96 EEV. A. MILES MOSS OX THE 



The puparium consists of a moderately stout web on the surface of the soil, and is 

 2:enerally formed among leaves and rubbish. 



The pupa, like all Sesiinse with which I am acquainted, is exceedingly lively. 



Ova (fig. a). — Singly on the under or upper sides of the leaves of many diflferent 

 species of Euphorbiacese. 



Laeva. — First instar (fig. a). Light ochre with medio-dorsal stripe of brown 

 culminating in a short black tail. Head dark ochre. 



Second instar {tig. f). Plain green with a couple of lighter stripes enclosing the 

 dorsal area. Head dull green. Tail black, tipped with ochre. 



Third instar (fig. a). Lighter or darker green, with dorsal area more clearly 

 defined by light- and dark-edged lines. Caudal horn long, straight, sharp-pointed, 

 green in colour, and pink at the base. The segmental divisions are marked by 

 light skin-folds. A swelling of black and pink coloration is now observable on the 

 back of segment 4. 



Foiirth instar (fig. a). Light green, with an almost straight and rather slender 

 caudal horn. The two dorsal stripes are now light yellow, edged vt'ith narrow lines 

 of darker green above. Llead plain and round. Spiracles small and light. Legs, 

 claspers, and horn ochreous green. The dorsal swelling on segment 4 is now more 

 pronounced. 



Final instar (figs, b, c, d, e). Variable, green or grey-brown. The horn at this 

 stage is replaced by a -very short, rounded, nipple-like point, and the head is somewhat 

 flattened and delicately pencilled with black, the cheeks being lighter. The medio- 

 dorsal line of the leg-segments is continued down the centre of the face, and in the 

 brown variety is sometimes represented by a series of dark Prussian-blue spots along 

 the back of the abdominal segments. 



Fig. h. Dull black-green, dorsal stripes and spiracles pronounced in light and dark 

 colour ; head white-green and shining ; leg-segments yellow-green, highly adorned with 

 pink and white, and the skin-folds of segment 4 tending to conceal a broad transverse 

 disc of velvety black, surmounted by ochre and bisected with white Legs light pink, 

 ringed with black. Ventral area and claspers very dull green. 



Fig. e. At full growth well protected by resemblance to stem of tree-spurge. 

 Plain blue emerald-green. Stripes enclosing dorsal area from mouth to tail yellow- 

 green with fine black line above. Process on segment 4 less pronounced, the black 

 disc being faintly approached and followed by pink. Legs ringed with pink instead 

 of black, and the nipple-like point ochreous. The entire surface faintly freckled with 

 grey touches in linear arrangement. 



Fig. d. Blue-grey inclining to pink, and much freckled with tiny dark blue lines. 

 Anal portion purple-grey. The head and leg-segments correspond in marking to fig. h, 

 but ochre and warm brown in diff"erent proportions are substituted for the white and 

 green, and the crimson is only suggested by a warmer tone. All the colours are
