182, THE ENTOMOLOGIST’S RECORD. 
§ Strigata, Miull., ‘‘ Faun. Frid.,” p. 51 (1764).—Unfortunately this 
name is invalid, for Scopoli published another striyata among the 
Geometers the year previous (=pusaria, Linn.). 
Vernaria, Fb., ‘‘ Syst. Ent.,” p. 620 (1775).—Apparently not per- 
sonally known to Fabricius, but founded on Linné and on Roesel’s 
fieure. It agrees in the main with striyata, Mull., and perhaps 
strengthens the possibility at which I have already hinted in dealing 
with vernaria, L., but how little claim Fabricius has to be regarded 
as an authority on this particular name is shown by the fact that 
“‘vernaria, Linn.,’’ in the Banks collection (probably named, or at 
least sane gonad by Fabricius) is a Metr ocampa margaritata | 
“Thymiaria (Schiff.), “‘ Schmett. Wien.,” p. 97 (1775).—Thymiaria, 
Linn., cited by Schiffermuller, was founded on a mixture of Vhalera 
fimbrialis, Scop., and Hemithea strigata, Mull., and even though 
Linné’s types belong to the latter, the name was founded on the 
conception derived from Frisch’s thyme species (=/imbrialis, Scop.), 
and a sufficient case can therefore be made out for the application of 
Merton Rule 24, ‘‘ A name which involves a false proposition . . . 
may be changed.” 
Aistivaria, Hb., “ Btr.,” 1., pt. 4, p. 22, pl. ui. R. (1789).—This 
name is in every w ay ee euae and was in general use on the 
continent until the modern ¢ra of priority-law. It should without 
doubt supersede strigata, Mull., unless the doubtful claims of vernaria, 
Linn., can be accepted. 
4. Greometra (Nemoria) viridata, Linn.—lI have already pointed out 
that the accepted synonymy of this species has been upset by Werne- 
burg for nought; I may add that it is not clear why he renames it 
prasinata ; even if his assumption that it was not the true viridata of 
Linné had been well-founded, [ do not see anything against the 
employment of Hiibner’s name of cloraria (tig. 852). 
[ subjoin a summary of the synonymy as given in this article ; the 
remainder of the specific names stand as in Staudinger’s Cataloque.

Migration and Dispersal of Insects: Lepidoptera. 
By J. W. TULT, F.E.S 
So far as one is able to get at the real facts (¢.c., apart from the 
opinions of observers) one is able to conclude that the movements of 
Anosia archippus, in North America, are very similar to those of 
Pyrameis cardui in Kurope. Like the latter, it appears to have its own 
subtropical (and tropical) permanent home, and more or less each 
season, but more particularly in occasional seasons, to send out large 
numbers from these centres in northerly, easterly and westerly 
directions, reaching well up into Canada and the North-west Territory,
