defined. The warm vinous character of the previous instar is now replaced by dark 

 sepia and many lighter touches above the green marks, on tlie anus and leg-segments, 

 and the head is lighter. 



Final instar (fig. d). Eemarkably snake-like, either end appearing as the head of a 

 snake. Sides ochreous, back rich sepia-brown in a strongly dentated broad band, 

 culminating on segment 12, with an oval patch of light maroon, which contains an 

 oval black ring, a l)lack spot, and a metallic plate or disc. This latter replaces the now 

 absent pink filament, and is similai'ly capable of rapid palpitation, catching the light 

 and flashing like a serpent's eye when molested. The dark ocelli in strong ochre are 

 retained on segment 5 and the pear-shaped marks in outline on segments 6 to 11, 

 but the green colour has entirely vanished. 



Pupa (PI. XV. fig. k). — Warm mahogany-brown, with stout rough cremaster and 

 prominent proboscis-sheatlj, porrected but not independent as in Protoparce.

Moderately common in the Interior, where the moth would occasionally be drawn to 

 light, or the larva traced, by its immense black frass of obscured hexagonal formation 

 lying on the path, to some creeper in the roadside bank or supported by bushes and 

 trees overhead. This plant, both by its appearance and also by the analogy of the 

 habits of X. tersa, is probably allied to Spermacoce (cf. fig../). 



Not being found on the coast, my opportunities for observing its life-history were 

 limited to the final instar of the larva and the pupa, which latter almost exactly repeated 

 the colour, markings, and form of X. tersa, next described. One out of two pupae in 

 May 1910 produced the perfect moth in little more than a fortnight of pupation. 

 The larva, though of a different subfamily from Pholus labruscw, is again remarkably 

 snake-like. The head and leg-segments retractile, segment 5 much puffed out and 

 adorned with a couple of grey light-ringed ocelli on longitudinal light lines ; these 

 terminate in the brown caudal horn, which is down-turned and extremely curved. 

 The dorsal area enclosed, especially in front, is orange-yellow marbled with rusty 

 red. Remainder purple-brown, with indication of seven oblique stripes directed 

 tailwards.
