C. bilineolata. 



Common. February to the end of May. Frequents the 

 flowers of ragweed. West Plains. 



C. antarctica. 



I took five specimens of this moth in the summer of 

 1895-96, but I have not since met with the insect. West 

 Plains. 



C. lichenodes. 



I have met with but two specimens of this pretty moth, 

 both taken in the month of January. West Plains. 



Elvia glaucata. 



This beautiful insect is fairly common during February and 

 March at the flowers of the ragweed. I have also taken it in 

 May and July, but have no record of its appearance in the 

 spring. West Plains. 



Hydriomena gobiata. 



Present nearly all the year round. The first specimens 

 appear in September, and may be taken right on till June. 

 Frequents the ragweed, and comes readily to " sugar." Hardly 

 two specimens of this moth are exactly alike ; in most ex- 

 amples the waved lines which cross the fore wings tend to 

 form an oblique central band, which in some cases is so pro- 

 nounced as to lose almost all trace of the lines which compose 

 it. There is also considerable range in the depth of the 

 ground-colour ; I have specimens ranging from pale brownish- 

 white to bright yellowish-brown. West Plains, Waihopai. 



H, deltoidata. 



Commonest in midsummer, but fairly numerous on rag- 

 weed in February and March. I found it in great profusion 

 on the limestone cliffs near Mount Linton, and have also taken 

 it at West Plains and Waihopai. This species varies even 

 more than the preceding, but I have not met with any form 

 strikingly distinct from the fine series of variations figured in 

 Hudson's " New Zealand Moths and Butterflies." 



H. rixata. 



Not common. Most plentiful in January. Eagweed at- 

 tracts a few specimens during February. West Plains. 



H. similata. 



Fairly common. November to end of May. During 

 February and May examples may be secured from the rag- 

 weed-blossoms. West Plains, Waihopai, Pahia. 



H. siria. 



I am indebted to Mr. Howes for my example of this 

 species. He found it fairly common at Waihopai during 

 November.
