or CADDIS-rLIES DESCEIBED BY LINNiEITS. 729 



the old Swedish collections both species are mixed under 

 ^^ grandis]' 'hwi grandis auct. may continue to bear the name, the 

 description agreeing. Both are common in Sweden, especially 

 in " Scania." 



Phetganea khombtca (No. 1486). — According to Mr. M'Lach- 

 lan LimnopMlus onarmoratus, Curt., and L. suicentralis, Brauer, 

 exist in the Linngean collection, but not L. rJiomhiciis 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 sicbcentralis before him when 

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

 v/hich I have as yet seen only three specimens. L. marmoratus 

 has usually a very dark pterostigma, of which Linnaeus 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 

 rho)nhica. But it may be rJioonhicus auct., to which only the 

 words " in medio alas 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. 

 rJiombicus 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 Neureclipsis limaculata auct., although the description says " non 

 autem inter minim as, ^^ and the minute species known to Linnaeus 

 are compared by him with Musca or Oulex. JV. himaculafa auct. 

 is not larger than Fh. longicornis, asurea, or alUfrons, 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 wings, he would have said " altera supra al- 

 teram " (perhaps inserting the word " oblique "), and not " altera 

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

 the wing is the '' margo inferior,'" and the posterior (or inner) 

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

 i\e Neureclipsis 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
