 

 ation approaching that of Urota ; 10 

 veins in the fore wings, only 7 in the 

 hind ones. The venation of the wings of 

 the hinder pair is evidently affected by 

 the great development of the " tail," which 

 is strengthened by tlie three veins (IH^, 

 IVj, IV.2),no vein V (internal) detected. 

 The discal veins (" discocellulars ") very 

 unlike that of Urota or any other genus, 

 and together forming a very oblique, 

 bent or angulated line. The body is 

 slender ; the legs long and slender ; the 

 fore-tibial epiphysis rather long and 

 about two-thirds as long as the tibia it- 

 self ; the abdomen slender, that of the 

 9 clothed at the end with a large singu- 

 lar mop-like moss of dense, short battle- 

 door-like scales, with a lateral tuft on 

 each side. 



The (J genitalia show some remarka- 

 ble features which we have not met with 

 in this or allied families. While the 

 claspers are in the main like those of 

 Sphingicampa, etc., the suranal plate dif- 

 fers in shape and armature, being small 

 and short, with a basal pair of small 

 spines, and a second much longer pair 

 directed backward and arising from the
