These butterflies, upon reaching maturity, apparently follow instictively the eastward 8 march until the main army is met. On June 8 they were noted in greatest numbers along the coastal sections of eastern Florida and on June 9, 10 and 11 millions of them were noted by travelers coming from Nassau, Bahama Islands, fluttering above the Gulf Stream heading southward. It would be extremely interesting to understand the purpose of such migrations: where the butterflies come from, that is, how far north do they begin to gather and migrate and where is the place for which they are headed. Is it Cuba, or South America, or do most of them become exhausted and consequently a prey to fish in their journey over the ocean? But little is known in regard to the food plants of the caterpillars of these butterflies. They may feed on some wild species of plants related to the cabbage and mustard. Noting that so many appear from the Everglades, it is not unlikely that some native host growing in that section of the state is responsible for the breeding of great numbers. THE PROPERNAME AND DISTRIBUTION OF THE FLORIDA ' FLOWER THRIPS J. R. WATSON In the literature-on Florida insects prior to 1913 our fiower thrips was not distinguished from the northern species Frankliniella tritici (Fitch), then called Euthrips tritici Fitch or Thrips tritici Fitch. For instance, Quaintance in Bulletin No. 42 of Fla. Agric. Exp. Sta. refers to a thrips damaging strawberries at Lake City under that name. But his Figure 4, from a microphotograph, shows the second antennal segment with sufficient clearness to prove that it...
