to both wings is broader and scalloped externally. The ocellus of the hind wing. is about the 

 same as in T. poly "ph emus ; the nearly clear space being as large and the yellow ring around it 

 as wide, but deeper orange. The two apical black spots and the rose patch underneath are just 

 as in normal T. polyphemus. It is of the same size, and the fore wings expand 11 cm. [Mexico.] 



METOSAMIA Druce. 



Metosamia Druce [Ann. Mag. Nat. Hist. (6), IX (1892), p. 276J. 



The only true generic difference from Telea is the markedly scalloped wings [of the males]. 

 It has no affinities with Samia, as the name would imply.

Metosamia godmani Druce [Ann. Mag. Nat. Hist. (6), IX (1892), p. 277]. 

 [This is the type of the genus.] 



Imago. — Also a large species, but the wings are not scalloped [in the female] and it apparently 

 scarcely differs from Telea polyphemus, from which it is evidently derived. In color and markings 

 it differs from M. montezuma and T. polyphemus in the basal line being formed of two white 

 spots, that near the costa being triangular, the other portion of the line being a straight slash 

 across the base of the submedian cell. Extradiscal band as in T. polyphemus, but on the hind 

 wings it is straight. Ocelli of the fore wings without the blue semicircle; that of the hind 

 wings with a small discal clear space, and no black or blue shade within, though there is a narrow 

 blue semicircle. Female antennas pectinated to tip. Length of anterior wing 83 mm.; ocelli 

 17 mm. 



Geographical distribution. — [Mexico.] 



METOSAMIA MONTEZUMA Salle. 



Plate LXXV, fig. 2; LXXVI, fig. 1. 

 [Saturnia Montezuma Salle, Bull. Soc. Ent. Fr., 1856, p. xcii.] 



Imago. — This species is in the antennas and shape of the wings just as in Telea polyphemus 

 except that the outer edge of the fore and hind wings are scalloped, especially the hinder ones. 

 The ocelli are almost identical; the basal line of the fore wings is disconnected. The extradiscal 

 black line is the same. The two apical black spots are as in Telea, but behind them is a white 

 patch lined behind with brown, this shade touching the end of the extradiscal band. In the 

 ocellus of the bind wing the clear space is smaller than in T. polyphemus. The outer edge is 

 divided into seven large scallops, that on the first median vein being a little longer than the 

 others. Expanse of fore wings 16 mm. 



Geographical distribution. — Mexico .

Mrs. Dimmock has contributed to Psyche (IV, 276) the following historical sketch of this 



insect: 



Harris (Kept. Ins. Injur. Veg., 1841, p. 279-280) describes the larva, imago, and cocoon of this species; later 

 (Treatise on Ins. Injur. Veg., 1862, p. 385, 387-389) he adds figures of the larva, pupa, cocoon, and male imago; and still 

 later (Entom. Corresp., 1869, p. 294-205) he again describes the larva. Morris (Synop. Lepid. N. A., 1862, p. 223-224)
