length, and were pale yellow with brown heads. In a couple of 

 weeks' time, just after the second moult, they were 4 lines long, 

 pale green with a darker dorsal line of same colour, light yellow 

 side lines, and brown heads with two minute horns ; two pro- 

 tuberances had also appeared on the terminal segment. On 

 15th December, twenty-two days after leaving the eggs, these 

 larvse changed their skins for the third time, being now five lines 

 long and dull greenish brown in colour ; dorsal line indistinct, 

 dark green, and with a row of minute black dots ; side lines 

 yellow, very thin, and shaded above with brown ; head dull pink, 

 with two red horns. After the fourth moult, 23rd December, 

 they measured seven lines, and the green had completely dis- 

 appeared : general colour brownish ; dorsal line consisting of 

 grey suffused markings, one on each segment, those on first two 

 thoracic segments very dark ; sides of body dark brown, darker 

 beneath, and with distinct irregular dashes of same colour on each 

 segment between dorsal and lateral lines ; head brownish, hairy, 

 and with two horns ; terminal segment with two appendages. 



On 14th January the larvre were 12 lines long (i inch), and 

 fully grown ; general colour dirty brown, with irregular markings 

 of a darker colour ; head hairy, with two small red horns, minute 

 black eyes, and red mandibles ; terminal segment with two short 

 fleshy appendages. The larvae in general shape resembles that of 

 X. Kluyii, but differs in the body being thicker in the middle. 

 It is extremely sluggish in its habits, clinging closely to the food 

 plant and feigning death if knocked off. It assumes the chrysalis 

 state about the beginning of February. 



PujKti. — Chrysalis, 6 lines in length, dull brown with outlines of 

 head, wings, &c., darker and dusted over with dull red specks. 

 It is suspended by the tail and by a thread round the middle. 



Imago. — The perfect insects of the spring brood emerge in 

 October, the male on or about loth October, and the female a 

 week or so later. 



Mr. G. Lyell, jun., having advised me of the importance of 

 being sure of the correctness of dates of appearance of this 

 species, the following notes (taken from ray diaries for 1894 and 

 1895) may not, perhaps, be out of place : — 



1894. 

 Oct. 1 2. A', llobartia emerging ; took a perfect male. 

 ,, 13. Saw llobartia frequently. 

 „ 20. Caught a splendid specimen of female llobartia, and 



saw several specimens on the wing, 

 ,, 21. Caught six females and two males of llobartia fiying 



about young eucalypts (nearly all rubbed or torn). 

 ,, 25. Saw female of llobartia in good condition. 

 ,, 28. Good specimens of llobartia still to be met with.
