MICROLE PIDOPTERA OF NEW GUINEA

very helpful for giving a survey of the known forms ; they should be added 
to descriptions as much as possible. 
Sketches of genitalia, wing neuration, and head were made by the 
author in pencil with the aid of a camera lucida and put in ink afterwards 
by the Indonesian artist of the Buitenzorg Museum, Raden Saleh. 
To avoid confusion it may be useful to stipulate in this place that in 
our descriptions of colouring and markings wc use the terms “inwardly 
oblique” and “outwardly oblique” always in the same sense, i.e. following 
the given fascia or marking in the wing of a set specimen in downward 
direction (i.e. from costa to dorsum), not upwards (i.e. from dorsum to 
costa, in which manner these terms would have an exactly opposite 
meaning). Furthermore it may be stipulated that the insects were studied 
for the making of descriptions with a magnification of 30 times. 
On account of our lacunary knowledge of the fauna of Microlepidoptera 
of New Guinea and of that of the neighbouring regions, it is evident that 
this paper had to be kept almost entirely systematic. We hope to venture 
a few general remarks on the character of the New Guinean fauna in due 
course. 
The following numbers will give an impression of the size of the col- 
lection: it comprises about 1400 specimens, belonging to 582 species and 
subspecies of 30 families; 1 family, 67 genera, 516 species, and 10 sub- 
species appear to be new to science. In the present part the families 
Alucitidae, Phaloniidae and a part of Tortrieidae are treated; 6 genera, 
94 species and one variety are described as new. 
The types are deposited in the Rijksmuseum van Natuurlijke Historic, 
Leiden. Para types and duplicates are to be deposited in The American 
Museum of Natural History, New York, and in the Museum Zoologicum, 
Bogor, Indonesia. 
The author wishes to express his sincere gratitude to many colleagues, 
who continuously and generously helped him with material and information 
throughout this work. It is this disinterested and generous help which 
inspired him to choose the memorable words of the American entomologist 
Brackenridge Clemens as a motto for this paper.
