segment. Antennae narrow, segmented, extend slightly beyond the second 

 legs in the female, slightly farther in the male to the point where the third 

 legs meet in the mid-line. Coxae- the first relatively large, the second 

 and third very narrow, the second smallest and greatly reduced by the 

 first legs. The amount of ventral abdominal surface showing between 

 the last coxae and the legs is small. Forewings terminate in both sexes a 

 short distance above or below, or on the same level with, the third legs. 

 Hindwings not seen on this surface in either sex. 



Dorsallv : Prothorax almost obliterated in the mid-dorsal hue. Spiracles 

 prominentlv elevated on all segments 1 to 8. Dorsal spines forming a 

 relativelv broad band, three or four deep, transversely across the upper 

 third of segments 3 to 7 inclusive in the female, and 3 to 8 inclusive in 

 the male. Each band is interrupted in the mid-dorsal line. The pair of 

 small upturned dorsal hooks is situated on segment 10 in the male, on 9 

 in the female. Movement takes place between all the abdominal segments 

 excepting the last three. Colour at first bright green, becoming somewhat 

 vellowish, and later dark giey to black. The only note I have regarding the 

 pupal duration is — " Pupated 25th May. 1919; emerged 14th July, 1919: 

 forty-nine days.'" 



Average Measurements cf Pupa. 



Dehiscence. 



The pupa emerges as far as the sixth or seventh abdominal segment. 

 The headpiece is separated laterally by the separation of the antennae, 

 and dorsallv by splitting along the epicranial suture. Vertical splitting 

 takes place along the central line of the mesothorax and prothorax, and 

 vertex dorsallv. The antennae remain attached by a small slip of the 

 vertex only. 



(12.) Nepticula fulva n. sp. (The Olearia Blotch Nepticulid). 



The Imago. 



Female. 8 mm. Head and prothorax light yellow ish-brown ; antennae 

 under 1 and over \ dark brown ; abdomen dark grey ; legs light-brownish. 

 Thorax and forewings pale-whitish densely irrorated with darker brown 

 scales ; a small irregular black spot in wing near dorsum at \, another in 

 centre a little beyond \, a third in centre of wing near termen ; the central 

 spot is the most constant. Cilia light brown, a brown cilial line found onlv 

 in very perfect specimens ; the whole wing and cilia with bronzy reflections, 

 seen only in some lights. Hindwings and cilia grey-brownish. In the male 

 the brown scales in the forewings are largely replaced by darker grev ones, 

 and the central spots, though still present, are not so prominent.
