728 TASTOK n. D. J. WALLENGEEN OK SPECIES 



Central Sweden, is larger tlian reticulata. If Linnsens had striata 

 auct. in view, lie would undoubtedly have said " magna," as he 

 does in his description oi grandis, next to which he would, more- 

 over, have placed the species. Neuronia rujicrus should there- 

 fore take the name iV". striata. 



PHETaANBA GEiSEA (No. 1484). — The intention of Linnaeus has 

 been misunderstood in referring the name to the grisea of almost 

 all succeeding authors. If the latter were intended it is not ex- 

 plainable why no mention is made of the " fenestrate spot " and 

 "anastomosal space," which are very evident in that species j 

 and in connexion with this should be added the words "mediae 

 magnitudinis est," in comparison with the other species known 

 to him. In the males of grisea auct. it is true that these mark- 

 ings are more obsolete than in the females, but very rarely are 

 they obliterated altogether. The dark pterostigma is, moreover, 

 but faintly indicated, whereas the grisea of Linnaeus has a distinct 

 " macula marginali nigra " on the anterior (inferior in regarding 

 an unexpanded insect) margin. Moreover, in describing the 

 grisea of authors, he would not have said " alee superiores yrzsece," 

 but rather " alae cinereo-testaceae," or " subferrugineae," as used 

 elsewhere. He would not have said "corpus griseum," but 

 "corpus fuscum " or "nigrum." Thus his description cannot 

 concern grisea auct., but another species with a strongly-marked 

 pterostigma ; and the only Swedish species possessing this cha- 

 racter is Limnophilus stigma, Curt. The wings of the Linnaean 

 insect are " griseae ;" and the sense of this is to be learned from the 

 description of Fh. rJiomhica, where he says " alae subluteae sive 

 grisece.^' Fh. rJiombica never approaches grisea auct. in colour, 

 but often resembles L. stigma in this respect, the wings of which 

 are, moreover, " fusco obsolete nebulosae," as is said; and the 

 colour of the body is similar, as is also indicated by the words 

 " alae superiores (uti totum corpus) griseae." The example in the 

 Linnaean collection is therefore typical, bearing, as it does, the 

 label ^'grisea" in Sir J. E. Smith's handwriting; and No. 749, 

 in Linnaeus's handwriting, corresponding to grisea in the 1st 

 edition of the ' Pauna Suecica.' Limnopliilus stigma, Curt., should 

 thus take the name of L. griseus, L. 



Ph. gbandis (No. 1485). — There can be no question as to what 

 Linnaeus intended ; but it is evident that he had not separated 

 striata auct. (=bipimcfata, Eetz.) from grandis auct. In all
