 lobe. Length of the body, 4 mm. ; expanse of the wings,

Genus Helicopsyche, Hagen (1866). 



Spurs 2.2.4, long, but the exterior spur on the anterior 

 tibia is minute, and that on the other pairs is slightly shorter 

 than the internal ; the subapical pair on the posterior tibi» 

 near the apical. 



This genus was founded originally to include the remark- 

 able heliciform larvae-cases made of grains of sand, which 

 have only lately been hatched out in North America and 

 Europe. In New Zealand these cases are very numerous in 

 running streams, but the larvae have not yet been -reared. 

 Three forms — probably indicating three different species — 

 exist, but it is doubtful if they belong to Relicopsyche, as no 

 adult insect of that genus has as yet been described from 

 New Zealand. It is more probable that they belong to 

 Pycnocentria.
