ADDENDA AND CORRIGENDA TO PART I 
Isotenes epiperca Diakonoff, 1944 (Treubia, vol. hors serie, p. 42, 
pi. 14, fig. 4). We are satisfied that this species is conspecific with 
Isotenes melancalymma Diakonoff, 1952 (part I, pp. 97-99, figs. 94, 117, 
118, 119), syn. nov. 
Isotenes pudens Diakonoff, part I, p. 83 has better to be transferred 
to the end of the discussion of the species of that genus, as it is remote 
from other Papuan species recorded in part I, and belongs to the I. 
miserana group of species. 
Thrincophom ochracea Diakonoff, 1941 ( Treubia , vol. hors serie, p. 44, 
pi. 17, fig. 10) has been omitted from the key to the species of this genus 
in part I, p. 149. It can readily be discriminated from all other Papuan 
species by its tawny colouring. 
Indications of the sex of the following holotypes have to be added: 
Zacorisca bovisanguis Diakonoff, p. 51, holotype, male, 
Chionothremma obscura Diakonoff, p. 59, holotype, male, 
Chionothremma ochrieauda Diakonoff, p. 80, holotype, male, 
Chionothremma ocellata Diakonoff, p. 64, holotype, male, 
Chionothremma placida Diakonoff, p. 66, holotype, male. 
It may be specified, that the genitalia slide of Chionothremma mesoxantha. 
Diakonoff, p. 54, figs. 44 and 50, is of the holotype. 
The following corrections must be made: 
p. 26, line 7 from bottom, read “Comuti” instead of “Socii”. 
p. 29, lines 3 and 4 from top, read “the signa, . . .one signum, . . .two signa” 
instead of “the socii, ...one soeius, ...two socii”. 
p. 49, line 14 from bottom, read: “p. 36, pi. 14, figs. 1-2” instead of “p. 39”. 
p. 56, lines 12 and 11 from bottom, read: “p. 40, pi. 15, fig. 7” instead of “p. 36, 
pi. 14, figs. 1-2”. 
During and after the publication of part I of this paper descriptions of the 
following additional genera and species of Tortricinac from New Guinea have been 
published in the Proceedings oj the Koninklijke Nederlandse AJcademie van Weten-
