The two first slope inwards, the third one outwards. A rare 

 insect in this part. 



8. JE^OCHKOMIA VINARIA, Gil. 



Expanse, two inches. December and January. 



AVhen fresh, the thorax, body, and all the wings are of a 

 beautiful purple-red or plum colour, but this soon fades to a 

 yellowish-red. A broad yellow stripe runs from costal apex, 

 which is much hooked, across both wings in a diagonal direction 

 to centre of inner margin of hind wing. There is a black 

 centre-spot, with yellow eye, and an indistinct line near base. 

 The body is very thick and flat, and perhaps a beginner would 

 hardly take it to be a Geometer at all. 



Larva, length, 1' 10". Prolegs, 6, on 9-10-13 segs. 



On the top of back on the eleventh segment are two large 

 raised yellow spots with black circles. On the fourth segment- 

 are two hard black pointed horn-like projections with pale 

 yellow bases, and on the sixth segment are two more, but here 

 the horns are barely visible. The spiracles are small, but dis- 

 tinct, and orange coloured. The body is smooth, ground colour 

 brownish-green, darkest above. Belly nearly white. The back 

 is covered with minute white spots, from some of which a short 

 black hair issues, but it requires a lens to see these. Head 

 long and attenuated, reddish-brown in colour. Keposes with 

 the body thrown out perfectly straight from the twig. Is said 

 to feed on Hakea, but I have only found it as yet on Banksia 

 mar^inata. Not common here. 



9. Arhodia lasiocamparia ? On. 



Expanse, male, 2' 2 7 ; female, 3 inches, but varies a good deal 

 in size. November and December. 



Colour of all the wings bright yellowish-gray, minutely 

 speckled with darker. A small and sometimes not very distinct 

 centre spot on each wing. Sometimes, especially in the fe- 

 males, the whole of the wings are suffused with pink. This 

 moth may be easily known by a large dark purple blotch on 

 the underside of fore-wing near costal apex. The body is very 

 stout and thick. Antennre are shortly pectinated in the male, 

 simple in the female. Eather a scarce insect, and there is some 

 doubt as to the name. My insects do not appear to tally 

 exactly with Guenee description, and they may perhaps be 

 an allied species. 



Larva, about two inches long, colour greenish-red ; quite 

 smooth ; spiracles not very distinct. Prolegs on ten and 

 thirteen segments, the latter very broad and flat. A rudimen- 

 tary pair on ninth segment, but these are not used in walking. 

 Sits stretched straight out from the twig, but when touched it
