OF CADDIS-FLIES DESCRIBED BY LTNNiflUS.

are opposed. Hagen has conjectured that it may be a Psocus ; 

 and the words "antcnn.T, leutc iuspectfc villosre apparent; os ut 

 in reliquis cum palpis " favour this opinion; but tlie species is not 

 to be settled with certainty. I think it may be Stenopsocits im- 

 maculafus, Stepb. 



Linnaeus has furthermore described an insect as Tinea Hoher- 

 fella (No. 1394) that cannot be Lepidopterous, for neither in 

 Sweden nor in Europe is there to be found a species of that order 

 to which the description will apply. It may have been a " I*hry- 

 ganea'' that Linn.ieus had before him, and we know that he often 

 made a comparison between the Phryganecc and Lepidoptera. It 

 may therefore not be strange if we find him describing a " Fliry- 

 yanca'^ as a Tiiiea.'' The words "antennae longissimae" may 

 therefore signify some species of Leptoceridoe. The Tinece {JDe- 

 geerella, Sivammerdamella, &c.), amongst w^hich he places the spe- 

 cies, have a striking resemblance to this family. The words " alae 

 fuscae sen nigrae, vix manifesto cinereo-inauratae, macula alba ad 

 augulum ani " are only applicable to Leptocerios aterrimus, Steph., 

 or L. dissimilis, Steph. ; but the words " antennis albis " do not 

 agree. How^ever, the Linnaean terminology is not as accurate as 

 that of the present day, and the antennae of L. dissimilis appear 

 to be white and unicolorous if viewed in a certain light. I 

 am convinced that this is the Linnaean species ; the size is the 

 same, and the words " alae vix manifesto cinereo-auratae " indicate 

 the pale brown iridescent pubescence of the wings. 



Notes hy E. M'Lachlan. 



It was, I think, partly at my suggestion that my valued corre- 

 spondent Pastor AYalleugren undertook an analysis of the Swedish 

 Trichopterous insects described by his great compatriot. He had 

 already casually alluded to several species in his notes on those 

 described by Zetterstedt {cf. ' Ofversigt af K. Yet.-Akad. Eor- 

 handlingar,' 1870, No. 3). The foregoing notes have es^jecial re- 

 ference to the nomenclature adopted by me in my ' Eevision and 

 Synopsis of European Trichoptera,' now completed as far as the 

 Linnaean species are concerned. In this work I have generally 

 adopted Pastor "Wallengren's already published views, on the prin- 

 ciple that a Swedish entomologist should be the best able to elu- 

 cidate the Linnaean species ; moreover I satisfied myself that these 

 views were sufficiently borne out by the original descriptions ;
