DESCRIPTIONS OF AUSTRALIAN ^SCHNINiE. 49 



depressed and converging, apical halves nearly horizontal, flattish^ hairy, 

 with well-rounded tips. Inferior appendage 1'8 mm., narrow-subtriangular, 

 much upcurved, as in type. 



Habitat. Mt. Kosciusko, N.S.W., at 5000-feet level. Taken by Dr. A. J. 

 Turner, Jan. 23rd, 1914. 



Type : Coll. Tillyard. 



This very striking and beautiful subspecies is very different from the type- 

 form in appearance, owing to the yellow colouring and greater size of its 

 markings. It is of interest in showing the transition of a species possessing 

 the coloration of Group II. (see above) back to that of Group I. on taking- 

 possession of an alpine habitat, where tall trees and dense forest are not 

 present. The effect of living more in the open is seen at once by the develop- 

 ment of the brighter coloration, while it is curious also to note the tendency 

 shown towards a shortening of the superior appendages towards the form 

 seen in A. unicornis and other species. 



This is the first record of A. parvistigma from the Australian Alps.
