tlie middle; cell extending two-tliirds the wing, very broad at its end; radial from 

 upper angle of discocellular ; apparently a slender discoidal veinlet emitted witHin the 

 cell ; upper median from angle above end of the cell, third at a short distance below 

 the upper, second at one-seventh, and first or lower at nearly half before end of the 

 cell ; submedian slightly curved : hindwing very convex at the apex ; costal vein 

 bowed at the base, thence straight to apex ; subcostal curved and touching costal 

 near the base ; cell long, extending two-thirds the wing ; two subcostals from end 

 of the cell ; discocellular bent acutely in the middle ; apparently a slender veinlet 

 emitted within the cell ; four median veins, upper median from angle above end of 

 the cell, second at one-sixth, and first at nearly half before end of the cell ; submedian 

 and internal vein curved. Body short; palpi small, apex minute; antennae bipec- 

 tinated, the branches ciliated ; forelegs compactly pilose, hind tibise with four spurs. 



COBANILLA MARGINATA (Plate 124, Fig. 4). 



"Wings pale glossy ferruginous-yellow : f orewing darkest exteriorly, the costal and 

 exterior borders and cilia ferruginous-red ; a slight reddish lunule at end of the cell : 

 hindwing ferruginous-red along exterior border and cilia. Body whitish ; antenna

Family SATURNIIDiE. 



Winers very large and broad ; forewing falcate or rounded at the tip, generally 

 with an ocellus of varied size and form and more or less vitreous. In some genera 

 the hindwing is anally produced into a long tail. Antennae very broadly bipectinated 

 in male, with the branches in pairs, less so in the female ; proboscis short or obsolete ; 

 abdomen very large and stout in female. 



Larva either with rows of short tubercles surmounted with short divergent 

 hairs, the segments in some genera being also slightly hairy between the tubercles, 

 the tubercles sometimes on the anterior and anal segment mounted on a conical 

 prominence ; or with rows of short or long fleshy spines. In repose, the anterior 

 segments are contracted and held upward. 



Cocoon large, of a fine or coarse but firm silken texture, either oval, lengthened 



oval, or pyriform, attached to a twig by a silken peduncle, or to pendent leaves by 



silken threads. 



Genus ANTHER^A. 



Anthercea, Hiibner, Verz. bek. Scbmett. p. 152 (1818-25). 

 "Wings large, with a rounded vitreous ocellus at end of the cell. Male : fore- 

 wing triangular, costa much curved at the end, apex falcate, exterior margin very 

 oblique ; cell long, broadest before the end ; costal vein extending nearly to the 

 apex ; first subcostal trifid, emitted at one-fourth before end of the cell, second from
