Paragyrtis inostentata, Walk. {Dichromodes griseata, Hdsn., 

 Trans. N.Z. Inst., vol. xxxv, p. 244.) 

 This correction is also necessary. 



Dichromodes simulans, n. sp. 



This species was discovered by Mr. J. H. Lewis on the Old 

 Man Range, Central Otago, at an elevation of about 4,000 ft. 



The expansion of the wings is about | in. The forewings 

 are dull bluish-grey, with two obscure slender yellowish-brown 

 bands ; there are three jagged blackish transverse lines, one 

 at £, one near the middle, and one at £ ; there is a series of 

 black and bluish-grey marks on the termen. The hindwings 

 are yellowish-brown, clouded with dull-brown towards the base 

 and termen, leaving the central portion paler. The cilia of al! 

 the wings is yellowish-brown mixed with black. 



This species has a deceptive resemblance to Notoreas jidva, 

 from which it differs in the following respects : The wings are 

 somewhat broader, the transverse lines more indented, the cilia 

 not strongly barred, and the antennae of the male unipectinated. 



The perfect insect appears in February. 



Porina senex, n. sp. Plate XV, fig. 4. 



This interesting species was discovered by Mr. J. H. Lewis 

 on the Old Man Range, Central Otago, at an elevation of about 

 4,000 ft. 



The expansion of the wings of the male is about If in. All 

 the wings are very sparsely covered with hair-like scales. The 

 forewings are very pale ochreous, irregularly mottled with 

 blackish-grey. There are two rather large irregular patches of 

 the pale ground-colour on the dorsum near the base, and two 

 obscure oblique bands parallel with the termen. The hind- 

 wings are brownish-grey, with the veins and termen strongly 

 marked in dark-brown. The body is ochreous-brown, with 

 several tufts of very pale ochreous hair near the middle. The 

 antennae are strongly bipectinated. 



A single male specimen of this insect was bred in February 

 from a pupa found under stones as above. 



The only other New Zealand Porina with pectinated antennae 

 is P. dinodes. The present insect may be immediately dis- 

 tinguished from that insect by its very much smaller size.
