however, yet seen the corresponding females. Several other 

 species from Invercargill show the same tendency to melanism, 

 which should be borne in mind when considering insects fi'om 

 that region. 



Cacoecia acrocausta, n. sp. 



3 . 19-21 mm. Head and thorax brownish-ochreous or

 than in S , ochreous-whitish, sprinkled with very pale fuscous ; 

 central fascia indicated by an undefined grey very zigzag shade ;

I took a male and female together at Christchurch in Septem- 

 ber, but had not ventured hitherto to describe them ; I have 

 now received four additional males from Mr. Philpott, taken at 

 Invercargill, where the species is common in October and Novem- 

 ber. It is allied to excessana, but quite distinct. 



Cacoecia orthropis, Meyr. 



Examples fi-om Invercargill sent by Mr. Philpott have the 

 forewings much greyer than Christchurch and Wellington speci- 

 mens, and the hindwings are also grey ; they appear to constitute 

 a geographical form only, and to afford an instance of the tendency 

 to a darker colouring mentioned above. 



Tortrix molyhditis, n. sp. 



(^. 12 mm. Head and palpi rather dark fuscous, palpi 2. 

 Aiitennal ciliation 1. Thorax dark glossy leaden-fuscous. 

 Abdomen dark fuscous. Forewings elongate, posteriorly dilated, 

 costa gently arched, apex obtuse, termen straight, rather oblique ; 

 rather dark glossy leaden-grey ; markings blackish-fuscous ; four 

 small spots on costa alternating with principal markings : a 

 stria marking outer edge of basal patch, strongly angulated in
