grows. I have reared it many times from mines in Pipfturus 
leaves collected at various places in the S. E. Koolau Moun- 
tains: Palolo, Kaumuahona, Tantalus, and Pacific Heights, and 
also from Mount Kaala and Makaleha, in the Waianae Range. 
The large leaves of Pipturus often contain great numbers of 
the mines, even up to a hundred, but usually the larvae in most 
of them die or are parasitized so that but few of them reach 
their full growth and spin cocoons.. The cocoons are made on 
the under side of the leaf alongside a prominent vein, white and 
not very conspicuous. 
Any mention that I have previously made to micropetala in 
the Proceedings of the Hawaiian Entomological Society per- 
tains to this species. 
Philodoria pipturiana n. sp. 
Antennae pale fuscous, apical portion white. Palpi whitish, streaked 
with fuscous externally. Head sordid whitish. Thorax dark fuscous, white 
beneath. Fore-wings dark fuscous to nearly black, with several white mark- 
ings: a white costal bar outwardly oblique from about middle of costa 
extends about half-way across wing; another oblique white bar at two- 
thirds of costa, which recurves to the costa, terminating in a few white 
scales in the costal cilia; just beyond this is a curved transverse white bar 
nearly interrupted in the middle, its costal end terminating with a few white 
scales in the costal cilia (not present in the paratype); a longitudinal 
white streak on basal third of fold, followed by a large oval white spot 
about middle of fold; a large oval white spot on dorsum about at end of 
fold; cilia fuscous except for the white scales previously noted in costal 
cilia and a few white scales at base of apical cilia. Expanse of wings 
8-9 mm. Hind-wings and cilia dark fuscous. Abdomen fuscous. Legs pale 
fuscous, tarsi white spotted. 
Described from two specimens collected on Pipturus tree 
which had leaves containing leaf-miners, on the Upper Ham- 
akua Ditch Trail, Kohala Mountains, Hawaii, July 31, 1921. 
In color this species resembles nigrella from Kilauea and forest 
above Hilo, Hawaii, but the white markings are distinctly dif- 
ferent. The habits of nigrella are not known.
