The mamake tree, Pipturus albidus, is endemic to the Hawaiian 
Islands. It occurs in the forests of all the large islands of the 
group, and is one of the trees which supports a considerable 
insect fauna, as shown by a paper on the subject in Proceed- 
ings Hawaiian Entomological Society, II, p. 153, 1912. At that 
time the leaf-miners attacking this tree were not so well known 
as now, but one species “being mentioned, and, as it turns out 
now, was incorrectly determined. 
Now that the leaf-miners of Pipturus have been more thor- 
oughly studied, it is found that there are several species, some 
of which closely resemble one another, but occur in different 
localities or on different islands, illustrating the production of 
species by geographic isolation. 
These leaf-miners all belong to the Lepidopterous family 
Tineidae. At present six species are recognized, and no doubt 
others will be found by further collecting in regions where no 
particular attention has been given to these insects. 
Philodoria micropetala Walsm. 
Fauna Hawaiiensis, I, p. 719, Pl. XXV, fig. 22, 1907. 
This species was described from a single specimen collected 
at Halemanu, Kauai. I collected specimens of it on Pipturus 
trees at Kokee (which is near Halemanu), on August 23, 1921. 
The trees had mined leaves, and I consider that the mines be- 
longed to this moth. It is found that the specimens agree .with 
the figure and Walsingham’s description of micropetala. That 
being the case, all of my previous references in Proceedings 
Hawaiian Entomological Society to this species occurring on 
Oahu as a leaf-miner in Pipturuws are in error, as the Oahu 
species is not the same as these Kauai specimens. I determined 
specimens from Pipturus on Oahu by comparison with the figure 
of micropetala, and as they nearly agreed, and as there were no 
other near related species known at the time, I felt that prob-
