dull yellow band across the outer half of the fore wings. The Painted Day Moth, _Agarista agricola_, attracted the attention of our earliest entomologists by its brilliant colouration, and was described and figured in colours by Donovan in his “Insects of New Holland” 1805, and again by Dr. Leach in his “Zoological Miscellanies” published in 1815. It has a wide range from Sydney northward, and the several sub-species placed under this name extend its range to New Guinea and Timor. This is now the sole type of the Genus _Agarista_, in which so many of our species were formerly placed; it is a handsome black moth; measures up to 3 inches across the wings, the fore-pair of which are richly blotched with pale yellow, deep orange, and blue; in the hind pair the centre is bright red and blue, and the margin is white. The head and thorax are pale yellow above; the legs and under surface red; the tip of the abdomen dark orange. The larva is a handsome dark coloured caterpillar clothed with scattered and curious long clubbed hairs. [Illustration: Plate XXII.--LEPIDOPTERA. Family NOTODONTIDAE. 1. _Danima banksiae_ (Lewin).

The sound is said to be produced by the male rubbing his curiously clubbed antennae against a pellucid ridged area in the front of the fore wings. Hampson doubts this, and says it is probably caused by rubbing the tarsal spines against the ribbed space. _Hecatesia fenestrata_ is a pretty little moth, about 1 inch across the wings; is of a general dark brown tint; the outer margins of the fore wings are provided with a broad semi-lunate ribbed band (the musical apparatus) in front, and two white lines behind; the centre of the hind pair and abdomen richly blotched with reddish yellow; the head, antennae, centre of thorax, and outer margins of the wings marked with white. Three species of this Genus are recorded from Australia, two of which were described from the west coast, while _Hecatesia fenestrata_ has a range from South Australia into N.S. Wales. Family 4.
