2. IODIS YEETUMAEIA, Gn. 



Expanse, 1' 6". 



This is the largest of the genus known to me. All wings 

 bright green, no centre spot. Collar green, costa and cilia light 

 yellow. A common insect. 



3. IODIS DICHLOEAEIA, On. 



Expanse, 1' 2". 



All the wings bright green, no centre spot. Collar bright 

 orange, costa and cilia straw-coloured. A very common moth. 



4. IODIS CAEEXAEIA, Gil. 



Expanse, 11". March, April. 



All the wings bright apple-green. There is a small and 

 rather indistinct purple spot on fore-wing rather below the 

 costa, and a large square red one in centre of hind-wing. Col- 

 lar, costa, and cilia reel. This is the smallest, and in this neigh- 

 bourhood the rarest of the genus. "When fresh it is a very 

 pretty insect. 



5. Hypocheoma occultaeia, Don. 



Expanse, male, 1' 7" ; female, 1' 10". March and April. 



A variable insect as to size. I have males only 1' 2" across 

 the wings. The upper side of all the wings is a bright silvery- 

 gray, with transverse wavy lines, and a black dash running 

 from the centre of the costa of fore-wing to middle. Under- 

 neath the wings are all snow white, with two egg-shaped black 

 spots near base, a larger one beneath centre of costa ; a crimson 

 line running from costa half-way across wing, beyond which is 

 a large black smear. The underneath of hind-wings show a 

 deep black border lined with crimson inside. There is also a 

 sharp-edged, triangular, cinnamon-coloured spot that appears to 

 be devoid of scales about the centre of fore-wing, the apex 

 pointing inwards. The antennae of male are plumose, but run- 

 ning to a point. Those of the female are simple. 



Larva. — Length, 2' 2 7 . Prolegs appear to exist only on the 

 twelfth and thirteenth segments, but the segments are very 

 crowded together, and the front pair may be on the eleventh. 

 The thirteenth segment is a bifid arrangement running to a 

 point behind, and cleft. No sign of any other prolegs, the 

 belly, even under a lens, appearing smooth and polished. The 

 legs proper are also very small, and nearly invisible when the 

 larva is at rest. The head terminates in a long pointed pro- 

 jection similar to that at the anal end, only it is hard, and not 

 cleft. Colour, all over alike ; dull apple-green, with a dull 

 crimson stripe down each side, in which are the spiracles, 

 which are small and black, and up the centre of the belly runs 

 a narrow yellowish-white stripe. Eeeds on white gum ; holds-
