All the specimens that I have examined show a surprising uniformity. 

 and no difference is noticeable between the male and female in size and 

 colour. Smaller and more compact than Hydriomena (,nhiata, it super- 

 ficially has a strong resemblance to Venusia verriculata. 



Taken at Mr. O'Connor's residence, at Titahi Bay, Porirua. Wellington,, 

 where it came in fair numbers to " treacle," light, and blossom ; November 

 to March.
