Among the Pieridw 1 may meiilioii Delias ni(jriiia, Ftib , whicli is 

 sometimes not uncommon, but usually flies round the taller trees, too 

 high to be readily caught ; the contrast between the white upper 

 surface and the richly coloured black, yellow, and st-arlet under-side, 

 give the butterfly a very striking aspect on the wing. Belenois Java, 

 Sparrm. (teutonia, Fab.) is here by far the most abundant species of 

 its family, and may be found plentifully throughout the summer on 

 some large bushes of the so-called " Native Orange " {Gapparis nohilis) 

 in the Botanical Gardens. In some years this butterfly multiplies to 

 an inordinate extent in the interior of New South Wales, and, like 

 other species of the group, collects in vast migratory flights. 8uch a 

 migration occurred on November 25th, 1903, and several succeeding 

 days, when absolute clouds of white butterflies, apparently all of this 

 species, were reported from various inland localities, travelling before 

 a hot north-west wind ; and thousands were to be seen crossing Port 

 Jackson, mostly from north to south. At the National Park on the 

 28th it was excessively abundant, and towards evening clusters of 

 twenty or thirty, consisting of both sexes in about equal numbers, 

 could be seen "camped" under the lee of almost every bush. The 

 butterflies had practically all disappeared by the 30th. 



The Heaperiid^e include a good many species, some of considerable 

 beauty and interest, and one or two (as Netrocoryne repanda, Feld.) 

 of fairly large size. 



As may be expected from so favourable a situation, the moths 

 are very numerous in species as well as individuals, but I can here 

 allude to only a very few, such as the conspicuous day-flying species 

 of Aqarista, one of which, A. glycine, Lewin, is very plentiful and 

 sometimes destructive in the larva state to the vines. The larval cases 

 of the PsychidcB are of great variety of construction, and are very 

 numerous and conspicuous in the " bush " as well as in the gardens, 

 where the large cases of the " bag-worm," Metura elongata, Saund., 

 sometimes four inches in length, are among the first objects of their 

 kind to attract the attention of the new comer. The large and hand- 

 some green larva of Anthenea eucalypti, Scott, which reminds one 

 forcibly of that of the South European Saturnia pyri, is often common 

 on the young gum-trees, and has also adopted as a food-plant the 

 South American Schinus molle, extensively planted as a shade tree 

 along the suburban roads. One of the most objectionable insects in 

 the " bush " is the larva of the Limacodid moth, Doratifera vulnerans, 

 Lewin, which is often found in very undesirable profusion on young
