Economic Pest

One of the few Canadian entomologists to study thrips was R. C. Treherne who was one of the group of workers to investigate the pear thrips when it first became an economic pest in North America. In the course of his work he collected and studied thysanoptera. His collection, supplemented by exchanges with other workers, formed the basis for the material now in the Canadian National Collection at Ottawa. The writer is indebted to curators of this collection and particularly T. N. Freeman, for the generous loan of valuable specimens for study, particularly the types of Treherne. The Moulton collection is now deposited at the San Francisco Academy of Science, Golden Gate Park, San Francisco, California. We also wish to thank Dr. E. S. Ross, curator, for the opportunity of studying the types of Taeniothrips tahoei Moulton, Tae. pingreei Moulton, Tae. aureus Moulton, and Frankliniella californica Moulton.

Tsunami Signal

Abstract We estimated the origin time of the 1854 Ansei–Tokai tsunami from the tsunami waveforms recorded at three tide gauge stations (Astoria, San Francisco, and San Diego) on the west coast of North America. The tsunami signal is apparent in the San Francisco and San Diego records, and the arrival time was 0–1 p.m. Greenwich Mean Time (GMT) on 23 December 1854, whereas the tsunami signal of Astoria is ambiguous, and the arrival time could not be determined from the waveform. The simulated waveforms on the basis of nonlinear dispersive wave theory by assuming an origin time of 0 a.m. GMT on 23 December arrived earlier than the observations. Cross-correlation functions between the observed and simulated waveforms recorded at San Francisco and San Diego showed a time gap between them of approximately 30 min. Based on these results, we concluded that the origin time of the 1854 Ansei–Tokai tsunami was approximately 00:30 a.m. GMT or 09:46 local time on 23 December. Our result is roughly consistent with reports by a Russian frigate anchored in Shimoda Bay, ranging the earthquake between 09:00 and 09:45 and the tsunami between 09:30 and 10:00. The earthquake was also reported in historical Japanese documents ranging from 8 and 10 o’clock in local time.

Collections made along the coast of California have revealed the presence of a species of Pseudosphaeroma Chilton, 1909, a genus common in New Zealand coastal waters. The genus is entirely Southern Hemisphere in distribution, and this record reports the introduction of a species of Pseudosphaeroma into the San Francisco and Central Coast region of California, the first reported occurrence of the genus as an invasive taxon, and the first record of the genus from the Northern Hemisphere. The genus is also recorded for the first time from the Galapagos and Argentina.
