MICROLEPIDOPTERA OF NEW GUINEA 
171 
In Me y rick’s key to the genera of the “Oecophoridae” in the Genera 
Insectorum the genera Delonoma and Tanyzancla (p. 11) are separated by 
the shape of the terminal segment of the labial palpus which is somewhat 
thickened in the former, slender in the latter genus. This is not correct, 
because the terminal segment of the palpus in Delonoma is slender as well, 
wdiich is stated by Meyrick himself in the original description of the genus. 
Therefore point 175 of the mentioned key should be corrected, e.g., as 
follows : 
175. Fore wing with vein 2 from 6 / e Delonoma 
Fore wing with vein 2 from near angle Tanyzancla 
Furthermore, paragraph 154 of the same key may give rise to confusion, 
as its second line, which leads to Delonoma states: “Hindwing with 5 not 
curved and approximated to 4 at base”. In fact vein 5 in the present 
genus is distinctly bent downward towards the base, and originates from 
about the lower third of the closing vein, between the veins 4 and 6 
Key to the species of Delonoma 
1. Fore wing with veins 3 and 4 stalked; costal streak with triangular transverse 
projections at 1 / 4 and s / 4 iothrinca Meyrick 
Fore wing with veins 3 and 4 separate; costal streak with a short inwardly 
oblique transverse streak at 1 / 3 . and a V-shaped mark at 3 / 4 pyrrhoplecta Meyrick
