of hexagonal cells, twice as long as broad, lengthened in a direction radial 

 from the micropyle. The dimensions of these cells are — length, about 

 0-02 mm. ; width, 0-01 mm. Diameter of rosette is 0-05 mm. There is a 

 second band of fairly regular hexagonal cells ; diameter, 0-015 mm. These 

 reticulations are extremely fine and minute. 



Shell. — Strong ; transparent ; very rough ; has a slight sheen. 



Colour. — Dull heavy green, turning in a week to a light blue, and almost 

 entirelv covered with small circular purple spots about 0-015 mm. diameter. 

 A few days before hatching the egg is a light mottled-purple colour, and the 

 larva can be plainly seen. 



Note. — Laid singly. Well attached to object. Larvae emerge micro- 

 pylar end. Laid, 3rd January ; hatched, 14th January = eleven days.

Scarce in Wanganui district this year. 



Ovum. Plate II, fig. 7 ; Plate I, fig. 2. 



Class. — Flat. 



Shape. — Oval. Micropylar end flattened and slightly broader than its 

 nadir. Top and bottom much flattened. 



Dimensions.- — Length, 0-72 mm. ; width, 0-56 mm. ; height, 0-47 mm. 



Sculpture. — A network of hexagonal cells covers the egg ; very plain at 

 micropylar end, but becoming more and more indistinct as it approaches 

 the base. Cells about 0-04 mm. diameter. Very minute protuberances sur- 

 mount the reticulations at the points of juncture. 



Micropyle. — Situated within a rosette of about nine elongated cells ; 

 about 0-06 mm. total diameter. Very indistinct. 



Shell. — Strong ; transparent ; somewhat shiny ; roughened. 



Colour. — When fresh laid, white with faint greeny-yellow tinge. In two 

 days many of the cells on the egg turn a brilliant red. The number of 

 these red cells increases slightly, and in some caseb two or more unite. A 

 large irregular area of red covers the micropyle. The rest of the egg now 

 gets yellowish, and just before hatching all the red areas disappear, leaving 

 the egg banded with broad and indistinct russet-red markings. The larva 

 can now be distinguished. 



Note. — Laid singly, sometimes in small bunches or in rows, and inserted 

 in crannies. Well attached to object. Thirty-two eggs obtained. The 

 shell gets slightly dented. Laid, 14th October ; hatched, 2nd November 

 = nineteen days.

Mecyna blairdalis Dbld. 



Mecyna blairdalis Dbld., Diefl. N.Z., 2, p. 287. 

 A very common species at Wanganui, and is best taken by sweeping the 

 long grass in the fields during any part of the day.
