origin of third median branch ; two parallel lunulated lines running 
transversely across the wing from third fourth of median nervure to inner 
margin, the outer line darker than the inner: asmall black rounded 
interno-median spot near the base; three transverse irregularly un-

The larva of this species is extremely beautiful ; it is bright sap- 
green with the underparts bluish green, the spiracles even paler, 
almost white, the prolegs reddish ; a narrow white stripe gradually 
widening from behind the head to the front of third segment, and 
thence to the tail ; a series of eight elliptical crimson-edged white spots 
crossing the segments, and continued obliquely downwards between 
the spiracles in the form of ill-defined oblique yellowish stripes, the 
last spot also continued upwards by a whitish stripe running to the 
base of the anal horn, which is yellowish green; an indistinct 
oblique yellowish stripe from outer angle of anal claspers. Length 3 
inches 13 line; length of anal horn 34 lines. 
Both larva and pupa are of nearly the Smerinthine type, proving
