Megathynius aryxiia Dyar, Jour. N. Y. Ent. Soc, XIII, 141 (1905) (partim) ;

"Male. — Expands two inches. Upperside black and orange-fulvous ; costal 

 margin brown ; along the hind margin of both wings a broad black band, erose 

 within and opposite cell on primaries incised ; on costal margin, beyond cell, a 

 black patch which extends to median nervure, and there connects with a large 

 patch which occupies most of the disk ; between this and the border a broad 

 orange- fulvous band from margin to margin, but restricted opposite cell; on 

 costa a fulvous patch anterior to the black one; the basal area darker fulvous. 

 Secondaries have the disk black, much concealed by long, fulvous hairs, and 

 between this and the border a light band as on primaries ; fringes alternately 

 fuscous and sordid white, white prevailing on posterior half of secondaries. 

 Underside of primaries dark brown at base and on posterior half of wing quite 

 to hind margin, the apex densely sprinkled with gray-white scales ; orange re- 

 peated, but above median replaced by white ; the patch on costa repeated. Secon- 

 daries brown, wholly sprinkled with gray-white scales, most densely beyond 

 disk, and this area is somewhat clouded. A small white spot near base below 

 subcostal, otherwise immaculate. Body brown ; beneath thorax gray-white, shad- 

 ing toward abdomen into gray-brown ; legs reddish-brown, with many gray 

 scales and hairs; palpi white; antennae brown above, whitish below, tip dark 

 ferruginous. 



Female. — Expands 2.2 inches. Less black, more orange fulvous ; the borders 

 as in the male ; in one example the black patches are nearly as in the male, but 

 in the other they are greatly reduced. In this last one, on underside of primaries, 

 the orange band is broad and bifid, embracing the costal patch ; secondaries in 

 addition to the white spot near base, have a white patch, a cluster of white 

 scales, denser than elsewhere, near the inner angle. From one male and two 

 females taken in Southern Arizona. Another female was taken making four 

 examples. They are described as sitting in the sunlight on leaves of agave and 

 flying when disturbed to adjoining cliffs of rocks, alighting generally out of reach 

 of the net." 



There has either been a slight shifting of type labels on the 

 original specimens which served for description, or else Edwards con- 

 fused the sexes. The type specimens now in the Neumoegen collec- 

 tion are all females, although one has a 3 type label affixed ; our 

 figure PI. I, Fig. 4 is an exact counterpart of the types, according to 

 Mr. Doll, curator of Brooklyn Ins. IMuseum, who has kindly com- 

 pared the specimen for us; it also agrees with the second example 

 mentioned in Edward's description of the 9 ; the first example may 

 possibly have been a S , we have, however, been unable definitely 

 to trace this specimen as Mr. Doll writes us that the Neumoegen types 

 are identical. The type specimen in the Strecker collection, which we
