the old Swedish collections both species are mixed under 

 " grandis\' but grandis auct. may continue to bear the name, the 

 description agreeing. Both are common in Sweden, especially 

 in "Scania." 



Phrygaxea nnoMBiCA (No. 148G). — According to Mr.M'Lach- 

 lan Limno^hilus mannoratus, Curt., and L. stthce?iiraJis, Brauer, 

 exist in the Linnrean collection, but not L. rliomlicus auct. The 

 first-named bears the label " rJiomhica " in Sir J. E. Smith's hand- 

 writing, and the No. "741" in that of Linnaeus, corresponding 

 with the 1st edition of the * Eauna Suecica.' Nothing in the de- 

 scription indicates that he had suhcentralis before him when 

 writing it ; and it is, moreover, a very rare species in Sweden, of 

 which I have as yet seen only three specimens. L. marmoratus 

 has usually a very dark pterostigma, of which Linn?eus makes no 

 mention, nor does he allude to the dark irrorations so marked in 

 the dorsal area of that species ; and it cannot therefore be his 

 rliomhica. But it may be rliomlicus auct., to which only the 

 words " in medio alse exteriores macula rhombica albida obliqua, 

 et pone hanc alia albida vix notabilis — supra et pone maculam 

 alarem aliquid fusci" will apply. .The latter words evidently 

 allude to the dark marks at the fenestrate spot as seen in L. 

 o^Jiomlicus auct., which should continue to bear the name, not- 

 withstanding that it is not represented in the Linnaean collection. 



Ph. bimaculata (No. 1487). — This, like many other Linnean 

 species, has been misinterpreted. The name is commonly referred 

 to Neuredipsis himaculata auct., although the description says"nou 

 autem inter minimas,'" and the minute species knowm to Linnaeus 

 are compared by him with Musca or Culccc. N. himaculata auct. 

 is not larger than Ph. longicornis, azurea, or alhifrons, L. ; and if 

 he had intended it, he would have described it as " inter mini- 

 mas " without the negation ; and furthermore, concerning the 

 double spot on_ the wdngs, he would have said " altera sujpra al- 

 teram " (perhaps inserting the w^ord " oblique "), and not " altera 

 'pone alteram," as he does, "With Linnaeus the anterior margin of 

 the wing is the " mar go inferior and the posterior (or inner) 

 margin is the '* margo exterior vel superior ;" so that in describing 

 the JVeiireclipsis he would have used " supra and not '^pone,'' 

 as regards the spots, as he does in his other descriptions ; for in 

 Neureclipsis one spot is on the disk of the wing, and the other 

 on the anterior margin only a little before the former obliquely
