the birdnest fern, Asplenium nidus. I have reared them from 
Palolo, Oahu, and Hakalau, Hawaii. They no doubt occur 
on all the islands where this fern does. In the Fauna Ha- 
waiiensis the species is recorded from Maui and Molokai. I 
have found larvae feeding among the sporangia of Elaphoglos- 
sum reticulatum in Palolo Valley, Oahu, which I failed to rear. 
It may be the same species, and yet it might be still another 
species of the same genus. 
Batrachedra syrraphella Walsingham. [Hyponomeutidae. ] 
The larvae of this species feed on the sporangia of Drvop- 
teris parasitica. They hide within a white silken tunnel pro- 
duced wherever they are feeding. I have reared it from 
Palolo Valley and from Waianae, Oahu; and have collected 
it besides at Niu, Wailupe, Kaumuahona, Hillebrand’s Glen, 
Waiahole and Kaala, Oahu. In the Fauna Hawaiiensis it is 
also recorded from Kona and Kilauea, Hawaii. 
Batrachedra sp. 
I found fronds of Pteris irregularis on Mt. Tantalus, Oahu, 
very much mined by a small larva which was taken to be of 
a species of Batrachedra, but no adults were reared to prove 
their identity. 
Batrachedra spp. 
There are four other native species of this genus whose 
habits are not known, but it is likely that they may be found to 
be attached to some of the ferns. 
At several places in the mountains of Oahu, Polypodium 
spectrum fronds have been found mined by a lepidopterous 
larva larger than the preceding. None have been reared, how- 
ever, so that the species of moth is yet unknown. 
Euhyposmocoma ekaha (Swezey). [Hyponomeutidae. ] 
The larvae of this moth feed singly on the underside of 
the fronds of Asplenium nidus. They eat off the parenchyma, 
leaving the upper epidermis which shows as dead patches. 
While feeding, the larva is protected by a covering of silk and 
frass, making a sort of covered way connected with a burrow 
in the midrib where the larva stays when not feeding. This 
covered way is shifted as the eaten-off area enlarges in size. 
This moth occurs wherever this species of fern is found in the
