172 AUSTRALIAN BLEPHAROCBRIDAE, 



Habitat: — Weeping Rock ami waterfalls below it, Wentwortb Falls, Blue 

 Mountains, N.S.W., 2800 feet. Larvae and pupae were found by myself in fair 

 numbers on Nov. 17th, 1921. The type scries of imagines was taken on Nov. 

 18th in the same locality, the females by myself as they drifted up against the 

 spray of the falls or alighted on the wet rocks, the males a little later on the 

 same day by M. Tonnoir, who accompanied me, and who observed them flying 

 high up in bright sunshine in the spray of the waterfall, just like tiny Mayflies. 

 Males were fairly abundant, but almost all out of reach of the net, being fifteen 

 to twenty feet up in the air. In lite, the eyes of the male glow in brilliant 

 green, like those of Neocurupira nicholsoni n.sp. 



This species differs from Apistomyia colUni Bezzi, found in North Queens- 

 land, (Bull. Soc. Entom. Ital, xliv.. [1912], 1913, pp. 67-69), in the wings being 

 purely hyaline instead id' "slightly infuscated, with the apical spot reduced to a 

 slight grey border," in the condition of r-m being fused above with R, the basal 

 piece of Rs being absent, and also in the abdominal pattern, the silver marking's 

 not being joined as transverse bands across the dorsum as they are in A. colli ni. 

 It appeal's to agree fairly closely with .1. collini in the form of the antennae. 



I dedicate this species to M. Tonnoir, the well known Belgian Dipterist, who 

 accompanied me to the Blue .Mountains on the occasion of its discovery, and 

 himself discovered the males of the specie-. 



In concluding this paper, I desire to express my thanks to Mr. W. C. 

 Davies, Curator of the Cawthron Institute, for the excellent photograph of these 

 delicate Hies from which Plate xliv. has been prepared.
