ing ants. . It would be an interesting observation to find out 
-at what time the larvae feed, and whether the ants guide them 
to and from their food, as I have observed with other species, 
This Ogyris has been found at Como attended by Camponotus 
intrepidus, and on the Richmond River I have noticed a third 
‘species of attendant ant. d/iletus zgnita is associated 
with Jridomyrmez nitidus, The eggs are laid at the 
base of wattle trees (A. pycnantha and <A.decurrens). 
‘The ants find the young larvae and attend them, 
whilst they hide near the base of the wattle in 
the day time. The larvae are usually partially covered in 
-by the ants, and may even be found in the ants’ tunnels or 
nests. I have not yet been able to determine where the 
larvae pupate. A tree at Killara that was known to have 
larvae at its base was carefully uprooted and examined, and 
all the ants’ tracks searched. Though eight pupae were 
noticed, thes2 were all parasitised, no empty pupal skins could 
-be detected, but there were many freshly-laid eggs. 
The larvae of the following Australian Lycaenidae are 
‘generally, if not always, attended by ants, though in many 
cases the ants have not yet been determined:—AMiletus deli» 
cia; M.ignita; Pseudodipsas brisbanensis; Lycaenesthes 
affinis; Theclinesthes miskini; Ogyris abrota; O. ianthis; O. 
oroctes; O. hewitsoni; O. amaryllis; O. genoveva; Arhopala 
amytis; A. eupolis; Jalmenus evagoras; I. eichhorni; I. 
actinus; I. daemeli; I. inous; Pseudalmenus myrsilus. 
Liphyra brassolis lives in the nests of the green ant, but 
feeds on their young, and is treated as an enemy. The larvae 
of the following species sometimes have ants running over 
them, but are not dependent on these for their existence :— 
Candalides heatht; Polyommatus boeticus; Catochrysops 
platissa; Zizera labradus. The following two larvae are well 
known, but have never been found attended by ants:—O. 
olane, M. hecalius. Ants have not so far been noticed at- 
tending any of the other known larvae. 
OBSERVATIONS ON ANTS. 
(By Mabel N. Brewster.) 
The following observations were made on ants kept in 
captivity:—The formicarium used consisted of a wooden 
board furnished with four legs, standing in a shallow vessel 
of water. At each corner of the board, which was covered 
with a layor of earth, was a piece of cork, one-third inch in 
thickness, and on these was supported a sheet of glass which 
served as a cover. The ants under observation were placed 
‘on the soil. ; :
