NEW RACES OF AUSTRALIAN BUTTERFLIES . 99 



All the trees on which barringtoncnsis was found were growing 

 on a slight ridge about a mile in length, and at an elevation of 

 4,356 feet. This differs generally from the type of locality in 

 both Victoria and New South Wales where the species appears 

 to favour trees growing right down in gullies. One exception is 

 in Gippsland, Victoria, where the food trees are on a hillside. 



Larvae were in all stages of growth, from very small ones less 

 than J inch in length to fully grown ones measuring § inch in 

 length, which indicated that the butterfly apparently has a fairly 

 long flying season. Quite a number of pupae was also found. It 

 was decided not to take any larvae other than those fully 

 grown and ready for pupation, because of the difficulties of feed- 

 ing them. The pupae were therefore placed carefully in a breed- 

 ing box which was kept dark, because it had been proved from 

 experiments with the Victorian race that if the pupa? are kept 

 in the light they will fail to emerge. 



On September 9, 1947, the first specimen, a female, emerged. 

 This was the first record of the female. This was followed by a 

 male, and then two more pairs in the same sequence. Coloured 

 drawings have been made of the larvae and pupae by Mr. P. J. 

 O'Brien of the National Museum. 



Addendum 



A stay of two weeks early this year (1948) resulting in a compre- 

 hensive survey of the northern, eastern and central portions of the 

 Tops has yielded further data worthy of note. Adults of barring- 

 tonensis were seen as late as January 20, at which time larva? 

 were in all stages and a few pupa' were collected. 



The distribution of this butterfly is quite extensive ; in addition 

 to Tubrabucea itself, life stages were collected at Tomalla, a 

 distance of 8 miles from Tubrabucea; near the headwaters of 

 the Tubrabucea river (1 mile distant) ; on the Upper Manning 

 near the Falls (5 miles distant) ; and at a spot 8 miles from Tubra- 

 bucea, on the track to Mt. Barrington. In each instance all speci- 

 mens were found between 4,000 and 4,600 feet elevation. At 

 Polblue, which is 9 miles from Tubrabucea, and at an elevation 

 of at least 5,000 feet, no larvae or pupae were seen, although a 

 thorough search was made of all food trees encountered. 



The male specimen described by Waterhouse in What But- 

 terfly is That* on page 194 as having been picked up on the 

 snow near Edward's Hut (elevation approx. 5,000 feet) was 

 probably carried there by rough weather from a lower altitude. 



Larvae were collected from Blackwood trees (Acacia mela- 

 noxylon) near the headwaters of the Tubrabucea river, and near
