"Lanra (full-grown). — Head pale greenish ochreous. Body light green 

 with dorsal ochreous line broken in the centre of each segment so that the 

 anterior portion tends to form a short inverted Y, and the posterior portion, 

 commencing as a fine line, thickens into a small elongate diamond-shaped patch, 

 again narrowing at the rear of each segment. A broken, subdorsal, ochreous 

 line is also present, situated dorsad to tubercle III and curved downward on 

 the posterior portion of each segment; traces of a spiracular line are present 

 on the thoracic segments. 



"The hair arising from the tubercles is long, dull-white and slightly barbed ; 

 the normal arrangement of setae on an abdominal segment is as follows :— 

 tubercles I and II are distinct but contiguous ; I has four long subequal setae, 

 II bears two similar ones and a further short posterior one, pointing backward. 

 Tubercle III shows one long central seta and two shorter anterior ones, bent 

 forward. On the first seven abdominal segments a single hair on the pos- 

 terior margin of the segment dorsad to the spiracle probably represents III a. 

 Tubercle IV -|- V is very large and situated directly on the lateral flange; 

 it bears about twelve hairs, mostly long. Directly behind them is a tubercle 

 bearing two medium-sized hairs and two short ones; this is presumably Illb 

 of Dyar. Tubercle VI, below the flange, bears ten to twelve hairs and VII 

 is represented by several hairs at the base of the prolegs. The thoracic seg- 

 ments show the usual modifications: on the mesothorax I -f II bears three 

 long, subequal hairs and one short anterior hair and on the metathorax this 

 number is increased by a single moderately long hair: both segments show a 

 single hair directly posterior to this group. Tubercle III shows four setae of 

 which the central one is the longest; in line with the abdominal spiracles near 

 the rear edge of the segment is a tubercle which bears one medium hair and 

 one small hair pointing backwards (? Illb). The prothoracic plate is not 

 well defined ; two large patches of white hair project over the head ; behind 

 these are two long single hairs and on the posterior portion three tubercles, 

 the central one bearing two hairs and each lateral one three. Two large lateral 

 tubercles with numerous hairs are present, the raised spiracle being situated 

 posterior to the upper one near the rear margin of the segment. Length 14 mm. 



"Pupa (Fig. 2). — Pale green, with long, white, subequal hairs; wing-cases 

 smooth with fringe of short hair only on margin of primaries. The ends of 

 the leg sheaths project free but unequally above the fifth and sixth abdominal 

 segments; the inner sheaths (prothoracic legs) reach to the rear edge of the 

 fifth segment, the outer ones (mesothoracic) to the middle of the sixth seg- 

 ment; beneath these a third pair (metathoracic) projects still further, reaching 

 nearly to the rear edge of the segment. The antennal sheaths are slightly 

 shorter than the prothoracic legs. Apex of pupa sloping gently forward to 

 base of antennae where a distinct crescentic flange or ridge is formed; a dis- 

 tinct sub-dorsal ridge is present, becoming obsolete caudad to the second abdom- 

 inal segment. There is a narrow, cream-coloured dorsal stripe, a broad sub- 

 dorsal one along the ridge, encircling tubercles I and II, two pale broken 

 lateral stripes, slightly downwardly oblique from front to rear, the lower one 

 broader and crossing tubercle III, and a creamy stripe along the lateral flange.
