branches emitted at an unusual distance from the base of the wing ; 

 the apical portion is coloured in the same way as in the fore wings, 

 except that the luteous spats form a narrow, continuous, submarginal 

 fascia, enclosing a series of transverse, black spots more or less united 

 in pairs.

This species is allied to Saturnia Hesperus (Cramer, pi. 68. fig. a), 

 but is smaller, and has the dentated fascia of the fore wings extend- 

 ing in a straight line entirely across them ; it is also much more 

 brightly coloured. Both sexes have the fore wings emarginate along 

 the outer margin, those of the female being rather less so than those 

 of the male. The general colour of the wings is tawny brown ; the fore 

 wings with the fore margin thickly clothed with grey scales being 

 white towards the base ; the front of the thorax has a continuous 

 white band ; another extends also across the hind part of the thorax, 

 and is continued by a white bar along the wing for about one-third 

 of its length, where it is angulated, and extends nearly to the costa ; 

 it is inwardly edged with bright rosy, and outwardly in part with 

 black ; the vitreous patch which occupies the middle of the wing is 

 subtriangular, having a narrow white margin succeeded by a wider 

 black one. This spot is followed by a multidentate white striga, 

 edged with black on the inside and with rosy red on the out, running 

 nearly in a straight direction across the wing, and extending also in a 

 curved one across the hind wings to the anal margin. This striga is 

 followed in both wings by a rather wide space much powdered with 

 grey atoms, except towards the costa, which is more ashy coloured ; 

 the dull luteous margin is traversed by a slender, waved, black line, 

 followed by a white band, and towards the tip of the fore wings is a 

 black patch, outwardly dentate, succeeded by two smaller black ones 

 edged with tawny, and a short curved and dentated white line ex- 

 tends to the tip of the wing. 



The hind wings are very similar to the fore ones, having near the 

 base a slightly curved white streak outwardly edged with black, fol- 

 lowed by a nearly oval vitreous spot, edged with white and black, 

 slightly larger than the spot of the fore wings ; and the luteous mar- 

 gin of these wings bears a slender wavy black line, preceded by a row 

 of small rosy and black spots. 



The wings on the under side are coloured exactly as on the upper,
