This is an introduced ant which is overrunning the islands, and which exterminates the native insect fauna. Mr. Perkins finds that earwigs alone can withstand this ant, and his only chance of collection of endemic insects is to get ahead of the ant. In the 'Report' for 1900 it is stated that on his return from a visit to England Mr. Perkins found that great changes had taken place in the islands during his absence, and that the forests were being extensively destroyed and replaced by sugar-cane. The grants by the British Association have been supplemented by grants from the Government Grant Committee administered by the Royal Society, and from the trustees of the Bernice P. Bishop Museum in Honolulu. Eight parts of the three volumes intended to form the 'Fauna Hawaiiensis' have now been published and others are in the press. The inception of this investigation was due to Professor Alfred Newton, and if he had not persisted until he succeeded, comparatively little would ever have been known about the fauna of the Hawaiian islands.
In a communication to Nature Mr. Perkins says that few countries have been more plagued by the importation of insect pests than the Hawaiian Islands; in none have such extraordinary results followed the introduction of beneficial species to destroy them, of the effect of which he gives many instances. He goes on to say:
