 view. 



Habitat: Hornsby, N.S.W. Only found in August. 



Types: Holotype male and Allotype female (Hornsby, Aug. 25th, 1917, 

 R.J.T.) in Tillyard Collection, Cawthron Institute. Nelson, N.Z. Also a set of 

 slides prepared from a third specimen (o") taken on same date. 



This fine species was discovered quite unexpectedly while searching for 

 Stonefiies during the coldest part of the year. The first specimen was found 

 resting on the inside of the black hollow trunk of a burnt eucalyptus tree near 

 a creek in a precipitous gully. Sweeping the bushes overhanging the creek 

 yielded two more specimens. The locality was visited and carefully searched 

 afterwards at all seasons of the year, without any further specimens being taken. 

 It is the only Caddis-fly known to me which is to be taken in August around 

 Sydney.
