of the Australian PyraUdina. 435 



Sydney, New South Wales; Melbourne, Victoria; 

 Lake Alexandrina, South Australia ; Hamilton to Lake 

 Wakatipu, New Zealand; from November to March, 

 rather common. 



Hydreuketis, n. g. 



Forehead vertical; ocelli present; tongue short. Antennae 

 three-fourths, in male shortly cihated (i), with projecting scales at 

 apex of joints. Maxillary palpi moderate, loosely scaled. Labial 

 palpi moderate, somewhat arched, somewhat ascending, 2nd jomt 

 roughly scaled, terminal joint moderate, cylindrical, obtuse, or 

 pointed. Abdomen in male with luicus moderately long, strong, 

 curved, with an upwards-curved shorter remote process from base 

 beneath; valves strong, exserted, scaled. Posterior tibiae with 

 outer spurs somewhat more than half inner. Fore wings with 

 veins 4 and 5 from a point or stalked, 8 and 9 stalked, 10 closely 

 approximated to 9 towards base, 11 moderate. Hind wings with 

 veins 4 and 5 stalked, 7 out of 6 near origin, 8 anastomosing with 

 7 from origin to two-thirds. 



This genus is almost exactly intermediate between 

 Paraponyx and Schmnohvus, and doubtless forms the 

 developmental connection between them. The larvae are, 

 I beheve, aquatic and case-bearing.
