S. ustimacula. 



Fairly common in low-lying bush. 



S. trivirgata. 



Abundant in dry open country. The markings appear to 

 be constant, but there is unusual variation in point of size. 



S. chimeria. 



A few examples in bush during February. 



S. colpota. 



Abundant in swampy bush in January and February. 



S. asterisca. 



Rare. One or two at light in February. 



S. exilis. 



Common, and generally distributed. 



S. encapna. 



Durmg February I found this species in fair numbers in a 

 swampy situation here. It is not easy to follow its move- 

 ments when on the wing, as its flight is erratic and rapid. 



Platyptilia haasti. 



P. falcatalis. 



The moth referred to a.s falcatalis in the "Catalogue" 

 (Trans. N.Z. Inst., xxxiii., 167) should be haasti. I have, 

 however, since found the true falcatalis at Wailiopai. It ap- 

 pears to be much scarcer than haasti. 



Pterophorus lycosemus. 



Several examples in December. 



P. monospilalis. 



A few, associated with lycosemus. Are they varieties of one 

 species? 



Pyrgotis pyramidalis. 



Otatara in October. Not so common a,s plagiatana. 



Harmologa sisyrana. 



H. oblongana. 



I am indebted to Mr. Lewis for examples of these insects. 

 They were taken at Wedderburn. 



H. amplexana. 



Fairly common.
