8 New Species of Sterola, With Explanatory Notes.

forms in the collections | have examined, while the named mate- 
rial in the Bishop Museum examined by myself and in the U. S. 
National Museum examined by Mr. Timberlake has in many 
instances several distinct forms under one name, and is useless for 
identifying any of the previously-described species. The characters 
which I have employed to distinguish species are obvious charac- 
ters but their use necessitates a very careful examination of the 
specimens in hand and fine discrimination. While I have seen 
many distinct male forms, I have not cared to describe any that 
cannot be associated with their females, for the two sexes are 
often strikingly different and confusion would be the inevitable 
result. Ultimately, I believe, many more species will be reared 
from their hosts, the larve of Lepidoptera, and the relation of 
male and female forms established. The multiplicity of forms will 
astonish some, but this condition is paralleled in many other genera 
of Hawaiian insects; in fact, a meagre and scattered representa- 
tion of the families and genera of insects existing on the conti- 
nents and the presence of many numerically large genera are the 
outstanding features of the Hawaiian fauna. 
In 1900 the genus was found to be represented in Australia 
as well as in Hawaii. Ashmead’ described in that year two species 
from New South Wales to which Turner,® in 1915, added a third 
from Southwest Australia. Representatives of the genus have also 
been found by Muir in Fiji and Southern China and are described 
herewith. The range of the genus, which was once thought to be 
confined to the Australian Region, appears likely to prove very wide. 
The types of the species herein described are deposited in the 
Bernice Pauahi Bishop Museum at Honolulu.
