The occurrence of this genus is very interesting. I have described 

 two species from New Zealand, and a third from Australia, and have 

 two other New Zealand species undescribed. It belongs to a very- 

 ancient group of the Concliylidce, now in course of extinction, and 

 represented in Europe only by the two species of Carposina, H.-S. 

 This genus is specially characterized in the group by the basal pecti- 

 nation of the lower median vein of the hind-wings, a structure other- 

 wise confined to the Grapliolithidce, and probably ancestral. The 

 species is closely allied to the New Zealand forms, but as there is in 

 general no affinity whatever between the New Zealand and Hawaiian 

 faunas, it is probably a case of a single persistent type once widely 

 dominant, but now lingering only in isolated situations.

Bepressaria indecora, Butl., Ann. and Mag. Nat. Hist., 1881,397, 

 and D. lactea, ibid., 398, are respectively ^ and ? of the same species. 

 This is not a Depressaria, and does not in fact belong to the Depressa- 

 ridcd, but to the Gelecliidce ; I cannot, at present, specify the genus, 

 but it is nearly allied to those hereafter following. I am unable 

 to understand why Mr. Butler has stated that this species possesses 

 the true neuration of Depressaria, since in fact it diffei"s widely in 

 that respect. The same may be said of D. gigas, ibid., 397, which is 

 apparently cogeneric with the preceding. No true Dejrressaria occurs 

 in Mr. Blackburn's collection, nor any allied genus ; and it may be 

 observed, that the genus is also wholly absent from Australia and New 

 Zealand. The so-called genus Chezala, Walk., alluded to by Mr. 

 Butler as a section of Depressaria, is virtually uncharacterized, and, 

 therefore, non-existent ; but the species on which it is founded (C. 

 allatella. Walk., itself merely a synonym of Cryptolechia privateUa, 

 Walk., and Crypt, latiorella. Walk.) belongs to the (Ecophoridce, and 

 is widely remote from Depressaria.
