Shell. — -Fairly strong ; shiny ; transparent ; very slightly roughened 

 within cells. 



Colour. — -When fresh laid, yellow. In four or five days darker orange- 

 coloured areas appear here and there on the shell, and later a black area 

 (the caput) appears at micropylar end. The larva can be plainly seen. 



Note. — Laid singly. Strongly attached to food plant — in fact, the eggs 

 can hardly be removed without breakage. A few days after being laid the 

 top of the egg collapses a great deal, and the whole egg assumes a very 

 dented appearance. Forty-three eggs obtained from one moth. Laid, 

 21st September ; hatched, 5th October = fourteen days. The larva emerges 

 at micropylar end.

 Trans. N.Z. Inst., 16, p. 71. See also Hudson's N.Z. Moths 

 and Butterflies, p. 57, pi. 7, figs. 22, 23 ; Fereday's List N.Z.

This little moth has been rare in Wanganui this year, but is generally 

 common, and greatly attracted by light. 



„ T _, Ovum. Plate II, fig. 9. 



Class.— Flat. & 



Shape. — Longitudinal section oval ; sides almost parallel. The micro- 

 pylar end is greater in height than its nadir. Top and bottom are flattened, 

 though at the micropylar end a cross-section is almost circular, and at the 

 base oval. Micropylar end flattened. 



Dimensions. — Length, 0-58 mm. ; height (at micropyle) 0-37 mm., (at 

 base) 0-26 mm. ; width, 0-37 mm. 



Sculpture. — Reticulations fine, forming a network of shallow hexagonal 

 and pentagonal cells over whole surface of egg. Diameter of cells, about 

 0-02 mm. 



Micropyle. — A small circular cell about 0-01 mm. diameter enclosed 

 in a rosette of elongated cells. The rosette is encircled by a band of cells 

 longer than broad, lengthened in a direction radial from the micropyle, 

 often four-sided, though sometimes five. These cells are about 0-02 mm. 

 long by 0-005 mm. wide. 



Shell. — Strong ; shiny ; transparent ; smooth within cells. 



Colour. — Very pale cream, turning to light yellow, and later to a brilliant 

 orange tint. 



Note. — Laid singly, and well attached to the object upon which they are 

 laid. The egg becomes somewhat dented after a week or two. Laid in 

 June and hatched in July.

Cidaria (?) cinerearia Dbld., DiefL N.Z., 2, p. 286. Larentia cinere- 

 aria Meyr., Trans. N.Z. Inst., 16, p. 83 ; 17, p. 64. See also

 cinerearia). 



This little moth is very common at Wanganui during the early summer.
