A Pseudogonatopus is parasitic on small Delphacids and 

 apparently does not differ specifically from the somewhat 

 variable species found on the other islands. Echthrodelphax 

 fairchildii is also commonly parasitic on two or three species of 

 the same leaf-hoppers. One or two species of Cynipids have 

 been taken, probably species of Aglaotoma, and most likely 

 parasitic on the larvae of the small flies of the genus Drosophila, 

 in company with which I have elsewhere noticed them. A 

 Diapriid is also probably a parasite on some Dipterous insect. 

 In the Chalcid group we may note species of the genera Toxenma 

 and Neolelaps, and several of Eupelmus. The latter are inter- 

 esting from their diversity of habits, some being parasites of 

 Coleopterous larvae, some of Chrysopides, and some of Orthop- 

 terous eggs. Anastatus koebelei is a common parasite in 

 Locustid eggs, and of two other Eupelmines (one forming the 

 rather remarkable genus Solindenia) the hosts are not known. 

 An Astichus, and four or five other Eulophids of various groups, 

 occur. Polynema reduvioli is often seen on the wing, and two 

 other mymarids, one of which is parasitic in leaf-hopper's eggs, 

 have also been taken. 



The Ichneumons known in the locality are very few, Evania 

 sericea, a cockroach parasite, has not yet been found in other 

 countries. Echtkromorpha macuUpennis and Pimpla hawaii- 

 ensis, the Ophionines Enicospilus mauicola, kaalae, dispilus, 

 molokaiensis and dimidiatus are all parasites of various species of 

 Lepidoptera, Omiodes, Agrotis, Vanessa, and Scotorythra being 

 attacked by them. One or two species of Limnerium are 

 common parasites of various Pyralids and one or more species 

 of Atrometus may also be found. 



The two common Braconids parasitic on Longicorns of all 

 kinds, and Chelonus blackburni and Phanerotoma, though described 

 from the islands, are certainly all introduced, but the little 

 apterous Ecphylopsis is, no doubt, endemic. 



COLEOPTERA. 



The native beetles of Tantalus have been a"good deal collected 

 and many species are to be found in the forest. Some of these 

 are only found on or about this locality, or at least are much 

 more abundant here than elsewhere. This seems to me to be 

 partly due to the fact that the rainfall being largely precipitated
