three-tenths of a millimeter, and the surface was irregularly corrugated. When 

 first deposited they were of a light cream color or almost hyaline with a glossy 

 surface, but after two days they turned to a deep flesh color." (Fernald, Pter. 

 N. A. 35, quoted from Fish, in litt.). 



Larva: "They were of the usual forui of larvae of this genus, though 

 perhaps a little more slender than some species; body cylindrical, stoutest in 

 the middle, tapering towards the extremeties: head small and polished, con- 

 siderably narrower than the second segment; segmental divisions well defined, 

 the skin rather glossy. 



"When about a quarter of an inch long, the ground colour is pale grey- 

 ish-olive, but this is almo.st hidden by dark purplish-brown dorsal and sub-dorsal 

 stripes, which give the larva a very dark appearance; head very pale straw- 

 colour, marked with smoky-brown, the ocelli black, and the mandibles reddish- 

 brown; frontal plate and anterior legs polished black. 



"In the next stage, that is, when about three-eighths of an inch long, it 

 has become considerably lighter in colour; the ground is glaucous-green, the 

 dorsal and sub-dorsal stripes purple, but more interrupted, and not so wide 

 as in the earlier stage; head of the same pale straw-colour, but not so clouded 

 with darker, though the ocelli are still black, and the mandibles reddish-brown; 

 the frontal plate is gradually becoming pale like the head, the black being con- 

 fined to the front in some specimens, in others to a black edging, more or less 

 broken all round. Ground of the ventral area and the prolegs uniformly 

 glaucous-green, the anterior legs now ringed with black only. 



"In the adult stage, about half to five-eights of an inch, the larva has 

 a still paler appearance. Ground-colour bright pea-green; head very pale 

 straw-colour, faintly tinged w^ith green, the large ocelli intensely black, and 

 consequently very conspicuous, the mandibles reddish-brown, frontal and small 

 anal plate of the same bright green as the ground-colour; the dark green 

 (slightly brownish anteriorly) pulsating dorsal vessel forms the dorsal stripe; 

 between it and the spiracular region are two greyish-white stripes, on which the 

 small black tubercular spots may be seen; below the spiracles is a still clearer 

 and more conspicuous white stripe; spiracles black. 



"Ventral surface uniformly of the same bright green of the dorsal area; 

 at the front and at the base of each anterior leg, is an intensely black spot; 

 and the prolegs are finely margined with black.'" (Porritt, Ent. Mo. Mag. 

 XXII, 103-4.) 



Pupa: "The pupa is a little over half an inch long * * * It has 'a longish 

 beak in front, projecting at a slight angle downwards from the head, pointed 

 at the tail; the wing-cases of moderate length, well developed, and the ends 

 of the leg cases projecting free from the abdomen." The colour is bright 

 pale green, dorsal line darker green, edged on the thorax with white; beak 

 white above, rust colour at the sides; there is also a conspicuous streak of this 

 rust colour on the hind part of the thorax, and the same colour also appears 

 (but more faintly) on the abdominal point, and at the tip of the leg-cases; 

 subdorsal line dark green, lateral line white.
