VII. TORTRICINA.— (SUPPLEMENTARY). 
Tuis paper is supplementary to that which I published on the Tortricina 
in the Transactions for 1882. It contains nine additional species, of which 
eight are new, the ninth having been previously known from the Hawaiian 
Islands ; and also some corrections of classification. 
I propose to recast the definitions of the Tortricide and Grapholithide 
thus :— 
Tortricidae: Lower median veins of hindwings almost always without 
basal pectination ; vein 2 of forewings rising before posterior third of lower 
margin of cell; genital uncus of male developed. 
Grapholithide : Lower median vein of hindwings pectinated with hairs 
towards base; vein 2 of forewings rising before posterior third of lower 
margin of cell ; genital uncus of male not developed. 
I am indebted to Professor Fernald, well known as a special authority on 
this group, for the information on which this change is founded. He 
states that the genital uncus never occurs in the Grapholithide, and con- 
siders that such genera as Ctenopseustis, hereafter described, should be 
therefore referred to the Tortricidæ; which amounts to saying that the 
possession of the uncus is a more valuable systematic character than the 
possession of the basal peetination. As Professor Fernald has devoted much 
labour to the investigation of material from all parts of the world, there is 
little doubt that he is correct, and I have adopted his suggestion. I have 
not yet found leisure to examine the genitalia of all the T'ortricina of this 
region, but I have investigated a few species, which appear to confirm his 
views; and in the case of the Pyralidina I have found the same character 
valuable for family separation. The genital uncus (when present) is a hard 
cylindrical, more or less downwards-hooked, process from the apex of the 
abdomen in the male, and in some groups of pU assumes complex 
forms. 
The oceurrence of the Hawaiian Chiloides straminea is interesting, and 
may be compared with the presence of the genus Heterocrossa in both 
regions. Probably they extend over the intervening space, but I have not 
at present any evidence of this. The other additional species are all of 
genera already recorded from New Zealand, and mostly interesting as repre- 
sentatives of the old indigenous fauna. Itseems probable that Proselena, 
Harmologa, and Heteroerossa will be found to be richer in species than I had 
previously anticipated. I think that Cacwcia alopecana is also peculiarly
