The genus Ogyris. 279 



by Hewitson. There are however two other easily recog- 

 nizable forms obtaining in other localities in Australia, the 

 one from Coomooboolaroo, N. Queensland, and the other 

 from Brisbane ; these appear to be good constant local 

 races, so I have no hesitation in naming them. Mr. 

 Waterhouse tells me that he has taken this species feed- 

 ing on Lovanthvs linophyllus, Feu., at the Richmond 

 River, and on L. rclasiroides, Sieb., at Sydney. The egg is 

 plain, spherical, flattened at the top, and is usually laid on 

 the mistletoe stem near its origin with its host. The 

 young larva? are uniformly light brown (F. P. Dodd), and 

 subonisciform ; when full grown, however, they become less 

 woodlouse-like, as they then measure from 25 to 32 mm., 

 but when in motion they are considerably longer ; in colour 

 they are dirty cream colour to ochreous yellow above, and 

 purplish below, with black spiracles, this being the form 

 that is found in North Queensland ; those found in the 

 South however differ, and are, according to Waterhouse, 

 brownish-red above and yellowish below. They hide in 

 the cracks of the bark of the host tree or in holes in the 

 mistletoe during the day, or beneath the surface of the 

 earth, coming out at dusk and feeding at night, at which 

 time I am informed the ants associated with them are 

 likewise on the move ; the species of ants that Dodd has 

 found them with most commonly is sEcophylla vircseens, 

 but several other species also associate with them. They 

 evidently protect the larva?, and have been observed to 

 milk them ; in one instance an ant was observed to 

 approach a larva and wave its antennae over its terminal 

 segments, and then to lightly touch it with its fore-leg, 

 when a small globule of liquid was emitted from a small 

 retractible nipple-like organ on the dorsum which was at 

 once sucked up by the ant. The process was then repeated 

 on the other side, there being two of these organs, oue on 

 each side of the dorsum ; this happened two or three times, 

 and the larva seemed quite composed and in no way 

 incommoded by the incident. I possess larva? in spirit 

 both from Queensland and from Sydney, and the form 

 from Sydney is darker and more highly coloured than that 

 from the North. The pupa, some of which I have before 

 me, is very dark brown, almost blackish, of the usual 

 Lycsenid form ; it attaches itself by its terminal segments 

 to the under-side of stones or loose bark and spins a girdle 

 of silk across its back about the end of the wing cases and
