t*. BuLLER, — Notes on some Species of Diurnal Moths. 23^ 



Common Tiger Moth. 



This species is not uncommon during the months of November and 

 December, and frequents hill sides and grassy slopes. Unlike the mountain 

 species, it keeps to the grass and stunted vegetation, chiefly " tauhinu.'" It is 

 not easy to distinguish when at rest, for the markings on the under-surface 

 of the wings very closely resemble dried grass blades and stalks. No doubt 

 this is for a protective purpose. It is very shy and wary, and to catch a 

 specimen means a long chase with the net. 



Hah. Welhngton. 



Common Grass Moth. 



Frequents grass, Escallonia, and flowering shrubs in general. It shows 

 a preference, however, for the common Scotch thistle when in flower. It is 

 very plentiful in all parts of the North Island, and may be found in any 

 grassy lane or meadow. It has a bold and swift flight, and a curious habit 

 of vibrating its wings very rapidly for a few seconds after setthng. It is 

 both diurnal and nocturnal in its habits. 



Appears in February, and lasts till April.
