Observations were continued upon the living material brought back from the Lough Mask Expedition, and, notwithstanding interruptions in their continuity, I still hope that interesting results, elucidating the life-history of certain Tabanido. will accrue.
Experiments and observations were also carried on, from September to January, in the hope of answering the vexed question as to how the common house-fly tides over the winter. These, unfortunately, could not be concluded; but, so far as they went they showed (1) that both the larval and the pupal stages are much prolonged; (2) that, with a given batch of eggs and its issue, there is remarkable individual difference in the duration of every stage-particularly in the pupal stage; (3) that such flies as emerged, though they fed freely, were sluggish, showed no disposition to breed, and did not live longer than a month; and (4) that at the very end of January there were still numerous living pupa-the issue of eggs that had hatched at the end of September. These incomplete observations lend support to the view that the house-fly survives the winter chiefly in the pupal stage.
The donations have been few. They include some valuable specimens of blood- sucking insects and their larvæ from the Entomological Research Bureau; some preparations and dissections of Lynchia, showing the development of the hæmo, proteus of the pigeon, from Mrs. Helen Adie; a useful series of ticks and insects from Dr. R. E. Drake-Brockman; and various desirable specimens from Dr. M. Brain Mitzmain, Dr. J. E. S. Old, Dr. C. Strickland, and Dr. R. Willan.
