seems to me to reudcr such a connexion most unlikely, whereas 

 tlicy are not opposeel to the exiiinplo in the collection, \vhich 

 also still shows the " puuctum album " (the. spot in the Gth api- 

 cal cellule). Therefore, notwithstanding the objection I have 

 taken to the application of the name striata, it may be that he 

 really intended by it the insect now so called ; and I would con- 

 tinue to so apply it instead of upsetting long existing nomen- 

 clature by transferring it to ilie species we know as Neuronia rufi- 

 crus. Hagen (I. c.) enters largely into the references in the 

 'Systema;' it should be added that Linne also cites (in MS.) 



Scopoli, fig. 688 " (from the rare and unpublished vol. of figures 

 to that author's w^ork), which appears to me quite unrecognizable. 



Phrtganea geisea (No. 1484). — There exists in Linne's collec- 

 tion an insect bearing a label " No. 739 " (corresponding to the 

 'Fauna,' ed. 1) in his hand, which is certainly not the grisea uni- 

 versally so called by authors. It is a small S (similar in size to 

 most of the Swedish specimens I have seen) of LimnopJiilus stigma^ 

 Curtis {of. my ' Revision and Synopsis,' p. 58, footnote) ; and con- 

 fessedly Pastor "Wallengren's ideas appear to have at least a^nVwa 

 facie appearance of being well grounded ; such a change w^ll, 

 liowever, be little palatable to authors. 



Ph.bimaculata(No. 1487). — Pastor Wallengren would consider 

 this as representing LimnopJiilus griseus of authors. I, on my 

 part, hesitate to adopt his view. It appears to me that the words 

 relating to the spots, " altera pone alteram," are applicable to the 

 position of these markings in Neureclipsis himaculata of authors. 

 In effect the prepositions " pone " and " supra " would be equally 

 correct ; for the second spot is placed decidedly after or behind 

 the first, although more towards the costal margin ; and, more- 

 over, the words " lunularis " (not quoted by Wallengren) and 

 " flava " are more suitable to the NeurecUpsis than to the Limno- 

 philus. Nevertheless it is quite true that the insect in Linne's 

 collection, referring to his grisea, is the latter {cf. ray ' Eevision 

 and Synopsis,' p. 87, footnote). Supposing Pastor Wallengren*s 

 views be accepted, the NeurecUpsis will take the specific name of 

 Jigurinensis, Pabricius. Linne has added the following MS. 

 citations : — " De Geer,Ins.ii. p. 5G8, tab. 15. fig. 5" {Leptoceridce) ; 

 " Schiiff. Icon. tab. 109. figs. 3, 4 " (probably LimnopJiilus sparsus)^ 

 and " Geofi". Ins. ii. p. 248. no. 5 " (Leptocerus) .
